Basis for Assessment

Changed the assessment of support of the Class B(WW) aquatic life uses to "not assessed" due to (1) lack of recent water quality monitoring information (the most recent monitoring was conducted in August 1991) and (2) lack of biological information for this reach of river.   Additional monitoring is needed to determine the status of the aquatic communities and habitats in this reach of river.
