     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 Lake Che'lan is oligotrophic.  It
        ranked first in overall trophic quality among the 13 Washington
        lakes and reservoirs sampled in 1975 when compared using a com-
        bination of six water quality parameters**.   None of the other
        water bodies had less median total phosphorus or mean chlorophyll
        a_, one had less median orthophosphorus, four had less median
        inorganic nitrogen, but none of the others had greater mean
        Secchi disc transparency.  No significant depression of dis-
        solved oxygen with depth occurred at any of the sampling stations
        or times.
    B.  Rate-Limiting Nutrient:
            The algal assay results indicate the lake was phosphorus
        limited at the time the sample was collected (09/11/75).  The
        lake data indicate phosphorus limitation in April and September
        but nitrogen limitation in July.
    C.  Nutrient Controllability:
            1.  Point sources—The septic-tank phosphorus contributions
        of the community of Manson and those serving lakeshore dwellings
        amounted to an estimated 1.7% of the total phosphorus input to
* Trophic assessment is based on the levels of nutrients, dissolved
  oxygen, and chlorophyll a_; phytoplankton kinds and numbers; and trans-
  parency (Allurn et al.,  1977).

Lake Chelan during the sampling year.   However, additional  study
would be necessary to determine the significance of those sources.
    The estimated phosphorus loading of 0.26 g/m2/year is a little
more than that proposed by Vollenweider (Vollenweider and Dillon,
1974) as an oligotrophic loading (see page 12).
    2.  Non-point sources--Non-point sources accounted for 98.3%
of the total phosphorus load during the sampling year.  The Stehekin
River contributed 51.5%, Railroad Creek contributed 5.8%, and the
ungaged minor tributaries and immediate drainage contributed an
estimated 34.2%.

III.   WATER QUALITY SUMMARY
      Lake Chelan 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 a number of  depths
  at six stations on the lake in July and  from seven stations in April  and
  September (see map, page v).   During each visit,  a single depth-integrated
  (4.6 m to surface) sample was composited from the stations for phytoplankton
  identification and enumeration; and during the last visit,,two 18.9-liter
  depth-integrated samples were 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 11.6 meters  at
  station 1 and 67.1 meters at each of the other six stations.
      The sampling results are presented in full in Appendix C and  are  sum-
  marized in the following table.

    2.   Discussion -

            The control  yields  of the  assay  alga,  Selenastrum capri-

        cornutum,  indicate that the  potential  primary  productivity of

        Lake Chelan was  moderate at  the  time samples were collected

        (09/11/75).  Also, the  significant increases in yields with the

        addition of orthophosphorus  alone indicate phosphorus limita-

        tion at that time.  Note that  the addition of  nitrogen alone

        resulted in yields not  significantly different from those of

        the controls.

            The lake data  indicate phosphorus  limitation in April and

        September; i.e.,  the mean inorganic  nitrogen/orthophosphorus

        ratios  were 17/1  or greater.   However,  nitrogen limitation is

        indicated  in July; i.e., the mean N/P  ratio was 8/1, and nitrogen

        limitation would be expected (N/P ratios of 14/1 or greater

        generally  indicate phosphorus  limitation).

-------
IV.   NUTRIENT LOADINGS
     (See Appendix D for data)
     For the determination of nutrient loadings, the Washington National
 Guard collected monthly near-surface grab samples from each of the tribu-
 tary sites indicated on the map (page v).   Sampling was begun in September,
 1974, and was completed in October, 1975.
     Stream flows are those reported by the U.S. Geological  Survey (Anonymous,
 1976) and are the average discharges for 54 years of record on the Stehekin
 River (U.S.G.S. station 12451000) and 71 years record on the Chelan River
 (U.S.G.S. station 124525000).   Water diverted through the aqueduct is
 unmeasured, and flow is estimated by U.S.G.S. (station 12452000).  The flow
 for Railroad Creek is that given in a previous report on Lake Chelan
 (Cunningham and Pine, 1968).
     In this report, nutrient loads for sampled tributaries were calculated
 from mean annual concentrations and mean annual flows.  Nutrient loads for
 unsampled "minor tributaries and inrnediate drainage" ("ZZ" of U.S.G.S.)  were
 estimated using the mean concentrations in Stink Creek, Poison Creek, Twenty
 Five Mile Creek, Grade Creek,  Prince Creek, and Moon Creek at stations C-l,
 D-l, E-l, F-l, G-l, and K-l and the mean annual ZZ flow.
     The operator of Manson waste treatment plant did not participate, and
 nutrient loads were estimated  at 1.134 kg P and 3.401 kg N/capita/year.

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  mesotrophic 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.

    Vollenweider phosphorus loading
     (g/m2/yr) based on mean outflow
     and area of Lake Che!an:
        "Dangerous"  (eutrophic loading)                  0.40
        "Permissible"  (oligotrophic loading)             0.20
