Assessment Comments
Stream use assessment in Black Hawk County.
Basis for Assessment
Stream assessment form indicates fair habitat quality. Little diversity of substrate & few pool/riffle sequences observed. Isolated channel alterations noted probably associated with both agricultural and urban land uses. Frequent stream bank erosion observed is a symptom of susceptability to high flows. Fair diversity of fish species including a few smallmouth bass observed. Relatively few number of fish caught. Frequent sores or scars on suckers noted.
