Assessment Comments

Assessment is based on results of a September 1994 DNR stream use assessment.

Basis for Assessment

Used results of the September 1994 stream use assessment to assess support of the Class B(LR) aquatic life uses as PS due to (1) habitat score (21) poorer than the overall habitat score (22) for DNR stream use assessments, (2) indication on field sheet of extensive channel alterations (stream channelization), (3) comments on field sheet regarding "many areas too shallow for aquatic habitat."
