Assessment Comments

Stream use assessment in October 1991.

Basis for Assessment

Used a review of the field sheet from the October 1991 DNR stream use assessment NE of Atlantic to upgrade the assessment of support of the Class B(LR) aquatic life uses from FST to FS due to (1) presence of a very diverse fish community (14 species from 4 families) for streams in the Loess Hills and Rolling Prairies (47e) subecoregion, (2) presence of all the expected fish taxa (7 of 7) for streams in this subecoregion, and (3) indications on field sheet of above average habitat quality.   Field sheet notes frequent streambank erosion, but the condition of the fish community does not suggest a threat to the Class B(LR) uses.   The data upon which this assessment is based are more than 5 years old.  Additional monitoring is needed update this assessment and to determine the status of the aquatic communities and habitats.
