Assessment Comments

Stream use assessment in November 1990.

Basis for Assessment

Used a review of the field sheet from the November 1990 DNR stream use assessment to upgrade the assessment of support of the Class B(LR) aquatic life uses from FST to FS due to (1) presence of a relatively diverse fish community (14 species from 5 families) for streams of the Central Irregular Plains (40) ecoregion, (2) presence of all the expected fish taxa (8 of 8) for streams in this region, and (3) no indications on field sheet of threats to the continued support of the Class B(LR) uses.   The data upon which this assessment is based, however, are more than five years old; thus, additional monitoring is needed to update this assessment and to determine the status of the aquatic communities and habitats of this stream.
