Introduction 1

Magnitude and Frequency of Low Flows in the

Suwannee River Water Management District, Florida

By G.L. Giese and M.A. Franklin

Abstract

Low-flow frequency statistics for 20 gaging stations having at least 10 years of continuous record and

31 other stations having less than 10 years of continuous record or a series of at least two low-flow measurements are presented for unregulated streams in the

Suwannee River Water Management District in northcentral Florida. Statistics for the 20 continuous-record

stations included are the annual and monthly minimum consecutive-day average low-flow magnitudes

for 1, 3, 7, 14, and 30 consecutive days for recurrence

intervals of 2, 5, 10, 20, and, for some long-term stations, 50 years, based on records available through the

1994 climatic year. Only the annual statistics are

given for the 31 other stations; these are for the 7- and

30-consecutive day periods only and for recurrence

intervals of 2 and 10 years only. Annual low-flow frequency statistics range from zero for many small

streams to 5,500 cubic feet per second for the annual

30-consecutive-day average flow with a recurrence

interval of 2 years for the Suwannee River near Wilcox (station 02323500). Monthly low-flow frequency

statistics range from zero for many small streams to

13,800 cubic feet per second for the minimum 30-consecutive-day average flow with a 2-year recurrence

interval for the month of March for the same station.

Generally, low-flow characteristics of streams in

the Suwannee River Water Management District are

controlled by climatic, topographic, and geologic factors. The carbonate Floridan aquifer system underlies,

or is at the surface of, the entire District. The terrane’s

karstic nature results in many sinkholes and springs. In

some places, springs may contribute greatly to low

streamflow and the contributing areas of such springs

may include areas outside the presumed surface drainage area of the springs. In other places, water may

enter sinkholes within a drainage basin, then reappear

in springs downstream from a gage. Many of the

smaller streams in the District go dry or have no flow

for several months in many years.

In addition to the low-flow statistics, four synoptic low-flow measurement surveys were conducted

on 161 sites during 1990, 1995, and 1996. The measurements were made to provide “snapshots” of flow

conditions of streams throughout the Suwannee River

Water Management District. Magnitudes of low flows

during the 1990 series of measurements were in the

range associated with minimum 7-consecutive-day 50-

year recurrence interval to the minimum 7-consecutive-day 20-year recurrence interval, except in Taylor

and Dixie Counties, where the magnitudes ranged

from the minimum 7-consecutive-day 5-year flow

level to the 7-consecutive-day 2-year flow level. The

magnitudes were all greater than the minimum 7-consecutive-day 2-year flow level during 1995 and 1996.

Observations of no flow were recorded at many of the

sites for all four series of measurements.

INTRODUCTION

In recent years there has developed a better

awareness that natural systems such as wetlands, flood

plains, native ecological communities, and aquifer

recharge areas within the 7,640-square-mile SRWMD

(Suwannee River Water Management District) (fig.1)

provide vital water-related functions. These functions

include water-quality treatment, water supply, flood

water conveyance and attenuation, fish and wildlife

habitat, and recreational and economic values. These

systems depend on the maintenance of the natural

variability of the hydrologic cycle as reflected by the

magnitude, duration, and timing of changing streamflow, rising and falling water levels of lakes, rivers,

and aquifers, and interaction of surface and ground

on the natural systems and their functions. Presently,

however, natural-system hydrologic requirements

must be better understood to establish minimum flow

and water-level requirements that will allow adequate

water to balance present and future needs of the natural system with those of the human population.
Statistics Used In This Report 3

Quantification of the natural hydrologic regime that

has shaped the current natural system is basic to developing this understanding and achieving this balance.

The USGS (U.S. Geological Survey) and the

SRWMD entered into a cooperative agreement in

1994 wherein the USGS will provide, in the course of

a long-term program of investigation, the hydrologic

information needed for the SRWMD to establish minimum flow and water level requirements for surface

and ground waters of the SRWMD. This report is one

of the program products and describes the magnitude

and frequency of low streamflows.

Purpose and Scope

This report (1) discusses in general the factors

affecting low-flow characteristics of streams, (2) presents commonly used low-flow statistics for 20 continuous-record and 31 other stations representing

unregulated streamflow, based on records collected

through the 1994 climatic year (April 1 of the namesake year through March 31 of the following year),

and (3) presents the results of four synoptic low-flow

measurement surveys at 161 sites performed during

1990-96. Statistics included for analysis for continuous-record stations are monthly and annual 1-, 3-, 7-,

14-, and 30-consecutive day low flows for recurrence

intervals of 2, 5, 10, 20, and, for some stations, 50

years. Only the annual statistics for the 31 other stations, are given for the 7- and 30-consecutive-day

periods, and these for recurrence intervals of 2, 5, 10,

and 20 years. The 20 continuous-record stations all

have at least 10 years of continuous record and the

other 31 stations have less than 10 years of continuous

record or at least two low-flow measurements.

Previous Studies

Rumenik and Grubbs (1996a) presented lowflow frequency characteristics for 216 continuousrecord and 242 partial-record stations for Florida,

based on streamflow records collected through the

1987 water year (the 12-month period beginning October 1 and ending September 30). Rumenik and Grubbs

(1996b) discussed several methods for estimating lowflow frequency characteristics at ungaged sites in

northern Florida, including the Santa Fe River Basin.

Franklin and others (1994) gave historical consecutive-day minimum average discharges for 27 gaging

stations in the SRWMD through the 1993 water year,

but did not determine recurrence intervals in that

study. Hunn and Slack (1983) described stream-aquifer relations in the Santa Fe River basin and provided

low-flow frequency characteristics for six gaging stations through the 1976 water year. Hammett (1985)

presented low-flow frequency characteristics for

streams in west-central Florida including the Waccasassa River, based on records collected through the

1981 water year.

STATISTICS USED IN THIS REPORT

Low flow of streams under natural conditions is

usually comprised mostly of ground water, with little

or no overland runoff component. Statistics describing

the low flow of streams are useful in assessing water

supply potential and the ability of streams to assimilate waste discharges. These statistics, together with

information on water quality, may also be used as an

index of the biological potential of streams. The meaning of the monthly and annual low-flow statistics for

1-, 3-, 7-, 14- and 30-consecutive days for recurrence

intervals of 2, 5, 10, 20, and 50 years used in this

report may be illustrated by the following example

explanations. The low-flow Q7,10 is the annual minimum 7-consecutive-day low flow which will be

exceeded in 9 out of 10 years, on average, or, stated

another way, the probability is one in ten (0.1) that the

minimum 7-consecutive day average low flow in any

year will be less than the low-flow Q7,10. As another

example, the low-flow Q30,50 is the annual minimum

30-consecutive-day average low flow that will be

exceeded in 49 years out of 50, or, stated another way,

the probability is one in 50 (0.02) that the minimum

30-consecutive day average low flow in any year will
4 Magnitude and Frequency of Low Flows in the Suwannee River Water Management District, Florida

be less than the low-flow Q30,50. Other annual statistics are interpreted similarly. The annual statistics are

analyzed by the climatic year for north Florida, which

begins April 1 of the namesake year. Monthly statistics are interpreted in a parallel manner to the annual

statistics, except that months are considered separately. For example, the low-flow Q7,10JUL is the minimum 7-consecutive day low flow that will be

exceeded in 9 out of 10 Julys.

Periods of low flows are often periods of maximum stress for aquatic species. Dissolved oxygen may

be at a minimum at such times and concentrations of

harmful substances may be at a maximum. Often, species may tolerate such adverse conditions for brief

periods, but may experience high mortality rates under

prolonged exposure. The logic of selecting various

consecutive-day periods for analysis is related to the

proposition that different species may have different

periods of tolerance for given types of stress. The use

of 1-, 7-, and 30-consecutive day periods, in particular,

is based partly on the fact that many anthropogenic

activities impacting streamflow and quality have daily,

weekly, and monthly cycles. For example, many

industries operate 8 hours a day then shut down for

16 hours; also, they may operate 5 days, then shut

down for two.

Monthly low-flow statistics are given because

lowest annual streamflows are not equally distributed

among the months of the year and only low-flow magnitudes during certain periods are of interest for many

uses, both natural and anthropogenic. For example,

low flows as related to fish spawning may only be of

concern during certain months and availability of

water for water supply augmentation may only be

needed during assigned months of the year. It should

be noted that the magnitudes of the monthly statistics

are equal to or greater than the annual statistics. If

periods longer than a month had been chosen for analysis (for example, seasonal statistics), the magnitudes

would have been equal to or greater than annual statistics but equal to or less than those of the minimum

month included in the longer time period.

FACTORS AFFECTING LOW-FLOW

CHARACTERISTICS OF STREAMS

Generally, controls on low-flow characteristics

of streams fall in three categories--climatic, topographic, and geologic. The amounts and distribution of

precipitation control low-flow characteristics such

that, all other factors being equal, areas receiving

higher amounts of annual precipitation and less temporal variability have higher values for low-flow statistics than areas receiving lower amounts of

precipitation and greater temporal variability. The

SRWMD receives an average of 56 inches per year of

precipitation (SRWMD, 1995), with July and August

being the wettest months with two drier periods in the

early fall and late spring. Areas closest to the Gulf of

Mexico receive more precipitation than those further

away, largely because of summer convective storms

fueled by moisture from the Gulf. Generally, there are

two annual low-flow periods in the SRWMD which

correspond closely to the two drier periods. The lowest annual streamflows usually do not occur in midwinter, both because precipitation is higher in the

winter months than in the early fall (October and

November) and late spring (May and June) and

because evapotranspiration demands are at an annual

low during those months. Although evapotranspiration

demands are at a peak in the summer months, much of

the higher precipitation during those months goes to

recharge the ground water system, resulting in higher

water levels to sustain base flow of streams and higher

discharges than is the case during much of the fall and

late spring.

Topography also exerts considerable control

over low-flow characteristics of streams in the

SRWMD which lies within the Southeastern Coastal

Plain province of the United States, as delineated by

Fenneman (1938). The District is covered by three

physiographic regions of this province--the Gulf

Coastal Lowlands, the Northern Highlands, and the

River Valley Lowlands (fig. 2).

Topographic relief is not great enough to produce significant orographic effects with regard to the

amounts and areal distribution of precipitation in the

District. Maximum elevation in the SRWMD is only

about 230 ft above NGVD (SRWMD, 1995), in the

Northern Highlands region. However, the amount of

water available from ground water storage to support

streamflow is controlled in part by topography. Driving head differences between streams and aquifer systems during periods of no precipitation are partly a

reflection of topographic relief.

Geology greatly affects low flows in the

SRWMD. The carbonate Floridan aquifer system

underlies or is at the surface of the entire SRWMD.

The karstic terrane includes many springs and sinkholes. Springs may contribute greatly to low
Low-Flow Frequency Analysis 5

streamflow, and the contributing areas of such

springs may include areas outside the presumed surface drainage area of the springs. Conversely, water

may enter sinkholes within a drainage basin, then

reappear in springs downstream from a gage. Thus,

the actual contributing drainage area at a gage may

be more or less than would be indicated by surface

topography. Primarily because of the effects of

these karstic features on streamflow, low-flow characteristics of streams in the SRWMD may exhibit

greater variability on a per-square-mile basis than

non-karstic areas with similar climate and topography. Thus, prediction of low-flow characteristics at

an ungaged stream site based on characteristics at a

nearby gaged site carries a great deal of uncertainty.

Many of the smaller streams in the SRWMD go dry

or have no flow for several months of the year,

partly due to geology-related controls on streamflow. Others streams which are spring-fed may sustain relatively high streamflow while otherwise

similar nearby streams may be dry or have no flow.

LOW-FLOW FREQUENCY ANALYSIS

The data base used for analysis of low-flow

characteristics in the SRWMD includes daily discharges for 20 continuous-record gaging stations having at least 10 years of record as of the end of the 1994

climatic year, and 31 other stations having less than 10
6 Magnitude and Frequency of Low Flows in the Suwannee River Water Management District, Florida

years of continuous record or at least two discharge

measurements during low-flow periods (fig. 1). Lowflow statistics defined for the 20 continuous-record

gaging stations were developed by generating a time

series of annual and monthly minimum average flows

for 1, 3, 7, 14, and 30 consecutive days for each climatic year for each station. The values in each of the

series were ranked from smallest to largest and fitted

mathematically to the assumed log-Pearson type III

distributions. The fitted distributions were then

screened for outliers and adjusted graphically, if necessary. These procedures are given in detail by Riggs

(1972). An example of fitted low-flow frequency

curves for 1- and 30-consecutive-day periods for station 02321500, the Santa Fe River at Worthington

Springs, is shown in fig. 3.

Where one or more zero values were present in

a time series of annual low flows, a conditional probability adjustment was used (Interagency Advisory

Committee on Water Data, 1982; Thomas, 1991).

Only non-zero values are used in the log-Pearson

is adjusted using years of zero values; this results in

greater probabilities of occurrence of the non-zero values than would be the case if the conditional adjustment was not performed. The recurrence intervals

selected for tabulation from fitted distributions were

the 2-, 5-, 10-, 20-, and, for some long-term gaging

stations, 50-year recurrence intervals (app. I).

Statistics for only annual values are given in

Appendix I for the 31 other stations, and these for the

7- and 30-consecutive day periods only, for recurrence

intervals of 2 and 10 years, only. Many of the statistics

for the 31 other stations are identical to those given in

Rumenik and Grubbs (1996). Values differ from those

given in that report in cases where the additional years

of record available at a continuous-record station were

available, or where additional years of record were

available at a continuous-record station used as an index

station for correlation with a partial-record station, or

additional measurements at the partial-record station

changed low-flow statistics at the partial-record site by

more than 10 percent from Rumenik and Grubbs values,

as determined by graphical log-log regression. The lowflow frequency values for the partial-record stations

reported in Rumenik and Grubbs (1996) were determined by first developing a log-log regression between

base flow measurements at the partial-record station and

daily mean flows at a nearby long-term continuousrecord gage (index station) in the same precipitation

pattern as the partial-record station. Then, knowing the

low-flow statistic for the index station, the corresponding statistic for the low-flow partial-record station was

determined from the relation. An example of this correlation technique is shown in fig. 4, in which station

02321500, Santa Fe River at Worthington Springs, is

the index station and station 02321600, Olustee Creek

near Lulu, is the low-flow partial-record station. It

should be noted that the low-flow statistic for the parFigure 4. Discharge relation used to estimate selected low-flow characteristics at partial-record station 02321600, Olustee

Rumenik and Grubbs (1996a) used a correlation

technique called maintenance of variance extension,

type 1, MOVE.1 (Hirsch, 1982), rather than this

graphical technique, to develop the relation between

the index station discharge and the partial-record station discharge in cases where 10 or more base flow

measurements were available at a partial-record station. MOVE.1, unlike least squares regression, maintains the sample mean and variance of the dependent

variable (Hirsch, 1982). Also, Stedinger and Thomas

(1985) report that MOVE.1 provides nearly unbiased

estimates of low-flow frequency characteristics and

does not tend to overestimate low-flow characteristics.

Where fewer than 10 base flow measurements

were available at a low-flow partial-record site, a best

fit straight line was drawn by hand on log-log paper of

plotted measured discharge at the partial-record site

(dependent variable) and mean daily discharge at the

continuous record index station (independent variable), as illustrated in the previous example (fig. 4).

For annual values, low-flow statistics ranged

from zero for many small streams to a maximum of

5,500 ft3/s for the 30-day 2-year annual low flow for

flow statistic was station 02313448, the Little

Wacasassa River near Bronson, with a drainage area of

180 mi2 . The smallest drainage area with a non-zero

value for the Q7,10 flow statistic was station 02322016,

Blues Creek near Gainesville, with a drainage area of

5.12 mi2

.

LOW-FLOW SYNOPTIC SURVEYS

A total of four series of low-flow measurements

on 161 mostly small streams were conducted during

1990, 1995, and 1996,. The location of the measurement sites is shown in figure 5, and the measurement

values are given in Appendix II. These four series of

measurements were each conducted over a period of
Summary 9

several days or weeks during which little or no rain

occurred and conditions were considered to be base

flow. The measurements were made to provide “snapshots” of flow conditions on small streams throughout

the SRWMD. Though the measurements were not

made simultaneously, they are considered to provide a

synoptic view, because general low-flow conditions

did not vary substantially during the course of each

survey. Based on analysis of ambient probabilities of

low-flow occurrence at continuous-record stations

within the SRWMD, low-flow magnitudes during the

August and September 1990 series of measurements

ranged from the Q7,50 to the Q7,20, except in Taylor

and Dixie Counties, where the magnitudes ranged

from the Q7,5 to the Q7,2 level; during the May, June

and July 1995 and the November and December 1995

series, as well as the June 1996 series, the magnitudes

were all greater in magnitude than the Q7,2 level flows.

Observations of no flow were recorded at many of the

individual sites during one or more of the surveys. It is

worth noting that if a particular low-flow statistic for a

given site is known, then any low-flow statistic at that

site for a shorter consecutive-day period and/or a

longer recurrence interval will be less than or equal to

that value. For example, for station 02326500, the

Aucilla River at Lamont, the annual Q14,10 low-flow

value is zero (Appendix 1). Therefore, by the above,

the annual Q14,20 and the Q14,50 values are also zero.

Also, the Q7,10, the Q3,10, and the Q1,10 are zero.

SUMMARY

Low-flow frequency statistics for 20 gaging stations having at least 10 years of continuous record and

31 other stations having less than 10 years of continuous record or at least two low-flow measurements are

presented for unregulated streams in the Suwannee

River Water Management District in north-central

Florida. For the 20 continuous-record stations having

at least 10 years of record, statistics included are the

annual and monthly minimum consecutive-day average discharges for 1, 3, 7, 14, and 30 consecutive days

for recurrence intervals of 2-, 5-, 10-, 20-, and, for

some long-term stations, 50-year recurrence intervals,

based on records available through the 1994 climatic

year. Only annual statistics for recurrence intervals of

2 and 10 years are given for the 31 other stations for 7-

and 30-consecutive day periods only. Annual low-flow

statistics ranged from zero for many statistics for small

streams to a maximum of 5,500 ft3/s for the Q30,2 lowflow for station 02323500, the Suwannee River near

Wilcox (drainage area 9,640 mi2). Monthly low-flow

statistics ranged from zero for many small streams to

13,800 ft3

/s for the Q30,2MAR for the same station.

Generally, low-flow characteristics of streams in

the Suwannee River Water Management District are

controlled by climatic, topographic, and geologic factors. Geologic factors, in particular, greatly affect low

flows in parts of many streams in the Suwannee River

Water Management District. The carbonate Floridan

aquifer system underlies or is at the surface of the

entire SRWMD. The resulting karstic nature of much

of the terrane results in many sinkholes and springs.

Water may disappear into sinks in streambeds and

reappear several miles downstream. Springs may contribute greatly to low streamflow, and the contributing

areas of such springs may include areas outside the

surface drainage area of the springs. In other places,

water may enter sinkholes within a drainage basin,

then reappear in springs downstream from a gage.

Thus, the actual contributing drainage area at a gage

may be more or less than would be indicated by surface topography. Many of the smaller streams in the

SRWMD go dry or have no flow for several months in

many years.

Four series of low-flow measurements on 161

mostly small streams were conducted during 1990,

1995, and 1996. The measurements were made to provide snapshots of flow conditions on small streams

throughout the SRWMD. Low-flow magnitudes during the 1990 series of measurements ranged from the

Q7,50 to the Q7,20 level, except for Taylor and Dixie

Counties where magnitudes ranged between the Q7,5

and Q7,2 levels; during 1995 and 1996, magnitudes

were all greater than the Q7,2 level. Observations of no

flow were recorded at many of the sites during all four

series of measurements.
