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

I. CONCLUSIONS
A. Trophic Condition:
Survey data indicate that John W. Flannagan Reservoir is
mesotrophic. It ranked first in overall trophic quality when the
eight Virginia lakes sampled in 1973 were compared using a com-
bination of six water quality parameters*. None of the other
lakes had less median total phosphorus, median dissolved phos-
phorus, and median inorganic nitrogen; one had less mean chloro-
phyll a_; and none of the others had greater mean Secchi disc
transparency. Marked depression of dissolved oxygen with depth
occurred at stations 1 and 2 in September.
Survey limnologists did not observe surface algae or emergent
vegetation.
B. Rate-Limiting Nutrient:
The algal assay results indicate that the reservoir was limited
by phosphorus at the time the sample was taken (04/05/73). The
lake data indicate phosphorus limitation at all sampling times.
C. Nutrient Controllability:
1. Point sources—During the sampling year, point sources
contributed an estimated 26.9% of the total phosphorus load to
John W. Flannagan Reservoir. The Clintwood wastewater treatment
plant contributed 13.1% of this input, and untreated wastes from
* See Appendix A.
-------
2
Pound accounted for 13.8%.
The present phosphorus loading of 2.47 g/m2/yr is more
than 1.5 times that proposed by Vollenweider (Vollenweider
and Dillon, 1974) as a eutrophic loading (see page 14).
Because the reservoir is limited by phosphorus and the loading
rate is high, all phosphorus inputs should be reduced to the
greatest practicable degree.
Water quality in the reservoir essentially is high as
has been noted in another report (Wollitz, 1973). However, if
phosphorus inputs continue at the existing rate, the reservoir
eventually will become eutrophic. Therefore, phosphorus removal
should be considered as a measure to prevent deterioration of
the present water quality.
Previous studies on the Pound River watershed have shown
that large amounts of waste from mines caused some of the tribu-
taries of this reservoir to become highly acidic (Wheeler et al.,
1970). Survey data indicate that the effect of such wastes on
the reservoir was minimal at the time the samples were taken.
Normal pH ranges were observed at all sampling stations.
2. Non-point sources—The phosphorus contribution of non-
point sources accounted for 72.4% of the load to the reservoir.
The Pound River contributed 22.2%, Cranesnest River contributed
23.3%, Holly Creek contributed 11.4%, and the remaining three
gaged tributaries collectively contributed 2.8% of the total.
-------
3
Ungaged tributaries were estimated to have contributed 12.7%.
The nutrient export rate of Holly Creek was very high (262
kg P/km2/yr) as compared to the rates of the other tributaries
in the reservoir watershed; e.g., Pound River (11 kg P/km2/yr),
Cranesnest River (15 kg P/km2/yr), Georges Fork (9 kg P km2/yr),
Bearpen Branch (8 kg P/km2/yr), and Cane Creek (9 kg P/km2/yr).
This may be indicative of other unknown point sources impacting
Holly Creek or underestimation of the phosphorus load coming from
the waste treatment plant at Clintwood. However, it is more likely
that the Holly Creek sampling station (C-l) was so close to the
Clintwood wastewater treatment plant that the effluent was not
completely mixed in the stream at the sampling point; note that
the mean total phosphorus concentration in Holly Creek was a very
high 1.422 mg/1, but the mean total phosphorus concentration in
Cranesnest River at station B-l was only 0.040 mg/1 (see map,
page v).

III. LAKE WATER QUALITY SUMMARY
John W. Flannagan Reservoir was sampled three times during the
open-water season of 1973 by means of a pontoon-equipped Huey heli-
copter. Each time, samples for physical and chemical parameters were
collected from a number of depths at four stations in April and Sep-
tember and three stations in July (see map, page v). During each
visit, a single depth-integrated (4.6 m to surface) sample was com-
posited from the stations for phytoplankton identification and enum-
eration; and during the first visit, two 18.9-liter depth-integrated
samples were composited for algal assays (stations 1 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 45.7 meters at station 1, 30.5 meters at
station 2, 30.5 meters at station 3, 12.2 meters at station 4, and 6.1
meters at station 5.
The sampling results are presented in full in Appendix D and are

2. Discussion -
The control yields of the assay alga, Selenastrum capri-
cornutum, indicate that the potential primary productivity
of John W. Flannagan Reservoir was low at the time the samples
were collected (04/05/73). Also, in both assays the signif-
icant increases in yields with the addition of orthophosphorus
alone indicate that this water body was limited by phosphorus
at that time. Note that the addition of only nitrogen resulted
in yields which were no different than those of the controls.
The reservoir data substantiate phosphorus limitation;
i.e., the mean inorganic nitrogen/orthophosphorus ratios were
22/1 or greater at all sampling stations and times, and phos-
phorus limitation would be expected.
-------
IV. NUTRIENT LOADINGS
(See Appendix E for data)
For the determination of nutrient loadings, the Virginia National
Guard collected monthly near-surface grab samples from each of the
tributary sites indicated on the maps (pages v and vi), except for the high
runoff month of February when two samples were collected. Sampling was
begun in July, 1973, and was completed in June, 1974.
Through an interagency agreement, stream flow estimates for the
year of sampling and a "normalized" or average year were provided by
the Virginia District Office of the U.S. Geological Survey for the
tributary sites nearest the lake.
In this report, 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.
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-2, B-l, D-l, E-l, and F-l
and multiplying the means by the ZZ area in km2.
The community of Clintwood did not participate in the Survey, and
nutrient loads were estimated at 1.134 kg P and 3.401 kg N/capita/year.
Nutrient loads from Pound, which had no treatment during the Survey
sampling year, were estimated at 1.587 kg P and 4.263 kg N/capita/year.

E. Yearly Loads:
In the following table, the existing phosphorus loadings
are compared to those proposed by Vollenweider (Vollenweider
and Dillon, 1974). Essentially, his "dangerous" loading is
one at which the receiving water would become eutrophic or
remain eutrophic; his "permissible" loading is that which
would result in the receiving water remaining oligotrophic
or becoming oligotrophic if morphometry permitted. A meso-
trophic loading 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.

* There was an apparent loss of nitrogen during the sampling year. This
may have been due to nitrogen fixation in the reservoir, solubilization
of previously sedimented nitrogen, recharge with nitrogen-rich ground
water, or unknown and unsampled point sources discharging directly to
the reservoir. Whatever the cause, a similar nitrogen loss has occurred
at Shagawa Lake, Minnesota, which has been intensively studied by EPA's
former National Eutrophication and Lake Restoration Branch (Malueg et al.,
1975).
