Assessment Comments
Stream use assessment in 1992.
Basis for Assessment
Used results of the October 1992 DNR stream use assessment to assess support of the Class B(LR) aquatic life uses as PS due to (1) habitat score (19) worse than the overall median habitat score (22) for DNR stream use assessments and (2) indications on field sheet of no pool/riffle development, extensive channel straightening, and unstable stream banks. Fish community with moderate diversity and fish score (10) equal to the 75th percentile for stream use assessments made with seines.
