Stream use assessment.

Basis for Assessment

Used a review of the field sheet from the September 1992 DNR stream use assessment to continue to assess support of the Class B(LR) aquatic life uses as FST due to (1) a moderately diverse fish community (10 species from 2 families) for streams in the Des Moines Lobe subecoregion (47b) and (2) presence of a majority of the expected fish taxa (7 of 11) for streams in this region.   Field sheet indicates above average habitat quality with no significant threats to continued support of the Class B(LR) uses.
