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.
ACKNOWLEDGMENT
The staff of the National Eutrophication Survey (Office of
Research & Development, U. S. Environmental Protection Agency)
expresses sincere appreciation to the Ohio Environmental Protection
Agency for professional involvement, to the Ohio National Guard

I. CONCLUSIONS
A. Trophic Condition:
The Survey data indicate that Tappan Reservoir is eutrophic.
It ranked sixth in overall trophic quality when the 20 Ohio lakes
sampled in 1973 were compared using a combination of six parameters*.
Two lakes had less and one had the same median total phosphorus,
three had less median dissolved phosphorus, three had less median
inorganic nitrogen, ten had less mean chlorophyll a^, and six had
greater mean Secchi disc transparency. Dissolved oxygen was depleted
at the 6.4 meter depth at station 1 in July.
Survey limnologists reported surface algal blooms in July and
October.
B. Rate-Limiting Nutrient:
The algal assay results indicate that Tappan Reservoir was
phosphorus limited when the sample was collected (04/21/73). This
finding is substantiated by the lake data which show mean inorganic
nitrogen to orthophosphorus ratios of 23 to 1 or greater at all
sampling times.
C. Nutrient Controllability:
1. Point sources—The estimated total phosphorus contribution
from septic tanks amounted to 1.3/6 of the total load. The present
loading of 0.29 g/m2/yr is less than that proposed by Vollenweider
* See Appendix A.
-------
2
(Vollenweider and Dillon, 1974) as a eutrophic loading (see
page 11). Nonetheless, the reservoir 1s eutrophic, and phosphorus
inputs should be minimized to the greatest practicable degree.
2. Non-point sources—About 99% of the total annual phos-
phorus input to Tappan Reservoir is attributable to non-point
sources. Ungaged tributaries accounted for an estimated 44.3%
of the total input. The other non-point sources are Clear Fork
(23.1%), Standingstone Fork (20.2%), and Beaverdam Run (5.0%).
The phosphorus export rates of the sampled streams were quite
low during the Survey sampling year (see page 10) and compare
well with the mean export rate of the six Berlin Reservoir*
tributaries (26 g/km2/yr).

III. LAKE WATER QUALITY SUMMARY
Tappan 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 three
stations on the lake and from two 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 stations for phyto-
plankton 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 a_ analysis. The maximum depths sampled were 7.0
meters at station 1, 4.6 meters at station 2, and 1.8 meters at station 3.
The lake sampling results are presented in full in Appendix D and
are summarized in the following table.

2. Discussion -
The control yield of the assay alga, Selenastrum capri-
cornutum, indicates that the potential primary productivity
of Tappan Reservoir was moderate at the time the sample was
collected (04/21/73). The addition of phosphorus alone pro-
duced a significant increase in yield, whereas no such increase
was seen with the addition of nitrogen alone. Therefore,
phosphorus limitation is indicated.
The lake data substantiate this conclusion. At all
sampling times, the mean inorganic nitrogen to orthophosphorus
ratios were 23 to 1 or greater.

IV. NUTRIENT LOADINGS
(See Appendix E for data)
For the determination of nutrient loadings, the Ohio 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 February and March when two samples were collected.
Sampling was begun in May, 1973, and was completed in April, 1974.
Through an interagency agreement, stream flow estimates for the
year of sampling and a "normalized" or average year were provided by
the Ohio 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 loads, in kg/km2/year, at stations A-l, B-l, and D-l and
multiplying the means by the ZZ area in km2.
There are no known municipal waste treatment plants impacting
Tappan Reservoir.

E. Yearly Loadings:
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 oligo-
trophic if morphometry permitted. A mesotrophic 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.
Total Phosphorus Total Nitrogen
Total Accumulated Total Accumulated
grams/mVyr 0.29 loss* 9.3 loss*
Vollenweider phosphorus loadings
(g/m2/yi") based on mean depth and mean
hydraulic retention time of Tappan Reservoir:
"Dangerous" {eutrophic loading) 0.52
"Permissible" (oligotrophic loading) 0.26
* There was an apparent loss of nutrients during the sampling year. This may
have been due to nitrogen fixation in the lake, solubilization of previously
sedimented nutrients, recharge with nutrient-rich ground water, unknown and
unsampled point sources discharging directly to the lake, or underestimation
of the nutrient loads from ungaged tributaries. By trimming the August and
September total phosphorus concentrations at the outlet, which appear to be
higher than normal, the outlet phosphorus loading is reduced to 2,330 kg/yr
and a net accumulation of 1,080 kg/yr is seen. Doing the same for total
nitrogen gives outlet N of 85,250 kg/yr and net accumulation of 28,935 kg/yr.
