Upper Iowa River IA 01-UIA-245
from confluence with unnamed tributary (NE 1/4 S21 T100N R12W Howard Co.) to IA/MN state line in S11 T100N R14W Howard Co.
Assessment Comments
Previous assessment was based on results of DNR stream use assessment in September 1995.
Basis for Assessment
Used a review of the field sheet from the September 1995 DNR stream use assessment near Chester to continue to assess support of the Class B(WW) uses as FST due to (1) presence of a very diverse fish community for Class B(WW) streams in the Iowan Surface subecoregion (47c), (2) presence of nearly all the expected fish taxa (9 of 11) for streams in this subregion, (3) presence of the expected game fish species (smallmouth bass), with both adults and juveniles present and (4) indications of above average habitat quality due to presence of diverse substrates and to lack of significant impacts to the physical characteristics of this stream reach.
