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)j, 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.
-------
Ill
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.

BLUE RIDGE LAKE*
STOREY NO. 1316
I. CONCLUSIONS
A. Trophic Condition:
Survey data indicate that Blue Ridge Lake is early meso-
trophic. Blue Ridge Lake ranked first in overall trophic
quality when all 14 Georgia lakes sampled in 1973 were compared
using a relative index combining six parameters**. One lake had
less median total phosphorus, one had less and two had the same
median dissolved phosphorus, one had less median inorganic nitro-
gen, two had less mean chlorophyll a^, and two had greater mean
Secchi disc transparency.
Survey limnologists did not note any nuisance lake conditions
during sampling visits. However, oxygen depression occurred at
stations one and two, and oxygen depletion occurred at station
three during periods of thermal stratification.
B. Rate-Limiting Nutrient:
Algal assay results and lake data indicate phosphorus limi-
tation; i.e., the mean inorganic nitrogen to orthophosphorus
ratios were 21/1 or greater at all sampling times.
* Table of metric conversions—Appendix A.
** See Appendix B.
-------
C. Nutrient Controllability:
1. Point sources—There were no known municipal wastewater
treatment plants discharging to Blue Ridge Lake during the samp-
ling year. The Chattahoochee National Fish Hatchery discharges
to Rock Creek, a tributary of the Toccoa River; however, nutrient
contributions from this source are not known.
The present loading rate of 0.91 g/m2/yr is greater than the
rate proposed by Vollenweider (Vollenweider and Dillon, 1974) as
an oligotrophic rate but is less than his proposed eutrophic
rate; i.e., is a mesotrophic loading rate (see page 14). Unless
this loading rate is increased, the excellent trophic condition
of Blue Ridge Lake should be maintained.
2. Non-point sources--The Toccoa River accounted for almost
80% of the total phosphorus load reaching Blue Ridge Lake during
the sampling year. While this load includes phosphorus discharged
from the Chattahoochee National Fish Hatchery, the export rate of
21 kg/km2/yr does not appear to be unusual as compared to the
other tributaries of Blue Ridge Lake (see page 14) or the tribu-
taries of nearby Chatuge Lake* (mean = 22 kg/km2/yr) and Nottely
Reservoir** (mean = 20 kg/km2/yr). Also, in a recent Georgia
Department of Natural Resources report (Anonymous, 1973), the
* Working Paper No. 286.
** Working Paper No. 291.
-------
Toccoa River was classified as "healthy" at a sampling station
near the community of Dial about 12 stream miles below the
hatchery. Therefore, it does not appear that the hatchery is
a significant phosphorus source, although a more-detailed
study would be needed to determine this.
Wilscot Creek contributed 8.1% of the total phosphorus load,
and the remaining tributaries ranged from 1.2% to 1.6%. The
ungaged tributaries were estimated to have contributed 6.0%.

III. LAKE WATER QUALITY SUMMARY
Blue Ridge 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 three
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 to
surface) sample was composited from the three 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 ^analysis. The maximum depths sampled
were 43.0 meters at station 1, 32.3 meters at station 2, and 33.2 meters
at station 3.
The results obtained are presented in full in Appendix D and are
summarized in the following table.

2. Discussion -
The control yields of the assay alga, Selenastrum capri-
cornutum, indicate that the potential primary productivity
was low at the time the sample was collected. Although a
nitrogen loss occurred after the sample was collected, the
sample was still phosphorus limited (the inorganic nitrogen
to orthophosphorus ratio was slightly less than 14/1).
0
Consequently, when a phosphorus spike of 0.010 mg/1 was added,
the sample was shifted from phosphorus to nitrogen limited.
An increase in yield, therefore, did not occur until nitrogen
was added in combination with phosphorus. Productivity in
this situation could be decreased by reducing the phosphorus
concentration.
The lake data indicate phosphorus limitation at all samp-
ling times; i.e., the mean inorganic nitrogen to orthophosphorus
ratios were 21/1 or greater on all occasions.

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 by using the mean of the
nutrient loads, in kg/km2/year, at stations A-l, D-l, and E-l and
multiplying the means by the ZZ area in km2.

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.
Total Phosphorus Total Nitrogen
Total Accumulated Total Accumulated
grams/m2/yr 0.91 0.33 27.0 13.6
Vollenweider loading rates for phosphorus
(g/m2/yr) based on mean depth and mean
hydraulic retention time of Blue Ridge Lake:
"Dangerous" (eutrophic rate) 1.16
"Permissible" (oligotrophic rate) 0.58
