Assessment Comments

Stream use assessment in 1992.

Basis for Assessment

Stream assessment form indicates fairly good habitat quality.  Some diversity of substrate and a few pool/riffle sequences observed.   Isolated cases of pasture use along stream corridor noted.   Moderate diversity of fish species observed.   Fish community dominated by generalist/tolerant species.   Estimated flow (0.5 cfs) was surprisingly low given the size of the watershed.   Losing stream?
