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.
-------
m
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

STORE! NO. 4221
I. CONCLUSIONS
A. Trophic Condition:
Survey data indicate that Lake Canadohta is eutrophic.
It ranked eighth in overall trophic quality when the 17
Pennsylvania lakes sampled in 1973 were compared using a
combination of six lake parameters**. Eight lakes had less
median total phosphorus, one had less and three had the same
median dissolved phosphorus, none had less and one had the
same median inorganic nitrogen, 13 had less mean chlorophyll
a^ and seven had greater mean Secchi disc transparency. Near
depletion of dissolved oxygen with depth occurred in July,
1973.
Survey limnologists reported higher aquatic plants along
the shore, but no algae blooms were evident.
B. Rate-Limiting Nutrient:
The algal assay results indicate that Lake Canadohta was
phosphorus limited at the time the sample was collected (04/20/73)
The lake data indicate phosphorus limitation in July as well but
nitrogen limitation in October.
* Table of metric conversions—Appendix A.
** See Appendix B.
-------
C. Nutrient Controllability:
1. Point sources—The estimated phosphorus load contributed
by the Canadohta Lake Park sewage treatment plant amounted to
2.8% of the total reaching Lake Canadohta during the sampling
year, and shoreline septic tanks were estimated to have contributed
nearly 26% of the total load. However, in a previous study, per-
sonnel of the Pennsylvania Department of Environmental Resources
found that many of the 500 or so septic tank systems were malfunc-
tioning (Boardman, 1975); and, in view of the lack of agreement
between the indicated trophic state and the relatively low phosphorus
loading rate, it is likely the estimated septic tank contribution
is too low.
The present phosphorus loading rate of 0.78 g/m2/yr is less
than that proposed by Vollenweider (Vollenweider and Dillon, 1974)
as a eutrophic rate but is more than his suggested oligotrophic
rate; i.e., is a mesotrophic rate (see page 13). Because Lake
Canadohta is phosphorus limited at least part of the time, and
because it is presently eutrophic, all phosphorus inputs to the
lake should be minimized to the greatest practicable extent to
slow the aging of this lake.
2. Non-point sources—Over 71% of the total phosphorus input
to Lake Canadohta was contributed by non-point sources during the
-------
sampling year. West Shreve Run accounted for 44.4%, East Shreve
Run contributed 18.5%, and the ungaged tributaries contributed an
estimated 6.5% of the total phosphorus load.
The phosphorus export rates of East Shreve Run and West
Shreve Run were relatively low (see page 12) and compare well
with the exports of the two tributaries of nearby Conneaut Lake*
(22 and 31 kg/km2/yr).

III. LAKE WATER QUALITY SUMMARY
Lake Canadohta 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 a
number of depths at a single station on the lake (see map, page v).
During each visit, a single depth-integrated (4.6 m to surface) sample
was collected for phytoplankton identification and enumeration; and a
similar sample was collected for chlorophyll a_ analysis. During the
first visit, a single 18.9-liter depth-integrated sample was taken for
algal assays. The maximum depth sampled was 5.2 meters.
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 Lake Canadohta was moderate at the time the sample was
collected (04/20/73). The addition of only phosphorus
produced a significant increase in yield, but no such in-
crease occurred with the addition of only nitrogen. There-
fore, limitation by phosphorus is indicated.
The lake data further substantiate phosphorus limitation
during April and July. The mean N/P ratios were 31/1 and
23/1, respectively. Limitation by nitrogen in October is
indicated by a mean N/P ratio of 8/1 .
-------
IV. NUTRIENT LOADINGS
(See Appendix E for data)
For the determination of nutrient loadings, the Pennsylvania
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 col-
lected. 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 Pennsylvania District Office of the U.S. Geological Survey for the
tributary sites nearest the lake.
In this report, nutrient loads for sampled tributaries were calcu-
lated using mean annual concentrations and mean annual flows. 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 B-l and C-l and multiply-
ing the means by the ZZ area in km2.
The operator of the Canadohta Lake Park wastewater treatment plant
did not participate in the Survey, and nutrient loads were estimated at
1.134 kg P and 3.401 kg N/capita/year.

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
Total Accumulated Total Accumulated
grams/mVyr 0.78 0.24 38.8 loss*
Vollenweider loading rates for phosphorus
(g/m2/yr) based on mean depth and mean
hydraulic retention time of Lake Canadohta:
"Dangerous" (eutrophic rate) 1.08
"Permissible" {oligotrophic rate) 0.54
* 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 and unsampled point sources discharging directly to the
lake, or underestimation of the nitrogen load from Canadohta Lake Park.
