Assessment Comments

Stream use assessment.

Basis for Assessment

Stream assessment form indicates below average hab quality.   Little diversity of substrate and few pool/riffle sequences observed.  Silt and sand substr.  are dominant.   Frequent pasture use impacts including frequent str.  bank erosion and stream widening noted.  Extensive channeliz.  in headwater reaches of stream and tribs.  Fairly good diversity of fish observed.   Under more stressful conditions, stream may not support existing fish community.
