Assessment Comments
Assessment is based on results of fish tissue (RAFT) monitoring in 1995.
Basis for Assessment
Had no violations of Class B(WW) WQ criteria in five samples collected by USGS during water year 1993 at the Hamburg monitoring station; station discontinued by USGS after the 1993 water year. All levels of contaminants in sample of carp fillets collected for the 1995 RAFT program were less than 1/2 the FDA action levels. Account in "Iowa Float Trips" states that the Nishnabotna remains channelized throughout.
