Assessment Comments
Assessment based on biocriteria data and stream use assessment.
Basis for Assessment
Used a review of the field sheet from the July 1992 DNR stream use asessment and the August 1995 DNR biocriteria sampling in Mitchell County to upgrade the assessment of support of the Class B(LR) uses to FS due to (1) presence of a moderately diverse to very diverse fish community (species/families, SUA->biocriteria: 10/3; 27/5) for streams in the Iowan Surface subecoregion, (2) presence of a majority (7 of 11, SUA) to nearly all (10 of 11, biocriteria) of the expected fish taxa for streams in this subregion, (3) indications on the SUA field sheet of average to above average habitat quality, and (4) presence of several environmentally sensitive species (e.g., largescale stoneroller, Ozark minnow, rosyface shiner, northern hogsucker, smallmouth bass, and rainbow darter).
