Assessment Comments

Assessment is based on results of a September 1994 DNR stream use assessment.

Basis for Assessment

Used a review of the field sheet from the September 1994 DNR stream use assessment in Humboldt County to downgrade the assessment of support of the Class B(LR) aquatic life uses from FST to PS due to (1) very low fish community diversity (4 species from 2 families) for streams in the Des Moines Lobe subecoregion and (2) presence of less than a majority of the expected fish taxa (2 of 11) for streams in this subregion.   Although the sampling of the fish community was negatively affected by large rocks and other debris in the stream, the low diversity suggests that follow-up monitoring should be conducted to better determine the status of the aquatic communities and habitats and to determine whether the Class B(LR) aquatic life uses are impaired.   The field sheet does not indicate any significant impacts to the physical characteristics of this stream.
