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 [S303(c)3, 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
The staff of the National Eutrophication Survey (Office of
Research & Development, U. S. Environmental Protection Agency)

I. CONCLUSIONS
A. Trophic Condition:
Survey data indicate that Green!ane Reservoir is eutrophic.
It ranked last in overall trophic quality when the 17 Pennsylvania
lakes sampled in 1973 were compared using a combination of six
parameters**. Fifteen of the lakes had less median total and
dissolved phosphorus, 15 had less median inorganic nitrogen, 14
had less mean chlorophyll a_, and 13 had greater mean Secchi disc
transparency. Marked depression of dissolved oxygen with depth
occurred at stations 1 and 2 in July and October and at station
3 in July.
Survey limnologists noted an algal bloom in July and a heavy
bloom in the northern portion of the reservoir in October.
B. Rate-Limiting Nutrient:
The algal assay results indicate phosphorus limitation at the
time the sample was taken (04/17/73). The reservoir data indicate
phosphorus limitation at the other sampling times as well.
C. Nutrient Controllability:
1. Point sources—The phosphorus contribution from known
point sources amounted to 60.5£ of the total load reaching Green-
lane Reservoir during the sampling year. The known point sources
* Table of metric conversions—Appendix A.
** See Appendix B.
-------
include the Borough of Bally (1.5%), Candlewyck Inn (<0.1%),
Conte & Sons Packing Company (32.2%), East Greenville MWW
(5.4%), Hereford Estates (2.7%), Northeast Bible Institute
(0.1%), Pillsbury Company (1.5%), Upper Montgomery (16.6%),
and septic tanks, which include Knoll Industries, (0.1%).
The present phosphorus loading rate of 12.83 g/mz/yr is
11 times that proposed by Vollenweider (Vollenweider and Dillon,
1974) as a eutrophic rate (see page 15). On the basis of Survey
data, it is very likely that the trophic condition of Greenlane
Reservoir will continue to deteriorate if the present loading
rate is maintained.
Because of the existing trophic condition of the reservoir,
all phosphorus inputs should be minimized to the greatest practi-
cable extent to reduce the rate of eutrophication.
2. Non-point sources—The phosphorus contributions of non-
point sources accounted for nearly 40% of the total load reach-
ing the reservoir during the sampling year. The West Branch of
Perkiomen Creek contributed 12.5%, and Perkiomen Creek and the
ungaged drainage area were estimated to have contributed 21.5%
and 5.4% of the total load, respectively.
The phosphorus export rate of the West Branch of Perkiomen
Creek was 93 kg/km2/yr (see page 15). This rate is quite high
-------
compared to the exports of the two streams tributary to nearby
Beltzville Lake* (each with an export rate of 11 kg/km2/yr).
It is not known whether the high rate is due to underesti-
mation of the phosphorus load from the Borough of Bally waste-
water treatment plant or an unknown point source in the drainage.

III. LAKE WATER QUALITY SUMMARY
Greenlane 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 a number of 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
phytoplankton 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 18.9 meters at station 1, 10.4 meters at station 2,
and 4.9 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 Greenlane Reservoir was very high at the time the sample
was collected. There was a significant increase in yield
compared to the control when the level of orthophosphorus
was increased, but there was no change in yield when only
nitrogen was added. Based on these results, phosphorus
limitation is indicated.

The reservoir data indicate phosphorus limitation in
July and October as well; i.e., the mean N/P ratios were
43/1 and 29/1, respectively, and phosphorus limitation
would be expected.

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 vi), 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.
Except for phosphorus at station A-2, nutrient loads for sampled
tributaries were determined by using a modification of a U.S. Geological
Survey computer program for calculating stream loadings*. However, the
upstream point-source phosphorus loads exceeded the load measured at A-2,
and the non-point phosphorus load of Perkiomen Creek was estimated as
given below (it is assumed that all phosphorus loads eventually reach the
reservoir).
Nutrient loadings for Perkiomen Creek at A-2 and the unsampled "minor
tributaries and immediate drainage" ("ZZ" of U.S.G.S.) were estimated
using the nutrient loads (minus point-source loads), in kg/km2/yr, in the

West Branch of Perkiomen Creek at station B-l and multiplying by the
A-2 and ZZ areas in km2.
The operators of the Bally, Candlewyck Inn, Northeast Bible Insti-
tute, Pillsbury Company, and Upper Montgomery wastewater treatment
plants provided monthly effluent samples and corresponding flow data.
The operators of Conte & Sons Packing Company, East Greenville, and
Hereford Estates 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.
The operator of the Knoll Industries sanitary and industrial
wastewater treatment facilities also did not participate. Loads
attributed to the septic tank treating sanitary wastes were estimated
at 0.1134 kg P and 4.263 kg N/capita/year. Nutrient loads contributed
in the industrial wastes could not be determined due to insufficient
information.

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.
