Assessment Comments
Assessment is based on biocriteria sampling in October 1995 (Biocriteria: Fish IBI = 41 (fair); BM-IBI = 48 (fair).
Basis for Assessment
SUMMARY: The Class B(LR) aquatic life uses remain assessed as "partially supported." The assessment category, however, is changed from "monitored" to "evaluated." EXPLANATION: Continue to use the assessment developed for the 1998 report (see above) that was based on results of the 1995 DNR biocriteria assessment. However, because these data are now considered too old to accurately characterize current water quality conditions, the assessment category is changed from "monitored" (indicating an assessment with relatively high confidence) to "evaluated" (indicating an assessment with relatively low confidence).
