Assessment Comments

Stream use assessment.

Basis for Assessment

Stream assessment forms indicate above average habitat quality.  Diversity of substrates and several sequences of pools and riffles observed.   Good pool habitat to hold game fish species.  Stream is well-meandered with timber riparian vegetation.  Very good diversity of fish observed representing several trophic guilds.   Lack of flow stability is probably the major threat to integrity of aquatic community.
