mouth (S31 T93N R8W Fayette Co.) to confluence with unnamed tributary in S12 T93N R9W Fayette Co.
Assessment Comments
Stream use assessment in Fayette County.
Basis for Assessment
Used a reiew of the field sheet from the October 1991 DNR stream use assessment in Fayette County to assess support of the Class B(LR) aquatic life uses as FST due to (1) presence of a moderately diverse fish community (9 species from 3 families) for streams in the Iowan Surface subecoregion, (2) presence of a majority of the expected fish taxa (8 of 11) for streams in this subregion, and (3) indications of approximately average habitat, with diverse substrates and a few pool/riffle sequences. Frequent pasturing of the riparian zone was identified as an impact to the physical characteristics of this stream reach. The data upon which this assessment is based are more than 5 years old. Additional monitoring is needed to update this assessment and to determine the status of the aquatic communities and habitats.
