Assessment Comments

1992 stream use assessment in Winneshiek County.

Basis for Assessment

Used a review of the field sheet from the June 1992 DNR stream use assessment to continue to assess support of the Class B(LR) aquatic life uses as FST due to (1) presence of a moderately diverse fish community (9 species from 2 families) for Class B(LR) streams in the Driftless Area ecoregion, (2) presence of a majority of the expected fish taxa (7 of 9) for streams in this region, (3) indications of high quality aquatic habitats and riparian corridor due to presence of diverse substrates, several pool/riffle sequences, no channel alterations, and only isolated areas of streambank erosion, and (4) notes on field sheet ("minnows very abundant").   Seining likely hindered by rocky substrate; sampling with more effective gear type (e.g., BP electrofisher) would likely increase the number of taxa collected.
