FOREWORD
The National Eutrophication Survey was initiated in 1972 in
response to an Administration commitment to investigate the nation-
wide threat of accelerated eutrophication to fresh water lakes and
reservoirs.
OBJECTIVES
The Survey was designed to develop, in conjunction with state
environmental agencies, information on nutrient sources, concentrations,
and impact on selected freshwater lakes as a basis for formulating
comprehensive and coordinated national, regional, and state management
practices relating to point-source discharge reduction and non-point
source pollution abatement in lake watersheds.
ANALYTIC APPROACH
The mathematical and statistical procedures selected for the
Survey's eutrophication analysis are based on related concepts that:
a. A generalized representation or model relating
sources, concentrations, and impacts can be constructed.
b. By applying measurements of relevant parameters
associated with lake degradation, the generalized model
can be transformed into an operational representation of
a lake, its drainage basin, and related nutrients.
c. With such a transformation, an assessment of the
potential for eutrophication control can be made.
LAKE ANALYSIS
In this report, the first stage of evaluation of lake and water-
shed data collected from the study lake and its drainage basin is
documented. The report is formatted to provide state environmental
agencies with specific information for basin planning [§303(e)], water
quality criteria/standards review [§303(c)], clean lakes [§314(a,b)],
and water quality monitoring [§106 and §305(b)] activities mandated
by the Federal Water Pollution Control Act Amendments of 1972.
-------
111
Beyond the single lake analysis, broader based correlations
between nutrient concentrations (and loading) and trophic condi-
tion are being made to advance the rationale and data base for
refinement of nutrient water quality criteria for the Nation's
fresh water lakes. Likewise, multivariate evaluations for the
relationships between land use, nutrient export, and trophic
condition, by lake class or use, are being developed to assist
in the formulation of planning guidelines and policies by EPA
and to augment plans implementation by the states.

I. CONCLUSIONS
A. Trophic Condition:
Survey data indicate that Jackson Lake is eutrophic and is
further deteriorating at a rapid rate as evidenced by the heavy
blue-green algal blooms that have occurred in the past three
years. Jackson Lake ranked thirteenth in overall trophic quality
when the 14 Georgia lakes sampled in 1973 were compared using a
combination of six parameters**. Twelve of the lakes had less
median total phosphorus, median dissolved phosphorus, median
inorganic nitrogen, and mean chlorophyll aj and 11 lakes had
greater mean Secchi disc transparency. Dissolved oxygen was
markedly depressed or even depleted in essentially all samples
taken at 4.6 meters and deeper.
Siltation is a serious problem in Jackson Lake, particularly
in the South River arm which is now so shallow that emergent
aquatic plants occur in that embayment (Hall, 1975).
B. Rate-Limiting Nutrient:
The algal assay results indicate that the lake was limited
by phosphorus at the time the sample was collected (07/01/73).
However, the lake data indicate the lake was nitrogen limited

-------
at one of the four sampling stations in July, at two of the
four stations in September, and at all four stations in
November.
C. Nutrient Controllability:
1. Point sourcesPoint-source contributions amounted to
66.4% of the total phosphorus input to Oackson Lake during the
Survey sampling year. This load was from 67 wastewater treat-
ment facilities discharging to the three major streams tributary
to the lake (Anonymous, 1972a). However, of the 67 plants, the
five major facilities serving the City of Atlanta and DeKalb
County and discharging to the South River accounted for 59.8% of
the total phosphorus input.
The present phosphorus loading rate of 33.38 g/m2/yr is 19
times that proposed by Vollenweider (Vollenweider and Dillon,
1974) as a eutrophic rate (see page 18).
The Georgia Water Quality Control Board has recently instituted
an effluent limit of 1 mg/1 total phosphorus at all major waste-
water treatment plants discharging to the South River (Herndon,
1975). On the basis of Survey data (Appendix E), it is calcu-
lated that meeting the effluent limit will require the following
levels of phosphorus removal at the five major plants:
Atlanta #1 =
#2 = 87%
#3 = 82%
DeKalb Co. #1 = 87%
#2 = 89%
-------
If the above percentages of phosphorus removal are attained,
it is calculated that the loading rate will be reduced to 16.23
g/m2/yr, and the total phosphorus input to Jackson Lake will be
reduced to 48.6% of the load measured during the sampling year.
That step should result in improvement in the trophic condition of
Jackson Lake, and the short 31-day hydraulic retention time of
the lake should facilitate rapid improvement in water quality.
A 100% reduction of phosphorus at all known point sources
would further reduce the loading rate to 11.21 g/m2/year. If
this can be accomplished without causing problems elsewhere, the
additional reduction would be highly desirable. In this regard,
it is noted that consideration has been given to diversion of the
wastewater now treated in the three Atlanta metro plants to other
Atlanta plants in the Chattahoochee River drainage (Franzmathes,
1974).
The diversion would reduce the phosphorus load to Jackson Lake
by 40% and result in at least some improvement in the trophic condi
tion of the lake. However, if the diverted wastes are not treated
to remove phosphorus, about 257,000 kg of phosphorus per year will
be added to an already excessive phosphorus load to West Point
Reservoir*, a new impoundment of the Chattahoochee River. Even
if an effluent limit of 1 mg/1 total phosphorus is applied to the
See Working Paper No. 282, "Report on Lake Harding".
-------
wastes diverted to the Chattahoochee River, it is calculated
that about 39,000 kg of phosphorus per year will be added to
the West Point Reservoir load. Since that load is already
excessive, any amount of added phosphorus will be too much;
and the trade-off would seem to be of questionable merit in
either case.
All of the five major wastewater treatment plants are located
more than 32 kilometers from Jackson Lake, and in estimating
the nutrient contributions from these sources, no allowance was
made for sedimentation of phosphorus or nitrogen into the stream
bed or assimilation by periphyton between the discharge points
and the lake. However, the relative concentrations of phosphorus
present in the South, Yellow, and Alcovy River during the Survey
sampling year indicate that the South River carried a much larger
load of total phosphorus - by a factor of nearly five and greater -
than did the other two rivers which received much smaller waste-
water inputs.
No direct estimates were made of the nutrient contribution
of storm-water runoff from Atlanta metropolitan areas which would
eventually reach Jackson Lake. However, nutrient loads at station
B-l would include this source and be reflected in the loading.
Weibel (1969) stated that "...urban storm-water runoff itself,
-------
without any sewage, may contain annually quantities of the same
contaminants, amounting to more than 3 percent of those of raw
sewage". A contribution of that magnitude would not change the
conclusion regarding the need for point-source phosphorus
control presented in this report.
A second consideration-regarding storm water drainage is
that phosphorus would be more likely to be bound to particulate
matter and therefore less available for algal assimilation,
whereas most of the phosphorus discharged from municipal treat-
ment facilities is in a soluble form.
2. Non-point sourcesThe phosphorus contribution of non-
point sources, including precipitation, amounted to 33.5% of
the total load during the sampling year. The South and Yellow
rivers contributed 25.6% and 5.8% of this load, respectively.
Collectively, the remaining three tributaries contributed 1.7%
of the total phosphorus input. Ungaged tributaries were estimated
to have contributed 0.3% of the total phosphorus load.
The South River had a phosphorus export rate of 117 kg/km2/
year (see page 18). This is very high compared to the other
Jackson Lake tributaries as well as some of the tributaries of
Allatoona Reservoir* and Lake Sidney Lanier**; e.g., Shoal Creek
(15 kg/km2/yr), Little River (39 kg/km2/yr), Chestatee River
(46 kg/km2/yr), and Wahoo Creek (60 kg/km2/yr). It is believed
this high export rate was due to urban drainage and the by-passing

III. LAKE WATER QUALITY SUMMARY
Jackson Lake was sampled three times during the open-water season
of 1973 by means of a pontoon-equipped Huey helicopter. Each time,
samples for physical and chemical parameters were collected from four
stations on the lake and from a number of depths at each station (see
map, page v). During each visit, a single depth-integrated (4.6 m or
near bottom to surface) sample was composited from the stations for
phytoplankton identification and enumeration; and during the first
visit, a single 18.9-liter depth-integrated sample was composited for
algal assays. Also each time, a depth-integrated sample was collected
from each of the stations for chlorophyll a_ analysis. The maximum
depths sampled were 26.8 meters at station 1, 10.4 meters at station 2,
4.6 meters at station 3, and 6.1 meters at station 4.
The results obtained are presented in full in Appendix D and are
summarized in the following table.

3. Discussion -
The control yields of the assay alga, Selenastrum capri-
cornutum, show that Jackson Lake is presently capable of
supporting high levels of primary production (18.8 mg/1 and
11.9 mg/1).
In the autoclaved-filtered sample, a significant increase
in yield did not result with the addition of nitrogen or
phosphorus alone, but the greatest yield occurred when nitro-
gen and phosphorus were added together.
In the filtered-only sample, a significant increase in
cell yield occurred when phosphorus alone was added; in other
words, a phosphorus-limited condition was demonstrated.
These algal assay data and the lake data indicate primary
production in Jackson Lake can be controlled by limiting phos-
phorus inputs.
-------
13
The lake data indicate a temporal and spatial combination
of limiting nutrients. It will be noted that the stations
nearest the point sources (stations 3 and 4; see map, page v)
tended to be nitrogen limited, while the stations further
away tended to be phosphorus limited.
Following is a tabulation of mean inorganic nitrogen
to orthophosphorus ratios for each of the stations and
sampling times with the indicated limiting nutrient in
parentheses.

Nitrogen limitation, as indicated by in-lake nitrogen to
phosphorus ratios, does not necessarily suggest that the
trophic condition of the lake can be improved by controlling
nitrogen inputs. The apparent condition of nitrogen-limitation
in Jackson Lake resulted from excessive point-source phosphorus
inputs to the South River arm (station 3), and to a lesser
extent, to the Alcovy River arm (station 4). The reversal
of the enriched condition, therefore, depends upon phosphorus
control, not nitrogen control.

IV. NUTRIENT LOADINGS
(See Appendix E for data)
For the determination of nutrient loadings, the Georgia National
Guard collected monthly near-surface grab samples from each of the
tributary sites indicated on the map (page v), except for the high
runoff months of January and February when two samples were collected.
Sampling was begun in March, 1973, and was completed in February, 1974,
Through an interagency agreement, stream flow estimates for the
year of sampling and a "normalized" or average year were provided by
the Georgia District Office of the U.S. Geological Survey for the
tributary sites nearest the lake.
In this report, nutrient loads for sampled tributaries were deter-
mined by using a modification of a U.S. Geological Survey computer
program for calculating stream loadings*. Nutrient loads shown are
those measured minus point-source loads, if any.
Nutrient loads for unsampled "minor tributaries and immediate
drainage" ("ZZ" of U.S.G.S.) were estimated using the means of the
nutrient loads, in kg/km2/year, at stations A-l and G-l and multi-
plying the means by the ZZ area in km2.
The operators of the DeKalb County #1 and #2; City of Atlanta #1,
#2, and #3; Covington; and Monroe wastewater treatment plants provided
monthly effluent samples and corresponding flow data.

E. Yearly Loading Rates:
In the following table, the existing phosphorus loading
rates are compared to those proposed by Vollenweider (Vollen-
weider and Dillon, 1974). Essentially, his "dangerous" rate
is the rate at which the receiving water would become eutro-
phic or remain eutrophic; his "permissible" rate is that
which would result in the receiving water remaining oligotro-
phic or becoming oligotrophic if morphometry permitted. A
mesotrophic rate would be considered one between "dangerous"
and "permissible".
Note that Vollenweider's model may not be applicable to
water bodies with short hydraulic retention times.
