SUMMARY OF VOLUNTEER SURVEY There was no survey response for 1995. FIELD OBSERVATIONS OF ECOLOGY STAFF No field visits were made to Haller Lake.
TROPHIC STATUS Estimated Trophic State: Mesotrophic Mean Trophic State Index (Secchi): 42N* (Mesotrophic) Mean Trophic State Index (Total Phosphorus): 0 (Not assessed) Mean Trophic State Index (Chlorophyll a): 0 (Not assessed) *The calculated TSI is an estimate. The Secchi disk hit bottom (B), entered the weeds (W), or there were too few valid readings (N), or the calculation was based on qualified data (J), or TSIP was based on spring data (S).
SUMMARY AND EXPLANATION OF TROPHIC STATE ASSESSMENT Since only Secchi data is provided, the assessment is based on Secchi TSI along with notes from the volunteer. This lake is classified as mesotrophic.
