Stream use assessments.

Basis for Assessment

Continue to use the assessment of support of the Class B(LR) aquatic life uses developed for the 1996 report (=PS).   Follow-up monitoring is needed to determine the status of the aquatic communities and habitats and to determine the degree to which the Class B(LR) uses may be impaired.  Because the data upon which this assessment is based are more than 5 years old, changed the 305(b) assessment category from "monitored" to "evaluated."
