Basis for Assessment
Despite the lack of violations of Class B(LR) WQ criteria in monthly samples collected between Oct 1995 and Sept. 1997, continue to assess support of the Class B(LR) aquatic life uses as PS due to alterations to the aquatic habitat that have resulted from channelization and removal or riparian vegetation. The information upon which this assessment is based is more than 5 years old. Follow-up monitoring is needed to update this assessment and to better determine the status of the aquatic communities and habitats of this river reach.
