Assessment Comments

Stream use assessment in 1992.

Basis for Assessment

Used a review of the field sheet from the October 1992 DNR stream use assessment S of Boone to upgrade the assessment of support of the Class B(LR) aquatic life uses from FST to FS due to (1) presence of relatively diverse fish community (12 species from 5 families) for streams in the Des Moines Lobe subecoregion (47b), (2) presence of nearly all of the expected fish taxa (9 of 11) for streams in this subregion, and (3) presence of above average habitat quality with a riparian corridor that meanders through a relatively undisturbed wooded valley.   The field sheet does not indicate any significant threats to the continued support of the Class B(LR) uses.
