Assessment Comments

DNR stream use assessment in October 1994.

Basis for Assessment

Used a review of the field sheet from the October 1994 DNR stream use assessment in Fayette County to upgrade the assessment of support of the Class B(LR) aquatic life uses from FST to FS due to (1) presence of a moderately diverse fish community (11 species from 3 families) for streams in the Driftless Area ecoregion (52), despite notes on field sheet indicating difficulty sampling fish from rock substrates, (2) presence of nearly all the expected fish taxa (8 of 9) for Class B(LR) streams in this region, and (3) indications of very high quality aquatic habitats and riparian corridor due to very diverse substrates, numerous pool/riffle sequences, and no impacts to the physical characteristics of this stream.
