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 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 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
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.
ACKNOWLEDGMENT
The staff of the National Eutrophication Survey (Office of
Research & Development, U. S. Environmental Protection Agency)
expresses sincere appreciation to the North Dakota State Depart-
ment of Health for professional involvement, to the North Dakota
National Guard for conducting the tributary sampling phase of the
Survey, and to those North Dakota wastewater treatment plant oper-
ators who voluntarily provided effluent samples and flow data.
Norman L. Peterson, Director, and the staff of the Division
of Water Supply and Pollution Control of the Department of Health,
provided invaluable lake documentation and counsel during the
Survey, reviewed the preliminary reports, and provided critiques
most useful in the preparation of this Working Paper series.
Major General LaClair A. Melhouse, the Adjutant General of
North Dakota, and Project Officer Colonel Irvin M. Sande, who
directed the volunteer efforts of the North Dakota National
Guardsmen, are also gratefully acknowledged for their assistance
to the Survey.

MATEJCEK LAKE
STORE! NO. 3808
I. CONCLUSIONS
A. Trophic Condition:
Survey data indicate that Matejcek Lake is eutrophic. It
ranked tenth in overall trophic quality when the 14 North Dakota
lakes sampled in 1974 were compared using a combination of six
lake parameters*. Eight of the lakes had less median total phos-
phorus, nine had less median dissolved orthophosphorus, 13 had
less median inorganic nitrogen, none had less mean chlorophyll
a_, and 12 had greater mean Secchi disc transparency. Marked
depression of dissolved oxygen with depth occurred at both sam-
pling stations in April and July.
Survey limnologists noted surface concentrations of algae
in July and September.
B. Rate-Limiting Nutrient:
The algal assay results indicate that the lake was nitrogen
limited in September. The lake data indicate nitrogen limita-
tion at all sampling stations and times.
C. Nutrient Controllability:
1. Point sources—No known point sources impacted Matejcek
Lake during the sampling year.
* See Appendix A.
-------
2
2. Non-point sources—Non-point sources contributed the
entire phosphorus loading to the lake during the sampling year.
The Middle Branch of the Forest River was the major source and
contributed about 78% of the loading. Minor tributaries and
immediate drainage contributed an estimated 21% of the loading.
The estimated phosphorus loading of 1.51 g/m2/year is three
times that proposed by Vollenweider (Vollenweider and Dillon,
1974) as a eutrophic loading (see page 11). A large reduction
in this loading would be necessary to result in significant
improvement in the trophic condition of the lake. However, since
much of the phosphorus load is the result of agricultural prac-
tices (Peterson, 1974), this may be difficult to achieve.

III. LAKE WATER QUALITY SUMMARY
Matejcek Lake was sampled three times during the open-water season
of 1974 by means of a pontoon-equipped Huey helicopter. Each time,
samples for physical and chemical parameters were collected from a
number of depths at two stations on the lake (see map, page v). During
each visit, a single depth-Integrated (4.6 m to surface) sample was
composited from the stations for phytoplankton identification and
enumeration; and during the last 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 £ analysis. The maximum depths sampled were 11.3
meters at station 1 and 7.6 meters at station 2.
The 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 Matejcek Lake was very high at the time the assay sample
was collected (09/16/74). Also, a significant increase in
yield with the addition of nitrogen alone indicates that the
lake was limited by nitrogen at that time. Note that the
addition of phosphorus alone did not result in a yield greater
than the control yield.
The lake data are also indicative of nitrogen limitation;
i.e., the mean inorganic nitrogen/orthophosphorus ratios were
7/1 or less on all sampling occasions.

IV. NUTRIENT LOADINGS
(See Appendix E for data)
For the determination of nutrient loadings, when possible the
North Dakota 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 month of May when two samples were
collected. Sampling was begun in September, 1974, and was completed
in August, 1975.
Through an interagency agreement, stream flow estimates for the
year of sampling and a "normalized" or average year were provided by
the North Dakota District Office of the U.S. Geological Survey for the
tributary sites nearest the lake.
In this report, nutrient loads for sampled tributaries were
calculated using mean annual concentrations and mean annual flows.
Nutrient loads for unsampled "minor tributaries and immediate drainage"
("ZZ" of U.S.G.S.) were estimated using the mean concentrations in the
Middle Branch Forest River at station A-2 and the mean annual ZZ flow.

F. 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.
Total Phosphorus Total Nitrogen
Total Accumulated Total Accumulated
grams/m2/yr 1.51 0.55 14.1 0.2
Vollenweider phosphorus loadings
(g/m2/yr) based on mean depth and mean
hydraulic retention time of Matejcek Lake:
"Dangerous" (eutrophic loading) 0.50
"Permissible" (oligotrophic loading) 0.25
