Assessment Comments

Three stream use assessments in 1990 and one SUA in 1994.

Basis for Assessment

Used the four DNR stream use assessments conducted in November 1990 (3) and September 1994 (1) to assess support of the Class B(LR) aquatic life uses as FST due to (1) habitat scores (22, 21, 26 & 20) generally equal to or better than the overall median score (22) for DNR stream use assessments, (2) indicaitons on field sheets of diverse substrates, occurrence of pool/riffle sequences, and reaches with only isolated channel alterations (straightening), (3) comments on field sheets regarding "relatively good habitat," "good depth and tree snag areas; nice habitat for many species," "very nice riffle area approx.  500' long," and (4) moderately diverse fish community:  13 species from 5 families.  Field sheet suggests that continued support of the aquatic life uses is threatened by channel alterations (channel straightening).
