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.
-------
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.

I. CONCLUSIONS
A. Trophic Condition:
Survey data indicate that Lake Tillery is eutrophic. How-
ever, because this lake has a hydraulic retention time of only
15 days, it more closely resembles a slow moving river; and
the term "over-enriched" may be a better description of the
condition of this water body.
Lake Tillery ranked eleventh in overall trophic quality
when the 16 North Carolina lakes sampled in 1973 were compared
using a combination of six parameters*. Nine of the lakes had
less median total phosphorus, seven had less and two had the
same median dissolved phosphorus, nine had less median inor-
ganic nitrogen, ten had less mean chlorophyll a_, and 13 had
greater Secchi disc transparency. Dissolved oxygen was depressed
with depth at all sampling stations in July, and percent of
saturation in the shallowest samples ranged from 53 to 70 in
September, except for station 2 where 99% of saturation
occurred.
Survey limnologists noted emergent vegetation along the
shorelines near stations 1 and 5. Phytoplankton numbers
* See Appendix A.
-------
increased significantly during the summer and fall, and blue-
green genera were dominant (see page 8).
B. Rate-Limiting Nutrient:
The algal assay results indicate that Lake Tillery was
phosphorus limited at the time the sample was collected. The
lake data indicate phosphorus limitation at all sampling times;
i.e., the mean inorganic nitrogen to orthophosphorus ratios
were 28 to 1 or greater.
C. Nutrient Controllability:
1. Point sources—During the sampling year, the phos-
phorus contribution of the two wastewater treatment plants at
Badin amounted to only 0.5% of the total load reaching Lake
Tillery.
The present phosphorus loading rate of 14.92 g/m2/yr is
over five times that proposed by Vollenweider (Vollenweider
and Dillon, 1974) as a eutrophic rate {see page 16); and, while
Vollenweider's model may not be applicable to water bodies with
short hydraulic retention times, the existing trophic condition
of Lake Tillery is evidence of excessive nutrient loads.
Control of phosphorus only at the Badin wastewater treatment
plants probably would have little effect on the trophic condition
of Lake Tillery. However, there are major point sources con-
tributing phosphorus to High Rock Lake* upstream in the Yadkin
* Working Paper No. 381.
-------
River drainage (see map, page v), and 1t 1s likely that a
significant portion of the phosphorus loads from these
sources impacted Lake Tlllery and Badin Lake* as well.
Considering only the phosphorus contributions of the
point sources Impacting High Rock Lake with the 40-kilometer
limit of the Survey**, the phosphorus retention 1n that lake
(54%), and the retention in intervening Badin Lake (ca. 22%),
it is calculated that 107,000 kg of the 298,000 kg point-source
load impacting High Rock Lake also affected Lake Tillery.
It is believed that a high degree of phosphorus control
at the major upstream point sources as well as at the immediate
point sources would result in a significant improvement in the
trophic condition of Lake Tillery, since the primary produc-
tivity of the lake is phosphorus limited.
2. Non-point sources—The Yadkln River contributed 92% of
the total phosphorus load reaching Lake Tillery during the
sampling year. However, on the basis of Survey data and other
studies (Anonymous, 1973), much of this load can be attributed
to the major upstream point sources as discussed above.
The phosphorus export rate of the Yadkin River was a
relatively low 27 kg/km2 during the sampling year (see page
15). Note, however, if the 107,000 kg of phosphorus calculated
* Working Paper No. 377.
** See Working Paper No. 175, "...Survey Methods, 1973-1976".
-------
to have been contributed by upstream point sources is sub-
tracted from the Yadkin River load at the Lake Tillery inlet,
the export rate is reduced to 17 kg/km2/yr. This rate is
quite comparable to that of the Uwharrie River which is not
impacted by point sources as far as is known.
Cedar Creek and Little Mountain Creek had phosphorus
export rates of 152 and 124 kg/km2/yr, respectively. These
rates are very high as compared to other Lake Tillery tribu-
taries and may be the result of urban drainage from the commun-
ities of Norwood and Badin.

III. LAKE WATER QUALITY SUMMARY
Lake Tillery 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
five 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, two 18.9-liter depth-integrated samples were composited for algal
assays (stations 1, 2, and 3 were combined, and stations 4 and 5 were
combined). Also each time, a depth-integrated sample was collected
from each of the stations for chlorophyll a_ analysis. The maximum
depths sampled were 20.7 meters at station 1, 13.7 meters at station 2,
14.6 meters at station 3, 10.7 meters at station 4, and 5.2 meters at
station 5.

2. Discussion -
The control yields of the assay alga, Selenastrutn capri-
cornutum, indicate that the potential primary productivity
of Lake Tillery was moderately high (stations 1, 2, and 3)
to high (stations 4 and 5) at the time the samples were
collected. Also, the increases in yield when orthophosphorus
was added, indicates limitation by phosphorus, although the
greatest increases occurred when nitrogen and phosphorus
were added together. Note that nitrogen alone did not
result in significantly increased yields in either assay.
The lake data further indicate phosphorus limitation.
At all sampling times and in both assay sample groups, the
mean inorganic nitrogen to orthophosphorus ratios were 28
to 1 or greater.

IV. NUTRIENT LOADINGS
(See Appendix E for data)
For the determination of nutrient loadings, the North Carolina
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 col-
lected. Sampling was begun in March, 1973, and was completed in Febru-
ary, 1974.
Through an interagency agreement, stream flow estimates for the
year of sampling and a "normalized" or average year were provided by
the North Carolina 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 exports, in kg/km2/year, at stations C-l, C-2, and D-l and
multiplying the means by the ZZ area in km2.
The operator of the Alcoa #1 (Badin) wastewater treatment plant
provided monthly effluent samples and corresponding flow data. The
operator of the Alcoa #2 (Badin) wastewater treatment plant also

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

Vollenweider loading rates for phosphorus
(g/m2/yr) based on mean depth and mean
hydraulic retention time of Lake Tillery:
"Dangerous" (eutrophic rate) 2.92
"Permissible" (oligotrophic rate) 1.46
* There was an apparent loss of nitrogen during the sampling year. This may
have been due to nitrogen fixation in the lake, solubilization of previously
sedimented nitrogen, recharge with nitrogen-rich ground water, unknown or
unsampled point sources directly impacting the lake, or insufficient outlet
sampling in relation to the short hydraulic retention time of the lake.
Whatever the cause, a similar loss of nitrogen has occurred at Shagawa Lake,
Minnesota, which has been intensively studied by EPA's National Eutrophica-
tion and Lake Restoration Branch (Malueg, et al., 1975).
