Assessment Comments

Two stream use assessments.

Basis for Assessment

Stream assessment forms indicate well-above average habitat quality.   Diverse substrate and several pool/riffle sequences observed.   Good pool depth should sustain aquatic community during dry periods.   Channelization and pasture use impacts in headwaters are a threat to integrity of aquatic community.   Fairly good diversity of fish species observed for a small stream in this region.
