Assessment Comments
Basis for Assessment
Class B fish consumption use not assessed due to lack of monitoring. No violations of Class B WQ criteria except for copper (2 of 8 samples= 25% viol) and mercury (7 of 9 samples =78% viol). Due to lack of known sources and due to analytical uncertainties, disregard metals data and assess Class B(WW) aquatic life uses as FST. DNR booklet "Iowa Float Trips" (DNR 1986?: 12-13) describes the numerous high quality areas for fishing in this reach, thus suggesting full support of the Class B(WW) aquatic life uses.
