An infra-red vertical aerial photograph of the Spring Creek area in Wakulla
County. Taken in April, 1972 from an altitude of 3,000 feet, the upwelling
spring-flow, known as Spring Creek Rise, is easily located because of water
temperature differences. The spring shows as the dark circular area just
offshore from the end of State Highway 365.

LETTER OF TRANSMITTAL


Bureau of Geology
Tallahassee
August 22, 1978


Governor Reubin O'D. Askew, Chairman
Florida Department of Natural Resources
Tallahassee, Florida 32304

Dear Governor Askew:

The Bureau of Geology, Florida Department of Natural Resources is pub-
lishing as Bulletin No. 31 Revised, "Springs of Florida," prepared by J. C.
Rosenau, G. L. Faulkner, C. W. Hendry, Jr., and R. W. Hull.
The first comprehensive report on Florida's springs was published in 1947.
Since that time much additional data on our springs have been gathered and
is incorporated in this publication. This bulletin not only updates these data
but also includes data on previously undescribed springs.
This revision represents a major cooperative effort between the U. S.
Geological Survey and the Bureau of Geology that has taken several years to
complete. It will satisfy a public demand for current information on the
nature and occurrence of the springs in Florida.

Respectfully yours,



Charles W. Hendry, Jr., Chief

PREFACE


The first comprehensive report of Florida's springs, which contains both
a story of the springs and a collection of facts about them, was published
thirty years ago (Ferguson and others, 1947). Since then, much additional
data on springs have been gathered and the current report, Springs of Flor-
ida, makes a wealth of information on springs available to the public.
Springs of Florida, prepared by the U.S. Geological Survey in cooperation
with the Bureau of Geology, Florida Department of Natural Resources, pub-
lishers, and the Bureau of Water Resources Management, Florida Depart-
ment of Environmental Regulation, is intended to provide sufficient back-
ground information for a lucid understanding of the nature and occurrence
of the springs in the State.



















In accordance with standard practice, referenced reports are cited in the
text of this report only by author and date of publication. The report title
and publisher are listed in the "References" section of the report.

SPRINGS OF FLORIDA


By
J. C. Rosenau, G. L. Faulkner,
C. W. Hendry, Jr., and R. W. Hull

SUMMARY AND CONCLUSIONS
Florida has 27 first magnitude springs that discharge water from a thick
sequence of limestones known as the Floridan Aquifer. Their total average
flow is 9,600 cubic feet per second or slightly more than 6 billion gallons per
day. Although an accurate world inventory is not available, it seems that
Florida's major springs exceed in number and in quantity of water discharged,
those of other states or nations.
Discharge from all of Florida's 300 known springs is estimated at 12,600
cubic feet per second or 8 billion gallons per day. By comparison, all fresh
ground water pumped in 1975 in Florida totaled 3.3 billion gallons per day.
Records indicate that the major use of the springs is recreational with little
significant change in the past 30 years. Nor has their been any significant
state-wide change in springflow, although some springs in populous south
Florida do show reduced flow.
Few changes since the 1940's appear to have occurred in the quality of the
spring water, the springs reflecting the good quality normal to Florida's
ground-water aquifers. None were found to be contaminated with pesticides.
herbicides, or metals.
The Floridan Aquifer is frequently cavernous and a conductor of immense
quantities of water throughout most of the state. The rocks of this artesian
aquifer system, or ground-water reservoir, are geologically Tertiary in age.
The springs are generally concentrated along the major streams and the west
coast of the state. The Suwannee River valley has at least 50 springs that are
subject to flooding and even to reversal of flow at high river stages. Nine are
discharging more than 100 cubic feet per second (first magnitude flow).
Spring locations are shown by hydrologic subregion and by numbers
utilized for spring identification and computer recovery of filed spring data.
The description of over 200 springs include quality of the water data, flow
rates, and photographs. Known submarine springs are identified, as are a
group of pseudosprings (wells that are commonly and incorrectly identified
as springs).
"Springs of Florida" is an inventory of an important natural resource. New
information was obtained for the report during extensive field travel; and










BUREAU OF GEOLOGY


data collected through more than 30 years are summarized and included in
the spring descriptions. These data are presented for use by scientists, the
water manager, and for the casual student of Florida's springs.

INTRODUCTION
Springs are fascinating and of value to man not only because of their
beauty and water-supply potential, but also because of their recreational and
reputed medicinal value. Ponce de Leon is said to have sought a spring
called the "Fountain of Youth" in the territory that came to be called Flor-
ida. The large springs encountered by the early Spanish explorers in Florida
must have appeared as immense watery cathedrals. And equally amazing
must have been the crystal clear rivers that issued from the cavernous depths
of the springs that were teaming with colorful fish, sunning turtles, and
alligators. To the Indians, the spring sites offered ideal places for villages,
providing food, water, and transportation.
Waddells Mill Pond Spring in Jackson County, for example, was reportedly
the site of a Chatot Indian village; the once sulfurous water discharging
to the Suwannee River at White Springs in Hamilton County has been used
as medicinal by white man and Indian; and Little Salt Springs and Warm
Mineral Springs of Sarasota County were used by pre-historic man.
Countless writers have described Florida's springs as among her principal
natural and scenic resources. Some of the larger springs have been developed
as tourist attractions: from glass-bottomed boats the depths of springs can be
examined through the clear water, and aquatic life can be observed in its
native habitat, apparently unaware of the observer. The uniformly comfort-
able temperature of the spring water, its clarity, and the underwater cave
systems are natural year-round attractions to the swimmer and the scuba
diver.
As part of their continuing cooperative program, the Water Resources
Division of the U.S. Geological Survey and the Florida Department of En-
vironmental Regulation, previously the Florida Department of Natural Re-
sources, the Water Management Districts, and other state and local agencies
collect information on spring flow and water quality. In the section of this
report allotted to the descriptions of individual springs, there is given the
location, physical description of the spring, and usually a picture of the
spring and spring area, spring flow and quality tabulations, and the temper-
ature of the water.
The springs included represent a comprehensive inventory of those made
known to the authors through 1977. There are other springs: some too small
to be significant, others that are little known or secreted away in the wood-
lands and the marshlands of the state, and many others that lie undetected
in the beds of Florida's rivers, in its estuaries, and offshore.










BULLETIN NO. 31


For those who have only a passing interest in Florida springs and would
ask, for example, why Florida has so many springs and where does the water
come from that the springs discharge,,this report will be helpful. Fot those
who have.the responsibility for managing water resources and planning for
their conservation for future generations, this report will be invaluable: it
provides necessary data for such managing and planning as relates to the
utilization and preservation of the springs. Records of spring flow and water
quality provide a good measure of long-term hydrologic trends. A spring is
generally much more representative of the character of a large part of an
aquifer than is a well. For the serious student of springs, the report includes
an abundance of data carefully collected, analyzed, and presented; hopefully
in a format that will make the information easy to read and use.
Much of the information on springs of Florida are collected as part of the
continuing data program just described. The data-collection activity is mod-
ified as needed-springs are added to or deleted from the program as neces-
sary, depending on the need for information. The spring data published in
1947 (Ferguson and others) have been substantially updated by this report.
A special effort was made to revisit the springs, to check whether the 1947
data are still valid and to visit other significant springs. Data collected sub-
sequent to the publication of this report are available in the offices of the
Florida Department of Environmental Regulation, the respective Water Man-
agement Districts, and the Florida District Office of the Water Resources
Division, U.S. Geological Survey.

A statistical analysis of Florida's springs was not made to determine their
past use in contrast to their present use, nor to determine the quantity of
water discharged now in comparison to their aggregate discharge 30 years
ago. There is, however, an increasing interest by state and local governments
in the purchase of springs and contiguous lands for public use. And there is
also a demand by private individuals and organizations for homesites at
springs, for their recreational development, for overnight or travel parks near
springs, and for large-scale housing projects.
An example of the latter is the recent closing off of Peacock Springs in
Suwannee County and the development of a 120-acre tract surrounding the
springs into 20 homesites (M. Shifflatte, written commun., April 1977).
There does not appear to be an overall change in springflow statewide, but
in some populated areas of south Florida areas of heavy ground water
pumping -springs have gone dry or have shown marked reduction in flow:
Kissengen Spring in Polk County and Health Spring in Pinellas County are
examples of springs whose flow has ceased.


SPRING CHARACTERISTICS

A spring is the water discharged as natural leakage or overflow from an
aquifer through a natural opening in the ground. The opening may be so
small that it yields only enough water to create a wet seep or trickle. On the
other hand, the opening and the associated subterranean cavern that is
common to Florida may be so large that the spring flow is the source of a
large river. Some examples are Silver Run from Silver Springs; Blue Run
from Rainbow Springs; Weeki Wachee River from Weeki Wachee Springs;
and Wakulla River from Wakulla Springs. This type of ground-water dis-
charge is typical of Florida's karst topography a land of numerous sink-
holes, caves, springs, and underground drainage through large cavities in the
limestone and dolomite rocks underlying the surface soils.
O. E. Meinzer classified springs by magnitude, from one to eight, on the
basis of their volume of flow or discharge. The following tabulation was
modified from Meinzer (1927, p. 3):

Magnitude Average Flow (Discharge)
1 100 ft3/s (cubic feet per second) or more
2 10 to 100 ft3/s
3 1 to 10 ft3/s
4 100 gal/min (gallons per minute) to 1 ft3/s (448 gal/min)
5 10 to 100 gal/min
6 1 to 10 gal/min
7 1 pint to 1 gal/min
8 Less than 1 pint/min










BULLETIN NO. 31


The United States has about 78 first magnitude springs. Table 1 lists the
9 states that have first magnitude springs, the number's known to exist in
each, and the reference from which these data were obtained. The springs
discharge from limestone, basalt, or sandstone aquifers. In writing about the
springs of Texas, Brune (1975) explains how man's ever-increasing need for
water has reduced or stopped the flow of many springs, including two of the
four first magnitude springs that Texas had in 1947 (Ferguson, p. 37).
According to Brune, the first major effect on the springs of Texas a de-
crease in flow- was caused by deforestation of the land by early white
settlers. Since then, water use, in all its many forms, has changed even
increased the flow of Texas springs. The flow of San Felipe Springs, for
example, dropped from an average of 149 ft3/s in 1900 to 22 ft:/s in 1953,
then increased to 82 ft3/s in 1971. Goodenough Spring is now (1977) inun-

dated to a depth of 150 feet by waters of a nearly completed reservoir that
appears to be increasing the flow of some springs, including San Felipe
Springs, by increasing recharge and by diverting the flow of Goodenough
and other inundated springs to San Felipe Springs. If San Felipe regains
first magnitude status, Texas will have three the others are Comal Springs
and San Marcos Springs.
Of the 78 first magnitude springs in the United States, Florida has 27, the
most for a single state. Florida seems to have the largest number of springs
and also the largest spring in terms of average flow: a submarine spring at
Spring Creek in Wakulla County yields about 2,000 cubic feet per second.










BUREAU OF GEOLOGY


Table 2 lists the first magnitude springs in Florida and figure 11 shows their
general locations. Although a complete world inventory of springs and spring-
flow is not available, Florida's 27 first magnitude springs appear to exceed in
numbers and in quantity of water discharged, those of all countries of the
world (table 3).
The classification of Florida's springs by Meinzer's magnitude of discharge
system is the simplest way to compare spring impact on the water resources
of the State. Florida's 27 first magnitude springs are discharging at an esti-
mated rate of more than 9,600 cubic feet per second or 6.2 billion gallons
per day. Some 300 Florida springs are discharging an estimated 12,600
cubic feet per second or over 8 billion gallons per day, which exceeds the
total amount of freshwater withdrawn for all uses in Florida in 1975 by a
billion gallons per day. S. D. Leach (1977) summarized Florida's 1975 fresh
ground-water pumpage for all uses at 3.3 billion, and total fresh surface
water at 3.6 billion gallons per day.
About 70 springs are classed as second magnitude, and they discharge
about 2,700 cubic feet per second or 21 percent of the total springflow. More
than 190 springs are third magnitude or less, and they discharge more than
300 cubic feet per second, or 3 percent of total springflow.
Springs also are categorized according to the type of aquifer from which
they derive their water. As such there are two general types, water-table
and artesian springs. Rain that percolates through e sediments, suc
as lately reach a relatively impermeable bed, such as clay.
The water then moves down gradient along the top of the impermeable bed
to a place of outcrop where the water issues as a spring or seep. This is a
water-table or non-artesian type spring. In Florida their flow is normally
small and variable. Where water is confined in permeable sediments beneath
impervious confining beds, and is under sufficient hydrostatic pressure to rise
to the surface through a natural breach in the confining beds, an artesian
spring is formed. Most of Florida's large springs are of this type, as are
many of the smaller ones. (fig. 1). Florida has numerous artesian submarine
springs along its coasts (fig. 17). Where the yield of a submarine spring is
great enough, it creates a "slick" or "boil" at the water surface thus identi-
fying the spring location. Submarine springs are known to exist on the
Atlantic Coast, offshore at Crescent Beach; and on the Gulf Coast, offshore
of Aripeka and from Lee to Wakulla counties.
Springs may be classed in many other ways, including chemical char-
acteristics if, for example, their waters are salty or sulfurous; by tempera-
ture nonthermal or thermal, and thermal springs may be "warm" or
"hot"; or by the type of opening through which the water surfaces seep-
age, tubular, and fracture.

The natural flow of springs is controlled by hydrologic and geologic
factors, such as amount and frequency of rainfall, the porosity and perme-
ability of the aquifer, the hydrostatic head (pressure) within the aquifer,
the hydraulic gradient and, in the case of artesian springs, to a lesser degree
to influences outside the aquifer, such as atmospheric pressure systems and
oceanic tides. The flow of springs is also changed, usually decreased, by man
through such means as pumping from wells that tap the aquifer.
Fortunately, Florida has sufficient rainfall distributed through the year to
keep its aquifers recharged sufficiently to maintain perennial flow at most
artesian springs. Though the State does experience water-supply problems in
some areas where ground-water withdrawal is excessive, this condition is the
exception, and variations in discharge rates of artesian springs have been
remarkably small. The flows of large springs may be substantial even through
periods of drought. This is understandable when the large volume of water
stored in Florida's artesian aquifer system is compared with the relatively
small discharge of its springs. The aggregate discharge from all the artesian
springs is not enough to deplete the aquifer between periods of recharge. On
the other hand, the variations in flow of water-table springs may be great in
response to rainfall variations and may cease flowing in the dry season be-
cause of the relatively small size and low storage capacity of many water-
table aquifers.
The openings or voids in the rock through which ground water moves
may vary in size and relation. They may be as small as the original pore

spaces between the grains that make up the rock or as large as the sizeable
caverns that result from dissolution by circulating water. The size of the pore
spaces or caverns extending from the spring vent back into the aquifer and
the degree of interconnection (permeability) among the void spaces are con-
trolling factors in spring flow.
Another influence on the amount of flow from springs is the differential
between the hydrostatic head at the spring vent and that in the recharge or
replenishment area. Closely related to the head is the hydraulic gradient or
degree of slope of the water-table in an unconfined aquifer or of the potentio-
metric (pressure) surface of an artesian aquifer. Both the head differential
and gradient are governed by the differences in elevation between recharge
and discharge areas and on the permeability of the aquifer.
The influence of atmospheric pressure system ond oceanic tides are minor
but may affect the yield of artesian springs. High atmospheric pressure sys-
tems and high tides load and thereby compress the aquifer. This compression
tends to decrease the pore space and to force water out of the aquifer, thus
increasing spring yields slightly. Where high tides or high river stages inun-
date a spring vent, spring flow is decreased, may be temporarily shut off, or
the spring may take water as happens along the Suwannee River.
Man, in supplying his water needs, can have catastrophic effect upon the
flow of springs. Large water withdrawals from wells near a spring can re-
duce pressure in the aquifer to a level below the spring orifice, thus stopping
its flow. Subsequently, if withdrawal is reduced sufficiently, a spring may
start to flow again. For example, Kissengen Spring near Bartow in Polk
County stopped flowing after some nearby wells that tap the same aquifer as
the spring began to be heavily pumped. When pumping ceased for several
months, the flow of Kissengen Spring resumed, only to cease once more when
the wells were again pumped.
Ground water continually moves from points of replenishment to points
of discharge. In Florida, natural discharge occurs to other aquifers, to the
Atlantic, the Gulf, to streams, lakes, from seeps, and springs, and man
causes discharge through the pumping of water from wells. Ground water is
not in dead storage in the aquifer; circulation of water in the ground causes
dissolution of the host rock, mostly carbonates (limestone and dolomite) in
Florida, and this material becomes a chemical constituent of the water. Be-
cause water from the carbonate Floridan Aquifer contains relatively large
quantities of dissolved material, it is considered hard compared to water in
the surface streams and noncarbonate aquifers in Florida.
Ground water issuing as springs is usually clear and clean because of the
filtering and absorbing action of the soil and aquifer materials that the water
passes through. Some springs, however, may have turbid or brown, organic










BULLETIN NO. 31


colored water typical of many surface waters in Florida. Where turbid water
or the brown tannic acid water common to swamps recharges an aquifer in
proximity to a spring, the water may move quickly through solution channels
in the aquifer to discharge at the spring vent little altered in quality. For
this reason, it is not uncommon to note "swamp water" discharging from
some springs in Florida, especially following heavy rainfall. A few spring
waters having relatively high dissolved solids concentrations have a whitish
cloudy appearance, possibly the result of precipitation from rapid pressure
or temperature changes when discharged. Many Florida springs are bluish,
carrying such names as Blue Spring or Blue Hole. The blue color is charac-
teristic of clear water in large quantities, as is true for air in large quantities,
and is not due to any particular impurities.
A striking characteristic of spring water is that it seems cold in the sum-
mer and warm in the winter. This is not the result of a change in water
temperature but the difference between air and water temperatures. The
temperature of spring water varies only a few degrees; even among springs
the temperature variation is small as the following tabulation illustrates:


Approximate Average
Range Temperature
(in *C) (C) (OF)
North Florida 19 to 23 21 70
Central Florida 22 to 26 24 75
South Florida 27 to 31 29 84

Spring water is at or near the temperature of the aquifer, which in tie case
of shallow aquifers is at or near the average annual air temperature of the
particular area. Spring waters from deeper aquifers tend to have higher
temperatures.
Water temperatures of a few springs in Florida are appreciably higher
than others in the state. The geothermal gradient for ground water, that is.
the rate of increase in temperature with depth, is about 1 degree Fahrenheit
per 65 feet of depth (Collins, 1925, p. 98) or 1 degree Celsius per 100 feet,
although there are exceptions to the rule. The warm springs, such as those in
Sarasota County, derive their water from deep formations due to an abnor-
mality of the host rock such as a fault or fracture which allows this warm
deep water to rapidly reach the surface.
Though Florida spring water is normally hard compared to surface or
non-carbonate aquifer water, it is not as mineralized as the ground water in
older and deeper rocks. Sodium chloride (common salt) is the principal
mineral contributing to high mineralization. Highly mineralized water has
been obtained from deep wells beneath all of Florida.











BUREAU OF GEOLOGY


GEOLOGY AND HYDROLOGY
That Florida has many springs, some of large size, is the direct result of
the particular combination of geologic and hydrologic factors that prevail in
the State. Following is a discussion of the geology and hydrology of Florida,
to the extent that these relate to the occurrence of these many springs.
Florida is the emergent part of a large platform, called the Floridan
Plateau (fig. 2), that projects southward from the continental mass and sepa-
rates the deep water of the Atlantic Ocean from that of the Gulf of Mexico.


FIGURE 2. The Floridan Plateau and its emergent part, Florida. The Ocala
Uplift, also shown, has an important influence on spring oc-
currence in the state.









BULLETIN NO. 31


The Floridan Plateau is composed of several thousand feet of nearly flat-lying
limestone and dolomite strata that are veneered with sand, clay, limestone,
and mixtures of these that are as much as several hundred feet thick. These
sediments were deposited mostly in a shallow-marine environment and, for
the most part, are not intensely lithified nor have they undergone intensive
deformation. The Ocala Uplift, an important surface structural feature affect-
ing the occurrence of many of the springs in Florida is shown in figure 2.
The upper part of the limestone and dolomite rocks of Florida constitutes
a part of a very extensive and productive ground-water reservoir identified
by V. T. Stringfield (1966) as the Principal Artesian Aquifer of the south-
eastern United States. Stringfield (1936) originally described this hydrologic
system and Parker (1946) redefined and named that part of the system in
Florida, the Floridan Aquifer.
The Principal Artesian Aquifer underlies all of Florida and extends be-
neath parts of Alabama, Georgia, and South Carolina (fig. 3). A substantial
part of the sediments veneering the Floridan Aquifer, though porous and
permeable in part, is relatively impervious and serves to confine, under pres-
sure, the water in the Floridan Aquifer over much of its areal extent. The
Floridan Aquifer supplies all the first magnitude springs in Florida (see
table 2) and most of the smaller ones. Permeable parts of the sedimentary
veneer are of local extent and in places supply small springs.

GEOLOGY

As a background for a discussion of Florida springs, a description of the
nature and attitude of the rocks from which springs flow is important. The
number, size, and location of Florida springs is intimately associated with
the stratigraphy and structure of the rock formations. For example, more
large springs are located near the Ocala Uplift (fig. 2) than elsewhere in
Florida.
The Ocala Uplift is the name applied to the structurally high Tertiary
strata in the northwest part of peninsular Florida. As the uplift evolved, the
clastic-sediment veneer on the uplift was deposited more thinly and was more
readily eroded than elsewhere in Florida. These factors left exposed or nearly
exposed at the surface the carbonate bedrock that comprises the Principal
Artesian or Floridan Aquifer.
Florida, though devoid of high altitudes and great relief, does vary in
altitude somewhat, from the very low, nearly flat, terraced coastal plains to
the high rolling hills of the interior. On the peninsula, the interior ridges
reach a maximum of 310 feet above sea level at Sugarloaf Mountain in
southern Lake County. The ridges do not extend south of Lake Okeechobee,
and so the southern tip of Florida is a low, almost featureless plain. Relief

within the coastal plain usually does not exceed a few feet, whereas in the
higher inland areas relief is a few tens of feet, commonly more than 100
feet. In northwest Florida, the highlands are on the average about 30 miles
inland from the coast. Surface altitudes range from sea level at the coast to
a maximum of 345 feet above sea level in Walton County, near the Florida-
Alabama state line.
The high interior ridges of the peninsula are the erosional remnants of
deposits laid down during the Pleistocene (ice-age) marine inundations of
Florida. The ridges are primarily composed of loose quartz sands with small
amounts of clay occurring as a matrix and locally as clay beds. These plastic
sediments, where they are sufficiently permeable, constitute water-table or
unconfined aquifers. Where the permeablity is low, owing to a high clay
content, they serve, along with underlying poorly permeable beds of Miocene
and Pliocene age, as confining beds atop the artesian Floridan Aquifer.
Throughout the Tertiary Period, the Floridan Plateau was a shallow
marine shelf upon which widespread deposits of chemically precipitated
limestone and dolomite, along with the shells and shell fragments derived
from the teeming marine life, were laid down. This deposition of very pure
calcium and magnesium carbonate continued through early Tertiary time
into the late Tertiary. At the beginning of the Miocene Epoch, ever in-
creasing amounts of sand, silt, and clay were transported into Florida by the
numerous river systems from the neighboring Appalachian Mountains to the
north. These terrestrial plastics were intermixed with the upper Tertiary
marine limestone deposits and by late Miocene time the elastics were the
dominant type of deposit. Thereafter, in most of Florida, the predominant
carbonate deposited was in the form of shells with minor amounts of chem-
ical carbonate precipitate deposited with clay to form marl.
In northwest Florida, from the Chocktawhatchee River westward, sedi-
ments are predominantly elastics and both these and the underlying limestone
of the Floridan Aquifer slope gently downward and westward into the Mis-
sissippi Embayment. Southward from the Ocala Uplift the limestones of the
Floridan Aquifer also become progressively lower, so that in the southern
part of the State, the aquifer is deeply buried beneath post-Oligocene elastic
sediments.
The great depth to the Floridan Aquifer in south Florida and westward
of central Walton County effectively eliminates the occurrence of Floridan
Aquifer springs in those areas. Water-table springs exist in these places,
however, although many of them in south Florida no longer flow owing to the
lowered water table resulting from many years of heavy ground-water draft.











BUREAU OF GEOLOGY


In south Florida are some "pseudosprings" or false springs, however. These
are old, deep artesian wells, no longer used, whose casings have rusted away,
so that today they appear to be, or are labeled as, artesian springs. The
locations of Florida's pseudosprings are described in some detail in that sec-
tion of the report labeled "Pseudosprings."
The Floridan Aquifer consists of limestone and dolomite older than middle
Miocene age and younger than early Eocene age. Table 4 is a generalized
Tertiary stratigraphic column that shows the vertical position of the Floridan
Aquifer in Florida. The Ocala Group" (table 4) is the principal water-
bearing stratum in much of western peninsular Florida and in much of
western peninsular Florida; in the "Big Bend" and southwest peninsular
areas, the Suwannee and St. Marks Limestones are the principal aquifers;
and in the Jackson-Washington-Holmes County area (Vernon and Puri,
1964) the Marianna Limestone is the principal one. Other formations that
are important parts of the Floridan Aquifer are the Lake City and Avon
Park Limestones of middle Eocene age in western peninsular Florida; and
the Chattahoochee", Chipola, and Hawthorn Formations of early and middle
Miocene age in north and southwest Florida. For a more detailed discussion
of the Floridan Aquifer, see Stringfield (1966, pp. 95-98).
The Hawthorn Formation plays a dual role in that in some areas its lower
part is composed of permeable carbonate beds (aquifer) and the upper part
is composed of impermeable plastics (confining beds). Where present in the
Hawthorn, the clay, marl, and less porous impure limestone of Miocene age
and younger serve an important role as the impervious beds that bound the
upper surface of the Floridan Aquifer and confine the water in the Floridan
Aquifer under pressure.
The quantity of water present in the aquifer depends on the porosity of
the rock, that is, on the volume of the spaces or pores or cracks between the
solid rock particles. Porosity may be categorized as intergranular porosity
(between grains) or as macroporosity, a more gross feature related to solu-
tion or fracturing (cavities, cracks, etc.) of the aquifer rock.


"The name used by the Florida Bureau of Geology to include three forma-
tions, from older to younger: the Inglis Formation, Williston Formation, and
Crystal River Formation. The equivalent terminology used by the U. S. Geo-
logical Survey is Ocala Limestone, which is divided into an upper and a
lower member. The lower member is approximately equivalent to the Inglis
and Williston Formations, whereas the upper member is approximately equiv-
alent to the Crystal River Formation.
bThe U. S. Geological Survey uses Tampa Limestone instead of Chattahoochee
Formation.













BULLETIN NO. 31


After deposition, sediments undergo reduction of initial pore volume
through compaction, which may be followed by induration or lithification of
the sediments by cementation, further reducing the porosity. Most of the
rocks that make up the Floridan Aquifer are poorly indurated so that sub-
stantial primary porosity remains. Some limestone strata within the aquifer
have, however, undergone chemical and physical changes through partial
dolimitization and recrystallization. This alteration generally results in yet
a further decrease in intergranular porosity a condition of secondary
porosity.
So that water can move through the rock, pore spaces, cavities and cracks
must be connected; the rock must have porosity and permeability. An aquifer

that yields large amounts of water to springs (as much as several million
gallons per day) is very porous and permeable. Of the two kinds of porosity
cited earlier, it is macroporosity (the caverns and cavities) on which the
tremendous flow of some of Florida's springs depend. A spring connected to
a cavernous limestone may have a large flow depending on the hydraulic
gradient.
How these caverns were formed is interesting. Limestone, only slightly
soluble in pure water, is easily dissolved in water that contains carbon di-
oxide, because carbon dioxide and water produce carbonic acid. Carbon
dioxide is derived from rain falling through atmosphere and from the soil
in which carbon dioxide is produced by plant respiration and organic de-
composition. Solution of limestone by natural waters in which carbon dioxide
is dissolved is the principal cause of cavities and caverns found in carbonate
rocks.
As with porosity, permeability of a rock is classed either as primary or
secondary. Primary permeability results from the interconnection of the
original pore spaces remaining between the individual grains of the rock
after deposition. The primary permeability of limestone depends on the size
and shape of the rock grains. As most Florida limestones contain a high per-
centage of shells and microfossil tests, their primary permeability is high.
As with porosity, primary permeability is frequently reduced or destroyed
by the processes of dolomitization and recrystallization. Secondary perme-
ability, as in the case of macroporosity, develops from the solution of the
rock by water containing carbon dioxide. The extent to which secondary
permeability has developed usually determines the usefulness of limestone as
an aquifer. Dissolution occurs chiefly along joints, fractures, and bedding
planes, as well as along zones which had sufficient primary permeability to
permit circulation of water. These openings may range from only a slight
increase in the original interstitial openings, through etching of individual
mineral grains, to solution cavities several feet or even several tens of feet
across.
Because solution activity tends to concentrate in zones of the greatest
ground-water circulation, the limestone along fractures, joints, and bedding
planes may be very permeable while surrounding rock may be comparatively
impermeable. Solution along the contact between beds of differing solubility
may result in a zone of cavities and high permeability that is sheet-like in
form. In describing this action in Florida, Vernon says, "The heavy rainfall,
prolific decaying vegetation in Florida and the low evaporation and agitation
in these confined reservoirs cause the artesian waters to be heavily charged
with organic acids and acid-forming gases. The solution of limestone aquifers
in Florida is therefore active and rapid. In fact, the gentle dip of the beds,










BULLETIN NO. 31


the high purity and inherent porosity of the carbonate rocks, the flat sand-
covered divides between relatively few surface streams, the dense vegetation
and humid climate, the relatively high relief and the active circulation of
artesian waters all combine to create in Florida the most favorable conditions
for the active solution of carbonate rock by water" (Ferguson and others,
1947, p. 20).


HYDROLOGY
Some of the rain that falls on Florida and upon the immediately adjacent
parts of adjoining states (fig. 4) collects in lakes or surface-water courses
and flows as rivers and streams to the sea. Some evaporates from free water
surfaces and some transpires from plants all to return to the atmosphere.
Another portion of the rainfall infiltrates the ground to replenish the aquifers
from which virtually all the State's freshwater supply is obtained. It is this -
the infiltrating water- that keeps Florida's springs flowing year after year;
to cease or to be reduced only by drought or if large quantities of water are
pumped from the aquifer in the vicinity of the spring, or if major construc-
tion in the vicinity of the spring disrupts the spring's hydraulic balance.
Water in the ground-water reservoir occurs under either confined or un-
confined conditions. When ground water is not confined under pressure, it is
said to occur under water-table conditions. The water-table aquifers are re-
charged locally and the water table fluctuates rapidly in response to rainfall.
That is, with rainfall the water table rises. The height at which water stands
defines the water table, which is the top of the zone of saturation or the zone
in which all pore spaces are filled with water. The shape of the water table is
usually a subdued replica of the profile of the land surface. Ground water
under the influence of gravity continually moves downgradient, that is, in
the direction that is the downward slope of the water table; and from areas
of recharge to discharge. In the discharge area, where the water table inter-
sects land surface, ground water will discharge at the surface to form a
spring or seep (fig. 1). Likewise, if the water table intersects a stream
channel at an altitude equal to or higher than the water level of the stream,
ground water will flow or seep into the stream channel and add to the flow
of the stream.
Water-table aquifers in Florida are generally made up of Holocenc and
late Tertiary sands exposed at the surface. Some older strata, including lime-
stone beds of the Floridan Aquifer that are near the surface or not covered
by confining beds, also contain water under water-table conditions.
Some ground water moving downgradient in unconfined aquifers enters
aquifers that are or become confined further downgradient by layers of im-

permeable rock. Water confined in such an aquifer is said to be under
artesian pressure, and the aquifer is called an artesian or confined aquifer.
Florida's rainfall and her water-table aquifers are the major source and
avenue for replenishment of the State's artesian water supply.
An artesian aquifer, unlike a water-table aquifer, is completely filled with
water, and because it is overlain by a bed of low permeability, the water is
contained in the aquifer under pressure, to rise above the top of the aquifer
where taped by a well that penetrates the confining bed (see fig. 1). If the
pressure is great enough the water will rise in the well to land surface, to
spill over the top of the casing and form a "flowing well." At such a location,

should a natural passage occur between the aquifer and land surface, a
spring would result.
The Floridan Aquifer is principally an artesian aquifer (fig. 5) composed


(FROM HEALY, 19751

Aquifer.

of limestone and dolomite covered in much of Florida by elastic sedimentary
beds of low permeability. However, in some areas of recharge to the aquifer,
as in the vicinity of the Ocala Uplift (fig. 2), the aquifer is at or near the
surface, and thus is more or less under water-table conditions.
Whereas the porous and permeable sedimentary rocks in the subsurface
of Florida have the capacity to store and transmit large volumes of water,









BUREAU OF GEOLOGY


only part of these sediments contain water of good quality. In the geologic
past, glacial ice has alternately advanced and retreated over the polar regions
due to climatic changes. These shifts in the size of the polar ice caps, and
consequently the quantity of water in the oceans, have caused substantial
fluctuations of sea level; the higher stands inundating most of Florida and
replacing most of the fresh and saline water then in the aquifers with sea-
water. A sufficient interval of time has passed since the last high stand of the
sea to enable fresh water, falling as rain, to infiltrate the aquifers, flushing
and replacing much of the saline water. A substantial part of the Floridan
Aquifer, especially along the coast and in south Florida, however, still con-
tains water whose chloride concentration is in excess of 250 milligrams per
liter, a mixture of freshwater and seawater (fig. 6).


FIGURE 6.- Areas of non-potable water in the upper part of the Floridan
Aquifer.











BULLETIN NO. 31


The Floridan Aquifer is replenished with water in areas where the aquifer
is exposed at the surface or where it is overlain by porous and permeable
material. Where relatively impermeable materials mantle the aquifer, re-
charge may occur through breaches in that mantle, such as sinkholes. Re-
charge areas are where the aquifer is naturally replenished. Cooper (1953,
p. 21) estimated the recharge area of the Floridan Aquifer to be about
13,000 square miles (fig. 7).


FIGURE 7.-Areas of recharge to the Floridan Aquifer











BUREAU OF GEOLOGY


Although the rain that falls on Florida is the source of fresh water, not
all that is available gets into the aquifer. Where the aquifer is full, and there-
fore unable to accept additional water, the rainfall is rejected and leaves the
area as surface runoff to lakes and streams. A substantial quantity of water
that enters the soil is quickly utilized by the vegetative cover through its
root system and is lost by evaporation and transpiration. Where the aquifer
is overlain by sediments of low permeability, downward percolation of water
is retarded and recharge is limited even though the aquifer may not be full.
And when heavy rains occur, the ability of the soil to absorb water may be
exceeded and excess water will flow over the surface to lakes and streams
without the aquifer being filled.
The potentiometric surface can be depicted on a map by a series of con-
tours (or lines) of equal water level. Water in the aquifer moves from high
to low points on the potentiometric surface and the natural direction of move-
ment thus is generally perpendicular to the contours on the potentiometric
surface. Figure 8 represents the potentiometric surface for the Floridan
Aquifer in Florida in May 1974. This map was constructed using water-level
measurements collected from wells and springs throughout the State.
The contours on the map were drawn by connecting points of equal water
level measured in feet above mean sea level. The map is generalized because
of its small size and shows only those major potentiometric features which
maintain a fairly constant relation to one another from year to year. Smaller
local details, such as those caused by changes in pumping patterns or irregu-
larities in rainfall, are not shown.
The highs in the potentiometric surface are generally considered recharge
areas and the lows discharge areas and, of course, there must be discharge
from an aquifer to have a recharge or water movement. Recharge and dis-
charge may occur at many places between the high and low points, however,
wherever geologic conditions permit.
The saddle in the potentiometric surface across the northern part of the
peninsula, includes five first magnitude springs (Rainbow, Silver, Silver
Glen, Alexander, and Blue Springs) and reflects the comparatively low pres-
sure that results from the flow of these and other large springs in this area.
Another potentiometric low is in the Suwannee River valley where the river
has eroded through the confining beds and exposed the artesian aquifer, thus
permitting discharge through springs. Still another prominent discharge area
is between peninsular and panhandle Florida, where a broad low-pressure
trough in the potentiometric surface reflects the discharge from Wakulla and
several other first magnitude springs. The lows, therefore, may be excellent
indicators of the location of numerous or large springs.

FIGURE 8.--Potentiometric surface of the Floridan Aquifer in Florida,
May 1974.

A detailed map of the potentiometric surface in the vicinity of a particular
spring may be used to evaluate the role of the spring in the hydrologic
regime of an area. The catchment area or ground-water basin of a spring
can be outlined by drawing lines along the drainage divide in the potentio-
metric surface. This is illustrated in figure 9 where the catchment area for
Silver Springs is shown on a potentiometric surface map constructed on the
basis of water level measurements from about 130 wells in the Floridan
Aquifer. The flow of Silver Springs is derived from recharge by rainfall
within the bounds of the catchment area. Silver Springs is the largest fresh-
water spring in Florida from the standpoint of long-term average measured
discharge. (See table 2.).








BUREAU OF GEOLOGY


FIGURE 9. Potentiometric surface of the Floridan Aquifee in the Silver
Springs catchment area, May 1968.











BULLETIN NO. 31


Knowing the size of the catchment area for a spring, the average annual
rate of recharge to the aquifer may be calculated if the long-term average
flow of the spring is known, assuming that there is not other discharge from
the aquifer within the catchment area. Hydrologic investigations by Faulkner
(1973, 1976) show that for Silver Springs, the catchment area measured on
a potentiometric surface for May 1968 is about 730 square miles. The
long-term (1932-72) average flow of the spring is 823 cubic feet per second.
Therefore, the average annual recharge to the Floridan Aquifer in the catch-
ment area is 15.3 inches. Stream flow data indicate that average annual sur-
face runoff in about 3 inches; the long-term (1931-60) average annual rain-
fall for the area in 53.2 inches. Therefore, about 35 inches of rainfall on the
average, are lost to the area annually by evaporation and transpiration.
Similar calculations have also been made for Rainbow Springs, another major
first magnitude spring (Faulkner, 1973).
The 3-year record illustrated by figure 10 shows Silver Springs discharge
and ground water levels at nearby Ocala being dependent on rainfall at
Ocala ground-water levels and spring discharge rising and falling together
in response to the variations in Ocala rainfall. Partly because of these re-
lations, changes in springflow are important indicators of current hydrologic
conditions and long-term hydrologic trends of large parts of the aquifer
system.


WATER QUALITY

CHARACTERISTICS OF SPRING WATER
The physical and chemical characteristics of the water discharging from
Florida's springs are indicative of the quality of the ground waters flowing
into the streams of the State. Spring water varies greatly in these character-
istics owing to an almost infinite number of hydrologic and geologic environ-
ments which place particular contraints upon the hydrologic system. The flow
pattern of the water over the land surface, through the rocks and sediments of
the aquifer, and the type of rock determines what type and how much mineral
or organic matter will be present to become dissolved or suspended, and how
much will be lost due to precipitation, drainage, or filtration. Some differ-
ences in water taste, color, and odor are obvious, but our senses cannot
evaluate or detect other, more subtle, differences. We must then rely on
mechanical or electrical devices to make available qualitive and quantitative
identification. These analyses show a wide range in the chemical constituents
and the physical properties or characteristics of spring water.

Many obvious examples may be found to give one a feeling for the extent
of such variations in chemical characteristics of spring water in Florida.
Black Spring in Jackson County is highly colored with organic matter;
Green Cove Springs in Clay County emits a sulfur odor; Salt Spring in
Marion County is, as its name implies, salty; Copper Spring in Dixie County
has deposits of iron around the pool and its run; Indian Springs in Gadsden
County yields water whose dissolved solids concentration is as low as any
water in the natural environment in Florida.
Samples were collected from most of the springs from some for the first
time and many after a lapse of 20 years or more. Few of Florida's springs
show substantial change in the quality of water being discharged as com-
pared to that of 20 or 30 years ago. The water from Florida's springs is
usually of good quality the analyses being typical of water from wells in
the vicinity that tap the Floridan Aquifer. Although few springs are dis-
charging water relatively high in some constituents, none sampled carried
contaminants such as pesticides, herbicides, or abnormal concentrations of
trace elements.
White Springs, formerly known as White Sulphur Springs, yields water
that appears to have freshened over the years. Since first sampled in 1923,
concentrations of several constituents show declines for example, sulfate
from 19 milligrams per liter in 1923 to zero in 1972. The chemist will add
that the data are inadequate to conclude whether the freshening is real or
only apparent, but the people of the White Springs area insist that their
spring has changed water has lost that rotten egg odor that once was so
noticeable!

DEFINITIONS OF CHEMICAL CONSTITUENTS AND
RELATED TERMINOLOGY
The definitions,' means of expressing analytical results, and a simplified
tabulation of the sources, causes, and the significance of individual para-
meters are given to provide background material that will be helpful to the
reader in understanding the chemical and physical analyses that accompany
most of the spring descriptions.
Before the 1968 water year (October 1, 1967 through September 30,
1968), chemical analyses and concentrations of suspended sediment were
reported in parts per million and water temperatures were reported in de-
grees Fahrenheit. In October 1967, the U.S. Geological Survey began re-
porting data for chemical constituents and concentrations of suspended sedi-
ment in milligrams per liter (mg/L) and water temperatures in degrees
Celsius (oC).











BUREAU OF GEOLOGY


Alkalinity. Caused primarily by bicarbonate and hydroxide. Other weak
acid radicals like borate, phosphate, and silicate may contribute to alka-
linity. The significance of alkalinity is the ability of such water to neu-
tralize strong acids. High alkalinity itself is not detrimental but usually
is associated with high pH, hardness, and dissolved solids which can be
detrimental.
Aluminum.- Usually present only in neglible quantities in natural waters
except where the waters have been in contact with the more soluble
rocks of high aluminum content. Acid waters often contain large
amounts of aluminum. High concentrations usually indicate the presence
of acid mine drainage or industrial waste. Aluminum may be trouble-
some in feed waters by forming scale on boiler tubes.
Arsenic.- Found in some ground waters where its source is the natural
arsenic-bearing minerals in wastes from industry and mining activity,
and residues from some insecticides and herbicides. Florida Department
of Environmental Regulation drinking water standards (1975) give a
limit of 50 micrograms per liter (jtg/L) for potable waters. A lethal
dose of arsenic for animals is believed to be about 20 milligrams per
animal pound. Small concentrations in drinking water can accumulate
in man and other animals until lethal dosage is reached.
Bicarbonate and Carbonate. Produced by the reaction of atmospheric car-
bon dioxide with water and are dissolved from carbonate rocks such as
limestone and dolomite. They are significant because they produce al-
kalinity. Bicarbonates of calcium and magnesium decompose in steam
boilers and hot water facilities to precipitate as scale and release cor-
rosive carbon dioxide gas. They combine with calcium and magnesium
to cause carbonate hardness.
Biochemical oxygen demand.-A measure of the quantity of dissolved oxy-
gen necessary for the decomposition of organic material by microorgan-
isms such as bacteria. Biochemical oxygen demand, abbreviated BOD, is
significant in that when it is high, severe oxygen depletion may result,
with eventual harm to the environment. BOD is reported in milligrams
per liter.
Cadmium. Found in wastes from pigment works, textile printing, lead
mines and chemical industries. The results of studies with animals sug-
gest that very small amounts of cadmium can affect the kidneys, heart,
and circulatory systems. Cadmium is toxic to fish in varying concentra-
tions. Drinking water standards of the Florida Department of Environ-
mental Regulation (1975) state that cadmium in excess of 10 pg/L is
cause for rejection of the water supply.











BULLETIN NO. 31


Calcium and Magnesium. Dissolved from practically all soils and rocks,
but especially from limestone, dolomite, and gypsum. Calcium and mag-
nesium are found in large quantities in some brines. Magnesium is
present in large quantities in seawater. Calcium and magnesium cause
most of the hardness and scale-forming properties of water. Waters low
in calcium and magnesium are desired in electroplating, tanning, dyeing,
and in textile manufacturing.
Chloride. Dissolved from rocks and soils; it is also present in sewage and
is found in large amounts in ancient brines, seawater, and industrial
brines. About 300 mg/L chloride in combination with sodium gives a
salty taste to water. Chloride increases the corrosiveness of water. Flor-
ida DER drinking water standards (1975) recommend that chloride
concentration should not exceed 250 mg/L.
Chromium.- Rarely found in waters from natural sources; water can prob-
ably contain only traces of chromium as a cation unless the pH is very
low. When chromium is present in water, it is usually the result of pollu-
tion by industrial wastes such as metal pickling, plating, manufacturing
of paints, dyes, explosives, ceramics, paper, glass, and photography pro-
cessing. Toxicity to aquatic life varies widely with the species, tempera-
ture, pH, and other factors. Florida DER drinking water standards
(1975) limit the maximum concentration of hexavalent chromium to
50 1g/L.
Cobalt.--Occurs in nature in the minerals smaltite (CoAs2) and cobaltite
(CoAsS). Alluvial deposits and soils derived from shales often contain
cobalt in the form of phosphate or sulfate, but other soil types may be
markedly deficient in cobalt in any form (Bear, 1955). Biological activ-
ity may aid in the solution of small amounts of cobalt. It may also be
present in industrial wastes, especially those from manufacture of ceram-
ics, inks, electrical heating units and cobalt pigments. The presence of
cobalt usually suggests pollution. Cobalt has a relatively low toxicity to
man. Fish and aquatic life tolerance varies widely from less than 3.000
t/g/L to more than 10,000 ttg/L. Cobalt is essential to these quantities
for plant growth.
Color. The yellow-to-brown color of some water is usually caused by or-
ganic matter extracted from leaves, roots, and other organic substances.
Objectionable color in water may also result from industrial wastes and
sewage. Color in water is objectionable in food and beverage processing
and many manufacturing processes; it limits light penetration of water,
thus preventing growth of some organisms. Water for domestic and some
industrial uses should be free from perceptible color. Color is expressed











32 BUREAU OF GEOLOGY

in units of the platinum-cobalt scale proposed by Hazen (1892). A unit
of color is produced by one milligram per liter of platinum in the form
of the chloroplatinate ion.
Copper. A fairly common trace constituent of natural water. Small amounts
may be introduced into water by solution of copper and brass water
pipes and other copper-bearing equipment in contact with the water or
from copper salts added to control algae in open reservoirs. Copper salts,
such as sulfate and chloride, are highly soluble in waters with a low pH
but in water of normal alkalinity the salts hydrolyze and copper may be
precipitated. In the normal pH range of natural water containing carbon
dioxide, copper might be precipitated as carbonate. Copper imparts a
disagreeable metallic taste to water. As little as 1,500 ttg/L can usually
be detected, and 5,000 Cjg/L can render the water unpalatable. Copper
is not considered to be a cumulative systemic poison like lead and mer-
cury; most copper ingested is excreted by the body and very little is
retained. The pathological effects of copper are controversial, but it is
believed very unlikely that humans could unknowingly ingest toxic quan-
tities from palatable drinking water. Florida DER (1975) recommends
that copper should not exceed 1,000 /ig/L in drinking and culinary
water. Copper is essential in trace amounts for plant growth but becomes
toxic in large amounts.
Dissolved Oxygen.- Easily dissolves in water from air and from oxygen
given off in the process of photosynthesis by aquatic plants. Dissolved
oxygen increases the palatability of water. The amount necessary to sup-
port fish life varies with species and age, with temperature, and concen-
tration of other constituents in the water. Under average stream condi-
tions, 5 mg/L is usually necessary to maintain a varied fish fauna in
good condition. For many industrial uses, zero dissolved oxygen is de-
sirable to inhibit corrosion.
Dissolved solids. Chiefly the mineral constituents dissolved from weather-
ing or rocks and soils. Waters containing more than 1,000 mg/L of
dissolved solids are unsuitable for many purposes. The U.S. Geological
Survey classifies the degree of salinity of these more mineralized bodies
of water as follows (Swenson and Baldwin, 1965):
Dissolved solids (mg/L) Degree of Salinity
Less than 1,000 .......................... ............................... Nonsaline.
1,000 to 3,000 ............................. .............................. Slightly saline.
3,000 to 10,000 .......................................................... Moderately saline.
10,000 to 35,000 ........................................................ Very saline.










BULLETIN NO. 31


Fluoride. May be present in water in small to minute quantities as a result
of leaching of fluoride bearing rocks and soil. It also may be present in
municipal supplies as a result of fluoridation. Fluoride in drinking water
reduces the incidence of tooth decay when the water is consumed during
the period of enamel calcification. However, it may cause mottling of the
teeth depending on the concentration of fluoride, the age of the child,
amount of drinking water consumed, and susceptibility of the individual.
(Maier, 1950).
Hardness.- In most waters, hardness is due to the calcium and magnesium
content. All of the metallic cations other than the alkali metals also
cause hardiness. Water that is high in calcium-magnesium carbonate
consumes soap before a lather will form and deposits soap curd on sinks
or bathtubs. Hard water forms scale in boilers, water heaters, and pipes.
Hardness equivalent to the bicarbonate and carbonate is called car-
bonate hardiness. Any hardness in excess of this is called non-carbonate
hardness. Waters of hardness up to 60 mg/L are considered soft; 61 to
120 mg/L, moderately hard; 121 to 180 mg/L, hard; more than 180
mg/L, very hard (Durfor and Becker, 1964).
Hydrogen ion concentration. Commonly is expressed in terms of pH, where
pH = -log (H+). Hydrogen ions are derived from ionization of weak
and strong acids. Acid-generating salts and dissolved gases such as S02
and CO2 increase the number of hydrogen ions. Carbonates, bicar-
bonates, hydroxides, phosphates, silicates, and borates reduce the number
of hydrogen ions. Hydrogen ion concentration in terms of pH ranges
between 0 and 14. A pH of 7.0 indicates a solution that has an equal
number of hydrogen and hydroxide ions. A pH higher than 7.0 denotes
a predominance of hydroxide ions; a pH less than 7.0 denotes a pre-
dominance of hydrogen ions. Corrosiveness of water generally increases
with decreasing pH, although excessively alkaline waters may also at-
tack metals.
Iron. Dissolved from many rocks and soils. On exposure to air, normal
basic waters that contain more than 1,000 /xg/L of iron become turbid
with the insoluble reddish ferric compounds produced by oxidation.
Surface water, therefore, seldom contains as much as 1.000 ptg/L of
dissolved iron, although some acid waters carry large quantities of iron
in solution. More iron than about 300 itg/L may stain laundry and
utensils reddish-brown. Water high in iron is objectionable for food
processing, textile processing, beverages, ice manufacture. brewing and
other processes. Florida DER (1975) limits, and for esthetic reasons,
iron and manganese should not exceed 300 Itg/L. Larger quantities
cause unpleasant taste and favor growth of iron bacteria.











BUREAU OF GEOLOGY


Lead. Seldom occurs naturally in surface or ground waters, but industrial
mine and smelter effluents may contain relatively large amounts of lead
which may contaminate a water source. Atmospheric contamination with
lead produced from several types of engine exhausts has considerably
increased the availability of this element for solution in rainfall, result-
ing in lead contamination of water bodies (Hem, 1970). Florida DER
(1975) drinking water standards state that lead shall not exceed 50
/tg/L in drinking and culinary water. Maximum safe concentrations for
animal watering is reported to be 500 ug/L. Toxicity of lead to fish de-
creases with increasing water hardness.
Manganese. -- May be dissolved from some rocks and soils; it is not as com-
mon as iron. Large quantities are often associated with high iron con-
tent and with acid waters. Manganese has the same objectionable fea-
tures as iron; it causes dark brown or black stains. Florida DER
drinking water standards provide that iron and manganese together
should not exceed 300 /g/L.
Micrograms per liter. A unit expressing the concentration of chemical
constituents in solution as weight (micrograms) of solute per unit
volume (liter) of water. Its symbol is xg/L. One thousand micrograms
per liter is equivalent to one milligram per liter.
Milligrams per liter. A unit for expressing the concentration of chemical
constituents in solution. Its symbol is mg/L. Milligrams per liter repre-
sents the weight of solute per unit volume of water.
Mineral constituents (inorganic substances which occur naturally in the
earth) in solution. The analyses listed in this report include only those
mineral constituents that have a practical bearing on water use. The
analyses generally include silica, iron, calcium, magnesium, sodium,
potassium, carbonate, bicarbonate, sulfate, chloride, fluoride, nitrate,
pH, and dissolved solids. Aluminum, manganese, color, specific conduct-
ance, dissolved oxygen, and other dissolved constituents and physical
properties are reported for certain springs. Organic components (al-
though not mineral) may have an influence over the amount of mineral
constituents in solution.
Nickel. -The presence of nickel in water suggests pollution. When present
it is chiefly from metal-plating works, or from manufacturing of ceramic
colors and inks. Federal drinking water standards do not place a limit
on nickel. In the Soviet Union the maximum permissable concentration
is 1,000 ug/L. (Kirkor, 1951).
Ammonia Nitrogen. -Includes nitrogen in the form of NHa and NH4+. It
is found in many waters but usually only in trace amounts although











BULLETIN NO. 31


waters from hot springs may contain high concentrations. Found also in
waters carrying sewage and other organic wastes; presence in surface
or ground water usually indicates organic pollution. Toxicity to fish is
dependent on the pH of the water; 2.5 mg/L ammonia nitrogen can be
harmful in the 7.4 to 8.5 pH range (Ellis and others, 1946). Ammonium
salts are destructive to concrete made from portland cement.
Organic Nitrogen. Originates from amino acids, proteins, and polypep-
tides; derived from living organisms and their life processes and from
wastes and sewage. Presence of organic nitrogen sometimes indicates
pollution; increases nutrient content of water through decomposition and
formation of other nitrogen forms.
Nitrate Nitrogen.-Derived from decaying organic matter, sewage, fertilizers,
and nitrates in soil. Nitrate concentrations much greater than the local
average may suggest pollution. There is evidence that water with more
than about 10 mg/L of nitrate (N) may cause a type of methemoglobi-
nemia in infants which may be fatal and therefore should not be used in
baby feeding (Maxcy, 1950). Nitrate encourages growth of algae and
other organisms which produce undersirable tastes and odors.
Nitrite Nitrogen. Unstable in the presence of oxygen, it is present in only
small amounts in most waters. Found in sewage and other organic
wastes, nitrite is usually an indication of recent organic pollution. Un-
desirable in waters for some dyeing and brewing processes.
Total Kjeldahl Nitrogen. The sum of ammonia nitrogen and organic nitro-
gen. (See ammonia nitrogen, nitrite, nitrate, and organic nitrogen.)
Nutrients. Chemicals necessary to the growth and reproduction of rooted
or floating flowering plants, ferns, algae, fungi, or bacteria.
Pesticides. Chemical compounds used to control the growth of undesirable
plants and animals. Major categories of pesticides include insecticides,
miticides, fungicides, herbicides, and rodenticides. Since the first appli-
cation of DDT as an insecticide in the early 1930's, there have been
almost 60,000 pesticide formulations registered, each containing at least
one of the approximately 800 different basic pesticide compounds
(Goerlitz and Brown, 1972, p. 24). Unless otherwise noted on the
analyses, the pesticides tested for include the insecticides: aldrin, DDD,
DDE, DDT, dieldrin, endrin, heptachlor, heptachlor expoxide, lindane,
chlordane, toxaphene, ethion, trithion, methyl trithion, parathion, methyl
parathion, malathion, and diazinon; and the herbicides: 2, 4-D, silvex,
and 2, 4, 5-T.
Picocurie. One millionth of the amount of radioactivity represented by a
microcurie, which is the quantity of radiation represented by one mil-










BUREAU OF GEOLOGY


lionth of a gram of radium-226. Its symbol is pCi. A picocurie of radium
results in 2.22 disintegrations per minute.
Polychlorinated biphenyls (PCBs).- A class of compounds produced by the
chlorination of biphenyls. PCBs are soluble in water, lipids, oils and
organic solvents, and resistant to heat and biological degradation. They
are relatively nonflammable, have useful heat exchange and dielectric
properties and are used in the electrical industry in capacitors and trans-
formers. Can be harmful to fresh water and marine aquatic life and
their consumers, and to humans. (EPA 1976, p. 193.)
Radioisotopes. Isotope forms of an element that exhibit radioactivity. Iso-
topes are varieties of a chemical element that differ in atomic weight,
but are very nearly alike in chemical properties. The difference arises
because the atoms of the isotopes forms of an element differ in the num-
ber of neutrons in the nucleus. For example: ordinary chlorine, whose
atomic weight is 35.453, is a mixture of isotopes having atomic weights
35 and 37. Many of the elements similarly exist as mixtures of isotopes,
and a great many new isotopes have been produced in the operation of
nuclear devices such as the cyclotron (Rose, 1966). There are 275 iso-
topes of the 81 stable elements in addition to over 800 radioactive
isotopes.
Specific Conductance. A measure of the ability of a water to conduct an
electrical current; it is expressed in micromhos per centimeter at 250C.
Conductance is related to the type and concentration of ions in solution
and can be used for approximating the dissolved-solids content of the
water.
Strontium. Occurs in water where strontium minerals, such as celestite
and strontianite, are present. Is found in seawater and many brines.
Naturally occurring strontium is similar chemically to calcium and adds
to the hardness of water. Radioactive isotopes of strontium, as from
nuclear bomb fallout, can be harmful. These isotopes can be detected by
radiometric measurements.
Sulfate.- Dissolved from rocks and soils containing gypsum, iron sulfides,
and other sulfur compounds. Sulfate is usually present in mine waters
and some industrial waters. Sulfate in water containing calcium forms a
hard scale in steam boilers; and in large amounts, sulfate in combination
with other ions gives a bitter taste to water. Some calcium sulfate is
considered beneficial in the brewing process. Florida DER drinking
water standards state that the sulfate concentration should not exceed
250 mg/L.
Temperature. Sources of heat are solar energy, heat from earth's core and
thermal pollution from waste outfalls. The temperature of water affects

its usefulness for many purposes. Water of uniformly low temperature is
desired for most uses. Temperature of water in shallow wells shows
some seasonal fluctuations; wells of moderate depths usually yield water
which is near the mean annual air temperature of the area. In very deep
wells, the water temperature generally increases on the average about

Total Organic Carbon.- A measure of the organically related carbonaceous
content of water. It includes all natural and manmade organic com-
pounds that are combustible at a temperature of 9500C.

Turbitity.- Caused by colloidal suspension of sediment, precipitates, and
other small particles. Turbitity should be less than 5 Jackson turbidity
units (JTU) for domestic use. Turbidity interferes with light penetra-
tion, limits growth of organisms, and if high, is lethal to some life forms.
Zinc.- Dissolved from some rocks and soils; it is found in high concentra-
tions in mine waters that have a low pH. Zinc may be derived from
zinc plated or galvanized metal products; it is used in many commercial
products, and industrial wastes may contain large amounts. Small
amounts of zinc are toxic to aquatic plants and animals. Zinc may have
such a toxic action on the purifying bacterial flora of streams that seri-
ous sewage pollution problems result. Florida DER drinking water
standard limit zinc concentrations to 5,000 jLg/L.

DISTRIBUTION OF FLORIDA SPRINGS
The distribution of springs within the state of Florida is not entirely
random. 'Ae discussions on geology and hydrology show that certain environ-
mental factors affect the potential for spring development. Where the primary
physical control is a downcutting river or a local karst topographic feature,
the effect may be a regional concentration of springs as in the Suwannee
River basin, or an isolated spring as in Sarasota County.
Of the 300 springs listed in this report, most are the result of regional in-
fluences, with only a few the result of local influence. The few water-table
"seeps" or "filtration" springs, are mainly in northern Florida. Others are
unusual in that they are "deep source" springs.
In Florida there are 27 springs of first magnitude. They are listed in
table 2 and their locations are shown in figure 11. All are described in detail.
Each of these 27 springs, or groups of springs, is discharging water from the
Floridan Aquifer at an average rate exceeding 100 cubic feet per second.
They have a total average flow of 9,600 cubic feet per second or about 80
percent of the 12,000 cubic feet per second estimated discharge of all of
Florida's springs. These first magnitude springs include several that are na-
tionally or even internationally known, such as Rainbow, Weeki Wachee, and
Wakulla Springs, which are in Marion, Hernando, and Wakulla counties,
respectively. Other first magnitude springs are unknown to even nearby resi-
dents; examples are Alapaha Rise and St. Marks Spring, which are in
Hamilton and Leon counties, respectively.

THE HYDROLOGIC SUBREGIONS
Florida is divided into eight hydrologic subregions on the basis of surface
drainage systems. These subregions are aggregates of smaller hydrologic
units (U.S. Water Resources Council, 1974; Conover and Leach 1975).
The following text and figures identify the springs and spring groups by
name, number, and county for each of the hydrologic subregions of the State
and for those springs known through 1976. The recent establishment of three
new Water Management Districts in Florida has increased field exploration
by hydrologists and geologists interested in water resources. As a result, many
springs previously unreported and known to only a few nearby residents have
been located and described. Alapaha Rise in Hamilton County is an example
of such a spring. Increased scientific investigation and the expansion of our
population into the wooded and swampy areas of north Florida will bring
identification of other "new" springs.

ALTAMAHA -ST. MARYS RIVERS SUBREGION
This subregion in the northeastern part of the state (fig. 12) encompasses
about 1,380 square miles in the Coastal Lowlands and Central Highlands.
Su-No-Wa Spring in Nassau County, the only spring reported in the sub-
region, is a seep resulting from local hydrologic conditions.

ST. JOHNS SUBREGION
From Duval County in the north to Indian River County in the south, this
subregion covers 11,310 square miles in the Coastal Lowlands and eastern
Central Highlands (fig. 12). It is known to have 51 springs including Silver
Springs, considered to be Florida's largest freshwater spring owing to its
long-term measured average flow. The springs are concentrated in Alachua,
Clay, Lake, Marion, Orange, Putnam, Seminole, and Volusia counties. All
are situated around the central part of the subregion. The area is transected
by the Deland, Crescent City, and Mount Dora Ridges, the Marion Uplands,
and the St. Johns River Offset (Puri and Vernon, 1964, fig. 6). Superim-
posed upon these features is a karst topography to which most of these
springs owe their occurrence.

SOUTHERN FLORIDA SUBREGION
This is the largest hydrologic subregion'of the state, encompassing 18,212
square miles or over one third of the Florida peninsula. It is generally flat
and lies almost entirely within the Coastal Lowlands. Although several springs
were known in the early years of the development of the Miami area, none

of them now flow (Ferguson and others, 1974). However, six pseudo or
false springs are included in this report because they are commonly identified
as springs. The pseudosprings are artesian wells; and they are briefly dis-
cussed in the section entitled "Florida's Pseudosprings."

PEACE, WITHLACOOCHEE, HILLSBOROUGH RIVERS AND
WESTERN COASTAL AREA HYDROLOGIC SUBREGION
Consisting of the west-central part of Florida's peninsula (fig. 13), this
hydrologic subregion accounts for 9,811 square miles in the Coastal Low-
lands and Central Higlhands. It is an area of low plains, of hilly areas in the
eastern extremes, and of karst features in the central and northern parts.
About a dozen of the 61 known springs are karst related and situated along
the coast in Citrus, Hernando, and Pasco counties, whereas most of the
others, in Citrus, Marion, Sumter, Pasco, and Hillsborough counties are as-
sociated with downcutting river systems. Two springs in south Sarasota
County are deep warm water springs.

SUWANNEE AND AUCILLA RIVERS
HYDROLOGIC SUBREGION
Of the 13,720 square miles of this Subregion, 7,832 square miles are in
Florida, mainly in the Coastal Lowlands but including some of the northern
section in the Northern Highlands (fig. 14), the remainder are in Georgia.
Of the 115 known springs in this area, most are associated with the down-
cutting Suwannee and Santa Fe Rivers in Hamilton, Madison, Suwannee,
Lafayette, Gilchrist, Dixie, Levy, Columbia, and Alachua counties. In or
near the channels of the Suwannee and Santa Fe Rivers many other springs
are believed to occur.

OCHLOCKONEE RIVER HYDROLOGIC SUBREGION
Of the 2,324 square miles of this Subregion in Florida, about half lies in
the Gulf Coastal Lowlands and half is in the Tallahassee Hills (fig. 15.).
The Subregion includes all or part of Wakulla, Leon, Franklin, Liberty,
Gadsden, and Jefferson counties. There are 27 reported springs or spring
groups, including Spring Creek, most of them concentrated in Leon and
Wakulla counties, Spring Creek has the largest known spring discharge of
fresh water or saline water in Florida.

APALACHICOLA, CHATTAHOOCHEE, AND FLINT RIVER
HYDROLOGIC SUBREGION
About 16 percent, or 3,081 square miles, of the Apalachicola, Chattahoo-
chee, and Flint River Subregion is in Florida (fig. 15). About 19 springs

CHOCTAWHATCHEE, YELLOW, AND ESCAMBIA RIVER
HYDROLOGIC SUBREGION


The western panhandle of Florida includes 6,491 square miles of the
14,740 square miles of the Subregion (fig. 15). Florida has 18 springs

associated with the Western Highlands, Choctawhatchee River valley, and the
Escambia valley. Most of the springs are the result of river erosion and arc

in Washington, Holmes, Bay. and Walton counties. There probably arc
many more small springs and seeps than the few known in Walton, Santa

Rosa. and Escambia counties.

SPRING DESCRIPTIONS
SPRING NAMES
There is considerable confusion about the names of many of Florida's
springs. Any number of these natural ground-water discharge sites have but
a single vent and yet are popularly identified in the plural "Springs". Others
have been known by several names; they may have had place names or have
been named after individuals such as their owners. Blue Spring in Volusia
County is in Blue Springs State Recreation Area; and U.S. Geological Sur-
vey records dating back to 1932 have identified it as "Blue Springs near
Orange City." Ferguson (1947, p. 163) identified the same spring as Blue
Spring near Orange City.
The policy that the authors tried to follow in the use of spring names was:
(1) to delete the place modifiers, "near Orange City" for example, from the
name "Blue Spring"; and (2) to follow established published usage when-
ever feasible. For the latter, the primary reference was Bulletin 31 of the
Florida Geological Survey, prepared by Ferguson and others; the secondary
reference was the recent U.S. Geological Survey 71V-minute topographic
quadrangle maps; and third, other publications. Local usage followed. If a
choice had to be made between the singular and plural forms of "spring,"
the physical situation was the determining factor.

SPRINGFLOW
Springflow is indicative of the status of Florida's water resources. High
spring and streamflows reflect high water levels; and low flows, or the lack
of flow from major springs, indicates declining potentiometric levels in the
principal artesian aquifer of the state. An example of the latter condition is
Polk County's Kissingen Spring. Most of Florida's streams depend on the
water discharged from springs for a significant part of their flow; the
Wacissa and Suwannee Rivers are but two of many such streams. The
periodic statewide measurement of springflow, streamflow, and ground-water
levels is, therefore, necessary if man is to be knowledgeable about the water
resources available to him.
Spring and streamflow are normally expressed in cubic feet per second, in
million of gallons per day, or in gallons per minute if the volume being
measured or reported is small. A rate of flow (discharge) of 1 cubic foot
per second represents a volume of 1 cubic foot of water passing a given
point during 1 second. Table 6 lists the equivalents useful in converting be-
tween the more common hydraulic units.
Springflows are usually measured in the first straight uniform reach of the

METHODS OF FLOW MEASUREMENT

spring run or stream downstream from the spring. If the quantity of water
flowing from the spring is small, in the range of 1 cubic foot per second and
is discharging through a pipe, a volumetric measurement may be made. An
example is Steinhatchce Spring in Lafayette County. This is done by meas-
uring the time required for the discharging water to fill a container of
known capacity.
A velocity-area method is the most common means of determining dis-
charge in an open channel. This method uses a current meter to determine
the water velocity at a number of points across a channel. For detailed in-
formation on all stream-gaging procedures see Corbett and others, 1962.
Under flood or very high streamflow conditions, external pressure on a
spring may exceed internal pressure thus causing a reversal of its flow.
Falmouth Spring, in Suwannee County, is one of the several springs known
to be so affected but the only one where a reverse flow has been measured.
In reporting the flow of individual springs, the authors cited such unusual
circumstances. Otherwise, the range and average flow were given if all meas-
urements could not be shown.

SPRING-WATER SAMPLING

The methods of collection and analysis of the more recent water samples
are described by Brown, Skougstad, and Fishman (1970). The methods that
were used before 1970 in collecting samples are described by Rainwater and










BUREAU OF GEOLOGY


Thatcher (1960). All water samples were collected from the springs as close
as possible to their orifices, vents, seepage zones, or other points of spring
discharge in order to minimize the effects of contact with surface materials
or the atmosphere.
Sampling of the water from first magnitude springs was more extensive
than from the smaller springs and generally the analyses are more compre-
hensive. For example, many of the samples were analyzed for trace elements,
nutrients, insecticides, herbicides, and polychlorinated biphenyls. A list of
those pesticides generally tested for is included in the section on water
quality.

SPRING IDENTIFICATION NUMBERS
Spring-discharge and water-quality data collection sites (Table 7) have
been identified by either of two systems: a 15-digit identifier or an 8-digit
downstream order number. The former system requires explanation because
it may also be the geographical location of a station the numbers consist
of the latitude and longitude coordinates to the nearest second, plus "00" or
a 2-digit sequential number such as "01." For example, the first part of the
number 275134081522001 indicates that the data collection site is in the
1-second quadrangle bounded by latitude 27051'34" on the south and the
last part indicates that the quadrangle is bounded by longitude 81052'20"
on the east. The "01" remaining is a sequential number and indicates there
may be other data collection sites in that 1-second quadrangle. The geogra-
phical significance may become a little more clear by reference to figure 16,
for the 15-digit number cited above.
Once the 8- or 15-digit numbers are assigned, they are not subject to
change. Even though the latitude and longitude coordinates may change
owing to more accurate mapping, or to a change in the location of the data
collection site, the station identification number remains as originally
selected.
All discharge and water-quality data collected for the springs are available
from the U.S. Geological Survey. The identifier numbers just described are
important because all the information is filled by these numbers in the Sur-
vey's data storage bank. A few springs lack identifying numbers because of
poor location information. Others may have two or more numbers; the second
assigned without knowledge of the first. Troy Spring in Lafayette is an ex-
ample of a data point that has two numbers: Springflow data are filed under
the number 02320050, but physical details of the spring and its water-quality
data are filed under the 15-digit identifier. So, the use of both numbers is
necessary to retrieve all the information for that spring.

DESCRIPTIONS OF INDIVIDUAL SPRINGS
This section contains detailed information about Florida's springs. Some
of the springs are known to but a few people; others are well known and
have been scientifically observed for years. Uniformity of spring descriptions
was necessary to obtain the brevity and consistency that would permit in-
clusion of most spring descriptions in a single book. Therefore, the descrip-
tions were standardized for presentation of spring location, discharge, and

quality-of-water data. Physical descriptions and utilization data are as com-
plete as information permits. Some photographs, interesting historical items,
and other information of a special nature were made part of the descriptive
material.

GLEN SPRINGS
(Text Figure 1)
Location. SE1SE/SW1 sec. 30, T. 9 S., R. 20 E. (lat. 29040'27" N.,
long. 82020'50" W.). Glen Springs is in the northwest quadrant of the
city of Gainesville. On U.S. Hwy 441 drive north 1.5 mi from inter-
section with State Hwy 26, turn left (west) onto State Hwy 232A for
0.5 mi, turn left (south) into the Elks Club parking lot; the springs are
in the adjacent wooded ravine (fig. 12).
Description. Situated in the upper end of a wooded ravine on the edge
of a plateau, the springs flow southeastward and are tributary to Hog-
town Creek in the northwest end of the Oklawaha River basin. The

elongate, irregularly-shaped head pool is in limestone bedrock. The head
pool is about 20 ft long and 10 ft wide and is enclosed by a concrete
wall. This concrete enclosure is convex on its upstream end and flat on
its downstream end. A control gate in the downstream end regulates
flow to the first of two in-line concrete swimming pools built into the
ravine immediately downstream from the springs and behind a club-
house. Flow emanates from several small submerged solution channels
in the rocks in the bottom of the pool. From the pool, water flows suc-
cessively from one swimming pool to the next, thence down the ravine
to Hogtown Creek.

HORNSBY SPRING
(Text Figure 2)
Location. NENEISE% sec. 27, T. 7 S., R. 17 E. (lat. 29050'59" N.,
long. 82035'36"W.). The spring is about 1.5 mi N. of the town of
High Springs. Drive northwest on U.S. Hwy 441 from the junction
with State Hwy 236 for about 1.6 mi, turn right (east) onto the road
going to Camp Kuluqua, continue 0.9 mi to the camp. The spring is
inside the camp grounds about 300 ft NW. of the camp entrance (fig.
14).
Description.- The spring is in a low area surrounded by cypress trees. It
forms an elliptical pool about 125 ft wide and 185 ft long oriented
westward, and narrowing at its west end to a run in which flow is west-

northwest 0.8 mi to the Santa Fe River. The pool is partly enclosed on
the east and north by a rock and concrete retaining wall 2 to 3 ft high.
A diving platform and board extend out from the east edge of the pool.
The spring flow is apparently from the east, from a cavern opening or
openings under a submerged limestone ledge a short distance out from
the diving board. Depth of water over the ledge, as sounded from the
diving board on February 25, 1972 was 16 ft. On that date no boil was
evident in the pool and the water was tinted brown. It was otherwise
clean and clear and its temperature was 22.50C. (720F.). The spring
is subject to backwater from the Santa Fe River. The buildings at the
camp occupy high ground bordering the spring on the east and north.
Discharge. April 19, 1972 250 ftW/s
April 25, 1975 76
Utilization. Used as a swimming and recreational facility by Camp
Kulaqua, privately owned and operated by a religious organization.
Water Quality.- Analyses by U.S. Geological Survey. Units are in milli-
grams per liter unless otherwise indicated.

MAGNESIA SPRING
(Text Figure 3)
Location. SE'NE/NW sec. 31, T. 10 S., R. 22 E. (lat. 29034'58" N.,
long. 82009'00"W.). The spring is about 4 mi W. of the town of
Hawthorne. Drive west from old U.S. Hwy 301 on State Hwy 20A for
3.8 mi, turn left onto graded road for 0.3 mi to gate, continue 0.1 mi
to the spring pool. The spring also may be reached by State Hwy 20A
from Grove Park, 1.2 mi NW. of the spring (fig. 12).
Description. The spring lies at the base of the sandy pine wooded hills on
the east side of the Lochloosa Creek valley. The spring discharges to
Lochloosa Creek, which flows into Lochloosa Lake, and is in the Okla-
waha River subbasin of the St. Johns River basin. The spring forms a
60-by 75-ft oval-shaped pool enclosed by a concrete wall. The spring
reportedly has a clay and sand bottom with two holes formerly about
16 and 30 ft deep. About 90 percent of the flow is believed to come
from the deeper of the two holes, which is about 20 ft in diameter at
its top and is in the north part of the pool. In 1946 the pool reportedly
had been sounded with an iron pipe to a depth of 30 ft. The pipe was
pushed downward through soft sand in the bottom an additional 30 ft.
When interviewed in February 1972, a former owner of the spring
reported that the pipe penetrated only a 4- or 5-ft thickness of soft sand
before it encountered clay and scattered hard rocks. The former owner
also said that in 1950 a large piece of the clay wall of the hole slumped
and blocked much of the flow and reduced the depth of the hole. The
temperature of the water on April 16, 1946, taken 1 ft below the surface

1950's, the water was piped to a swimming pool just east of the spring.
The water is now allowed to flow from a surface outlet on the north
end of the spring pool into an open ditch and thence eastward and
southward around the swimming pool to Lochloosa Creek. The swim-
ming pool is now supplied with water from five 4-in. flowing artesian
wells ranging in depth from 75 to about 120 ft.

POE SPRINGS
(Text Figure 4)
Location. SW1/NW/4NE/4 sec. 6, T. 8 S., R. 17 E. (lat. 29049'33" N.,
long. 82038'58" W.). Poe Springs is about 3 mi W. of the town of High
Springs. Drive southwest on U.S. Hwy 41 and State Hwy 236 from the
junction with U.S. Hwy 441 for 0.8 mi, take State Hwy 236 to the right
(northwest) about 2.5 mi, turn right (north) onto graded unpaved road
bending to the west for 0.6 mi; the springs are directly ahead (fig. 14).
Description. Poe Springs form a circular pool about 90 ft in diameter on
the wooded south bank of the Santa Fe River. The pool is connected to
the river by a northward flowing run about 175 ft long and 40 ft wide.
On February 25, 1972, a large boil with two or three minor boils near-

by was observed in the central part of the pool where most of the flow
issues from a horizontal cavern. The pool reportedly was about 36 ft
deep 50 years earlier, but has apparently filled in considerably with
sand and debris. The measured depth of the pool in 1946 was 16.6 ft
and in 1972 the depth was estimated to be 16 to 17 ft. Inflow to the
pool, in adidtion to that from the vicinity of the boils, comes from
small springs and seeps in the swampy area immediately adjacent to the
main spring. In the mid-1940's the springs formed the center of a com-
mercial recreation site used primarily for swimming and picnicking.
The pool was enclosed on the south and west by a board and sheet
metal wall and the site was complete with bathhouses, refreshment stand
and picnic facilities. Except for a few weathered pilings which had sup-
ported the bathhouses on the west side of the pool, no evidence of the
development remains. The spring had reverted to an essentially natural
appearance.

BAY COUNTY
GAINER SPRINGS
Formerly called Blue Springs, Gainer Springs consists of three major and
at least two minor springs. They are not individually named but have been
designated Spring 1A, 1B, 1C, 2, 3, and 4.
Location.- SWI/ sec. 4, T. 1 S., R. 13 W. (about lat. 30025'35" N., long.
85032'53" W.). Drive 2.3 mi N. from Bennett, at intersection of State
Hwy 388 with State Hwy 167, turn west onto winding sand road; about
1 mi to the springs that are along both sides of Econfina Creek (fig. 15).
Description. The area surrounding the springs is covered with a dense
growth of scrub pine and associated vegetation. To the west, on the
opposite side of Econfina Creek, the land rises 80 to 90 ft to a woody
knoll, and to the east the land slopes gently up 10 to 20 ft above the
water surface. Some swamplike growth occurs along the banks of the
creek and spring runs, but generally the area is heavily forested.
Gainer Springs No. 1 is north on the sand road from the powerline
about 0.3 mi to the head of run trending northeast. (See fig. 17). Lat.
30025'40" N., long. 85o32'50" W.
The spring pool farthest to the northeast is No. 1A .It has a diameter
of about 20 ft, and a maximum depth of 6 ft at the vent opening which
is about 1 ft wide. The circular pool is surrounded with dense swamp-
like vegetation that covers it like a canopy. The run exits to the south-
west and reaches a maximum width of about 40 ft just before merging
with Econfina Creek.
Spring No. 1B is about 100 ft downstream of Spring No. 1A, in a de-
pression about 12 ft deep in the run of No. 1A. It does not have a pool.
Spring No. 1C flows into the run from the southeast about 300 ft
farther downstream. The pool has a diameter of about 25 ft and a
maximum depth of 13 ft. An 8 ft diameter vent is in the exposed lime-

stone rock in the bottom of the pool. Bottom sediment is in a state of
constant agitation due to the flow from the vent.
The combined flow from the three springs enters Econfina Creek about
800 ft downstream from No. 1A. During its course, the run varies in
