Assessment Comments

Stream use assessment in 1992.

Basis for Assessment

Used results of the June 1992 DNR stream use assessment to assess support of the Class B(LR) aquatic life uses as FST due to (1) habitat score (27) much better than the overall median score (22) for DNR stream use assessment, (2) indications on field sheet of very diverse substrates, numerous pool/riffle sequences, only isolated channel alterations, and very stable stream banks, (3) comments on field sheet noting high quality aquatic habitat, and (4) fish score (11) better than the 75th percentile score (10) for stream assessments made with seines (seining effeciency lowered by uneven stream bottom and woody debris).
