FOREWORD
The National Eutrophlcatlon Survey was Initiated 1n 1972 1n
response to an Administration commitment to Investigate the nation-
wide threat of accelerated eutrophlcatlon to freshwater lakes and
reservoirs.
OBJECTIVES
The Survey was designed to develop, 1n conjunction with state
environmental agencies, Information on nutrient sources, concen-
trations, 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 nonpolnt source pollution abatement 1n lake water-
sheds.
ANALYTIC APPROACH
The mathematical and statistical procedures selected for the
Survey's eutrophlcatlon 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 eutrophlcatlon 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 Us drainage
basin 1s documented. The report 1s formatted to provide state
environmental agencies with specific Information for basin
planning [§303(e)], water qualltv criteria/standards review
[§303(c)]t clean lakes [§314(a,bJ], 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 condition
are being made to advance the rationale and data base for refine-
ment 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 the U.S. Environmental Protection
Agency and to augment plans implementation by the states.
ACKNOWLEDGMENTS

REPORT ON UTE RESERVOIR, NEW MEXICO
STORE! NO. 3509
I. CONCLUSIONS
A. Trophic Condition:*
Survey data indicate that Ute Reservoir is mesotrophic.
Chlorophyll a_ values in the lake ranged from 1.0 yg/1 to
5.1 yg/1 with a mean of 3.2 yg/1. Secchi disc visibility
and the potential for primary productivity as measured by
algal assay control yield were low. Of the nine New Mexico
lakes (including Navajo Reservoir) sampled in 1975, seven
had higher median total phosphorus and median inorganic
nitrogen levels, and six had higher median orthophosphorus
levels than Ute Reservoir.
Survey limnologists did not report any problem algal
blooms or macrophyte growths during their visits to the lake.
The New Mexico Environmental Improvement Agency (1974) reports
that the water quality of the reservoir is generally good,
but the nutrient levels in the reservoir could lead to future
nuisance algal growths during low water years.
*See Appendix E.
-------
B. Rate-Limiting Nutrient:
Algal assay results indicate that Ute Reservoir was limited
by available phosphorus during the sample collection times (05/02/75,
10/03/75). Lake data suggest primary limitation by nitrogen in
the spring and summer and by phosphorus in the fall.
C. Nutrient Controllability:
1. Point sources -
There were no known point sources impacting Ute Reservoir
during the sampling year.
2
The estimated annual phosphorus loading of 0.66 g P/m/yr
is greater than that proposed by Vollenweider (1975) as a
"eutrophic" loading. Actual annual loading to the reservoir
may be somewhat higher than indicated; two of the tributaries
draining Ute Reservoir (Canadian River, Ute Creek) were dry at
most of the sample collection times and information on their
true nutrient contributions to the lake budget is not available
at present. Furthermore, heavy recreational use of the
reservoir may result in nutrient loading to the lake not
accounted for in this report (New Mexico Water Quality Control
Commission, 1975). In light of this possible underestimation
of nutrient contributions to Ute Reservoir, any proposed land
development adjacent to the lake should be carefully evaluated
as to its effect on the existing lake water quality.
-------
2. Nonpoint sources -
Nonpoint sources, including precipitation, were estimated
to have contributed all of the nutrient load to Ute Reservoir
during the sampling year. The New Mexico Environmental Improve-
ment Agency (1974) reports that nutrient enrichment in the lake
is primarily a result of natural leaching of nutrients from
the Upper Sonoran watershed, rather than from point sources.

II. LAKE AND DRAINAGE BASIN CHARACTERISTICS
Lake and drainage basin characteristics are itemized below.
Lake morphometry data were provided by Martin and Hanson (1966)
and Tony Drypolcher (personal communication). Tributary flow data
were provided by the New Mexico 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.

III. LAKE WATER QUALITY SUMMARY
Ute Reservoir was sampled three times during the open-water
season of 1975 by means of a pontoon-equipped Huey helicopter.
Each time, samples for physical and chemical parameters were col-
lected from four stations on the lake and from a number of depths
at each station (see map, page v). During each visit, depth-
integrated samples were collected from each station for chlorophyll
^analysis and phytoplankton identification and enumeration. During
the first and last visits, 18.9-liter depth-integrated samples were
composited for algal assays. Maximum depths sampled were 15.8 meters
at Station 01, 14.6 meters at Station 02, and 10.4 meters at Stations
03 and 04. For a more detailed explanation of NES methods, see
NES Working Paper No. 175.
The results obtained are presented in full in Appendix C 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 chloro-
phyll a_ determinations are included in III-B. Results of the limiting
nutrient study are presented in III-C.

2. Discussion -
The control yields of the assay alga, Selenastrum capricornutum,
indicate that the potential for primary productivity in Ute Reservoir
was low at both sample collection times (05/02/75, 10/03/75). In
the assays, the significant increase in yield over that of the control
when orthophosphorus was added as well as the lack of response to
the addition of nitrogen indicates phosphorus limitation. Maximum
yield was achieved with the simultaneous addition of nitrogen and
phosphorus.
The mean inorganic nitrogen to orthophosphorus (N/P) ratios
in the lake data of 4/1 and 10/1 in the spring and summer, respec-
tively, suggest primary limitation by nitrogen. The fall ratio of
15/1 suggests primary limitation by phosphorus (a mean N/P ratio
of 14/1 or greater generally reflects phosphorus limitation).

IV. NUTRIENT LOADINGS
(See Appendix D for data)
For the determination of nutrient loadings, the New Mexico
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 April and May when two samples were
collected. Sampling was begun in December 1974, and was completed
in November 1975.
Through an interagency agreement, stream flow estimates for
the year of sampling and a "normalized" or average year were pro-
vided by the New Mexico District Office of the USGS for the tribu-
tary sites nearest'the lake.
In this report, the nutrient load for the Canadian River at
Station A-l was determined by using a modification of a USGS com-
puter program for calculating stream loadings. Nutrient loads for
Romero Draw and Pajarito Creek at Stations C-l and D-l were cal-
culated from their respective mean annual concentrations and mean
annual flows. Nutrient loads indicated for tributaries are those
measured minus known point source loads, if any.
Nutrient loadings for unsampled "minor tributaries and immediate
drainage" ("22" of USGS) were estimated by using the mean annual
2
nutrient loads, in kg/km /year, in Romero Draw at Station C-l and
multiplying the means by the 22 area in km.

E. Yearly Loadings:
In the following table, the existing phosphorus annual
loading is compared to the relationship proposed by Vollenweider
(1975). Essentially, his "eutrophic" loading is that at which
the receiving waters would become eutrophic or remain eutrophic;
his "oligotrophic" loading is that which would result in the
receiving water remaining oligotrophic or becoming oligotrophic
if morphometry permitted. A "mesotrophic" loading would be
considered one between "eutrophic" and "oligotrophic".
Note that Vollenweider's model may not apply to lakes with
short hydraulic retention times or in which light penetration is
severely restricted by high concentrations of suspended solids
in the surface waters.

APPENDIX E
PARAMETRIC RANKINGS OF LAKES
SAMPLED BY NES IN 1975
STATE OF NEW MEXICO
Mean or median values for six of the key parameters evaluated
1n establishing the trophic conditions of New Mexico lakes sampled
are presented to allow direct comparison of the ranking, by parameter,
of each lake relative to the others. Median total phosphorus,
median Inorganic nitrogen and median dissolved orthophosphorus
levels are expressed in mg/1. Chlorophyll a_ values are expressed
in yg/1. To maintain consistent rank order with the preceding
parameters, the mean Secchi disc depth, in inches, 1s subtracted
from 500. Similarly, minimum dissolved oxygen values are subtracted
from 15 to create table entries.
