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)], 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.

SMITH MOUNTAIN RESERVOIR
STORET NO. 5110
I. CONCLUSIONS
A. Trophic Condition:
Survey data indicate that the Roanoke River Arm of Smith
Mountain Reservoir is eutrophic, while the Blackwater River Arm
and the main body of the reservoir are mesotrophic. This has
also been concluded in previous studies on this water body
(Jennings et al., 1970; Simmons and Neff, 1969). Numerous
fish kills have been attributed to nutrient and organic enrich-
ment (Ketelle and Uttormark, 1971).
Of the eight Virginia water bodies sampled in 1975, Smith
Mountain Reservoir ranked third in overall trophic quality when
compared using a combination of six parameters*. Only one water
body had less median total and dissolved phosphorus, four had
less median inorganic nitrogen and mean chlorophyll a_, and only
one had greater mean Secchi disc transparency. Marked depression
of dissolved oxygen with depth occurred at stations 1, 3, 4,
and 5 in July and at all stations in September.
B. Rate-Limiting Nutrient:
The algal assay results indicate that Smith Mountain Reser-
voir was phosphorus limited at the time the assay sample was
collected (04/04/73). The reservoir data indicate phosphorus
limitation at the other sampling times as well.
* See Appendix A.
-------

C. Nutrient Controllability:
1. Point sources—The phosphorus load from point sources
accounted for 51.3% of the input to Smith Mountain Reservoir
during the sampling year. The Roanoke wastewater treatment plant
contributed 40.6%, and six other domestic treatment plants and
six industrial plants collectively contributed 10.7%. In
addition, several small municipal facilities, not included in
this report (see page 11), discharge to tributaries of the
Roanoke River. The loads from these sources probably would
increase the point-source contribution somewhat.
The present phosphorus loading of 2.23 g/m2/yr is over three
times that proposed by Vollenweider (Vollenweider and Dillon,
1974) as a eutrophic loading (see page 15). While even complete
removal of phosphorus at,the listed point sources would still
leave a loading about 1.7 times the eutrophic loading, the reser-
voir is phosphorus limited, and it is likely that a high degree
of phosphorus control at all point sources would at least result
in improvement in the presently eutrophic Roanoke River arm and
prolong the existing mesotrophic condition of the main body of
the reservoir.
2. Non-point sources—The phosphorus load from non-point
sources accounted for 48.6% of the total reaching the reservoir
during the sampling year. The gaged tributaries contributed a
total of 41.3% of the load and ranged from 18.1% (Roanoke River)
-------
3
to 0.1% (Kates Creek). The ungaged tributaries were estimated
to have contributed 6.5% of the total, and the pumped return flow
contributed 10.1%.
The mean phosphorus export rates of the Backwater River
(35 kg/km2/year), Gills Creek (41 kg/km2/year), and Beaverdam
Creek (33 kg/km2/yr) were somewhat higher than the rates of the
other tributaries in the drainage basin. This may be indicative
of unknown and unsampled point sources or may have been due to
land-use practices in those drainages.

III. LAKE WATER QUALITY SUMMARY
Smith Mountain Reservoir 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 reservoir 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 stations for phtyo-
plankton identification and enumeration; and during the first visit,
an 18.9-liter depth-integrated sample was composited from stations 1, 2,
3, and 4 and another such sample was taken at station 5 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
61.0 meters at station 1, 35.1 meters at station 2, 29.3 meters at station
3, 37.5 meters at station 4, and 23.2 meters at station 5.
The sampling results are presented in full in Appendix D and are
summarized in the following table.

Discussion -
The control yield of the assay alga, Selenastrum capri-
cornutum, indicates that the potential primary productivity
of Smith Mountain Reservoir was moderate at stations 1-4
but high at station 5. The results also indicate that the
reservoir was phosphorus limited at the time the samples
were collected (04/04/73). Note that with the addition of
nitrogen alone, the yield was not significantly different
from the control yield; however, with the addition of only
orthophosphorus, a significant increase in yield resulted.
The differences shown by the control yields at stations
1-4 and at station 5 indicate the difference in nutrient
availability. Note that the orthophosphorus concentration
-------
9
at station 5, nearest the domestic effluents, was twice
that at stations 1-4.
The reservoir data also indicate phosphorus limitation;
i.e., the mean inorganic nitrogen to orthophosphorus ratios
were 23 to 1 or greater at all sampling stations and times,
and phosphorus 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 map (page v), except for the high
runoff months of May and June 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*. The nutrient loads in the
pumped return flows from Leesvilie Reservoir (station AX; see Appendix
E) were determined by using the nutrient concentrations measured at
station AX and the daily flows measured at station A-l, assuming that
Smith Mountain Reservoir was maintained at a constant elevation (Anony-
mous, 1972). Nutrient loads shown are those measured minus point-source
loads, if any.
Nutrient loads for unsampled "minor tributaries and immediate
drainage" ("II" of U.S.G.S.) were estimated using the means of the
nutrient loads, in kg/km2/year, at stations B-l, E-l, F-'l, and G-l and
multiplying the means by the II area in km2.
* See Working Paper No. 175.

The operators of the Roanoke, Roanoke San. Corp. Starter Plant,
Vinton, and the Roanoke Nursing Home wastewater treatment plants
provided monthly effluent samples and corresponding flow data. The
operators of Botetourt Company Interchange San. Corp. and Roanoke
Co. P.S.A. North Ardmore Subdivision did not participate in the Survey,
and nutrient loads were estimated at 1.134 kg P and 3.401 kg N/capita/
year. The operator of the Lord Botetourt High School could not supply
flow data, and nutrient loads also were estimated.
In addition to the sources listed below, six small domestic facil-
ities, with a total design flow of 643.4 m3/day, discharge to tributaries
of the Roanoke River (Jennings et al., 1970). Nutrient loads from these
sources are included in the tributary loads.

2. Industrial -
Industrial point sources in the upper Roanoke River
watershed have an estimated design flow of less than 189.3
m3/day and include the Koppers Co., Inc.; Eaton Yale & Towne,
Inc.; Fuel Oil & Equipment Co.; Norfolk & Western RR Co.
Shaffer Crossing and East End Shops; and Roanoke Electric
Steel Co. (Jennings et al., op. cit.). These sources were
not sampled during the Survey year; however, in their 1971
study, Grizzard and Jennelle (1972) calculated that industrial
sources in the watershed contributed 15 kg total P and 91
kg Kjeldahl N per day. Nutrient loads attributed to industrial
sources in this report are based on these values.

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.
