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)L 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.
-------
iii
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.

LAKE BLACKSHEAR*
STORE! NO. 1302
I. CONCLUSIONS
A. Trophic Condition:
Survey data indicate that Lake Blackshear is eutrophic. It
ranked eighth in overall trophic quality when the 14 Georgia
lakes sampled in 1973 were compared using a combination of six
parameters. Eight of the lakes had less median total phosphorus,
11 had less median dissolved phosphorus, and nine had less median
inorganic nitrogen. While none of the lakes had less mean chloro-
phyll a_, all had greater mean Secchi disc transparency, and it is
. likely that the turbidity noted by Survey limnologists at all
sampling stations and times inhibited algal growth and resulted
in the relatively low chlorophyll a^ concentrations. However, the
Gum Creek embayment has a history of problem algal blooms (Anony-
mous, 1973a; Hall, 1975).
Lake Blackshear was not thermally stratified when sampled,
but dissolved oxygen was below saturation in all samples taken.
For example, in the shallowest samples analyzed for dissolved
oxygen (1.5 m), percent saturation ranged from 58 to 67 in June,
from 78 to 87 in September, and from 90 to 93 in November. In
the deeper samples, dissolved oxygen was as low as 42% of saturation.
* Table of metric conversions—Appendix A.
** See Appendix B.
-------
Lake Blackshear was drawn down about four meters and was
maintained at that level from August to early December for
tree removal (Hall, op. cit.). While the draw-down may have
influenced some of the parameters measured, there appears to
be little question as to the eutrophic nature of the lake.
B. Rate-Limiting Nutrient:
Results of the algal assay indicate that phosphorus was
limiting at the time of sample collection (06/22/73). The lake
data indicate phosphorus limitation in September as well but
nitrogen limitation in November.
C. Nutrient Controllability:
1. Point sources—The total phosphorus contributions of
the point sources within the 40-kilometer Survey limit*
amounted to 10.9% of the total load to Lake Blackshear during
the sampling year. The City of Cordele contributed 7.3% of
the total load; and the communities of Montezuma, Byronville,
Oglethorpe, and Vienna collectively contributed an estimated
2.8%.
The present loading rate of 9.78 g/m2/yr is nearly five
times that proposed by Vollenweider (Vollenweider and Dillon,
1974) as a eutrophic rate (see page 15). However, the mean
hydraulic retention time of Lake Blackshear at normal pool
* See Working Paper No. 175, "...Survey Methods, 1973-1976".
-------
level is a short 16 days, and Vollenwelder's model may not
apply. Nonetheless, the existing trophic condition of the
lake is evidence of excessive nutrient loads.
It is calculated that even complete removal of phosphorus
at the point sources noted above would only reduce the total
phosphorus load to Lake Blackshear by 10% and would reduce the
loading rate to 8.79 g/m2/yr. While institution of phosphorus
removal at the immediate sources should be the first step in
improving the trophic condition of the lake, particularly in
the Gum Creek embayment, it appears that a phosphorus control
program in the entire Flint River drainage basin upstream from
the lake is needed if a significant change in the trophic condi-
tion of the lake as a whole is to be accomplished.
2. Non-point sources—Nearly 90% of the total phosphorus
load reaching the lake during the sampling year is calculated to
have been contributed by non-point sources. The Flint River
contributed 83.8% of the total, and Gum Creek contributed 2.8%.
The remaining five gaged tributaries collectively contributed
about 2.5%.
During the sampling year, the phosphorus export rates of
the Flint River (32 kg/km2/yr), Gully Creek (41 kg/km2/yr), and
Gum Creek (48 kg/km2/yr) were appreciably higher than the mean
-------
of the export rates of the other four tributaries (14 kg/km2/yr;
see page 16).
The drainage area of the Flint River above Lake Blackshear
is nearly 9,000 km2 and there are point sources in the drainage
beyond the 40-kilometer limit of the Survey (Anonymous, 1972b);
e.g., the Atlanta Flint River and Clayton County wastewater
treatment plants (combined population equivalence of 90,000;
Anonymous, 1972a). These and other point sources contribute to
the Flint River phosphorus export and would require phosphorus
control as noted above.
The higher phosphorus export rate of Gum Creek may have
been due to occasional by-passing of sewage at the Cordele
wastewater treatment plant as is documented in a report by the
Georgia Department of Natural Resources (Anonymous, 1973a).
In that investigation, it was also found that areal drainage
from the Gold Kist Fertilizer Company plant site near Cordele
contained significant levels of phosphorus in the two samples
taken (3.3 mg/1 on June 28 and 1.4 mg/1 on August 30, 1973).
Drainage flows were not determined, however, and the magnitude
of this phosphorus contribution to Gum Creek is not known.
Gully Creek drains an area adjacent to the City of Cordele,
and the higher phosphorus export rate of this stream may be due
to urban contributions. However, nearby Cedar Creek, which
drains even more of the Cordele urban area, had a relatively
-------
low phosphorus export rate of 12 kg/km2/yr, so it seems likely
that the Gully Creek phosphorus load is due either to differences
in land-use practices, to point-source contributions, or both.

III. LAKE WATER QUALITY SUMMARY
Lake Blackshear 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 a number
of depths at four stations on the lake in the spring and summer and from
three stations in the fall (see map, page v). During each visit, a single
depth-integrated (4.6 m or near bottom to surface) sample was composited
from the four 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 10.7 meters at station 1, 10.7 meters at
station 2, 6.1 meters at station 3, and 3.7 meters at station 4. It is
noted that the lake was drawn down about four meters during the summer
and fall (Hall, 1975),
The results obtained are presented in full in Appendix D and sum-
marized in the following table.

3. Discussion -
The control yields of the assay alga, Selenastrum capri-
cornutum, indicate that the potential primary productivity
was low to moderate at the time the sample was taken (06/22/73).
The yield responses to increasing levels of phosphorus spikes
indicate that phosphorus was limiting. Note that there was
no change in yield when only nitrogen was added.
The lake data indicate phosphorus limitation during the
June and September sampling periods and nitrogen limitation
during the November sampling (i.e., the mean N/P ratios were
30/1 and 19/1 during the June and September sampling periods,
respectively, and 12/1 during the November sampling period).

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*. Stream 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 by using the means of the
nutrient loads, in kg/km2/year, at stations B-l, C-l, and D-l and
multiplying the means by the ZZ area in km2.
The operators of the Cordele and Montezuma #1 and #2 wastewater
treatment plants provided monthly effluent samples and corresponding
flow data. Nutrient loads from the villages of Byromville and Vienna
were estimated at 1.134 kg P and 3.401 kg N/capita/year. Nutrient

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 eutrophic
or remain eutrophic; his "permissible" rate is that which would
result in the receiving water remaining oligotrophic 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.
