                          FOREWORD
    The National Eutrophication Survey was initiated in 1972 in
response to an Administration comrnitment 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.

-------
     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 Colorado Department of
Health for professional involvement, to the Colorado National
Guard for conducting the tributary sampling phase of the Survey,
and to those wastewater treatment plant operators who voluntarily
provided effluent samples.

     The staff of the Water Quality Control Division 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.

     Lt. Colonel Paul A. Parsons, the Deputy Adjutant General of
Colorado, and Project Officer Colonel Hershel C. Yeargan, who
directed the volunteer efforts of the Colorado National Guardsmen,
are also gratefully acknowledged  for their assistance to the Survey.

 I.   INTRODUCTION
     Accurate flow data could not be provided  for Milton Reservoir
 by  the U.S.  Geological  Survey because water enters and leaves  the lake
 through ungaged inlet and outlet canals.   Therefore,  this  report pri-
 marily pertains to the lake sampling data.  However,  tributary and
 wastewater treatment plant samples were  collected, and the results
 of  the analyses are presented in Appendix D.
II.   CONCLUSIONS
     A.   Trophic Condition:
             Survey data indicate Milton  Reservoir is  eutrophic.   It
         ranked tenth in overall  trophic  quality when  the 13 Colorado
         lakes and reservoirs sampled in  1975  were compared using a com-
         bination of six parameters*.   Eleven  of the water  bodies had  less
         median total  phosphorus, 12 had  less  median dissolved  orthophosphorus
         and inorganic nitrogen,  six had  less  mean chlorophyll  £, and  six
         had greater mean Seechi  disc transparency.
     B.   Rate-Limiting Nutrient:
             The algal  assay results indicate  the primary productivity  of
         Milton Reservoir was nitrogen limited at the  time  the  sample was
         collected (05/06/75).   The reservoir  data indicate nitrogen limi-
         tation at all  sampling times.

IV.   WATER QUALITY SUMMARY
     Milton 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  collected
 from one or more depths at two stations  on  the reservoir (see map,
 page v).   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 May
 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 6.4 meters  at station 1  and  3.4  meters
 at  station 2.
     The sampling results  are  presented  in full  in Appendix C and
 are summarized in the following table.

    2.   Discussion -
            The control yield  of the  assay alga, Selena strum c_aprj_-
        cornutum. indicates that the  potential  primary productivity
        of Milton Reservoir was high  at the time the assay sample
        was collected (05/06/75).  Also,  the addition of nitrogen
        alone and in combination with  phosphorus resulted in a sig-
        nificant increase in yield which  indicates the reservoir was
        nitrogen limited at that time.   Note that  the addition of
        phosphorus alone resulted in  a  yield not significantly greater
        than that of the control.
            The reservoir data substantiate nitrogen limitation.  The
        mean inorganic nitrogen to orthophosphorus ratios were 4 to 1
        or less  at all sampling times.
