BULLETIN OF SOUTHWEST FLORIDA WATER MANAGEMENT DISTRICT (REGULATORY
Vol. 2, No. 13 S. Melodie Oleson January, 1972
PUBLIC HEARING ON ORDER TO CITY OF ST. PETERSBURG
The public hearing which was begun on December 8, 1971 was continued
on January 12, 1972 at 9:30 a.m. in the Southwest Florida Water Management
District headquarters. The purpose of the hearing was to provide an
opportunity for all concerned parties to present testimony to the Regulatory
Board regarding an order to be issued to the City of St. Petersburg, which
would regulate the city's withdrawal of groundwater from their well fields.
An amended staff proposal was presented to the Board, reflecting areas which
the staff felt i' would be advantageous to alter. These included: (1) allowing
a review of the order oftener than the previously suggested 6 months if
deemed necessary by the Board; (2) allowing a weekly average to be
developed for each observation well instead of forcing an instanteous-
violation situation in which the water level might be below the regulatory
level for only a few minutes; (3) changing from the "Dundee" observation
well to the "Jackson 26-A" observation well to eliminate the possibility of
irrigation pumpage in the vicinity affecting the water level in the observation
well; (4) requiring that the deep observation well in the new Pasco field be
constructed within 4 months of the effective date of the order to allow the
District to use the data from this well, in developing regulatory criteria
for the Pasco field; (5) changing the effective data for the order to allow
for a specific definition of "operational" as applied to the field and to allow
enough time for the city to finish construction after the current legal problems
with Hillsborough County are settled.
SThe major testimony presented after submission of the amended staff proposed
was that of the City of St. Petersburg's attorney, Mr. Carl Linn and the
city's consultant, Mr. M. L. Brashears. Mr. Linn stated that in view of the
spirit of cooperation which had been displayed in the interim since the
first portion of hearing, he felt that the city would "swallow the pill" although
agreeing that the pill had been sugar coated. According to Mr. Linn, one of
the city's major concerns is that they are not the only one to be regulated,
but rather the first in a series of large water-user.
Mr. Brashears pointed out that the order as submitted would limit the
production from the two presently-operating fields to about 15 m. g. d. each,
or a total production figure smaller than the maximum demand placed on
the system in 1971. It must be remembered, however, that the order will
not be in effect before the Pasco well field becomes operational and therefore
capable of making up the difference between the demand and the allowable
production from the Section 21 and Cosme-Odessa well fields.
Also entering testimony were representatives of Hillsborough County and the
Keystone Civic Club.
The hearing was adjourned before noon on the 12th and the Board will consider
all the testimony presented and make its decision in 30-60 days. A transcript
of the proceedings will be available at the District headquarters for anyone
wishing to read it.

SWFWMD CONTINUES AERIAL MAPPING PROGRAM
Previously reported were 4 projects involving some 300 square miles
of aerial mapping with contours. These projects have been completed
and are now being used for their intended purpose. In particular,
this purpose is that of being the indispensable basic data for water
management study and planning. In addition, this mapping is
available to other governmental agencies on a "no-charge" basis
and is available to all others on a $25. 00 per sheet basis. Projects
referred to above:
1. W. Pasco County
2. Pinellas-Anclote Basin -
3. NW Hillsborough Basin
4. Haines Creek (Oklawaha Basin)
Aerial mapping projects more recently either (1) completed, (2) now
under contract or (3) scheduled for contract negotiation in the immediate
future are as follows:
Lake Panasoffkee Outlet River This project includes aerial
photography of a 4, 000' wide strip of land centered on the outlet
river and extending from Lake Panasoffkee west shore to the
Withlacoochee River. The horizontal scale is 1" = 2001'. Contour
lines at 421 and 44' above mean sea level are shown.
Now Under Contract
Alafia River and Brandon Ar'ea This mapping project includes
approximately 43.5 square miles of the Alafia River flood plain
together with some 42 square miles of flood prone lands in the
general area of the City of Brandon. The horizontal scale will be
i" = 200' and contours will be shown at a 1' interval.
Lakes Mattie and Van Area This mapping project covers approximately
12 square miles of flood prone lands in the area, between Lakes Mattie
and Van in Polk County. A horizontal scale of I" = 200' will be used.
Contours will be at a 1' interval below elevation 140' mean sea level
and at a 5' interval above elevation 140' mean sea level.
BigCypress Swamp Area This mapping project covers approximately
48 square mile s of food prone lands within the Big Cypress Swamp
area of the Hillsborough River Basin. The area is presently under
consideration for two incompatible uses. These uses are (1) flood water
retention area and (2) real estate housing development. The horizontal
scale of the mapping will be 1" = 200' and 1' contours will be shown.
Peace River, Arcadia to DeSoto County South Line This aerial
m-apping-pro'jec-tco-vers approximately 35 square miles of the Peace
River flood plain in DeSoto County. The mapping horizontal scale
will be 1" = 200'. Contours at a 1' interval will be shown.
Withlacoochee River, Dunnellon to State Road _00 and Blue Run,
Dunnellon to Rainbow Springs This mapping project covers
approximately 19.5 square miles of the Withlacoochee River and the
Blue Run flood plains. The mapping horizontal scale will be 1" = 200'.
Contours will be shown at a 1' interval.
It is anticipated that an active aerial mapping program will be a
continuing requirement of SWFWMD. The problems of water management
can only be solved after the basic engineering data is made available
for the required studies and designs. Contoured aerial mapping is the
all important first step of data acquisition.

Within the cone of depression of the pumped well field, the falling
water table empties the pores in the aquifer above the receding water
table thus making available easily reachable empty space capable of
accepting great volumes of recharge water. For example, in a well
field area where the water table has fallen an average of 10 feet over
10 square miles, and where the effective porosity of the dewatered
part of the aquifer is 25 per cent, it would require 5. 2 billion gallons
of recharge water to fill the emptied pores again. _The easiest way
to do this, and the quickest, would be by means of recharge channels
constructed over the area underlain by the cone of depression, and
channeled to flood-detention areas for the pickup of waters that,
if not recharged to the well field, normally would be rushed off
to the bay or the Gulf so as to prevent flooding of valuable downstream
properties. Such waters could be either high-grade reclaimed
sewage effluent such as the City of Tampa's planned treatment plant
will produce, or rain water from storms over the areas.
Such easily rechargeable space would have the capacity for accepting
all the water that a hurricane-type storm might dump during a 10"
rainfall over a 30 square-mile catchment area, or all of Tampa's treated
sewage effluent could be either sprayed over the catchment area or
spread there by recharge channeling.
S In or District the distribution of rainfall is very spotty and often
intense; such intense storms as that mentioned above are not uncommon.
Even during drought periods streams are often swollen by waters of
flash floods resulting from intense thunder storms. Such waters could
easily be diverted to catchment or detention areas and thence into
well-field recharge channels to restore a level of saturation consistent
with nature's balance.
The effectiveness of such an activity would be dependent upon the
amount of flood water available,. the characteristics of the geologic
and hydrologic controls, and the design of the system, including a
suitable catchment or flood-detention area. Currently, plenty of
such sites exist but are generally in private ownership and include
mostly wet lands with cypress heads redominating. Purchases or
easements for the needed sites e -be obtained as soon as possible.
Regarding the water, one T LdLnt even need a big hurricane flood to
o alot of recharging. V several one to three-inch storms
per year, and just one one-inch storm over a 30 square mile catchment
area would furnish Aabout 500 million gallons of readily available
recharge water, whereas a two-inch storm would give i approximately
a billion gallons. Even if evapotranspiration losses took half of the
rainfall before it could be recharged into the well-field aquifer, a one-
inch storm would provide 250 million gallons of recharge water and
a two-inch storm would provide= 500 million. The prospect is enticing
to yepras water managers and hope soon to apply this idea to some
of the large well fields existing in the District, working perhaps, in
concert with the Cities of Tampa and St. Petersburg and the Counties
of Hillsborough and Pasco at the Section 21, the Cosme-Odessa and the
new Pasco fields, and also with Pinellas County at their Eldridge-Wilde
The idea appears to offer a very attractive and effective method of
restoring the natural balance while at the same time stretching J /c
water crop and thus allowing a larger-scale development of our water

An appellate court in Missouri has reserved judgement on a suit brought by
property owners from whose lands a Missouri municipality planned to
pump 11. 5 million gallons of water per day. The court ruled that the
"reasonable use" rule should be followed; that is, no one may withdraw
percolating water and transport it for sale or other use, if the withdrawal
results in injury to an adjoining land owner or impairment of his supply.
The. court did not rule on the landowner's claim, but simply stated its belief
in the applicability of the reasonable use rule. The case will be tried, on that

31 The National Oceanic and Atmospheric Administration reports that the
Florida cloud-seeding experiment conducted in 1971 was a "resounding
success" although the target area had to be moved to prevent the destruction
of a tomato crop. Drought conditions are not conducive to seeding experiments
but it was determined that an additional 180, 000 acre-ft. of rain valued at
about $5 million were produced.

/--/ Long periods of drought will causheeven minor overdevelopment of the
( [ water resources to have the cumulative effect of excessively lowering
"the levels of storage in the aquifer s A very promising method of
counteracting this condition, currently under investigation by the staff
of this District, is water spreading through seepage from a shallow-ditch
distribution system in areas of major stress on the aquifer that has
been caused by large-scale pumping from major well fields.
When water is pumped from a major well field over a long enough
period of time, even though the water is taken from the aquifer
at depth, the effects are felt most noticeably and quickly at the water
table. A "cone-of-depression" develops, deepest in or near the center
of the well field and sloping upward and outward until enough water is
drawn into the cone from the overlying andsurrounding lands to stop
its spreading any further. Such cones in ^a- District may be up to
20 feet deep in the center, as much as 10 feet deep a mile away, and
may create discernible drawdowns as much as 10 miles away.
