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
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.
ACKNOWLEDGEMENT
The staff of the National Eutrophication Survey (Office of
Research & Development, U. S. Environmental Protection Agency)
expresses sincere appreciation to the Texas Water Quality Board
for professional involvement, to the Texas National Guard for
conducting the tributary sampling phase of the Survey, and to
those Texas wastewater treatment plant operators who voluntarily
provided effluent samples.
Hugh C. Yantis, Jr., Executive Director of the Texas Water
Quality Board, and John B. Latchford, Jr., Director, and the staff
of the Field Operations Division provided invaluable lake documen-
tation and counsel during the Survey, reviewed the preliminary
reports, and provided critiques most useful in the preparation of
this Working Paper series.
Major General Thomas Bishop, the Adjutant General of Texas,
and Project Officer Colonel William L. Seals, who directed the
volunteer efforts of the Texas National Guardsmen, are also grate-
fully acknowledged for their assistance to the Survey.

LAKE LAVON
STORE! NO. 4819
I. CONCLUSIONS
A. Trophic Condition:
Survey data indicate that Lake Lavon is eutrophic; i.e, well
supplied with nutrients and quite productive. Whether nutrient
enrichment is beneficial or deleterious depends on the actual
or potential effect on the uses of the lake. In this regard, the
Texas Water Quality Board has indicated that there is little or
no known impairment of the designated beneficial uses of this lake.
Lake Lavon ranked twenty-seventh in overall trophic quality when
the 39 Texas reservoirs sampled in 1974 were compared using a combi-
nation of six parameters*. Thirty of the reservoirs had less
median total phosphorus, 29 had less and two had the same median
dissolved orthophosphorus, 26 had less and one had the same median
inorganic nitrogen, six had less mean chlorophyll d_, and 37 had
greater mean Secchi disc transparency. No significant depression
of dissolved oxygen with depth (to 6.7 meters) occurred at any of
the four sampling times.
Survey limnologists noted the lake was very turbid. The tur-
bidity of Lake Lavon is noted in another report (Moczygemba, 1974).
B. Rate-Limiting Nutrient:
Due to significant changes in nutrient levels in the sample,
the algal assay results are not representative of conditions in
the lake at the time the sample was taken.
* See Appendix A.
-------
The lake data indicate that most sampling stations were nitro-
gen limited in March, August, and October, but all were phosphorus
limited in May. However, because of turbidity, primary produc-
tivity probably is frequently light-limited rather than nutrient-
limited.
C. Nutrient Controllability:
1. Point sources—It is calculated that known point sources
contributed about 31% of the total phosphorus load to Lake Lavon
during the sampling year. The McKinney South plant contributed
nearly 19% of the total phosphorus load.
During the sampling year, the lake received a total phosphorus
loading almost 2.5 times that proposed by Vollenweider (Vollen-
weider and Dillon, 1974) as a eutrophic loading (see page 15). It
seems unlikely that even 85% removal of phosphorus at all the treat-
ment plants would result in significant improvement in the trophic
condition of the lake, especially in view of the probability that
primary productivity frequently is light-limited.
2. Non-point sources—It is estimated that non-point sources
contributed about 69% of the total phosphorus load to Lake Lavon
during the sampling year. The East Fork of the Trinity River con-
tributed 32.8% of the total phosphorus load, and Wilson and Pilot
Grove Creeks contributed 12.2% each.
Note that the phosphorus export rates of the East Fork and
Wilson Creek were somewhat high at 54 and 37 kg/km2/yr, respectively
(see page 14); these high rates may be due to urban runoff and/or
unknown point sources in the vicinity of the City of McKinney.

III. LAKE WATER QUALITY SUMMARY
Lake Lavon was sampled four times in 1974 by means of a pontoon-
equipped Huey helicopter. Each time, samples for physical and chemical
parameters were collected from two or more depths at four stations on
the lake (see map, page vi). 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 6.7 meters at station 1, 3.0 meters at station 2, 4.9 meters
at station 3, and 1.8 meters at station 4.
The sampling results are presented in full in Appendix D and are
summarized in the following table.

C. Limiting Nutrient Study:
Significant nutrient changes occurred in the assay sample
during shipment to the laboratory, and the results are not
indicative of conditions in the lake at the time the sample
was taken (03/08/74).
The lake data indicate a temporal and spacial combination
of limiting nutrients. Following is a tabulation of the mean
inorganic nitrogen/orthophosphorus ratios at each of the sampling
stations and times with the indicated limiting nutrient in paren-
theses:

As indicated on page 1, Lake Lavon is turbid, and primary pro-
ductivity probably is light-limited at times rather than nutrient-
limited. Note that Secchi disc transparencies ranged from 0.2 to
0.6 meters, and only 1% of the incident light remained at depths
ranging from 0.6 to 1.5 meters (Appendix D).

IV. NUTRIENT LOADINGS
(See Appendix E for data)
For the determination of nutrient loadings, the Texas National
Guard collected monthly near-surface grab samples from each of the
tributary sites indicated on the map (page vi), except for the months
of April and May when two samples were collected at most of the sites.
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 Texas District Office of the U.S. Geological Survey for the
tributary sites nearest the lake.
In this report, nutrient loads for gaged and sampled tributaries,
except for Indian Creek, were determined 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 at stations C-l, F-l, and G-l, in kg/km2/year, and
multiplying the means by the ZZ area in km2. This method was also
used to estimate the non-point loads for Indian Creek which received
an estimated point-source phosphorus load greater than the load
measured at station J-l.
See Working Paper No. 175.

The operators of the Farmersville, McKinney, Princeton, Seis Lagos,
and Van Alstyne wastewater treatment plants provided monthly effluent
samples and corresponding flow data. Posey Mobile Home Acres and the
communities of Anna, Blue Ridge, Leonard, Tom Bean, and Trenton did
not participate; nutrient loads from these sources were estimated at
1.134 kg P and 3.401 kg N/capita/year, and flows were estimated at
0.3785 m3/capita/day.

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

grams/m2/yr 1.03 0.79 10.1 5.5
Vollenweider phosphorus loadings
(g/m2/yr) based on mean depth and mean
hydraulic retention time of Lake Lavon:
"Dangerous" (eutrophic loading) 0.42
"Permissible" (oligotrophic loading) 0.21
