                               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.

-------
                                    111
     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.

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.

                          Phosphorus Loading
                               (g/m2/yr)
     Estimated loading for Ute Reservoir                         0.67
     Vollenweider's "eutrophic" loading                          0.48
     Vollenweider's "oligotrophic" loading                       0,24

                   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.
