Stream use assessment near Black Hawk/Butler co line.
Basis for Assessment
Stream assessment form indicates fair habitat quality for B(WW) stream in this region. Sandy run habitat was most dominant type observed. Best cover for fish consisted of numerous woody debris snags. Rel. good riparian conditions and meandering stream channel are also positive attributes. Frequent stream bank erosion noted is a symptom of susceptability to high flow. Fair diversity of fish observed, but generally low numbers of fish caught. Size of stream and turbidity may have reduced sampling effectiveness. Data from quarterly monitoring station shows no violations of Class B(WW) WQS.
