SELECTED FLOWCIIARACTERISTICS OF
FLORIDA STREAMS AND CANALS
Summaries of Flow Duration and of Low and
High Flows at Gaging Stations
by
Richard C. Heath and E. Turner Wimberly
ABSTRACT
Tables of flow duration, lowest mean discharge, and highest mean discharge
for selected consecutive periods within each year through September 30, 1965,
at 254 stream-gaging stations on Florida streams are presented. These tables
summarize daily streamflow records needed to define flow characteristics at
stream-gaging sites. The content of each of the three summary tables is
described, and techniques for preparing flow-duration curves, and low-flow and
high-flow frequency curves are explained.
INTRODUCTION
The flow of streams and canals is not constant but fluctuates naturally due to
variations in precipitation and runoff, and artificially in response to man's
activities. The effective development and management of surface waters depends
upon a knowledge of the flow characteristics of streams and canals. Design and
operation of flood-control projects and optimum utilization of land within the
project areas requires knowledge of the frequency and size of floods. Likewise,
the effective design and operation of water intake structures and systems, such
as for municipal, industrial, and irrigation uses, for disposal of sewage and other
wastes, and for recreation is dependent upon knowledge of the frequency,
duration, and amount of low or sustained flows.
The primary purpose of this report is to present compilations of statistical
summaries of flow duration and low and high flows at gaging stations in Florida.
These summaries will provide a common foundation for use in hydrologic
investigations, for development and management of the surface water resources,
and for administration of the Florida Water Resources law which was enacted by
the Legislature of the State of Florida in 1961.
These statistical summaries provide the basis for an interpretative report
which will portray the characteristics of flow of the various streams of Florida
and describe their differences and the causes of these differences.

SCOPE
Three types of statewide streamflow summaries are presented in this report -
flow duration, low flow, and high flow. Only limited data are given for gaging
stations at which the flows are reversed by tides or by water-management
practices. The technique for using each of the summaries to determine flow
characteristics is explained and illustrated.

BUREAU OF GEOLOGY

The first part of the report explains concepts, the record selection, the three
summaries, and the techniques for using the summaries. The second part of the
report presents the summaries (flow duration, the lowest mean discharge, and
highest mean discharge for selected consecutive periods each year) for each
gaging station.
All summaries for this report were processed by an electronic computer
except those for about 30 gaging stations at which reverse flow occurs.

ACKNOWLEDGMENTS
This report was prepared by the Water Resources Division, U. S. Geological
Survey, under the general supervision of C. S. Conover, District Chief, as part of
a statewide cooperative program with the Bureau of Geology, Florida
Department of Natural Resources. Streamflow records were obtained by the U.
S. Geological Survey from the continuing network program and from special
investigations conducted in cooperation with several State and Federal agencies.
Data contained in the statistical summaries were processed by the Automatic
Data Processing Section in Washington, D. C.
SELECTION OF DISCHARGE RECORDS
Records of discharge at a network of gaging stations on streams and canals in
Florida have been collected and published by the U. S. Geological Survey on a
continuing basis since about 1930. Records for a few stations are available prior
to 1930.
This report includes descriptions, duration tables, low-flow, and high-flow
sequence tabulations for stream-gaging stations with one or more complete years
of daily discharge records through 1965 (see figure 1 for the period of record for
each gaging station). Complete statistical summaries are not given for gaging
stations on tide-affected streams and canals.
Figure I lists gaging stations in downstream order (the same order in which
the summaries are presented), the national identification number, the state basin
number, and shows, by the bar charts years of record at each gaging station for
which statistical summaries or other data are presented.

STATION DESCRIPTIONS
A description of each gaging station which contains information that should
be considered when using the data precedes each data summary. The following
headings are listed in each gaging station description: Location, Drainage area,
Records available, Gage, Average discharge, Extremes, and Remarks. The
location and drainage area were determined using the best maps available.
"Records available" denote the periods for which there are published records for

the particular station. The type and datum of the gage above mean sea level are
given under "Gage." The average discharge for the period of record is given
under "Average discharge." Average discharge is not supplied for stations having
less than five complete years of record. Under "Extremes" the maximum and
minimum discharges and gage heights for the period and for some stations the
maximum known discharge and/or gage height predating the period of record are
given. In the "Remarks" paragraph, supplemental information is given.
Data for gaging stations are presented in downstream order within the river
basins and coastal areas as listed in the "Contents". Stations on a tributary
between two main-stem stations are listed between the two main-stem sites.
Indentations in the station listing in the "Contents" are made to show the order
of rank between the main stem and a tributary.
EXPLANATION OF TABLES
The statistical summaries for each gaging station are explained in detail by
inset notes on the sample shown in figure 2.
The flow-duration tables and summaries of consecutive highest mean
discharge for Florida are computed by the water year (October 1 to September
30), for the area west and north of the St. Marys-Suwannee River basins divide
(see figure 3), and by the calendar year for the area south of this divide. For
stations west and north of the St. Marys-Suwannee divide the low-flow climatic
year begins April 1. For stations on the peninsula south of the St.
Marys-Suwannee divide the climatic year begins July 1. These two climatic years
were used to prevent dividing the low-flow periods in enumerating consecutive
days of low flow for each class interval.
Comparison of the seasonal variation of median discharges at two gaging
stations is shown in figure 4. The Ochlockonee River near Havana is west of the
St. Marys-Suwannee divide, and the Kissimmee River near Okeechobee is south
of this divide.

LOW FLOW
The second summary presented is the annual low-flow table which shows the
lowest daily mean discharge for selected number of consecutive days.
Eleven headings selected for periods ranging from 1 to 274 consecutive days
are listed as shown in figure 2 opposite the climatic year column. Lowest mean
discharge, in cubic feet per second, is shown in the body of the table for the
number of consecutive days indicated by the column headings and for climatic
years given in the first column. The tables provides the data needed for
preparation of low-flow frequency curves.

HIGH FLOW

The annual high-flow table, which is the third summary included for each

gaging station, as illustrated in figure 2, is presented in the same manner as that

for low flow with two exceptions: (1) water year (ending September 30), or

calendar year are used instead of climatic year, as explained previously, in order

that all periods of consecutive days selected for high flows are included entirely

within each year;and (2) use of the heading of 15 consecutive days instead of 14

preselectedd in programing for the computer). This table provides the data

needed to prepare frequency curves which give a clearer interpretation of the

frequency of high flows.

FLOW DURATION

The first summary consists of two related tables-the annual flow-duration
table, as illustrated on figure 2, shows the number of daily mean discharges in
about 30 different classes for each water year or calendar year as listed in the
first column. The other column headings across the table are numbers that
designate classes of discharge. Class limit is the lowest discharge that would be
contained in that class and is listed, in cubic feet per second, in the
flow-duration summary table. The first table shows the number of days that the
daily discharge equaled or exceeded the class limit of each class, but was less
than the class limit of the next higher class. The last column in the annual table
is the sum of all daily discharges for each year.

The flow-duration summary table, which is the second part of the two related
tables illustrated in figure 2, gives the percentage of time for the period of record
in which the streamflow equaled or exceeded a particular discharge. This table is
generally used for preparation of a flow-duration curve for the period of record.
Similar tables can be prepared manually for any number of years listed above in
the annual flow-duration table. The total number of days in the period of record
that discharge equaled or exceeded the class limit of a particular class but was
less than the class limit of the next higher class are given in the tables. The
accumulated number of days in the period of record that discharge equaled or
exceeded the class limit of each particular class are also shown.

TECHNIQUES FOR USING TABLES
FLOW-DURATION CURVES
The flow-duration curve is a cumulative frequency curve that shows the
percentage of time specified discharges were equaled or exceeded in a given
period. The curve is a means of representing the flow characteristics of a stream
throughout the range of discharge. A flow-duration curve (Searcy, 1959) can be
constructed from the flow-duration summary by plotting the discharges as
ordinates and the percentages as abscissas. Smooth curves are usually drawn to
fit the plotted points, but straight lines can be used to connect the points if it is
desired to avoid introducing interpretations.
The shape of a duration curve reflects the topographic, hydrologic, and
geologic characteristics of the drainage area above the gaging site. A curve with a
steep slope throughout denotes a stream whose flow is highly variable and
largely from direct runoff. A curve with a flat slope indicates that flow is derived
from surface or ground-water storage. For example, the duration curve for
Suwannee River at White Springs (figure 5), has a steep slope for the range of
flow except at the lower end. The steep slope indicates that the discharge, which
is highly variable, results from direct runoff; the lower end of the curve flattens
slightly denoting ground-water inflow that maintains flow during dry seasons.
The duration curve for Suwannee River at White Springs shows that a daily
discharge of 10 cubic feet per second (cfs) was exceeded or at least equaled on
99 percent of the days in the periods 1907-08 and 1928-65. The duration curve
also shows that the median or normal discharge (daily discharge was equaled or
exceeded 50 percent of days) was 700 cfs.

the particular station. The type and datum of the gage above mean sea level are
given under "Gage." The average discharge for the period of record is given
under "Average discharge." Average discharge is not supplied for stations having
less than five complete years of record. Under "Extremes" the maximum and
minimum discharges and gage heights for the period and for some stations the
maximum known discharge and/or gage height predating the period of record are
given. In the "Remarks" paragraph, supplemental information is given.
Data for gaging stations are presented in downstream order within the river
basins and coastal areas as listed in the "Contents". Stations on a tributary
between two main-stem stations are listed between the two main-stem sites.
Indentations in the station listing in the "Contents" are made to show the order
of rank between the main stem and a tributary.
EXPLANATION OF TABLES
The statistical summaries for each gaging station are explained in detail by
inset notes on the sample shown in figure 2.
The flow-duration tables and summaries of consecutive highest mean
discharge for Florida are computed by the water year (October 1 to September
30), for the area west and north of the St. Marys-Suwannee River basins divide
(see figure 3), and by the calendar year for the area south of this divide. For
stations west and north of the St. Marys-Suwannee divide the low-flow climatic
year begins April 1. For stations on the peninsula south of the St.
Marys-Suwannee divide the climatic year begins July 1. These two climatic years
were used to prevent dividing the low-flow periods in enumerating consecutive
days of low flow for each class interval.
Comparison of the seasonal variation of median discharges at two gaging
stations is shown in figure 4. The Ochlockonee River near Havana is west of the
St. Marys-Suwannee divide, and the Kissimmee River near Okeechobee is south
of this divide.

LOW FLOW
The second summary presented is the annual low-flow table which shows the
lowest daily mean discharge for selected number of consecutive days.
Eleven headings selected for periods ranging from 1 to 274 consecutive days
are listed as shown in figure 2 opposite the climatic year column. Lowest mean
discharge, in cubic feet per second, is shown in the body of the table for the
number of consecutive days indicated by the column headings and for climatic
years given in the first column. The tables provides the data needed for
preparation of low-flow frequency curves.

LOW-FLOW FREQUENCY CURVES
Data in the annual low-flow tables can be used to construct frequency
curves. By use of these frequency curves the average number of years between
recurrence of similar low flows can be estimated.
As an example, the low-flow frequency curves for Suwannee River at White
Springs for 30 and 274 consecutive days are shown in figure 6. The 30-day
curve shows that the lowest mean discharge for 30 consecutive days is expected
to be less than 10 cfs at intervals that average 20 years in length. The curves are
prepared from the data in the annual low-flow table by following these steps:
1. Array the lowest mean discharges for a selected number of
consecutive days in ascending order of magnitude (beginning with
number 1 for the lowest discharge).
2. Assign order numbers to the discharge.
3. Compute the recurrence interval for each discharge by the formula
(N + 1)/M, where M is the assigned order number and N is the total
number of years for which discharges were ranked.
4. Plot each discharge as an ordinate against its corresponding
recurrence interval as an abscissa and draw a smooth curve through
the plotted points.
The user must understand that the recorded low-flow extremes may be
exceeded by those outside the period of record, and that the real time interval
between low flows of the same magnitude may vary considerable.

HIGH-FLOW FREQUENCY CURVES
The technique used in the preparation of high-flow frequency curves is
similar to that of low-flow frequency curves, except that the discharge for the
selected number of days are assigned order numbers from the discharge of
greatest magnitude (number 1) to the discharge of least magnitude. High-flow
frequency curves for Suwannee River at White Springs for 30 and 274
consecutive days are shown in figure 7. The smoothed 30-day curve for
Suwannee River at White Springs shows that the highest mean discharge for 30
consecutive days is expected to be greater than 15,000 cfs at intervals that
average 20 years in length.
The amount by which annual high-flow frequency curves differ throughout
time is influenced largely by climate and topography while climate and geology
have the greatest influence on annual low-flow frequency curves.
