Bear Creek IA 02-IOW-702
from confluence with L. Bear Cr. (S16 T80N R13W Poweshiek Co.) to confluence with unnamed tributary in SW 1/4 S9 T80N R14W Poweshiek Co.
Assessment Comments
Assessment is based on results of a DNR stream use assessment in August 1994.
Basis for Assessment
Used a review of the field sheet from the August 1994 DNR stream use assessment in Poweshiek County to continue to assess support of the Class B(LR) aquatic life uses as FST due to (1) presence of a moderately diverse fish community (12 species from 4 families) for streams in the Southern Iowa Rolling Loess Prairies subecoregion (47f), (2) presence of a majority of the expected fish taxa (6 of 8) for streams in this subregion), and (3) indications on field sheet of above average habitat quality, especially due to diverse substrates and presence of several pool/riffle sequences. As indicated on field sheet, the most significant impacts to the physical characteristics of this stream are frequent channel alterations (unspecified) and frequent stream bank erosion.
