Assessment Comments
Stream use assessment in Fayette County.
Basis for Assessment
Used a review of the field sheet from the October 1991 DNR stream use assessment in Clayton County to continue to assess support of the Class B(LR) aquatic life uses as FST due to (1) presence of a majority of the expected fish taxa (5 of 9) for streams in the Driftless Area ecoregion, (2) indications on field sheet of above average quality of aquatic habitats due to diverse substrates, presence of several pool/riffle sequences, lack of significant impacts to the physical characteristics of this stream, and good low-flow characteristics. Results of biological sampling (seining) were hindered by presence of snags. The data upon which this assessment is based are more than 5 years old. Additional monitoring is needed to update this assessment and to better define the status of the aquatic communities and habitats.
