Assessment Comments

1991 stream use assessment in Jackson County.

Basis for Assessment

Used a review of the field sheet from the October 1991 DNR stream use asssessment in Jackson County to upgrade the assessment of support of the Class B(LR) aquatic life uses from FST to FS due to (1) a moderately diverse fish community (10 species from 3 families) for streams in the Driftless Area ecoregion (52) despite difficulty with sampling (seining) amongst rocks and snags, (2) presence of nearly all the expected fish taxa (7 of 9) for streams in this ecoregion, and (3) indications of above average habitat quality with very diverse substrates, numerous pool/riffle sequences, with no significant impacts to the physical characteristics of this stream reach.  The data upon which this assessment is based are more than 5 years old.  Additional monitoring is needed to update this assessment.
