Stream use assessment in Buchanan County.

Basis for Assessment

Used a rewview of the field sheet from the October 1991 DNR streamuse assessment in Buchanan County to continue to assess support of the Class B(LR) aquatic life uses as FST due to (1) presence of a relatively diverse fish community (12 species from 4 families) for streams in the Iowan Surface subecoregion (47c), (2) presence of a majority of the expected fish taxa (8 of 11) for streams in this subregion, and (3) indications on field sheet of above average quality of aquatic habitats due to presence of diverse substrates, several pool/riffle sequences, and lack of significant threats to the physical characteristics of this stream.  The data upon which this assessment is based are more than 5 years old.  Additional monitoring is needed to update this assessment.
