FOREWORD
The National Eutrophi cation 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)3, clean lakes [§314(a,b)]s
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.

BLEWETT FALLS LAKE
STORE! NO. 3702
I. CONCLUSIONS
A. Trophic Condition:
Survey data show that Blewett Falls Lake is eutrophic.
However, since the lake has a mean hydraulic retention time
of only seven days, it more closely resembles a slow-moving
river; and the term "over-enriched" may be a more appropriate
description of the condition of this lake.
Blewett Falls Lake ranked thirteenth in overall trophic
condition when the 16 North Carolina lakes sampled in 1973
were compared using a combination of six parameters*. Thir-
teen lakes had less and one had the same median total phosphorus,
14 had less median dissolved phosphorus, 13 had less median
inorganic nitrogen, but only four lakes had less mean chlorophyll
a_. The relatively low concentrations of chlorophyll a_ and the
high nutrient levels indicate primary productivity may have
been light-limited. Fourteen of the lakes had greater mean
Secchi disc transparency, and Survey limnologists noted that
the lake was quite turbid at all sampling times. However, it
is likely that primary productivity would not be very high in
any case because of the very short hydraulic retention time
of the lake.
See Appendix A.
-------
Depression of dissolved oxygen with depth occurred at
sampling station 3 in July, and dissolved oxygen in tlie
shallowest samples collected in September did not exceed
77% of saturation.
Survey limnologists did not observe rooted aquatic
vegetation or concentrations of algae during their visits
to the lake.
B. Rate-Limiting Nutrient:
Because of a loss of nutrients in the assay sample from
the time of collection to the beginning of the assay, the
results are not representative of conditions in the lake at
the time the sample was taken (03/23/73).
The lake data indicate phosphorus limitation at all three
stations in March and July and at station 1 in September also.
However, nitrogen limitation is indicated at stations 2 and 3
in September.
C. Nutrient Controllability:
1. Point sources—The phosphorus contributions of the
listed point sources amounted to only 2.3% of the total load
to Blewett Falls Lake. However, there are at "least eight
municipal wastewater treatment plants in the Rocky River
drainage beyond the 40-kilometer limit of the Survey* (Anonymous,
See Working Paper No. 175, "...Survey Methods, 1973-1976".
-------
1971). These plants serve a combined 1970 population of
47,281 people.
Also there are major point sources in the Yadkin River
drainage upstream from Lake Tillery (Anonymous, 1973); and
during the sampling year, some 264,000 kg of total phosphorus
were exported from Lake Tillery to Blewett Falls Lake {see
Working Paper No. 390, "Report on Lake Tillery"). However,
the total phosphorus load measured in the Pee Dee River at
the inlet to Blewett Falls Lake, below the confluence of the
Rocky River, amounted to more than 900,000 kg during the
sampling year. If most of the difference is attributable to
the Rocky River phosphorus load, it appears that drainage
contributed on the order of 600,000 kg of total phosphorus
during the year. Considering the estimated 4,000 km2 drainage
area of the Rocky River, this phosphorus load seems quite high
{150 kg/km2), and a need for a more-detailed study of this
drainage and point sources is indicated.
The present Blewett Falls Lake phosphorus loading rate
of 91 g/m2/yr is 18 times that proposed by Vollenweider
(Vollenweider and Dillon, 1974) as a eutrophic rate (see
page 16). However, the mean hydraulic retention time of the
lake is a very short seven days, and it is probable that
Vollenweider's model is not applicable to this water body.
-------
As noted in the discussion of trophic condition, the
primary productivity of Blewett Falls Lake may have been
light-limited because of turbidity. If the turbidity observed
during Survey sampling is a persistent characteristic of this
lake, point-source phosphorus control would not be expected
to result in a significant improvement in the trophic condition-
However, if the turbidity is not a typical condition, every
effort should be made to minimize the phosphorus inputs to the
lake.
2. Non-point sources—The phosphorus export rate of the
Pee Dee River was nearly six times the mean of the rates of
the other Blewett Falls Lake tributaries (see page 16). This
high rate probably was due in large part to point-source inputs
in the Rocky River and Yadkin River drainages as noted above.

III. LAKE WATER QUALITY SUMMARY
Blewett Falls 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 one or more 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 three
stations for phytoplankton identification and enumeration; and during
the first visit, a single 18.9-liter depth-integrated sample was com-
posited 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 1.2 meters at station 1, 6.4 meters at
station 2, and 9.1 meters at station 3.
The lake sampling results are presented in full in Appendix D and
are summarized in the following table.

C. Limiting Nutrient Study:
A 30% loss of orthophosphorus and 61% loss of inorganic
nitrogen occurred in the assay sample between the time of
collection and the beginning of the assay, and the assay
results are not representative of conditions in the lake at
the time the sample was taken (03/23/73).
The lake data indicate phosphorus limitation at all three
sampling stations in March and July and at station 1 in Sep-
tember also (the mean inorganic nitrogen/orthophosphorus
ratios were 18/1 or greater). However, the data indicate
nitrogen limitation at stations 2 and 3 in September (the
mean N/P ratios were 4/1 and 9/1, respectively).

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 March,
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.
Except for Smith Creek, nutrient loads for sampled tributaries were
determined 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. However, the esti-
mated phosphorus load from Lilesville exceeded the load measured in
Smith Creek at station D-l, and the non-point nutrient contributions
of this stream were estimated.
Nutrient loads for Smith Creek and 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 B-l, C-l, G-l,
and H-l and multiplying the means by the Smith Creek and ZZ areas in
km2.
* See Working Paper No. 175.
-------
12
The operators of the Biscoe and Wadesboro wastewater treatment
plants provided monthly effluent samples and corresponding flow data
(the Wadesboro plant does not impact Blewett Falls Lake; however,
the analytical data are included in Appendix E for the record). The
operators of the Norwood, Mount Gilead, Ellerbe, Lilesville, Troy,
and Albemarle wastewater treatment plants did not participate in the
Survey, and nutrient loads were estimated at 1.134 kg P and 3.401 kg
N/capita/year.
Other wastewater treatment plants are located within the direct
drainage basin of the lake (see map, page v). Nutrient loads from
these plants were not determined since they are well beyond the 40-
kilometer limit of the Survey. Also, major point sources are located
in the Yadkin River drainage upstream from Lake Tillery which also
impact Blewett Falls Lake. The nutrient contributions of all of
these sources are included in the Pee Dee River loads measured at
station A-2, however.

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.
