Assessment Comments

Assessment is based on results of 1995 biocriteria sampling: habscr/fshscr = 25/12 (shock).

Basis for Assessment

Used a review of results from the August 1995 biocriteria sampling to upgrade the assessment of support of the Class B(CW) aquatic life uses from FST to FS due to presence of the expected coldwater species (brown trout), with large adults present.   In addition, this stream reach supports a relatively diverse fish community (19 species from 5 families) and the riparian corridor is in good condition.
