INTRODUCTION
The U. S. Department of Agriculture, Soil Conservation Service (SCS),
plans to construct a multipurpose impoundment in southeastern Georgia
near the city of Claxton. At the request of and in support of SCS,
water quality studies were performed in the drainage basin of the pro-
posed Impoundment by personnel of the U. S. Environmental Protection Agency,
Region IV, Surveillance and Analysis Division (SAD). The studies were con-
ducted under a cooperative, cost reimbursable agreement between SAD and
SCS. A copy of this agreement [contracts No. Ag-13-SCS-00223 and No. Ag-
13-SCS-00226 (EPA-IAG-R-5-0604)] is enclosed as Appendix A.
PURPOSE
These studies were conducted to:
(1)	Determine and record preimpoundment water quality conditions
within the drainage basin of the proposed impoundment;
(2)	Provide a basis for predicting the water quality of the im-
pounded waters following project completion;
(3)	Provide data for the calibration and verification of the Hydro-
comp Simulation Programming (HSP) model which, if possible,
could then be used to predict future water quality in other
proposed impoundments. These predictions, it was anticipated,
could then be made with a minimal amount of additional data for
model calibration and only for impoundments in the same general
type of area (same climate, soil type and land usage). Unfor-
tunately, local variations proved too great to make this a re-
liable procedure.

-------
Authority
Authority for these studies may be found in the Federal Water
Pollution Control Act Amendments of 1972 [PL92-500, Sec. 104(b)(6)].

-------
SUMMARY
GENERAL
The proposed Cedar Creek Impoundment will be located in a primarily
rural agricultural section of southeast Georgia near the city of Claxton.
The multipurpose impoundment will have a normal pool area of 387 acres and
a 29,658 acre drainage basin. Natural conditions and both agricultural
and animal husbandry practices provide the only sources of pollution
in the drainage basin. When specific areas of the drainage basin are
considered, two stand out as major contributors of pollution with hea-
vier than normal loads from the above sources. These are the E-5 and
E-6 arms (drainage areas upstream of Stations E-5 and E-6).
STUDY FINDINGS
Ranges and Station Means
Water temperatures ranged from 16ฐ to 23ฐC in May and from 22ฐ to
26ฐC in August. A reevaluation excluding data from the E-5 and E-6 arms
showed little or no effect on these ranges.
Dissolved solids ranged from 8 to 3,120 mg/1 in May and from 4 to
2,202 mg/1 in August. Suspended solids ranged from 2 to 62 mg/1 in May
and from 1 to 22 mg/1 in August. Exclusion of data from the E-5 and
E-6 arms narrowed the range of the dissolved solids for August and the
range of the suspended solids for May.
pH ranged from 5.3 to 6.9 units in May and from 5.0 to 6.4 units in
August. Exclusion of pH data from the E-5 and E-6 arms had little or
no effect on the ranges.
3

-------
Dissolved oxygen (DO) ranged from 2.1 to 6.1 mg/1 in May and from
3.1 to 5.3 mg/1 in August. Exclusion of DO data from the E-5 and E-6
arms narrowed the ranges "by elevating the lower concentrations.
BOD5 ranged from 1.0 to 10.6 mg/1 in May and from 0.3 to 5.1 mg/1
in August. Exclusion of BOD^ data from the E-5 and E-6 arms narrowed the
ranges from both extremes.
Nutrient (nitrogen and phosphorus species) concentrations varied
widely, even within a given month. Exclusion of data from the E-5 and
E-6 arms caused only a slight reduction in the recalculated May (low flow)
average concentrations, but a large reduction in the August (high flow)
average concentrations. This indicates a large, runoff-oriented nutrient
contribution from these two areas.
Total organic carbon (TOC) ranged from 12 to 20 mg/1 in May and from
12 to 24 mg/1 in August. Exclusion of data from the E-5 and E-6 arms caused
a slight narrowing of the ranges.
Fecal coliform densities ranged from 130 to 5,600 counts/100 ml in
May and from 100 to 2,200 counts/100 ml in August. Exclusion of data from
the E-5 and E-6 arms had no effect on the May ranges; however, it narrowed
the August ranges by approximately fifty percent.
Salmonella were isolated at four of the five stations sampled for
this purpose in May.
Trends
High values (lows for DO) for nearly all parameters occurred during
August. Major exceptions were higher values in May for B0D5 and fecal
coliforms. Trends in Cedar Creek (upstream to downstream) include
slight reductions in both NO2 and NO^-N and Total-P concentrations and a
slight increase in fecal coliform densities.
4

-------
Data from Station E-4 on Cedar Creek (immediately downstream from
its confluence with the E-6 arm) exhibited a slight elevation of values
for almost all parameters.
Long Term BOD
During May, a long term BOD analysis was performed for Station E-l
to determine rate coefficients for mathematical modeling efforts. This
analysis yielded typical rate coefficients.
Animal Population-Distribution Study
This study, performed during Hay, demonstrated that the E-6, E-7,
and E-5, E-8 arms of the drainage basin contained the heaviest animal
population.
Time of Travel Study
This study, using dye tracer techniques, was performed only during
the low flow conditions which prevailed during May. Under these condi-
tions, the average stream velocity for Cedar Creek was 0.25 mph.
Diurnal Studies
These studies (November 1974 and January 1975) revealed no signi-
ficant diurnal variations.
Assessment of Potential Non—Point Source Loads
A gross non-point source assessment (see Appendix C) established
potential loads for typical conditions and evaluated the attenuation
effects of control practices. Numerical results of this assessment
are too voluminous to present in summarized form.
Hydrocomp Predictions
Postimpoundment water quality was predicted by the Hydrocomp simu-
lation Programming Model. The predicted water quality was compared to
Georgia water quality standards. No major problems with violation of
these standards were observed.
5

-------
Potential Problem Areas
Comparisons were made between different areas of the drainage basin
on a lbs/acre/day (combined chemical loadings) basis and on a fecal coliform/
acre/day (fecal coliform loadings) basis. These procedures flagged potential
pollution problems with discharges from the E-5 and E-6 arms. These same
types of comparisons, plus comparison on a total lbs/day (combined chemical
loadings) basis, showed that the E-6 arm held the greater potential for
pollution discharge problems. Comparison of the carbon—nitrogen ratios for
the two arms suggests that potential problems originating in the E-6 arm
will be more responsive to correction by control practices.
6

-------
CONCLUSIONS
(1)	The high fecal coliform densities encountered plus the Salmonella
isolations in the Cedar Creek watershed, represent storrawater runoff con-
ditions under free flowing stream conditions. After project completion,
retention time in the impoundment will cause a decrease in both fecal
coliform densities as well as the presence of Salmonella. These decreases
should be sufficient to make the waters acceptable for body contact recreation.
(2)	Increased residence time in the impoundment will tend to dampen water
quality variations now present in the free flowing stream. The occasional
high nutrient concentrations observed during this study will be more diluted
by the impoundment to levels acceptable for a variety of water uses. However,
persistence of high concentrations for an extended period of time may cause
a problem with algal production in the impoundment.
(3)	Potential problems in the E-6 arm of the drainage basin can be partial-
ly, if not completely, alleviated by improved domestic animal and fowl waste
handling practices.
(4)	The eutrophication potential for this impoundment will depend on con-
trol of nutrient sources. This control includes the capacity of swampy
areas to assimilate nutrients. The quantitative aspects of such a capacity
are not clearly understood. Qualitative aspects, however, are evidenced
by the data within this report.
7

-------
RECOMMENDATIONS
(1) Attempts should be made to arrive at an agreement with local landowners
(especially in the E-5 and E-6 arms of the drainage basin) for the following
purposes:
(a)	To contain runoff from swine and cattle feeding areas (especially
during recreational periods of the year);
(b)	To avoid more than the minimal application of chicken litter or
animal manure to drainage area soils (either as an agricultural
fertilizer or as a means of disposal) during recreational periods
of the year; and
(c)	To avoid the overapplication of chemical fertilizers.
(2) Initially, primary contact recreation in the upper reaches of the
impoundment, especially during heavy runoff periods, should be restricted.
Further fecal collform monitoring should be conducted after the impoundment
has stabilized. The absence of high fecal collform densities would warrant
a removal of this restriction.

Fecal coliform densities were determined using the membrane filter
technique as outlined in Standard Methods for the Examination of Water
and Wastewater, 13th Edition.
Qualitative determinations for the presence of Salmonella were made
at selected stations by filtering 200 ml of sample through a 0.45u membrane
filter. The filters were then placed in single strength Dulcitol Selenite
Broth. The inoculated enrichment broth was incubated for 18 to 24 hours

at 41.5ฐC according to Spino's procedure.
After primary enrichment, an inoculum was streaked onto Taylor XLD,
Agar (XLD), and Hektoen Enteric Agar (HE) plates and incubated for 18-24
hours. Suspected Salmonella colonies were picked from the respective
plates and identified by the scheme outlined in Table 3.

DESCRIPTION OF STUDY AREA
The heart of the Evans County Watershed project is a proposed multi-
purpose impoundment on Cedar Creek. This watershed7 is located on the
gently rolling Pleistocene shoreline of the Altanama Upland Division of
the coastal plain near Claxton in southeast Georgia. The impoundment is
to be located in Evans and Tatnall counties. The 46 square mile watershed
extends from Evans County across Tatnall County and into a small portion
of Candler County. The impoundment will cover 387 acres at normal (irri-
gation) pool level. Of these 387 acres, 272 acres will be available for
recreation usage. Maximum flood storage pool will be 635 acres.
Land usage is 35.3% cropland, 6.3% pasture, 49.5% forest, and 8.9%
idle or miscellaneous. Only a few concentrated sources of pollution exist;
these consist primarily of runoff from cattle pastures, swine feedlots, and
layer hen operations. Natural conditions and agricultural practices
create three possible non-point sources of pollution:
(1)	Stormwater and possibly irrigation runoff from a land surface
characterized by dendritic drainage patterns,
(2)	Subsurface discharge into stream channels from the shallow
groundwater table, and
(3)	Benthic decomposition of leaf and pasture litter deposited in
the streams, and from both living and dead bottom-dwelling or-
ganisms.
Land elevation in the study area ranges from 110 to 250 feet above
mean sea level (MSL). Base flows for the perennial streams in the area
average 0.6 cubic feet per second per square mile of drainage area.
During wet portions.of the year, the water table in this area is near
the surface, causing soil moisture values to approach saturation. At these
17

-------
times, even small amounts of rainfall cause Immediate runoff (either surface
or subsurface) and corresponding but slower increases in stream flow.
After extended dry periods, the water table is lowered sufficiently
to cause the smaller tributaries to become dry. The sandy soil becomes very
dry and capable of absorbing large quantities of rainfall without corres-
ponding increases in runoff and stream flow.
As examples, (Figure 2) a rainfall of less than 0.4 inches in August
(wet period) caused a stream flow increase of approximately 2.2 cfs with
less than one day's lag time (time between rainfall and peak stream flow).
During June (a dry period) a two inch rain caused approximately the same
river flow increase as was caused by the 0.4 inch rain in September. The
two-inch June rain, however, had a six day lag time. The hydrograph peaks
on May 8 and 13, and on August 11 and 18 (Figure 2) also demonstrate the
short lag time typical of wet periods.

STUDY FINDINGS
RANGES AND STATION MEANS
General
Extreme values (lows for dissolved oxygen and highs for most of
the other parameters) usually occurred at stations in the E-5 or E-6
arms of the drainage basin. These two potential problem areas include
Stations E-5 and E-8 and Stations E-6 and E-7 respectively. Analysis of
the data (Table 4) included two modes of comparison: (1) ranges of all
values and (2) ranges of station means, both with and without exclusion
of data from the E-5 and E-6 arms. These data were excluded to emphasize
the effects, or lack of effects, of these two arms on the overall ranges.
Where the overall ranges were significantly changed toward improved con-
ditions, environmental pollution from these arms is indicated for the para-
meter under consideration. This analysis included only data for May and
August, 1974. Data collected in November, 1974 and January, 1975 was only
from a few selected stations. The following discussion is based on the
analysis presented in Table 4.
Physical Parameters
A
Water temperature ranges were not appreciably changed by exclusion
of data from the E-5 and E-6 arms. The ranges reflect seasonal air tem-
peratures and to some extent, the shading effects of heavy summer and
fall vegetative cover (smaller ranges for August values).
* These ranges exclude a single high water temperature reading of 29.8ฐC,
which occurred at Station E-7 on May 13, 1974. Basin highs of 8.1 mg/1 dis-
solved oxygen (DO) and 10.6 mg/1 five-day biochemical oxygen demand (BOD^)
also occurred at this station on the same day. The excluded high temperature
value was considered atypical because of the circumstances surrounding collec-
tion of the sample. The sampling point was located on a small stream immediately
downstream of a very wide, shallow and slow-moving overflow from a small shallow
fish pond. The sample was collected late in the afternoon on a clear, unseason-
ably hot day.

Dissolved solids ranged from very low to very high during both the May
and August periods of comparison. Suspended solids remained low throughout
the year even after heavy areawide rains. This indicates that very little
sediment is transported from the relatively flat sandy fields to the streams.
In both modes of comparison, exclusion of solids data from the E—5 and E—6
arms lowered the August values for dissolved solids and the May values for
suspended solids. These exclusions did not appreciably change the values
for the May dissolved solids or the August suspended solids. This indicates
an occasional, but not consistent, effect of the E-5 and E—6 arms on these
parameters.
Chemical Parameters
All pH values were low. The magnitudes of these values for both modes
of comparison were not affected by exclusion of values from the E-5 and E-6
arms of the drainage basin.
Dissolved oxygen (DO) concentrations were variable. The steadily decrea-
sing May concentrations demonstrate the effects of the low to zero flow condi-
i
tions which prevailed on some of the smaller tributaries during that time. The
high of 8.1 mg/1 in May (see footnote in temperature discussion) possibly resulted
from algal oxygen production in the shallow pond. Exclusion of DO data from
the E-5 and E-6 arms narrowed the ranges in both modes of comparison, primarily
by elevating their lower extremes. This indicates that runoff from these two
arms is relatively low in DO.
Some of the five day biochemical oxygen demand (BOD,.) concentrations
were relatively high when compared with typical average BOD^ for free flow-
ing upland streams of 1-2 mg/1 and with typical slow flowing swamp water
streams of 2-3 mg/1. This holds true even when the single high BOD^ of
22

-------
10.6 mg/1 for May is excluded (see footnote in temperature discussion). This
is probably the result of domestic animal waste and decaying vegetation in
the low-lying swampy areas of the drainage basin. Exclusion of BOD^ data from
the E-5 and E-6 arms significantly reduced the upper limits of the recomputed
ranges in both modes of comparison. This indicates significant BOD^ contri-
bution from these two arms.
Concentrations of all of the nitrogen species studied and concentrations
of total phosphorus varied widely, even within a given month. The overall
effect of excluding values for the E-5 and E-6 arms was the lowering of the
upper limits of the ranges for both modes of comparison. Specifically, ex-
clusion had only a small effect on the May ranges for all values, and a
moderate effect on the ranges of station means. It did, however, have a
large effect in both modes of comparison for August. This suggests a large
nutrient contribution from the E-5 and E-6 arms.
Examination of the individual nitrogen parameters for May shows a
relatively large contribution from organic nitrogen (Org-N) to the total
Kjeldahl nitrogen (TKN) values and a smaller yet significant contribution
from ammonia nitrogen (NK^—N). These nitrogen contributions, plus the
fairly small concentrations of both nitrate-nitrite nitrogen (NO2+NO3-N)
and total phosphorus (Total-P) during the low flow conditions in May,
suggest that the largest part of the nutrient pollutional loadings during
drier periods of the year originates from decaying vegetation in the low-
lying swampy areas.
Examination of the same parameters for August shows a much higher TKN,
with the majority as NH3-N. Even though Org-N is the minority species in
this case, it still has a much higher concentration than in May. The high-
er August NH3-N concentrations coupled with the much higher NO2+NO3-N and
23

-------
total-P concentrations, plus much higher runoff-stream-flow conditions, sug
gests large nutrient contributions from animal sources during that month.
Total Organic Carbon (TOC) concentrations were typical for coastal
plain swampy areas and the ranges of data were small. Exclusion of data
for the E-5 and E-6 arms had no significant effect. There was very little
difference between the comparison periods.
Bacteriological Parameters
Fecal coliform densities were high and very variable during both study
periods with August having lower values for both modes of comparison. Exclu-
sion of values from the E-5 and E-6 arms during May had no effect on the
ranges of all data, but drastically reduced both the magnitude and range of
the station means. This exclusion for August lowered the upper values for
both modes of comparison. The E-5 and E-6 arms were significant contributors
of fecal coliforms.
The high fecal coliform densities represent stormwater runoff under free
flowing stream conditions. After project completion, retention time in the
impoundment will result in greatly reduced fecal coliform densities. No
water should be considered completely safe for body contact recreation, re-
gardless of its fecal coliform density. Some health risks will be involved
for the water user. However, these risks are greatly reduced in waters
with low fecal coliform densities.
Qualitative determinations to detect Salmonella were made at five stations
(E-l,E-3,E-4,E-9, and E-10) during May. Salmonella is a large serologically-
related genus comprised of over 1,300 serotypes. Salmonella is probably
the easiest enteric pathogen to isolate from water. All Salmonella are
considered pathogenic to man and animals.
The presence of Salmonella is proof of fecal contamination from either
man or animals, and establishes the potential of disease contraction resulting
24

-------
from water ingestion. It is important to note that the inverse of this
statement is not true. Failure to isolate Salmonella does not establish
that the water is free of pathogenic organisms.
The following serotypes were isolated during the May study:
Station No.	Serotype
E-l	Salmonella gaminara
E-4	Salmonella gaminara
Salmonella rubislaw
E—9	Salmonella rubislaw
E—10	Salmonella laviana
No serotypes were isolated at Station E-3. No Salmonella determina-
tions were made during the August study*
TRENDS
Table 5 shows that the high values (low values for DO) for most para-
meters during both May and August occurred on either the E-5 or E-6 arms of
the drainage basin (Stations E-5 and E-8, and Stations E-6 and E-7, respectively).
The predominance of mainstem (Cedar Creek) highs at Station E-4, immediately
downstream of confluence of the E-6 arm, demonstrates the effect of the E-6
arm on the mainstem.
In the majority of cases, August exhibited the highest station means.
The major exception to this was the occurrence of higher station means for
dissolved solids, suspended solids, BOD5, and fecal coliforms in May. Ex-
clusion of data from the E-5 and E-6 arms changes the comparison to show
August as the highest month for BOD5, but not for fecal coliforms. The
highest fecal coliform densities occurred during the drier period of the
year, both with and without inclusion of data from the E-5 and E-6 arms.
Highs for most of the chemical parameters occurred during the wet period. This

-------
apparent discrepancy in the data is understandable when the hydrogeological
characteristics of the area and the precipitation-hydrograph plots on Figure
2 are considered.
The flat fields and pastures in this area are composed of very permeable,
sandy soil underlain by a shallow ground water table. Chicken litter spread
on croplands and pastures, cow manure dropped on the pastures, and swine drop-
pings in feedlots would all decompose with some of the decomposition products
being leached into the soil following infrequent rains during drier periods.
Very little surface runoff would occur during these periods.
O
According to Davis and DeWiest , surface water runoff does not begin
until the amount of precipitation exceeds the infiltration capacity of the
soil. Part of the infiltration water will experience slow lateral flow above
the groundwater table toward nearby streams. The remainder will reach the
groundwater table and also flow very slowly toward the streams (groundwater
flow.) The rate of surface water flow, infiltration and both lateral and
groundwater flow to the streams, will depend on the grade of the terrain.
Additional factors affecting this rate include soil permeability as well as
both the slope and gradient of the groundwater table.
Material which leaches into the upper part of the soil column during
dry periods slowly migrates toward the streams. This material should reach
the streams fairly rapidly when the water table gradient is raised after
heavy rains. The concentration of material reaching the streams through
groundwater flow should undergo slow "tailing-off" as the accumulated material
is flushed from the groundwater.
On the other hand, some material will reach the streams by surface water
runoff after heavy rains. The rate of surface water flow to the streams will
27

-------
be slowed drastically by both the flat terrain and the woods and swampy
areas which border the streams in this area.
Fecal coliforms reach the streams mainly by surface water runoff.
Both increases and maxima for this parameter usually lag behind hydro-
9
graphic increases and maxima. The high mean fecal coliform counts en-
countered in May and the steady five day decrease in individual counts
(Appendix B) should, according to this argument, represent the declining
slope of a hydrograph. Reference to the May sampling period on Figure 2
shows this to indeed be the case. Figure 2 also shows that all August
sampling was performed during relatively low flows before and after hydro-
graphic maxima. This should and does indicate lower fecal coliform counts
than occurred immediately after the peak discharge.
Of the chemical parameters which show higher values in August, N02+
NOg-N is the most prominent (Table 5 - Monthly Comparative Means column).
These compounds leach through the soil much faster than any other chemical
parameter studied.10,11ป12	values for this parameter (Appendix
B) represent the final stages of groundwater flushing as shown by the "tail-
ing-off" of the long term hydrograph for April and May (Figure 2). The high
values for August, however, represent the initial portion of long-term
groundwater flushing after a long dry period of accumulation (Note on Fig-
ure 2 that rainfall in June and July had little or no effect on the low to
zero flow conditions).
The only upstream to downstream trends which occurred on the mainstem
(Cedar Creek) for any of the parameters were a slight reduction in NO2+NO3-N
and Total-P, and a slight increase in fecal coliform counts.
LONG TERM BOD
Long term BOD (1,4,5,7,10,12,14,16,18, and 20 day) analyses were
performed on a single sample collected from Station E-l on May 17, 1974.

ANIMAL POPULATION - DISTRIBUTION
During the week of May 13 through 17, 1974, animal population -
distribution data were gathered by a combined team of SAD and SCS person-
nel by interviewing the major farmers in the area. The results are pre-
sented in Table 6.
TIME OF TRAVEL STUDIES
Throughout the same week of May, time of travel studies were performed
by use of dye tracer techniques. Dye injections were made at Stations E-9
and E-3. The results of this study are presented in Table 7 and on Figure 3.
Figure 3 presents only the results of the dye injection at Station E-9. High
stream discharges which partially flooded the swampy areas, precluded time
of travel studies during August. This prevented comparisons between the
two study periods on a time of travel basis.

DIURNAL STUDIES
Diurnal studies were performed at Station E-l under ultra-low flow
conditions during November, 1974 and under peaking flood conditions during
January, 1975 (Figure 1). Results of these studies are presented in Ap-
pendix B. No significant diurnal variations were noted during either
period.

ASSESSMENT OF POTENTIAL NON-POINT SOURCE RUNOFF LOADS
The gross assessment performed for this drainage basin was accomplished
by applying loading factors to twelve sub-basins which are fully described
by land use, soil type, topographic features, livestock and poultry-popu-
lation-distributions and historic climatic conditions. A detailed report
of this procedure is given in Appendix C with applicable loading factors
stated. A brief summary of the results, both on an annual basis and on. the
seasonal wet period of June through August, follows:
•	The Cedar Creek drainage basin contains 29,658 acres and is
broken into 12 sub-basins ranging in size from 928 to 5,222 acres.
•	It undergoes an annual erosion of 99,039 tons and a wet period
erosion of 44,568 tons.
•	It has an annual sediment delivery of 16,958 tons and a wet
period sediment delivery of 7,631 tons.
•	A one"Inch per hour storm produces seven percent of the average
annual sediment load.
•	A two inch per hour storm produces thirty-two percent of the
*
average annual sediment load.
•	Livestock and poultry produce about three percent of the N,
two percent of the P, and 17 percent of the BOD.
•	Sediment contains about 85 percent of the N, 96 percent of the P, and
a negligible amount of BOD. This includes dissolved N and P.
•	Forest and pasture litter provide about twelve percent of the N,
two percent of the P, and 83 percent of the BOD.
* Under average soil moisture antecedent conditions
35

-------
The analysis was performed to establish potential loads for typical
conditions according to relationships stated on page "c" of the report.
Attenuation effects of control practices can be determined using these
calculations; however, it is unlikely that a valid comparison can be
made between stream loads based on sampling and these gross assessment
loads.

-------
HYDROCOMP WATER QUALITY PREDICTIONS14
General
The postimpoundment water quality of Cedar Creek was simulated
using the combined hydrologic and water quality models known as the Hydro-
comp Simulation Programming (HSP) model. The models were calibrated (or
adapted) to local conditions using observed hydrometeorologic and water
quality data collected by the Environmental Protection Agency. Water
quality in the basin was simulated for a five year period, both with and
without the proposed impoundment. The resulting time series of water
quality constituents was analyzed to determine the percentage of time that
various concentration levels would be exceeded both with and without the im-
poundment. The result of these analyses were compared with Georgia Water
Quality Standards.
Temperature
HSP predicts that the impoundment will dampen out extreme temperatures,
both on an annual and on a seasonal basis. Without the impoundment, viola-
tions of the Georgia water temperature standard of 32.2ฐC would occur ap-
proximately 0.4% of the time on an annual basis and one percent of the
time between June and September. With the impoundment, no violations are
predicted during any portion of the year.
Dissolved Oxygen
HSP predicted that the instantaneous minimum standard of 4.0 mg/1
D.O. would be violated less than two percent of the time on an annual basis,
with or without the impoundment. September is predicted to be the most
critical time of the year for the uncontrolled stream with violations 3.5%
of the time. Under impounded conditions, however, August is the most
37

-------
critical month, with violations predicted six percent of the time. Pre-
dicted violations are spread more uniformly throughout the year without
the impoundment (i.e., June-August with the impoundment, and June-March
without the impoundment).
Hydrocomp used a very high, possibly unrealistic, NH3 nitrification
rate coefficient of 0.1 per hour, rather than a more typical value such as
0.0185 per hour. Consequently, the simulated D.O. concentrations represent
the worst likely conditions; and actual D.O. concentrations may be consider-
ably higher than simulated.
Fecal Collform
HSP simulated both annual and summer fecal coliform concentrations,
both with and without the influence of the lake. The model results clearly
show that violation of Georgia's fecal coliform standard for body contact
recreation will not be a problem for the lake as a whole. In isolated
shoreline areas, where influent and impoundment waters are not well mixed,
problems could develop during some storm events. On an annual basis, pre-
dictions for the uncontrolled stream (for single observations, not for
samples) during some storm events, indicate counts greater than 200/100 ml
69 percent of the time, and greater than 2,500/100 ml one percent of the time.
Five Day Biochemical Oxygen Demand (BODO
Predictions for annual and seasonal BOD5 concentrations with and
without the impoundment were made. No appreciable variations were noted
on the seasonal basis. BOD5 concentrations of less than 5.0 mg/l are ex-
pected 95% of the time on the uncontrolled stream. With the impoundment,
values of less than 3.0 mg/l BOD5 were predicted 100% of the time
* Measured values not to exceed 200 organisms/100 ml based on a geometric
mean of four or more samples taken at least 24 hours apart.
38

-------
Occational high BOD,, values (greater than 9.5 mg/1 one percent of the time)
were predicted in the free-flowing stream, but such occurrences are to be
expected with the animal population found in the watershed.
Nitrogen and Phosphorus Species
Predicted concentration frequencies for the various species are
presented on Figure 5. HSP made no predictions as to the eutrophication
potential which would exist at the various nutrient concentrations.
Total Dissolved Solids (TPS)
Hydrocomp predicted that the impoundment would increase the TDS
concentrations slightly above those of the uncontrolled stream (greater
than 90 mg/1 100% of the time with the impoundment and 90% of the time
without the impoundment). However, peak concentrations would occur in
the free flowing environment (greater than 105 mg/1 two percent of the
time without the impoundment and never exceeding 100 mg/1 with the impound-
ment) .

POTENTIAL PROBLEM AREAS
Although the Hydrocomp Simulation Programming (HSP) Model"^ pre-
dicts no significant violation of Georgia's Water Quality Standards for
the Cedar Creek Impoundment as a whole, potential localized problems may
be prevented by control of non-point pollution sources in some areas.
Below is a more detailed examination of the two potential problem areas
previously discussed in the study findings (E-5 and E-6 arms).
For comparison purposes, the overall drainage basin was divided
into the following combined sub-basins with the indicated areas:
Combined Sub-basin	Upstream Area
E-6. E-7*	3.60 mi.2 (2,304 acres)
E-5, E-8*	9.22 mi.2 (5,901 acres)
E-9, E-10, E-ll, E-12*	19.89 mi.2 (12,729 acres)
v
Overall Basin
E-l through E-12	46.34 mi.2 (29,658 acres)
In order to establish the relative magnitude of potential pollutional
problems from a given sub—basin area, the sub-basins are compared to one
another and to the overall basin. Detailed comparisons of the combined
loadings (total lbs/acre/day for six parameters - TOC, BOD^, Total-P,
Org-N, NHyN and N02+N03~N) and fecal coliforms/acre/day are presented on
Tables 8-12.
The intermittent occurrence of zero flow conditions in some sub-
basins (described below) prevented comparison of all sub-basins with the
overall basin for the same sampling periods.
* Hereafter called the E-6, E-5, and E-9 sub-basins, respectively.

Period of	Flow
Comparison	Comparison	Conditions
5/15-17/74	E-9 with E-l	"0" flow at E-6
8/29-30/74	E-5, E-6 with E-l	"0" flow at E-9
Both periods of comparison, however, represent the same types of
rainfall-streamflow conditions (short response time between rainfall in-
cidence and streamflow increase). See "Description of Study Area" (dis-
cussion of Figure 2) for details on this phenomenon.
Comparison of loadings (Tables 8-12) indicate the following:
(1)	The E-5, E-6 combined sub-basins are only 28% of the area
of the overall basin (Station E-l). Compared to the overall
basin, however, they contribute a 9.2 times higher combined
chemical loading (Table 8) and a 3.8 times higher fecal con-
form loading (Table 12).
(2)	The E-9 sub-basin contains only 43% of the overall basin area
but is 93% higher in combined loadings (Table 9) and 1.2 times
higher in fecal coliform loadings (Table 12) than the overall
basin.
(.3) The combined E-5, E-6 sub-basins contain only 64% of the E-9
sub-basin area, yet they contribute combined chemical loadings
averaging 21 times higher (Table 10), and coliform loadings
averaging 7.6 times higher (Table 12) than E-9.
(4) The E-6 sub-basin is only 39% as large as the E-5 sub-basin,
but averages both a 7.1 times higher combined chemical loading
contribution (Table 11) and a 1.5 times higher fecal coliform
loading contribution (Table 12) than E-5.
The combined E-5 and E-6 sub-basins clearly contribute a larger
amount of the pollutional load to the proposed Impoundment site than would
47

-------
be indicated by their size. Analysis of data from these two sub-basins
on a total pounds/day basis (Table 13) indicates the following:
(1)	The E-5 sub-basin contributes a higher TOC and Org-N
load,
(2)	Both sub-basins contribute approximately the same load
of BOD^, and
(3)	The E-6 sub-basin contributes a higher load of Total-P,
NH3-N, and N02+N03-N.
The above comparisons suggest plants (leaf litter) in the E-5
sub-basin and animal waste in the E-6 sub basin as the major sources of
pollution. The smaller E-6 sub-basin has 1.4 times as many cattle, 1.3
C
times as many swine, and 2.3 times as many poultry as E-5. Compared
to E-6, the E-5 sub-basin contains 2.6 times the total area, 2.6 times
the stream miles, twice the swampy area and 4.2 times the forest area.
The E-6 sub-basin has a much greater amount of animal and poultry waste
subject both to leaching to the groundwater and surface runoff. The
E-5 sub-basin, however, generates more leaf litter subject to aquatic
decay and transport.
In support of these conclusions, and in an effort to determine the
relative magnitude of the contribution from these two pollutional sources,
the following carbon-nitrogen ratios (C:N) were used as guides.
* The poultry population3"^ in the E-6 sub-basin consists of a single 40,000
to 50,000 layer hen operation located approximately 0.6 stream miles up-
stream of Station E-6. In this operation, the majority of the chicken
litter is spread on surrounding cropland with the remainder placed in a
small, shallow holding pond.

Realizing that the C:N values for leaf litter and animal or poultry
waste apply to fresh materials, and that those for the two sub-basins rep-
resent partially decomposed material from both sources, the correlations
between basin and source type are good.
These comparisons and correlations suggest that the pollutional
loadings contributed by the E-6 sub-basin will be responsive to improved
animal and poultry waste handling practices. The pollutional loadings
from the E-5 sub-basin, which appear to originate largely from natural
processes, are less subject to control.
* Includes a C:N of 5.1:1 for poultry.

SUMMARY
The attached amendment to our current Cooperative Agreement
with SCS is Intended to extend the agreement through the next
fiscal year. This will be adequate time to complete and termi-
nate the project and will allow us to take advantage of unused
funds (more then $11,000) committed to the project.
Approximately May 1, 1975, the SCS finalized a contract with
Hydrocomp, a private computer firm specializing in hydrology
and water quality, which will analyze and make detailed (hour-
by-hour) water quality projections from our field data. This
is to be a slvmonth contract, and, consequently, Hydrocomp will
not finish Its work until around November 1, 1975, after which
time we will need to use its findings and report as the major
components of a report from EPA to SCS.
We am currently using the reimbursable funds available through
this cooperative agreement primarily to hire students on the
"Stay-in-School" program to process data. (All field work has
been completed.) An extension of this agreement will allow us
to continue to use the funds remaining in the contrect for
student salaries and other project-related costs. This use of
these funds will not hinder other work in progrees or esslgned
end will also provide Region IV with some very useful weter
quality data and projection techniques that will be valuable in
connection with similar projects which we review for SCS through
the EIS process.
ACTIOS
Please sign the attached amendment to allow us to continue to
use SCS-designated funds during the next fiscal year. Please
sign the original and all four copies of the amendment and return
them to ae.

APPENDIX C
A GROSS ASSESSMENT OF CEDAR CREEK, GA, WATERSHED RURAL RUNOFF ANNUALLY,
WET SEASON AND UNDER SELECTED STORM CONDITIONS
This watershed has been subdivided Into twelve areas (See Map - Page B)
to allow reasonably detailed Information to be used on a geographic
basis. This representation seemed best for this particular watershed;
however, some watersheds can be*divided into contained areas based on
land use or equal slope percentages. The locally developed process
EFARRB, "Erosion, Sedimentation and Rural Runoff," is flexible enough
to handle any of these area representations. The descriptive informa-
tion for each area is stated on Page C. The summarization of total
area results for five periods or conditions can be found on Page D
with detailed reports numbered 1 through 5 cross-referenced in the
summary.
The principal soils in the area are: Tifton (K - .24), Fuquay (K - .20)
Cowarts (K - .32), Lakeland (K - .17), Waher (K - .28), Leefield (K - .20),
Kershaw (K ฆ .15), and Troup (K - .17). Slope percentages ranged from
0-3Z In the swamp areas to 0-12X in the highlands, and slope lengths
ranging from 100 to 400 feet were used.
Sediment Delivery Ratios of .05, .10, and .20 were used in various
parts of the watershed, and the local area estimate of 2,900 pounds
per year per acre of Forest/Pasture Litter-fall* was considered appropri-
ate. The ultimate delivery to waterbodies of nutrients from this
litter was estimated at 1%. Standard Cropping Factors (C) were used,
and no Control Practices (P) were assumed.
The calculating process for erosion is the "Universal Soil Loss Equation"
and specific values for Slope Z, Slope Length, R, K, C, and P can be
input to the system to give specific answers; however, Slope Z and Slope
length can be input as ranges and R, K, C, and P can be input as values
with percentage composition based on Land Use, and this results in a
variety of evaluations combining randomly selected components to more
accurately represent the variable nature of actual areas.
The results given on Page D represent the best assessment obtainable with
the knowledge available to the author; this final report represents use of
considerable localized information.
