Assessment Comments

Stream use assessment.

Basis for Assessment

Continued to use the assessment of support of the Class B(LR) aquatic life uses developed for the 1994 report (=PS).   Reports from the public suggest that the stream may be subject to occassional fish kills.   Follow-up monitoring is needed to identify the status of aquatic communities and habitats and to determine the degree to which the Class B(LR) uses may be impaired.
