Assessment Comments
1995 biocriteria: habscr/fshscr = 31/13 (shock, 18 spp., 5 fams.).
Basis for Assessment
Used a review of results from the July 1995 DNR biocriteria sampling in Dubuque County to upgrade the assessment of support of the Class B(CW) uses from FST to FS due to (1) presence of the expected game fish species (i.e., brown trout (6), rainbow trout (2), & brook trout (3)), (2) presence of a very diverse fish community (18 species from 5 families) for streams in the Driftless Area ecoregion (52), (3) presence of all the expected fish taxa (9 of 9) for streams in this region, and (4) indications of very high quality aquatic habitats.
