Stream use assessment.
Basis for Assessment
Stream assessment form indicates above average habitat for small stream in this region. Coarse substrates, pool & riffle habitat observed to support a good diversity of headwater fish species. Relatively low diversity and especially numbers of fish observed. Suspect a water toxicity problem but source unknown. Only species with more than three individuals were the relatively pollution tolerant bluntnose minnow and creek chub; approximately 20 individuals of each of these species were collected.
