Assessment Comments
Assessment is based on results of a 1997 biocriteria sampling : Fish IBI= 81(excellent), BM-IBI= 80(excellent).
Basis for Assessment
Used results of the September 1997 DNR biocriteria sampling NE of Decorah to update the assessment of support of the Class B(WW) aquatic life uses. Used these results to upgrade the assessment of support of the Class B(WW) uses from FST to FS due to (1) presence of a very diverse fish community (27 species from 7 families) including sensitive species (e.g., gravel chub, rosyface shiner, black redhorse, brown trout, smallmouth bass, and rainbow darter), (2) presence of nearly all the expected fish taxa (8 of 9) for streams in the Driftless Area ecoregion, (3) presence of the the expected game fish species (i.e., smallmouth bass; also brown trout), and (4) lack of violations of Class B(WW) WQ criteria in the sample collected during biocriteria sampling.
