                         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 fresh water 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)L 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.

-------
                                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.

I.   CONCLUSIONS
    A.  Trophic Condition:
            Survey data indicate that Woods Pond is a hypereutrophic
        impoundment which receives heavy loads of phosphorus  from muni-
        cipal  and industrial  sources.  Heavy algal  blooms  and broad
        surface coverage by duckweed are recurrent phenomena.  High algal
        assay  control  yields  substantiate the high primary productivity
        reported.  Turbidity  was high and dissolved oxygen was depressed
        when sampled.
    B.  Rate-Limiting  Nutrient:
            Algal assay results  indicate that Woods Pond was  nitrogen
        limited at the time the  sample was collected.   The ratio of inor-
        ganic  nitrogen to dissolved phosphorus (approximately 3 to 1 on
        each sampling  date) indicates that nitrogen limitation is a
        sustained rather than a  transient condition in the pond.
    C.  Nutrient Controllability:
            1.   Point  sources—During the sampling year, Woods Pond
        received a total  phosphorus load at a rate more than  60 times
        that proposed  by Vollenweider (in press) as "dangerous"; i.e.,
        a eutrophic rate (see page 12).  Now, Vollenweider's  model
        probably does  not apply  to water bodies with short detention

-------
times, and the mean hydraulic retention time of Woods Pond is
a very short 19 hours.  Nonetheless, the existing trophic condi-
tion of the pond is evidence of excessive nutrient loads.
    It is estimated that the point sources considered in this
study collectively contributed over 93% of the total  phosphorus
load.  While even complete removal of phosphorus at these sources
would still leave a loading rate nearly four times the eutrophic
rate, considering the very short hydraulic retention time of Woods
Pond and the probability that Vollenweider's model is not applicable,
it is likely that a high degree of phosphorus removal at the point
sources would result in a decrease in the incidence and severity
of nuisance algal blooms as well as reduce the phosphorus loading
to downstream Housatonic River impoundments.
    2.  Non-point sources—The estimated non-point phosphorus
                                                 2
export rate of the Housatonic River of 107 Ibs/mi /yr is comparable
to the export rates of Massachusetts streams studied elsewhere; e.g.,
Hager Pond and Rochdale Pond tributaries.
    In all, it is estimated that non-point sources, including pre-
cipitation, contributed a little over 7% of the total phosphorus
load to Woods Pond during the sampling year.

III.  LAKE WATER QUALITY SUMMARY
      Woods Pond was sampled three times during the open-water season  of
  1972 by means of a pontoon-equipped Huey helicopter.   Each  time,  samples
  for physical  and chemical  parameters were collected from a  number of depths
  at the single station on the pond (see map, page v).   During each visit,  a
  depth-integrated (near bottom to surface) sample was  collected  for phyto-
  plankton identification and enumeration, and a similar sample was collected
  for chlorophyll  ^analysis.  During the last visit, a single five-gallon
  depth-integrated sample was collected for algal  assays.   The maximum depth
  sampled was four feet.
      The results  obtained are presented in full in Appendix  B, and the data
  for the fall  sampling period, when the pond essentially  was well-mixed,
  are summarized below.  Note, however, the Secchi disc summary is  based on
  all values.
      For differences in the various parameters at the  other  sampling  times,

    2.  Discussion -
            The  control yield of the assay alga, Selenastrum capri-
        cornutum, indicates that the primary productivity in Woods
        Pond was very high at the time  the assay sample was col-
        lected.   The lack of significant increases in yield with
        increasing levels of phosphorus spikes, until  nitrogen was
        also added, indicates that nitrogen was the limiting nutrient.
        Note that there was a significant increase in yield (compared
        to the control  yield) when only nitrogen was added.
            The  pond data indicate nitrogen limitation  at the other
        sampling times  as well (N/P ratios were less than 3/1, and
        nitrogen limitation would be expected).

-------
IV.   NUTRIENT LOADINGS
     (See Appendix C for data)
     For the determination of nutrient loadings,  the  Massachusetts  National
 Guard collected monthly near-surface grab samples  from each  of  the tribu-
 tary sites indicated on the map (page v), except for the  high runoff months
 of  March and April  when two samples were collected.   Sampling was  begun  in
 September, 1972, and was completed in October,  1973.
     Through an interagency agreement, stream flow  estimates  for the year
 of  sampling and a "normalized" or averaged year  were provided by the
 New England District Office of the U.S.  Geological Survey for the  tribu-
 tary sites nearest  the lake.
     In this report, the nutrient loads of the outlet at station A-3 were
 calculated using the mean concentrations and the mean annual flow. However,
 the phosphorus loads calculated in this  way for  the  Housatonic  River inlet
 at  station A-2 were less than the sum of the upstream point-source loads,
 so  the background phosphorus load of the river was estimated using the mean
 annual flow at station A-2 and the mean  of the  phosphorus concentrations
 measured in 1974 in the East and West1 branches  of  the Housatonic River
 (0.030 mg/1) by the Massachusetts Division of Water  Pollution Control
 (Anonymous, 1974).
     The nitrogen load for unsampled "minor tributaries and immediate drain-
 age" ("ZZ" of U.S.G.S.) was estimated by using  the adjusted  (minus point

-------
                                                        2
source) Housatonic River load, at station A-2, in Ibs/mi  /year, and
                                2
multiplying by the ZZ area in mi .  The ZZ phosphorus load was calcu-
lated using the mean phosphorus concentrations as at station A-2 and
the mean annual ZZ flow.
    The operator of the Pittsfield wastewater treatment plant provided
monthly effluent samples and corresponding flow data.  However, the
North Lennox wastewater treatment plant and the General Electric Company
discharges were not sampled, and the nutrient loads attributed to these
sources were provided by the Massachusetts Division of Water Pollution
Control (Chesebrough, 1975; Cooperman, et al., 1971).
    It is assumed that the entire point-source nutrient loads reached
Woods Pond during the sampling year.

    E.  Yearly  Loading  Rates:
             In  the following table, the existing phosphorus loading
        rates are compared to those proposed by Vollenweider (in press).
        Essentially, his  "dangerous" rate is the rate at which the
        receiving waters would become eutrophic or remain eutrophic;
        his  "permissible" rate is that which would result in the
        receiving water remaining oligotrophic or becoming oligotrophic
        if morphometry permitted.  A mesotrophic rate would be consid-
        ered one between  "dangerous" and "permissible".
            Note that Vollenweider's model may not be applicable to
        water bodies with very short hydraulic retention times.

            "Permissible"  (oligotrophic rate)  2.20
* There was an apparent loss of nitrogen during the sampling year.  This may
  have been due to nitrogen fixation in the pond, solubilization of previously
  sedimented nitrogen, recharge with nitrogen-rich ground water, unknown and
  unsampled point sources discharging directly to the pond, or underestimation
  of the nitrogen loads from Pittsfield, North Lennox, and/or the General
  Electric Co. discharges.  Whatever the cause, a similar nitrogen loss has
  occurred at Shagawa Lake, Minnesota, which has been intensively studied by
  EPA's National Eutrophication and Lake Restoration Branch.
