Assessment Comments

Assessment is based on results of DNR monthly water quality monitoring NNW of Cambridge downstream from outfall of Ames WWTF.

Basis for Assessment

Used results of DNR monthly water quality monitoring near Cambridge, information from personal knowledge of this reach of river, and information from Harlan et al.  (1987: 10) to assess support of the Class B(LR) aquatic life uses as PS due to impacts of extensive channelization.  Although results of water quality monitoring show no violations of Class B(LR) water quality criteria over the two years of monthly monitoring, the degradation of aquatic habitat related to extensive channelization suggests that the Class B(LR) aquatic life uses are partially supported (PS).  See comments on assessment for the 1994 report and comments in Harlan et al.  (1987: 10).
