Assessment Comments
Assessment is based on results of a DNR stream use assessment in November 1994.
Basis for Assessment
Used results of the November 1994 DNR stream use assessment to assess support of the Class B(LR) aquatic life uses as PS due to (1) habitat score (21) less than the overall median score (22) for DNR stream use assessments, (2) fish score (7) worse than the 75th percentile score (10) for stream assessments made with seines (although the field sheet notes that large boulders and muck hindered effective seining), and (3) indications on field sheet of little substrate diversity, few pool/riffle sequences, and frequent channel alterations due to over pasturing.
