Assessment Comments
Stream use assessment in Hardin County.
Basis for Assessment
Stream assessment form indicates above average habitat quality. A diversity of substrate types and several pool/riffle sequences observed. Isolated cases of channelization noted. Fairly good diversity of fish observed including game fish (n. pike and s.m. bass). The stream fish community may be enhanced as a result of direct linkage to Iowa River.
