Turkey River IA 01-TRK-154
from confluence with Bohemian Cr. (S11 T97N R10W Winneshiek Co.) to Vernon Springs (road crossing in S34 T99N R11W Howard Co.)
Assessment Comments
DNR stream use assessment conducted in September 1995.
Basis for Assessment
Used results of the September 1995 DNR stream use assessment at Vernon Springs to assess support of the Class B(WW) aquatic life uses as FST due to (1) habitat score (27) better than the overall median score (22) for DNR stream use assessments, (2) indications on field sheet of above average habitat characteristics and low-flow characteristics, and (3) presence of an extremely diverse fish community (24 species; 4 families) despite difficult sampling conditions (high, turbid water). Field sheet does not suggest any threats to continued support of the aquatic life uses. Reach is atypical due to presence of lowhead dam, but expect similar aquatic community throughout subsegment.
