Assessment Comments
Assessment is based on results of three DNR stream use assessments in August 1995.
Basis for Assessment
Used a review of the field sheets from the three August 1995 DNR stream use assessments in Mitchell County (NNE Stacyville, near L. Cedar, and at Pioneer Park) to continue to assess support of the Class B(WW) uses as FST due to (1) presence of very diverse fish communities (species/familes, dstr->upstr: 22/4; 23/5, 17/4) for streams in the Iowan Surface subecoregion (47c) with several environmentally sensitive species at each site, including rosyface shiner, northern hogsucker, smallmouth bass, fantail darter, banded darter, and logperch), (2) presence of a strong majority of the expected fish taxa (8/11; 9/11; 8/11) for streams in this subregion, (3) indications of good quality aquatic habitats at most sites, with diverse substrates and several pool/riffle sequences, and (4) presence of the expected game fish species (smallmouth bass) at all sites, with both juveniles and adults (from 12" to 15" TL) present. Field sheets indicate, however, that frequent pasturing the stream corridor, frequent streambank erosion, and excessive widening of the stream channel are threats to the continued support of the Class B(WW) uses.
