Winnebago River IA 02-WIN-831
from confluence with Pike Run (S25 T99N R24W Winnebago Co.) to the Iowa/Minnesota state line
Assessment Comments
Assessment is based on results of 1995 stream use assessment and 1995 biocriteria assessment.
Basis for Assessment
Used a review of the September 1995 DNR stream use assessment, and results of the August 1995 DNR biocriteria sampling (both in Winnebago County) to continue to assess support of the Class B(LR) aquatic life use as FST due to (1) presence of a relatively diverse fish community (17 species from 7 families (biocriteria sampling)), (2) presence of a majority of the expected fish taxa for low gradient streams of north central Iowa, and (3) indications of above average habitat quality at both assessment sites, with a well-meandered channel form. Frequent streambank erosion was noted as a impact to the physcial characteristics of the stream at the DNR stream use assessment site.
