Assessment Comments

Stream use assessments in 1990 and 1992.

Basis for Assessment

Stream assessment forms indicate above average habitat quality.  Some diversity of substrate and several pool/riffle sequences observed.   Woody debris, root wads, and undercut banks enhance quality of habitat.   Good pool depth noted.   Lack of low flow stability may be a threat to integrity of aquatic community.  Rel.  good diversity of fish species observed including game fish.  Lake may be augmenting stream fish community.
