FOREWORD
The National Eutrophication Survey was initiated in 1972
in response to an Administration commitment to investigate the
nationwide threat of accelerated eutrophication to freshwater
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 nonpoint 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
watershed 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.
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
freshwater 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.
ACKNOWLEDGMENTS
The staff of the National Eutrophication Survey (Office of
Research and Development, U.S. Environmental Protection Agency)
expresses sincere appreciation to the Delaware Department of
Natural Resources and Environmental Control for professional
involvement and to the Delaware National Guard for conducting
the tributary sampling phase of the Survey.

I. CONCLUSIONS
A. Trophic Condition:
Kill en Pond is considered eutrophic based upon field
observations and analysis of Survey data. Algal blooms
were present during summer and fall sampling. Phytoplankton
genera identified were generally high pollution-tolerant
forms. Chlorophyll a^ levels were extremely high and
Secchi disc visibility was low. Primary productivity as
measured by algal assay control yield was high. Unstable
water levels and abundant emergent vegetation (spatterdock)
have been reported (Ketelle and Uttormark, 1971; Lesser,
1966).
B. Rate-Limiting Nutrient:
Algal assay results indicate that Killen Pond was
limited by available phosphorus levels. The ratios of
available nitrogen to orthophosphorus in sampled waters
indicate phosphorus limitation during spring and summer
sampling dates, but nitrogen limitation in the fall.
-------
C. Nutrient Controllability:
1. Point Sources - During the sampling year, the mean
annual phosphorus load from point sources was esti-
mated to be 52.2% of the total load reaching Kill en
Pond. The Swift Co. poultry processing plant con-
tributed 51.9% of the total load. The present
loading rate of 14.90 g P/m2/yr is about nine
times that proposed by Vollenweider (in press) as
"dangerous" (eutrophic) for a lake of such volume
and detention time. However, Vollenweider's model
may not apply to water bodies with short hydraulic
retention time and the mean hydraulic retention
time for Kill en Pond is only 8 days.
2. Nonpoint Sources - The mean annual phosphorus load
from nonpoint sources was 48.4% of the total load
reaching Killen Pond. The Murderkill River con-
tributed 40.5% and the remaining tributaries were
estimated to have contributed 7.0%.
Recommendations have been made for the construction
of a new water control structure on Kill en Pond (Ketelle
and Uttormark, 1971; Lesser, 1966). Stabilization of
water levels in the lake would curtail the growth of
spatterdock. Additional information concerning current
land uses is necessary before further recommendations
for lake improvements can be made.

II. LAKE AND DRAINAGE BASIN CHARACTERISTICS
Lake and drainage basin characteristics are itemized
below. Lake surface area, and mean and maximum depths
were provided by the State of Delaware; tributary flow data
were provided by the Delaware District Office of the
U.S. Geological Survey (USGS)(outlet drainage area includes
the lake surface area). Mean hydraulic retention time was
obtained by dividing the lake volume by mean flow of the
outlet. Precipitation values are estimated by methods as
outlined in National Eutrophication Survey (NES) Working
Paper No. 175. A table of metric/English conversions is
included as Appendix A.
A. Lake Morphometry:
1. Surface area: 0.30 km2.
2. Mean depth: 1.5 meters.
3. Maximum depth: 2.7 meters.
4. Volume: 0.450 x 106 m3.

III. LAKE WATER QUALITY SUMMARY
Kill en Pond 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 one station on the lake and from one or more
depths at each station (see map, page v). During each visit,
depth-integrated samples were collected from the station for
chlorophyll a_ analysis and phytoplankton identification and
enumeration. During the first visit, 18.9-liter depth-integrated
samples were composited for algal assays. Maximum depth sampled
was 1.2 meters at Station 1. For a more detailed explanation
of NES methods, see NES Working Paper No. 175.
The results obtained are presented in full in Appendix D
and are summarized in III A for waters at the surface and at
the maximum depth for each site. Results of the phytoplankton
counts and chlorophyll ^determinations are included in III B.
Results of the limiting nutrient study are presented in III C.

2. Discussion -
The control yield of the assay alga, Selenastrum
capricornutum. indicates that the potential primary
productivity in Killen Pond was extremely high at the
time the sample was collected. The increase in yield
with the addition of phosphorus as well as the lack
of increase when only nitrogen was added indicates
phosphorus limitation. Maximum growth response was
achieved with the simultaneous addition of nitrogen
and phosphorus.
The ratios of inorganic nitrogen to orthophosphorus
in the field samples for spring and summer were 42:1 and
37:1, respectively, indicating phosphorus limitation.
The nitrogen to phosphorus ratio for the fall sampling
data, however, was only 4:1, indicating nitrogen
limitation at that time.
-------
IV. NUTRIENT LOADINGS
(See Appendix E for data)
For the determination of nutrient loadings, the Delaware
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 April 1973
and was completed in March 1974.
Through an interagency agreement, stream flow estimates
for the year of sampling and a "normalized" or average year
were provided by the Delaware District Office of the USGS for
the tributary sites nearest the lake.
In this report, nutrient loads for sampled tributaries
were determined by using a modification of the USGS computer
program for calculating stream loadings. Nutrient loads
indicated for tributaries are those measured minus known
point source loads, if any.
Nutrient loadings for unsampled "minor tributaries and
immediate drainage" ("ZZ" of USGS) were estimated by using
the mean annual concentrations in Unnamed Tributary at
Station B(l) and mean annual ZZ flow.
The operators of the Felton (Lake Forest High School
and Swift Co.) wastewater treatmemt plant provided monthly
effluent samples and corresponding flow data.

E. Yearly Loading Rates:
In the following table, the existing phosphorus
loading rates are compared to those proposed by
Vollenweider (in press). Essentially, his "dangerous"
rate is the rate at which the receiving waters 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."
