STREAM-TEMPERATURE CHARACTERISTICS

IN GEORGIA

By T.R. Dyar and S.J. Alhadeff

ABSTRACT

Stream-temperature measurements for 198periodic and 22 daily record stations were analyzedusing a harmonic curve-fitting procedure. Statistics ofdata from 78 selected stations were used to compute astatewide stream-temperature harmonic equation,derived using latitude, drainage area, and altitude fornatural streams having drainage areas greater than about40 square miles. Based on the 1955-84 referenceperiod, the equation may be used to compute long-termnatural harmonic stream-temperature coefficients towithin an on average of about 0.4 0 C.

Basin-by-basin summaries of observed long-termstream-temperature characteristics are included forselected stations and river reaches, particularly alongGeorgia's mainstem streams. Changes in the stream-temperature regimen caused by the effects ofdevelopment, principally impoundments and thermalpower plants, are shown by comparing harmonic curvesand coefficients from the estimated natural values to theobserved modified-condition values.

INTRODUCTIONStream-temperature characteristics are used to

assess, manage, and protect the water resources ofGeorgia. As body temperature is an indicator of humanhealth, water temperature is an indicator of the ability ofa stream to sustain aquatic life and assimilate wastes.

Stream-temperature data are important inputs forstream water-quality models. In 1974, the GeorgiaDepartment of Natural Resources, EnvironmentalProtection Division (EPD), with assistance from theU.S. Geological Survey (USGS), designed andconstructed a seasonal stream assimilative capacity(SAC) model as an aid to stream assessments inGeorgia. The SAC model has been used to providestatistics for the design and operation of waste-treatmentfacilities to help ensure compliance with variouswater-quality standards and to quantify streamassimilative capacity.

Stream-temperature data along with curvesdetermined by least-squares simple harmonic fitting ofthe data were presented for 146 stream-temperaturestations in Georgia by Dyar and Stokes (1973). Thestream-temperature information for these 146 stations issuitable for input to the SAC model or other such water-quality models. However, stream-temperaturecharacteristics have not been estimated for manystreams in Georgia for which no data or insufficient dataexist. Thus, a simple, reliable method is needed toestimate stream-temperature characteristics for siteswhere little or no data exist.

This study was conducted by the USGS, incooperation with the EPD. The stream-temperaturedata used in this study were collected in cooperationwith EPD and other Federal, State, and local agencies.

Purpose and Scope

This report summarizes the water-temperaturecharacteristics of selected stream stations in Georgia,and provides a harmonic equation suitable forestimating natural seasonal water-temperaturecharacteristics of most Georgia streams. The harmonicequation described in this report is based on estimatesof natural seasonal stream-temperature characteristicsfor non-tidal streams in Georgia having drainage basinsgreater than 40 square miles (mi 2). Stream-temperaturecharacteristics computed by the harmonic equationpresented in this report may be compared to observedstream-temperature data to evaluate how seasonalstream-temperature characteristics of a particular streammay be deviating from estimated natural characteristics.

This report builds upon the Statewide summaryreport of stream-temperature data presented by Dyar andStokes (1973). Seasonal stream-temperaturecharacteristics are computed and analyzed from datacollected by USGS at 198 periodic and 22 continuousrecord stream-temperature stations through 1984,including most of the 146 stations reported by Dyarand Stokes (1973).

The harmonic equations for computing naturalseasonal stream-temperature characteristics presentedin this report are based on analyses of 78 stream-temperature stations having records from about1955-84. Analyses of records collected subsequentto 1984 could cause changes in these equations.However, based on comparisons of the analyses inthis report and Dyar and Stokes (1973), changes likelywill occur slowly.

Throughout this report, the term "natural" isintended to describe stream temperatures that arerelatively unaffected by human activities, includingsuch practices as waste-water return, reservoiroperation, diversions, or proximity to urban areas.The term "natural" is subjective and rigorous evaluativeprocedures are not applied to prove the validity of itsuse. Similarly, the term "modified" connotes thatobserved stream temperatures likely are affected byhuman activities. The terms "stream temperature,""water temperature," and "temperature" are synonymousthroughout this report. Finally, the terms "station" and"stream station" refers to locations where systematicstream-temperature data are available; whereas, the term"site" and "stream site" refers to locations where little orno data are available.

Previous Investigations

Numerous previous stream-temperature studieswere referred to during the compilation and analysis ofthe information contained in this report. Statewideinventories of continuous or periodic records of streamtemperatures collected primarily by the USGS werepresented for California in a series of reports byBlodgett (1970-72) and for North Carolina by Woodard(1970). More descriptive, graphic summaries onregional-basin, statewide, or national scales have takenseveral forms. Maps depicting gross areal variability ofselected stream-temperature characteristics have beenprepared for Florida (Anderson, 1971), for Washington(Collings and Higgins, 1973), and for the Nation as awhole (Blakely, 1966; Steele and others; 1974,Hawkinson and others, 1977). Plots of annual stream-temperature variations have been reported for numerousstations in Montana (Aagaard, 1969), for selected sitesin Georgia (Lamar, 1944), for the upper Delaware Riverbasin in New York (Williams, 1971), and for theDelaware River at Trenton, N.J. (McCarthy andKeighton, 1964).

Annual seasonal temperature variations weredistinguished from shorter-term daily variations instream temperature in reports by Calandro (1969) andWilliams (1971). Studies correlating air and watertemperatures on an annual or seasonal basis includestudies by Kothandaraman and Evans (1972), Andersonand Faust (1973), Williams (1971), and Steele (1974).

Based on seasonal cyclical patterns of stream-temperature records commonly observed at numerousmeasuring stations, a leastlsquares, harmonic-analysisregression fit of annual variability was proposed byWard (1963). An evaluation of incremental benefitsobtained by imposing higher-order harmonics in theanalysis (Thomann, 1967; Kothandaraman, 1971)concluded that a single~harmonic analytical depictionof seasonal variations in stream temperatures explains85-95 percent of the observed variability in annualrecords. A modification of the basic single-harmonicapproach was reported by Tasker and Burns (1974)for specific application to regions where streams areaffected by ice cover for prolonged periods.

In addition to the above reports on graphical oranalytical representations of seasonal variations instream temperature, several other investigations warrantmentioning. Detailed studies, generally on smallstreams, have described and evaluated variousenvironmental factors affecting stream temperatures

(Pluhowski, 1970; Moore, 1967). Collings andHiggins (1973) related stream-temperature harmoniccoefficients to selected characteristics of a basin usinga multiple-regression approach and found the mostfrequently occurring, statistically significant variableswere drainage area, channel slope, mean basinaltitude, and mean annual streamflow. Gilroy andSteele (1972) evaluated the effects of reduced samplingfrequencies of stream-temperature measurements asdepicted by harmonic coefficients for selectedlong-term daily records.

Station-Identification System

The stream-temperature station numbers arebased upon a numbering system which has been usedfor USGS surface-water stations since October 1, 1950.In this system, the station-identification number isassigned according to downstream order and gapsare left in the series of numbers to allow for newstations that may be established; hence, the numbersare not consecutive. The complete number of eachstation, such as 02331655, includes the two-digit partnumber "02" plus the downstream-order number"331655," which can be from 6 to 12 digits (Stokesand McFarlane, 1995). The tables and most figures inthis report adhere to this system.

In figures 1 and 2 of this report, the USGSstream-station numbers are shortened by omitting thefirst two digits. Similarly, in the text of this report, allstream-temperature station names that are referenced toGeorgia cities are shortened to omit the "Ga." part. Forexample, the complete station number and name for theabbreviated "392500, Little River near Roswell," is"02392500, Little River near Roswell, Ga." Otherabbreviated station numbers can be completed similarlywith the exception of stations having abbreviatednumbers greater than'5000-these stations require aleading "03" rather than a leading "02." For example,the complete station number for station 545000 is03545000. The number and name abbreviations areintended to improve the readability of the report. Thetables and most figures in this report contain completestation numbers and names.

Stream-Temperature Data

Periodic and daily stream-temperature data forstreams in Georgia stored in the USGS database through1984 were compiled for evaluation and possible furtheranalyses. The compilation yielded 333 periodic stationshaving 8 or more temperature measurements and 61stations with daily temperature records. Of the 333periodic stations, 198 had five or more years of well-distributed data suitable to determine long-term stream-temperature characteristics (table 1, in back of report).Similar criteria were used to screen the 61 daily recordstations; 22 of these stations were selected as suitablefor harmonic analyses (table 2, in back of report). Allbut four of the daily record stations (02208450,02231000, 02338660, and 02382720, respectively) alsoare periodic stations. The 198 periodic stream-temperature stations selected for analysis are listed intable 1 with their locations shown in figure 1. The 22selected daily stream-temperature record stations arelisted in table 2 and shown in figure 1. The figure alsoshows major river basins and physiographic provincesdiscussed in this report.

Periodic stream temperatures for stations listed intable 1 were measured by holding a thermometer inflowing water and, in most instances, reading thethermometer while the bulb was immersed. Accuraciesof periodic temperature measuring techniques used bythe USGS are within about 0.8 0 C (Moore, 1967,p. 8-14; Rawson, 1970, p. 2-4; Blodgett, 1970, p. 2-3).Because most periodic-temperature measurements aremade during daylight hours, observed streamtemperatures generally are higher than daily meanstream temperatures.

Daily record stream temperatures were collectedby automatic recording equipment or by local observers.A variety of automatic recorders have been used tocollect data over the years. Generally, accuracies ofwater temperatures collected by automatic recordingequipment are within ± 1 ° C (Moore, 1967, p. 8-14;Rawson, 1970, p. 2-4; Biodgett, 1970, p. 2-3). Datacollected by local observers also are believed to bewithin ± 1 0 C.

LONG-TERM STREAM-TEMPERATURECHARACTERISTICS

Dyar and Stokes (1973) demonstrated that annualseasonal or long-term stream-temperaturecharacteristics may be represented by a harmonic(sinusoidal) function of the following form (Ward, 1963;Collings, 1969; and Steele and Gilroy, 1972):

T=M+A [sin (b t+c)] (1)

where

T is the harmonic-mean stream temperature onday "t";

M is the harmonic-mean coefficient or the long-term mean stream temperature for the periodof record used in the analysis;

A is the amplitude coefficient or annual rangein temperature of the harmonic function (orone-half the estimated annual variation instream temperature for the period of record);

b is a constant to convert time of year "t" todegrees of arc;

t is the time of year expressed as a day number,where t = 1 for October 1; and

c is the phase coefficient of the harmonicfunction.

A generalized example of a harmonic temperaturecurve computed from equation (1) is shown in figure 3.Harmonic coefficients for equation (1) (M, A, and c)may be determined by plotting stream-temperaturestation data for the selected period of analysis on asingle annual time segment, without regard to year,and computing the least-square harmonic fit from thedata points. The selected annual time segment is astandard "water year" used by the USGS, whichrepresents a period of October 1 to September 30 ofthe following calendar year.

Stream-temperature data for each station listed intables 1 and 2 were plotted and harmonic-functioncoefficients were computed from a least-squaressinusoidal fit of the data. The computed coefficients,standard errors, and variances are listed in tables 1 and2. Multiple analyses were performed for six periodic

stations (02213500, 02318000, 02336000, 02339500,02392500, and 02394000) because reservoirsconstructed upstream from the stations during the periodof record interrupted the homogeneity of the tempera-ture data. Graphs of the annualized stream-temperaturedata and harmonic-function curves for selected periodicstations listed in table 1 are shown in back of this report.

Natural Stream-Temperature Characteristics

To estimate natural stream-temperaturecharacteristics at ungaged locations, 78 of the 198periodic stream-temperature stations were selected forregression analysis. No continuous-record stations wereselected for analysis because most were located onmodified streams or were already represented byperiodic stations at the same locations. Stations withstream temperatures substantially affected by humanactivities and stations having drainage areas less than40 square miles (mi 2) were excluded from analysis. Tohelp ensure statistical independence, most mainstemstations were excluded. However, 16 stations withdrainage areas greater than 1,000 mi 2 were included toprovide sufficient drainage area variability for theregional analysis. The 78 stations selected for analysisare listed in table 3 (in back of report) and theirlocations and stream names are shown in figure 2.

Several limitations of the data used to computenatural temperature characteristics should be noted.First, for the analysis to be rigorous, only stationshaving completely natural conditions upstreamshould be used. Because some modifications haveoccurred on most major streams, computationof completely natural temperature characteristics wasnot possible. However, natural stream-temperaturesshould predominate at each of the 78 stations used foranalysis (table 3). Second, most periodic datacollection occurs in daylight hours, causing a slighttemperature bias. This bias typically is from about0.5 to I 0 C or less; most bias occurs on smallerstreams during the warmer seasons.

Regression Analysis

To develop regional relations, the harmonic mean(M), amplitude (A), and phase coefficients (c) listed intable 3 were each analyzed by regression analyses; thefollowing multiple-regression function was defined:

y=bo+b 1 *xi+b 2 *x 2 +b 3 *x 3 +...+bn*xn (2)

b0 "... are terms of regression coefficients; and

xl...n are variables of selected basin character-istics considered in the regional analysis.

Independent variables used for the regression includedthe station latitude, drainage area, and altitude (table 1).

Harmonic Mean Coefficient

The empirical equation resulting from theregression analysis to estimate the natural long-termharmonic mean stream-temperature coefficientapplicable throughout the State of Georgia is:

M = 42.68 - 0.833 * L + 0.743 * log D - 0.00133 * E (3)

whereM is the long-term mean stream

temperature or the harmonic meantemperature coefficient, in o C;

L is the station or stream location latitude,in decimal degrees;

D is the station or stream location drainagearea, in square miles; and

E is the station or stream location altitude,in feet above sea level.

Harmonic mean stream-temperature and indepen-dent variable data used in this regression equation arelisted in table 3. The regression yields a standard errorof about 0.4 0 C for the harmonic mean stream-temperature coefficient. Equation (3) accounts for95 percent of the variance, with the latitude componentaccounting for about 49 percent; altitude for about27 percent; and drainage area for about 19 percent.Harmonic mean temperatures tend to increasesouthward and with lower basin altitude.

Residuals obtained by subtracting harmonic meantemperatures determined by regression equation (3)from the values calculated by harmonic analyses ofstation data are shown in figure 5. Negative valuesindicate harmonic mean temperatures computed fromstation data are less than those determined by equation(3). Clusters of both negative and positive residuals areapparent in figure 5; at least one of the larger departuresshown in figure 5 is relatively easy to explain. WestChickamauga Creek near Lakeview (station 03567340)has a residual value of + 1.0 0 C as would be expectedfor any stream in Georgia that flows opposite to theprimary north-to-south direction. However, for the mostpart, the map of residuals (fig. 5) shows random andsmall numerical departures from equation (3).

Natural long-term temperature anomalies can beexpected in some locations in Georgia. For example,stream temperatures in and around Warm Springs, likelywould be higher than values predicted by equation (3).Along the coast and in tidal streams (such as stations02203559, 02203566, 02203570, 02203574,02203578, 02203585, and 02203596), data are scarce.Because stations having sea affects are not included,equation (3) should not be applied to tidally affectedstream sites. Stream locations having drainage areassmaller than about 40 mi 2 or having a very highproportion of streamflow derived from ground-waterinflow upstream may show deviations of 1 0 C ormore from values estimated by equation (3).

The empirical equation used to estimate naturallong-term harmonic-mean temperatures in Georgiastreams predict a maximum high value of about20.5 0 C; such values occur at lower latitudes, loweraltitudes, and in larger drainage basins. The minimumpredicted low value is about 12.3 0 C; values in thisrange occur at higher latitudes, higher altitudes, and insmaller drainage basins. Generally, the harmonic meantemperatures computed from data for the 78 stationsanalyzed (table 3) agree well with those estimated byequation (3).

Amplitude Coefficient

The empirical equation resulting from theregression analysis to estimate the natural long-termamplitude stream-temperature coefficient applicablethroughout the State of Georgia is:

A = -7.40 + 0.947 * log D + 0.426 * L - 0.00075 * E (4)

whereA is the amplitude coefficient in 0 C;

D is the station or stream location drainagearea, in square miles;

L is the station or stream location latitude,in decimal degrees; and

E is the station or stream location altitude,in feet.

Amplitude and independent variable data used inequation (4) are identified in table 3. An areal plot ofthe amplitude coefficients is shown in figure 6. Theregression yields a standard error of about 0.7 ° C.Equation (4) accounts for about 48 percent of thevariance, with the drainage area component accountingfor about 18 percent; latitude for about 18 percent; andaltitude for about 12 percent.

Residuals computed by subtracting amplitudecoefficients computed by equation (4) from the valuescomputed from station data are shown in figure 7. Theresiduals in figure 7 range from an average of about +0.6O C in the Piedmont Province to an average of about -0.3o C for much of the remaining provinces in the State;this indicates that equation (4) tends to underestimatethe harmonic amplitude coefficient in much of thePiedmont, and to overestimate it throughout most of theremainder of the State. Much of the difference in theamplitude coefficients in the two areas may beattributable to natural causes. Many of the negativeresiduals occur on streams having large components ofground-water inflow. For example, a relatively largeproportion of streamflow at Whitewater Creek nearButler (station 02349000), having one of the largestnegative residuals of-1.8 0 C, comes from ground-waterinflow. The large ground-water component also appliesto the Chattooga River at Summerville (station02398000).

Many streams immediately south of the Fall Linealso have relatively large components of ground-waterinflow, as do those in the southern parts of theChattahoochee and Flint River basins in southwesternGeorgia, and in some of the Valley and Ridge Provincewithin the Coosa River basin. Conversely, the highpositive residuals seen at stations in the southernPiedmont Province may be attributable to relativelysmall ground-water inflow to these streams. Also, theband of positive residuals within the Piedmont iscoincident with high population densities and may bepartially attributable to affects of human development.

Estimates of long-term natural harmonic amplitudecoefficients from equation (4) can yield a range ofamplitude from a high value of about 11.2 0 C to a lowvalue of about 5.0 0 C for normal variations of theindependent variables. High values typically occur withlarger drainage areas, higher latitudes, and loweraltitudes. Low values tend to occur with smallerdrainage areas, lower latitudes, and higher altitudes.However, higher altitudes do not occur with lowerlatitudes in the State. From table 3, the maximum long-term natural harmonic-amplitude coefficient is about10.2 0 C for the Flint River near Culloden (station02347500). The minimum amplitude coefficientobserved from the 78 stations analyzed is about 6.2 0 Cfor Whitewater Creek near Butler (station 02349000)(table 3).

The amplitude coefficient of the harmonic functionis useful to determine the high and low stream-temperature regimens, as illustrated by figure 3. Graphsand data included in this report show that the addition ofthe amplitude to the harmonic mean temperatureprovides estimates of average annual maximum streamtemperatures. Similarly, subtraction of the amplitudefrom the harmonic mean yields estimates of averageannual minimum temperatures.

Phase Coefficient

Regression analyses were applied to phase-coefficient data in table 3. No basin or hydrologicparameters were found to be helpful in determining thevalue of the phase coefficient. The natural long-termphase coefficient is a constant of about 2.81 radians. Thestandard error of the phase coefficient is about 0.04radians, amounting to about two days. Long-term mean-temperature values are most likely to occur in naturalstreams in Georgia on about October 19 and April 20.Minimum and maximum long-term natural temperaturesare likely to occur on about January 19 and July 20,respectively. Temperatures near the annual maximumand minimum are likely to persist for several weeks. Forexample, temperatures within 1 ° C of the maximumtemperature are likely to occur from about the end ofJune through mid-August. Similarly, temperatureswithin 1 ' C of the minimum value are likely to occurfrom about the end of December through mid-February.The individual phase-coefficient values for each of theselected 78 stations are plotted on figure 8, indicatingthat the phase-coefficient data are adequately describedby the constant of 2.81 radians.

Statewide Harmonic Equation

Long-term stream-temperature characteristicscommonly are estimated for sites when stream-temperature data are not available or are not practicalto obtain. The harmonic equation to estimate long-termnatural stream-temperature characteristics in Georgia isderived by substituting equations (3) and (4) and theconstant of 2.81 radians into equation (1). The resultingequation to estimate long-term natural stream-temperature characteristics is:

T = 42.68 - 0.833 * L + 0.743 * log D - 0.00133 * E +(0.947 * log D + 0.426 * L - 0.00075 * E - 7.40) *

(sin (2 * n * t/365 + 2,81)) (5)

whereT is the estimated long-term mean-daily

stream temperature in 0 C for theselected day of the year;

L is the station or stream location latitude,in decimal degrees-values rangingfrom about 30.5 degrees to 35 degrees;

D is the station or stream location drainagearea, in square miles-values rangingfrom about 40 to 14,000 mi 2,

E is the station or stream location altitude,in feet-values ranging from about 0 to2,000 feet; and

is incremented day-by-day beginningwith "1" for October I to "365" or "366"for Septembef 30 of a given or leap year,respectively.

The insertion of latitude, drainage area, andaltitude values into equation (5) while incrementing "t"day-by-day throughout a year generates a harmoniccurve which tends to provide a good description ofstream-temperature response to solar radiation, seasonby season, throughout the State.

The harmonic mean and amplitude coefficientsthat are generated by equation (5), hereinafter termedthe "statewide harmonic equation," match the individualharmonic stream-temperature coefficients for the 78natural-condition stations to within an average of about0.4 0 C. When equation (5) is applied to the stream-temperature measurements of the 78 regression-analysisstations shown in table 3, the data mostly appear asnormally distributed about each curve. The standarderror or natural temperature scatter averages about 2.2 0

C (table 3) throughout the State. Likewise, the 95percent probability averages about 1.2 0 C above orbelow the applied statewide harmonic curve. Becauseof the uniform scatter of data about the appliedharmonic curve and the large number of datameasurements used in the computation, upper and lowerbounds in these ranges should give the data user anestimate of natural statistical temperature ranges.

The statewide harmonic equation was derived from78 stations having drainage areas greater than about 40mi2, using temperature data collected from about 1955-84 (table 3). Derivations using other periods of analysis,subsequent data, or different stations could causesomewhat different results.

To evaluate the suitability of the statewideharmonic equation for drainage areas less than 40 mi 2,13 stations having drainage areas ranging from 15 to 37mi2 and having mostly natural stream-temperaturecharacteristics were selected from table 1. For the 13selected stations, the statewide harmonic equationyielded average harmonic temperature coefficients

within about 0.7 0 C of the coefficients computed fromobserved data. This error of prediction for harmonictemperature coefficients is higher than the 0.4 0 Caverage error computed using the 78 larger drainagearea stations from table 3. Though the statistical sampleof 13 stations is small and confined to central andnorthern Georgia streams, the statewide harmonicequation is expected to generate progressively largererrors of prediction for drainage areas less than about15 mi2 . More discussion of applications and limitationsof the statewide harmonic equation is presented infollowing sections of this report.

Harmonic statistics of the daily stream-temperature records (table 2) show that long-termharmonic curves of daily maximum and minimumstream temperatures, typically range from about 1.0 to1.5 0 C above and below, respectively, the long-termharmonic mean curve for stations having drainage areasof about 100 mi2, and about 0.5 0 C above and belowthe long-term mean curve for stations having drainageareas of about 10,000 mi 2. Addition (or substraction) ofthese values to equation (5) and the analysis ofmaximum or minimum monthly observed values fromnearby data can produce good estimates of expectedmaximum or minimum stream-temperature values forany month of the year.

There are some asymmetrical properties of annualstream-temperature characteristics which the sinusoidalfitting process tends to obscure, such as when minimumtemperatures approach freezing. Stream temperaturesthat approach 0 0 C do not fit a sinusoidal distribution.

Perhaps a more important asymmetrical stream-temperature consideration at a station comes from heatflux proportional to streamflow. The annual heat-fluxdistribution is skewed because runoff typicallyincreases, particularly in natural streams, during thecolder December-April period. Examples of thisphenomenon can be observed in stream reaches belowsome reservoirs. The reservoirs act as heat sinks thattend to moderate and lag downstream temperatures.When reservoir storage is large compared to averageannual stream runoff, downstream stream-temperaturecharacteristics may be markedly changed from naturaltemperature characteristics. For example, the annualmean harmonic-stream temperature downstream ofLake Sidney Lanier (Chattahoochee River near Buford,station 02334500) currently is about 9.2 0 C, which isabout 6 0 C below the natural annual harmonic-meantemperature-calculated from equation (5) for thestation-of about 15.3 0 C. Because near-bottom wateris released from Lake Sidney Lanier, the ChattahoocheeRiver downstream from the lake has temperaturecharacteristics of the cool season throughout the year.

Examples of Estimating NaturalStream-Temperature Characteristics

Four examples illustrating uses of stream-temperature data and regression equations presented inthis report are described below. The stations selectedfor discussion range widely in size and geographiclocation and include (1) Panther Creek, a small streamin the upper reaches of the Savannah River basin in theBlue Ridge Province; (2) West Armuchee Creek in theCoosa River basin in the Valley and Ridge Province;(3) Alcovy River in the Altamaha River basin in thePiedmont Province; and (4) Altamaha River about60 miles upstream from its mouth and in the CoastalPlain Province. Each example depicts how a usermight choose to analyze and estimate natural stream-temperature characteristics at the site of interest.Although each example of estimating natural long-termstream-temperature characteristics described belowwas selected for a stream having available stream-temperature data, similar procedures could be used toestimate temperature characteristics at ungaged sites.Also, it is important to note that each example relies onhistorical data through no later than 1984 that may ormay not accurately reflect current or future stream-temperature conditions.

Panther Creek

The first example illustrates how a user cancompare station data with the statewide harmonicequation. Panther Creek near Toccoa (station02182000) has 75 temperature measurements madebetween 1959-74 (table 1). Harmonic coefficients andcurves computed from station data and from equations(3), (4), and (5) appear in figure 9. The drainage area ofthis station is 33 mi2, somewhat less than the 40 mi2

regression equation criteria. Nonetheless, coefficientsderived from observed data are very similar tocoefficients computed from the statewide harmonicequation (fig. 9). The two curves in figure 9 show thatnatural temperatures for i 959-74 averaged about 1 to 2C higher than temperatures computed by the statewideharmonic equation.

West Armuchee Creek

This example illustrates the use of nearby data toimprove temperature-characteristic estimates. WestArmuchee Creek near Subligna (station 02388000)appears in table 1 with harmonic coefficients and adrainage area of about 36 mi 2. The comparison of theharmonic coefficients from actual data and the statewideharmonic equation is shown in figure 10. The harmonicstream-temperature characteristics curves are about thesame, except for the period October through March

when the statewide harmonic equation yields about I to2 0 C lower values. Because of differences of severaldegrees in the two characteristic curves during the coldweather months, it is helpful to examine temperaturecharacteristics at other nearby stations. Stations02397500, 02398000, 03566800, and 03567340 arenearby stations within the same Valley and RidgeProvince (figs. 197, 199, 210, and 211), and all show asimilar deviation from the statewide harmonic equationduring the cooler months. Therefore, the data user mayconsider this characteristic to be a local anomaly forstations in nearby streams in the Valley and RidgeProvince. Better estimation of stream-temperaturecharacteristics may require adjusting the coefficientsfrom the statewide harmonic equation to more closelyreflect local conditions.

In general, when using data from nearby stations toimprove estimates of natural stream-temperaturecharacteristics, streams having similar flowcharacteristics should be selected. For example, withinthe Coosa River basin, stations from the Valley andRidge Province in the western part of the basin showdiffering low-flow characteristics than stations typicallyrepresentative of the Piedmont Province to the east.Therefore, some local variations in long-term stream-temperature characteristics within the Coosa River basincan be expected.

A leovy River

This example determines the long-term naturalstream-temperature characteristics for a site in thePiedmont Province-Alcovy River above Covington(station 02208450). A search of the USGS databaseyielded 27 stream-temperature measurements forAlcovy River above Covington from 1972-75.However, because of the short period of record,harmonic computations are not shown in table 1. (Adaily record station was maintained here for about 7years; the information is summarized in table 2.) Forthis station, the input variables for the statewideharmonic equation are as follows-latitude of about33.64 degrees (decimal notation); drainage area of about185 mi 2; and altitude of about 650 ft. Figure 11 showsthe 27 temperature measurements observed from 1972-75, plotted on the annual cycle with the statewideharmonic equation superimposed. The data fit theequation well; and therefore, the data user may bereasonably confident that the data from the short periodof record-about four years-is indicative of long-termnatural stream-temperature characteristics at the station.

Altamaha River

The Altamaha River near Gardi (station 02226010)in the Coastal Plain Province also was selected as anexample to estimate long-term natural stream-temperature characteristics. Following the proceduresoutlined above, the data user will recognize that the sitehas 113 recorded temperature measurements (table 1).To independently estimate the long-term natural stream-temperature characteristics at this station, aninterpolation of harmonic characteristics from a nearbyupstream station, Altamaha River at Doctortown (station02226000) and a nearby downstream station, AltamahaRiver at Everett City (station 02226160) is performedand shown in table 4.

The reach of the Altamaha River from Doctortownto Everett City does not have substantial tributary inflowor modifications that would significantly alter long-termthermal characteristics during the period selected foranalysis. Interpolated and observed values compare wellwith the harmonic mean coefficient, showing the largestdifference of 0.3 0 C between interpolated data(19.6 0 C) and computed from observed data (19.9 0 C)(table 4). The 1970-84 temperature data at thedownstream station, Altamaha River at Everett City(station 02226160), generates a slightly higher harmonicmean temperature than either the statewide harmonicequation for the Gardi station or the observed record atDoctortown. The interpolated harmonic meancoefficients (table 4) were averaged from the upstreamand downstream stations, rather than to more heavilyweight the coefficients from the closer upstream station.

Using the coefficients computed from observeddata as a basis, it appears that the interpolated examplefurnishes better estimates than those obtained from thestatewide harmonic equation. Comments concerningtributary inflow, analysis of the stream reach, andweighing effects of modification were included in theexample because each can be important to stream-temperature estimation within a stream reach.

SUMMARY OFSTREAM-TEMPERATURE

CHARACTERISTICSBY RIVER BASIN

Many Georgia streams have reaches wherestream-temperature characteristics are modified byhuman activities. For example, streams immediatelydownstream from reservoirs or outflows from power-generating facilities typically exhibit modified stream-temperature characteristics. Principal hydro-power andthermoelectric-generating facilities in Georgia areshown in figure 12 and listed in table 5. Similarly,stream reaches often are affected by urban runoff,waste water, and other discharges from largemunicipalities and industries. Cities and towns havingpopulations greater than 10,000 population accordingto the 1980 census (U.S. Department of Commerce,Bureau of Census, 1982) are shown in figure 13.Stream reaches receiving such discharges or runoff willexhibit modified stream-temperature characteristics,depending upon the distance downstream and relativeamount of discharge to the flow of the receiving stream.

Selected stations in Georgia having natural andmodified stream-temperature characteristics aresummarized by river basin and discussed in thefollowing sections. Graphical illustrations of harmonic-temperature characteristics computed from thestatewide harmonic equation for stations listed in table 1are shown in figures 14 through 211. Stream-temperature characteristics in modified streams aremore difficult to estimate than natural streamsbecause streamflow, chemical, and thermalcharacteristics are undergoing changes from human-induced activities. The following sections describingstreams by river basin are intended as an aid inestimating stream-temperature characteristics in naturaland modified reaches, emphasizing modified largerstream reaches.

Savannah River Basin

The Savannah River and its tributaries, theTugaloo and Chattooga Rivers, form the northeasternboundaries of the State of Georgia (fig. 1). The basindrains about 10,580 mi2 of Georgia, South Carolina,and North Carolina. Headwaters are in themountainous Blue Ridge Province and the principalflow is southeastward through the Piedmont andCoastal Plain Provinces.

Stream-temperature characteristics computedfrom observed data and from the statewide harmonicequation for estimating natural characteristics for 26stream-temperature stations within the basin are shownin figures 14-39. Stream-temperature characteristics forfive mainstem Savannah River stations are listed in table2 and individual annual harmonic graphs are included infigures 17, 19, 33, 34, and 39.

Hartwell Lake accounts for most of the modifiedstream-temperature characteristics observed atSavannah River near Iva, S.C. (station 02187500)(fig. 17). Compared to natural stream-temperaturecharacteristics computed from the statewide harmonicequation, the harmonic mean temperature is lowered byabout 2.8 0 C, the amplitude by about 4.9 o C, theharmonic maximum temperature by about 7.7 o C, thephase coefficient by about 0.64 radians (resulting in astream-temperature season lag of about one month), andthe harmonic minimum temperature raised by about2.1 0 C. The downstream Savannah River station nearCalhoun Falls, S.C. (station 02189000) (fig. 19), showssome recovery toward natural characteristics. Stream-temperature records of both mainstem stations-Savannah River at Iva, S.C. (station 02187500) andSavannah River near Calhoun Falls, S.C. (station02189000)-have historic value since both now areinundated by Lake Richard B. Russell Reservoir.

The next mainstem station downstream fromCalhoun Falls is Savannah River at Augusta (station02197000). The Savannah River at Augusta station isabout 50.3 river miles downstream of Thurmond Lakeand its record (1958-73) is indicative of the pre-RichardB. Russell Reservoir period through 1984. Aftercompletion of Richard B. Russell Reservoir in 1983,some changes in downstream temperaturecharacteristics are expected.

Several other stations in the Savannah River basinshow modified long-term stream-temperaturecharacteristics. Six upper Broad River tributary stationsand three mainstream Broad River stations-North ForkBroad River above Toccoa (station 02189050);Denmans Creek near Toccoa (station 02189100); NorthFork Broad River near Toccoa (station 02189500); BearCreek near Mize (station 02189600); North Fork BroadRiver near Lavonia (station 02190000) Toms Creek nearEastonollee (station 02190100); Toms Creek nearAvalon (station 02190200); Toms Creek near Martin(station 02190500); and North Fork Broad River nearCarnesville (station 02191000) show characteristics

typical of stations below small dams or systems of smalldams. For each station, the data tend to show higherstream temperatures, particularly in the warmer months,than would be expected from the statewide harmonicequation (figs. 20-28). This primarily is caused by thedischarge of warm water from the surface of smallimpoundments. Similar effects on long-term stream-temperature characteristics may result from farm pondsor small recreational lakes. The magnitude of the effectswill depend primarily on storage, stream discharge,nature of the system of impoundments, thermalstratification, location of impoundment discharge, andthe distance of the site below the damor dams.

Ogeechee River Basin

The Ogeechee River basin has a drainage area ofabout 4,690 mi2 and lies mostly within the Coastal PlainProvince, with relatively small headwaters in thePiedmont Province (fig. 1). The Ogeechee River basinlies south of the Savannah River basin and does notcontain either large reservoirs or urban areas.

The first station for which stream-temperaturecharacteristics are illustrated is the Ogeechee River atScarboro (station 02202000). This station is about mid-basin without nearby stations to compare observedstream-temperature data. Figure 40 showsthat observed stream temperatures of Ogeechee Riverat Scarboro plot about 1 to 2 0 C lower than thoseestimated by the statewide harmonic equation.

Annual long-term stream-temperaturecharacteristics for Ogeechee River at Oliver (station02202190) are shown in figure 41. Harmonic stream-temperature characteristics generated from observeddata agree with values from the statewide harmonicequation, except for the period October through March,where values are about 0.5 to 1.0 0 C lower.

Stream-temperature characteristics for the nextdownstream mainstem station, Ogeechee River nearEden (station 02202500), are shown in figure 42.Stream-temperature characteristics generated by theobserved data agree with values from the statewideharmonic equation.

The Canoochee River is a major tributary to theOgeechee River and drains about 1,400 mi 2. Naturalstream-temperature characteristics computed from thestatewide harmonic equation and characteristicscomputed from observed data for Canoochee River nearClaxton (station 02203000) and Canoochee River atFort Stewart (station 02203519 are shown in figures 43and 44).

South of the Ogeechee River basin, near theGeorgia coast and downstream of several small inlandstreams, lies the Newport River tidal estuaries. Long-term observed stream-temperature characteristics forPeacock Creek at McIntosh (station 02203559) areshown in figure 45. This station and six other nearbytidal stations-(02203566, 02203570, 02203574,02203578, 02203585, and 02203596), not shown inillustrations of this report-have substantially warmerstream temperatures year round than temperaturescomputed from the statewide harmonic equation.Observed harmonic-mean temperatures range fromabout 1.6 0 C warmer than computed data at PeacockCreek at McIntosh (station 02203559) to about 2.5 ° Cwarmer seaward at North Newport River at HalfmoonLanding (station 02203578). In the tidal reaches ofnearby estuaries, stream-temperature characteristics, asdepicted by the observed data, show an amplitude about1.1 to 1.9 0 C higher than values generated by thestatewide harmonic equation. The statewide harmonicequation was derived from inland stream-temperaturedata and should not be used to estimate temperaturecharacteristics of tidal waters.

Altamaha River Basin

Rapidly developing basins, such as those aroundthe Atlanta Metropolitan area, are likely to have long-term stream-temperature characteristics that vary fromthose estimated by the statewide harmonic equation.Within such a basin, the data user may need to considereffects of basin modifications to better estimate current,or future, stream-temperature characteristics.

The Altamaha River originates in the PiedmontProvince of northern Georgia (fig. 1). The Oconee andOcmulgee Rivers account for about 5,250 and 6,080mi2, respectively, of the Altamaha River's total 14,480mi2 drainage area. The Ocmulgee River headwatersinclude the Atlanta Metropolitan area and less denselypopulated areas to the east. Stream-temperature-characteristic curves for the upper Ocmulgee Riverbasin, including the South River basin, are shown infigures 46 through 51. Stream temperatures of the upperreaches of the South River are higher than predicted bythe statewide harmonic equation, probably because ofdischarge from nearby Atlanta and DeKalb County, Ga.,waste-water treatment facilities and other municipal andindustrial basin modifications that usually accompanydevelopment. The 1985 completion of the city ofAtlantas "Three Rivers Project" rerouted waste waterfrom the Chattahoochee River basin away from theupper reaches of the South River, and back into theChattahoochee River. Therefore, stream-temperaturecharacteristics subsequent to 1985 likely will change.

25

The Yellow and Alcovy River basins, in the easternpart of the upper Ocmulgee River basin are experiencingmore rapid development as the Atlanta Metropolitanarea continues to grow. Pre-1985 annual observedtemperatures match the statewide harmonic equationvalues well for the Yellow River near Snellville (station02206500), Yellow River at Conyers (station02207300), Yellow River near Covington (station02207500), Yellow River at Porterdale (station02207540), Yellow River near Stewart (station02208005), and Alcovy River at Newton FactoryBridge Road near Stewart (station 02209260) (figs.52-57) except during cooler months from aboutNovember through February, when plots show about1 o C lower temperatures.

The confluence of the South and Yellow Riversform the Ocmulgee River that is joined by the AlcovyRiver in the upper part of Lloyd Shoals Reservoir(Jackson Lake). The stream-temperature characteristicsof the Ocmulgee River near Jackson (station 02210500),about 1 mile downstream from Lake Jackson, are shownin figure 58. Annual harmonic characteristics are shownfor the Towaliga River near Jackson (station 02211300)(fig. 59), where stream temperatures are about 3 0 Clower than estimates from the statewide harmonicequation throughout the winter months. Downstream,the Ocmulgee River in the vicinity of Macon (stations02212950 and 02213000) (figs. 61 and 62) reflects theusual municipal and industrial modifications associatedwith a developed area. Upstream fossil-fuel plantslikely also contribute to the modified temperaturecharacteristics of these two Ocmulgee River stations.Observed data for the Ocmulgee River at Lumber City(02215500) (fig. 71) agrees with the estimated long-term natural stream-temperature characteristics derivedby the statewide harmonic equation.

Stream-temperature characteristics for fourstations in the upper Oconee River basin-Allen Creekat Talmo (station 02217000); Middle Oconee River nearAthens (station 02217500); North Oconee River atAthens (station 02217740); and Oconee River at BarnettShoals near Watkinsville (station 02218000)-areshown in figures 72, 73, 74, and 75, respectively.Observed data from all of these stations agreereasonably well with long-term natural stream-temperature characteristics estimated by the statewideharmonic equation.

Stream-temperature data shown for Oconee Rivernear Greensboro (station 02218500) primarily havehistoric utility because the stream reach now lies within

Lake Oconee, where storage began in 1979 (fig. 76).Sinclair Reservoir is downstream from Lake Oconee.Oconee River at Milledgeville (station 02223000) (fig.80) depicts annual temperature characteristics about 3.8river miles downstream of Sinclair Dam. The effects ofthe newer Lake Oconee upon the stream-temperaturecharacteristics of this station and the downstreamstations, Oconee River near Hardwick (station02223040) (fig. 81); Oconee River near Toomsboro(station 02223250) (fig. 82); Oconee River at Dublin(station 02223500) (fig. 84); and Oconee River nearDublin (station 02223600) (fig. 85) are unknown.However, the latter two stations in the vicinity ofDublin show little effect because of the distancedownstream and the increased streamflow from thelarger drainage area.

Stream-temperature characteristics of themainstem Altamaha River are regarded mostly asnatural. The records for the Altamaha River stations atBaxley (station 02225000) (fig. 87), Jesup (station02225990) (fig. 90), Doctortown (station 02226000)(fig. 91), Gardi (station 02226010) (fig. 92), and EverettCity (station 02226160) (fig. 94) show that temperaturesfor June through September have maximums in the 29 to32 0 C range. Seasonal natural maximum temperaturesin these temperature ranges are corroborated by thestatewide harmonic equation.

Satilla River-St Marys River Basins

The Satilla and St Marys River basins (fig. 1) lie inthe Coastal Plain Province and drain about 4,380 mi2 insouthern Georgia and about 1,150 mi2 in northeasternFlorida. The Satilla River basin covers most of the area,encompassing about 3,530 mi 2 . Both basins have verylow relief, with headwater altitudes for the Satilla Riverat about 350 feet and St Marys River at about 120 feet.The Satilla River basin, like the nearby Altamaha Riverbasin, is characterized by high summer temperatureshaving observed maximum temperatures in the 29 0 to34 ° C range.

Long-term stream-temperature characteristics ofsix stations in the Satilla River basin are shown infigures 95-100. Two of the six stations, Satilla Rivernear Waycross (station 02226500) (fig. 96) and SatillaRiver at Atkinson (station 02228000) (fig. 100), showdeviation of observed data from the statewide harmonicequation. The estimated natural harmonic-meantemperatures for both stations are about 0.9 0 C lowerthan the harmonic mean indicated by observed data.

26

Suwannee-Ochlockonee River Basins

Principal streams in the Suwannee River andOchlockonee River basins in Georgia are theWithlacoochee, Alapaha, Suwannee and OchlockoneeRivers (fig. 1). The Suwannee and Ochlockonee Riverbasins cover south-central Georgia and north-centralFlorida and are about equally divided between the twoStates. The Okefenokee Swamp is in the headwaters ofthe Suwannee River and covers about 1,100 mi2 of theeastern end of the basin at an altitude of about 120 feet.The Suwannee River flows southward and thenwestward into the Gulf of Mexico. The headwaters ofboth the Withlacoochee and Alapaha Rivers are in thenorthern end of the basin with altitudes at about 450 ft.

Long-term harmonic characteristics are shownfor 12 stations in the Suwannee River basin (figs. 101-112). The harmonic-mean stream temperaturecomputed from observed data for Suwannee River atFargo (station 02314500) (fig. 101) is about 0.6 0 Chigher than the value computed from the statewideharmonic equation. This station includes the drainageof much of the Okefenokee Swamp which may accountfor the slightly higher stream-temperaturecharacteristics. As in the adjacent Satilla River basin,summer temperatures are high, with observedtemperatures as high as 31 o C, and wintertemperatures vary widely from 4 to 21 o C.

Four Ochlockonee River basin stations-Ochlockonee River near Moultrie (station 02327205);Ochlockonee River near Thomasville (station02327500); Tired Creek near Cairo (station 02328000);and Ochlockonee River near Calvary (station02328200)-are shown in figures 113-116. Theharmonic stream-temperature coefficients computedfrom observed data closely match those from thestatewide harmonic equation except for OchlockoneeRiver near Calvary (station 02328200) (fig. 116), whichplots about 1.4 ° C lower than the curve formed by thestatewide equation. However, the Ochlockonee Rivernear Calvary station data spans only the 1974-84period. Values computed from the statewide harmonicequation agree well with those values computed fromobservations for Ochlockonee River near Thomasville(station 02327500) (fig. 114) with data spanning theyears 1954-84. A reexamination of harmoniccoefficients for the Ochlockonee River nearThomasville station for the 1974-84 period (as was usedfor the Ochlockonee River near Calvary station)indicates that the harmonic mean for the Thomasvillestation also was about 0.9 0 C below the valuescomputed by the statewide harmonic equation.Therefore, observed temperature data for the 1974-84

period plotted below the statewide harmonic equation inboth instances.

Chattaho0chee River Basin

The Chattahoochee River basin extends from theBlue Ridge Province in northern Georgia to thesouthwestern tip of the State at the confluence with theFlint River (fig. 1). The basin drains about 8,770 mi2,

mostly in Georgia. The maximum width of the basin isabout 55 miles.

The Chattahoochee River system is the principalwater supply for about one half of Georgia's population(Marella and others, 1993). In addition, the river systemserves industry; provides recreation and fishing;generates power; assimilates wastes; and in the southernreaches of the river, supports shipping. Populationprojections for the upper Chattahoochee River basin,within the Piedmont Province, predict continuinggrowth (Brown, 1981).

Long-term observed stream-temperaturecharacteristics for stations within the ChattahoocheeRiver basin are shown in figures 117-145. Figures 117through 119 show temperature-characteristic curves forthree stations-Chattaho ochee River near Leaf(station 02331000); Chattahoochee River near Cornelia(station 02331600); and Chestatee River at StateHighway 52 near Dahlonega (station 02333500)-inthe upper part of the basin. Each of these three stationscompare well with curves computed from the statewideharmonic equation and shows mostly natural stream-temperature characteristics.

Stream-temperature characteristics forChattahoochee River near Buford (station 02334500),about 2.3 miles downstream from Lake Sidney Lanierare shown in figure 120. A harmonic-mean observedstream temperature of about 9.2 0 C is 6.1 0 C lowerthan the mean estimated by the statewide harmonicequation. In this reach of the Chattahoochee River,observed year-round temperatures are about the same asminimum winter temperatures estimated by thestatewide harmonic equation. These lower temperaturesoccur because of the dominant impact of storage of largevolumes of winter-season water in the large reservoir,Lake Sidney Lanier near Gainesville, Ga., formed byBuford Dam. Water from Lake Sidney Lanier isdischarged from depth, unlike surface-outlet structurescharacteristic of smaller ponds mentioned earlier. Aphase coefficient lag of 0.64 radians effectively shiftsthe stream-temperature season by about 37 days. Coolerthan natural stream temperatures also were observed atChattahoochee River near Norcross (station 02335000)(fig. 121), about 18 miles downstream from Lake Sidney

27

Lanier. Thirty-five stream-temperature measurementsduring May 1937 to December 1938 for theChattahoochee River at Atlanta (station 02336000) priorto the construction of Lake Sidney Lanier are shown infigure 123. Long-term stream-temperaturecharacteristic curves for Chattahoochee River at Atlanta(station 02336000) for the period after Lake SidneyLanier (1957-79) are shown in figure 124. AtChattahoochee River at Atlanta, summer temperaturesaverage about 6.0 ' C lower than computed naturalvalues. The station is located about 9.5 river milesdownstream from Morgan Falls Dam, a small 16.8kilowatt power-generation and river-regulation facility.

Harmonic stream-temperature characteristiccurves for Peachtree Creek at Atlanta (station02336300), are shown in figure 125. The PeachtreeCreek basin is totally within the Atlanta Metropolitanarea. Stream-temperature measurements at thisstation show summer maximum temperatures in the28 to 31 0 C range. The harmonic maximum for theobserved temperature data is about 26 0 C-about 3 ' Chigher than statewide harmonic equation values.Harmonic maximum stream temperatures of thismagnitude would normally be expected tooccur much farther south, indicating the effects ofurban development.

Stream-temperature characteristics atChattahoochee River at Interstate Highway 285 nearAtlanta (station 02336502) are shown in figure 126.Temperatures show a marked increase over values fromChattahoochee River at Atlanta (station 02336000)which is about 5.3 river miles upstream. The harmonic-mean temperature increase of about 2.6 0 C is caused, inpart, by the return of cooling water from electric-generating plants and from wastewater returns. Summertemperatures show more variability than natural, withsome measured values near 30.0 0 C, which is moretypical of a south Georgia stream. Also, as mentionedearlier, differing analysis periods (1957-79 forChattahoochee River at Atlanta) also could account forsome of the differences between the two stations.

Long-term stream temperatures for four tributarystreams-Sweetwater Creek near Austell (station02337000); North Fork Camp Creek at Atlanta(station 02337100); Dog River near Fairplay (station02337438); and Snake Creek near Whitesburg (station02337500)-are shown in figures 127, 128, 130, and131. Amplitude coefficients determined by observed

data for Sweetwater Creek near Austell (02337000) (fig.127) and Dog River near Fairplay (02337438) (fig. 130)are about 0.8 ° C above values predicted by the

statewide harmonic equation. Stream-temperaturecharacteristics from observed data for North Fork CampCreek at Atlanta (02337100) (fig. 128) show substantialdeparture from values calculated by the statewideharmonic equation. However, the drainage area ofNorth Fork Camp Creek at Atlanta is only 5.3 mi2 ; wellbelow the 20 mi 2 minimum drainage area recommendedfor use with the statewide harmonic equation.

Stream-temperature characteristics forChattahoochee River mainstem stations, ChattahoocheeRiver near Fairbum (station 02337170), Chattahoocheenear Whitesburg (station 02338000), andChattahoochee River at U.S. Highway 27 at Franklin(station 02338500) are shown in figures 129, 132, and133, respectively. Stream-temperature characteristicsfor Chattahoochee River at West Point (station02339500) are shown in figures 136 and 137. Thestation is about 3 miles downstream from West PointLake. Figure 136 depicts pre-West Point Lakeconditions and figure 137 represents post-West PointLake conditions. Stream-temperature characteristicsshow only a slight damping of post-Lake harmonicnatural amplitude from 9.2 to about 9.1 0 C. The mostapparent post-Lake difference is in the phase coefficientwhich changed from about 2.8 to about 2.6 radians or aseasonal lag of about 12 days.

Flint River Basin

The headwaters of the Flint River are located in thePiedmont Province of Georgia in the highly developedarea south of Atlanta (fig. 1). The basin hasa drainage area of about 8,460 mi2 and an averagewidth of about 40 miles.

Long-term annual harmonic stream-temperaturecharacteristics for stations in the Flint River basin areshown in figures 146-167; Harmonic mean andamplitude coefficients from the upper reaches of thebasin typically are about I to 2 0 C above valuescomputed from the statewide harmonic equation.This may be attributable to natural causes and effects ofdevelopment near the stations. Long-term stream-temperature characteristics for Flint River near Culloden(station 02347500) are shown in figure 154. At thisstation, the computed harmonic mean coefficient isabout 0.2 0 C higher and the amplitude coefficient isabout 0.8 0 C higher than values computed from thestatewide harmonic equation. Flint River near Cullodenwas among stations selected as mostly natural and it was

used to compute the statewide harmonic equation.

28

Downstream, Whitewater Creek belowRambulette Creek near Butler (station 02349000)(fig. 155) was selected as a natural stream-temperaturecharacteristics site. However, characteristics for thisstation generated by the statewide harmonic equationdiffer substantially from values shown by the moredamped actual-data curve. This damping primarily isdue to the large ground-water discharge to streamswithin the Whitewater Creek basin. For example,during extended low-flow periods, streamflows ofWhitewater Creek below Rambulette Creek near Butler(drainage area of 94 mi2) approach streamflows of themuch larger drainage area of the Flint River nearCulloden (1,850 mi 2). The data-derived harmonic-meancoefficient of 17.1 0 C is greater than the regionallycomputed harmonic mean of 16.6 ' C. A similar affect,but not as pronounced, of ground-water discharge tostreams also is seen in figure 157 for Turkey Creek atByromville (station 02349900).

Long-term annual harmonic stream-temperaturecharacteristics for the lower Flint River basin tributarystations are shown in figures 159, 163, 164, and 167.Data-derived harmonic curves agree well with thestatewide harmonic equation curves, except for PachitlaCreek near Edison (station 02353400) (fig. 163) andIchawaynochaway Creek at Milford (station 02353500)(fig. 164), where amplitude coefficients are damped byabout 0.9 0 C, possibly because of ground-water inflow.

Figures 162, 165, and 166 show annual harmoniccharacteristics of three lower mainstem Flint Riverstations: Flint River at Newton (station 02353000), FlintRiver at Bainbridge (station 02356000), and Flint Riverbelow State Docks at Bainbridge (station 02336015).The temperature characteristics of the latter two of thesestations may be somewhat affected by backwaters ofLake Seminole.

Coosa River Basin

The Coosa River basin covers about 4,360 mi2 ofValley and Ridge, Blue Ridge, and Piedmont Provincesin northwest Georgia (including a small part of southernTennessee) (fig. 1). The Coosa River is formed by theconfluence of the Oostanaula and Etowah Rivers(fig. 2). Streams in this basin serve many small towns;several hydropower and steam-power facilities; largeindustrial centers, such as the carpet industry at Dalton;and several medium-size towns, such as Rome.

Long-term annual stream-temperaturecharacteristics of headwater streams are shown infigures 168-170. For these stations, the statewideharmonic equation yields amplitudes from about 0.3 to0.9 0 C greater than those derived from data. Furtherdownstream, the records for the period 1965-72 for

Coosawattee River at Carters (station 02382500) (fig.172) and 1957-72 for Coosawattee River near PineChapel (station 02383500) (fig. 174) are prior to theimpoundment of Carters Lake; and therefore, primarilyhave historic utility. Modified stream-temperaturecharacteristics for Coosawattee River near Calhoun(station 02383540) for the post-Carters Lake period of1974-84 are shown in figure 175. Carters Lake and itsre-regulation dam cause a shift in the natural phase co-efficient that amounts to a seasonal lag of about 15 days.Also, the observed-data amplitude value of 8.8 ' C islower than the estimated natural value of about 9.6 ' C.

Stream-temperature characteristics for two smallCoosa River basin tributary streams-Scarecorn Creekat Hinton (station 02382000) and Rock Creek nearFairmont (station 02383000)-are shown in figures 171and 173, respectively. The harmonic-characteristiccurves for both stations average 1.0 to 1.5 0 C above thestatewide harmonic equation.

Annual temperature-characteristic curves forConasauga River near Dalton (station 02384748) andHolly Creek near Chatsworth (station 02385800) areshown in figures 176 and 177. Both stations areconsidered representative of mostly naturalconditions and are included in the stations used for thestatewide regression analyses (table 3). The harmonicmean and amplitude coefficients are about 0.5 0 Chigher than values computed from the statewideharmonic equation.

Annual stream-temperature characteristic curvesfor Conasauga River at Tilton (station 02387000) andConasauga River near Resaca (station 02387050) areshown in figures 178 and 179. Temperatures recorded atthe Tilton station likely are affected by industrial andland-use activities in the Dalton area. Naturaltemperatures for stations having similar basincharacteristics as the Tilton station typically occurfurther south. Downstream, at Conasauga River nearResaca (station 02387050) (fig. 179), harmonic-mean

and amplitude coefficients from observed data are about0.6 and 0.8 0 C higher than respective values generatedby the statewide harmonic equation.

In the vicinity of Resaca, Ga., the Conasauga andCoosawattee Rivers combine to form the OostanaulaRiver. The first Oostanaula River temperature stationdownstream of this confluence is the Oostanaula Riverat Resaca (station 02387500). The data andcharacteristic curves for this station are shown in figure180. The period of observed temperature data analysis(1957-72) preceded the construction of Carters Lake andwas included as one of the 78 statewide harmonicanalysis stations (table 3).

29

Harmonic curves for Oostanaula River at 1-75 atResaca (station 02387502) for the post-Carters Lakeperiod of 1974-84 are shown in figure 181. This stationis only a few miles downstream from the confluence ofthe Conasauga and Coosawattee Rivers. Streamtemperatures at Oostanaula River at 1-75 at Resaca moreclosely resemble the post-Carters Lake temperatures ofthe higher yielding Coosawattee River near Calhoun(fig. 175), with damped harmonic mean and amplitude,than those of the Conasauga River near Resaca(fig. 179).

Harmonic temperature curves computed fromobserved data and the statewide harmonic equation forWest Armuchee Creek near Subligna (station 02388000)are shown in figure 182. West Armuchee Creek nearSubligna has a small 36 mi2 drainage area. Duringwinter months, the observed-data curve is severaldegrees higher than the statewide harmonic equationcurve. This difference likely is attributable tosubstantial ground-water discharge, characteristic ofmany small streams within the Valley andRidge Province.

Figure 183 shows pre-Carters Lake data (1957-73)for Oostanaula River at Rome (station 02388500).Harmonic curves from the statewide harmonic equationand from the observed data are in close agreement withharmonic mean, amplitude, and phase coefficients,differing only by 0.3 0 C, 0.4 0 C, and 0.07 radians,respectively. The harmonic curve from the post-CartersLake period is shown for Oostanaula River (RomeIntake) at Rome (station 02388520) in figure 184.The only harmonic coefficient that shows a noticeabledifference from the statewide harmonic equation forthe period 1974-84 is the phase coefficient, with a lagof about 0.13 radians or about eight days.

Annual harmonic stream-temperaturecharacteristics for Etowah River near Dawsonville(station 02389000) are shown in figure 185. Theharmonic curve from the statewide harmonic equationplots about 1 ' C above the curve derived fromobserved data for January through July. This isconsistent with Etowah River near Canton (station02392000) shown in figure 187. For the Cantonstation, the 1 ° C cooler temperature is evident yearround. Both the Dawsonville and Canton stations areamong those selected to compute the statewideharmonic equation. Figure 186 shows stream-temperature data and characteristics for Shoal Creeknear Dawsonville (station 02389300). The observeddata for the Shoal Creek station shows a harmonicamplitude coefficient about 0.8 0 C lower than the

amplitude from the statewide harmonic equation.Figures 188 and 189 show the temperaturecharacteristics at Little River near Roswell (station02392500) for periods 1959-64 and 1964-75,respectively. The harmonic mean and amplitudecoefficients computed from the 1964-75 data are about1.5 0 C above respective values from 1959-64 and fromthe statewide harmonic equation. These differenceslikely are due to urban development, streamchannelization, and pond construction within the LittleRiver basin.

Computed annual stream-temperaturecharacteristics for Etowah River at Allatoona Damabove Cartersville (station 02394000) for a short pre-Allatoona Reservoir period are shown in figure 190.Allatoona Reservoir was completed in 1949 and islocated about 0.8 miles upstream from station02394000. Because the pre-Allatoona Reservoir record,shown in figure 190, continued only about one year(1938-39), no harmonic curve is shown for the data.Annual stream-temperature characteristics for the post-Allatoona Reservoir period (1958-84) are shown infigure 191. The more current record shows harmonicmean and amplitude coefficients both about 0.4 0 Clower and the phase coefficient about 0.42 radians lowerthan respective values of the statewide harmonicequation. The shift in phase coefficient amounts to aseasonal lag of about 24 days.

Harmonic characteristics for Etowah River aboveKingston (station 02394980), Etowah River nearKingston (station 02395000), and Etowah River atRome (station 02396000) are shown in figures 193, 194,and 195. Harmonic characteristics computed frommeasurements for these reaches of the Etowah Riverreflect the effects of reservoir, industrial, municipal, andfossil-fuel power-generation activities.

The Coosa River is formed by the confluence ofthe Oostanaula and Etowah Rivers in Rome, Ga. Figure196 shows stream-temperature characteristics for CoosaRiver near Rome (station 02397000) for the period1957-84. Harmonic coefficients computed from theperiodic stream-temperature measurements show abouta 0.6 0 C compression and a 0.16 radian (about 10 days)lag for the amplitude and phase coefficients,respectively, when compared with coefficients from thestatewide harmonic equation. Allatoona Dam on theEtowah River may be the principal cause of most ofthese differences.

Harmonic coefficients for tributary Cedar Creeknear Cedartown (station 02397500), Chattooga River atSummerville (station 02398000), and Chattooga River

30

at Chattoogaville (02398037) are shown in figures 197,199, and 200, respectively. The Cedartown,Summerville, and Chattoogaville stations all showhigher harmonic mean and lower amplitude coefficientsthan values estimated from the statewide harmonicequation. This may be caused by larger ground-waterdischarge to these streams.

Annual harmonic stream-temperaturecharacteristics for Coosa River (at the Georgia-AlabamaState line) near Coosa (station 02397530) for the period1974-84 are shown in figure 198. The harmonic curve,generated by the measured data, plots about 2 to 3 ' Chigher than the curve derived from the statewideharmonic equation throughout most of the year.Observed summer stream-temperature maximum andaverage values (harmonic mean values) at Coosa Rivernear Coosa are typical of streams much farther south.Elevated stream temperatures may be attributable toreturn flow from power generation at Plant Hammondand other industrial and municipal activities in thevicinity of Rome, Ga.

Tennessee River Basin

The Tennessee River basin (fig. 1) covers only afew square miles in northern Georgia. In general, theTennessee River basin streams in Georgia flownorthward to Tennessee; whereas, most other streams inthe State flow southward. Harmonic coefficientscomputed from periodic stream-temperaturemeasurements from the Tennessee River basin (fig. 1)are shown in figures 204-211. Tennessee River basinstations used to compute the statewide harmonicequation include Hiawassee River at Presley (station03545000) (fig. 204); Toccoa River near Dial (station03558000) (fig. 207); Fightingtown Creek atMcCaysville (station 0356000) (fig. 209); SouthChickamauga Creek at Graysville (station 03566800)(fig. 210); and West Chickamauga Creek near Lakeview(station 03567340) (fig. 211). Each of these curvesexcept Toccoa River near Dial have harmonic meantemperatures about 0.1 to 1.0 0 C higher and amplitudesabout 0.1 to 1.1 0 C lower than those computed by thestatewide harmonic equation.

Nottely River at Nottely Dam near Ivylog (station03553500) (fig. 206) and Toccoa River near Blue Ridge(03559000) (fig. 208) are immediately downstreamfrom impoundments and stream-temperature dataindicate modified characteristics. Both stations haveannual harmonic mean and amplitude coefficients about1 o C lower than values computed from the statewideharmonic equation. Phase coefficients for both stationsare about 2.1 radians, lagging the natural season byabout 41 days.

NWSRFS is our primary tool.

We do not use dynamic routing in our model of the lower Savannah River.

Routing Parameters in use at SERFC for Savannah River Basin

SERFC uses "Lag and K" routing.Lag and K routing by graphical methods is described inHydrology for Engineersby Linsley, Kohler, and Paulus2nd EditionChapter 7, Streamflow Routing.

Input to NWSRFS Lag/K Operation is described atwww.nws.noaa.gov/oh/hrl/nwsrfs/users-manual/part5/_pdf/5331agk.pdf

Sometimes we use a constant Lag and Ke.g. in segment HRTGIIN

Sometimes we use Lags and Ks that are afunction of dischargee.g. in segment JACS1.
