Assessment Comments
Basis for Assessment
Changed assessment of support of the Class B(WW) aquatic life uses developed for the 1994 report (=PS) to FST due to occurrence of reaches within this subsegment that have significantly better habitat quality than the reach downstream. The entire reach of the E. Nishnabotna has certainly been impacted by extensive channelization, but the remaining meandered reachs--most of which are in this subsegment--provide the best aquatic habitat quality and recreational experience available in any river reach in the East Nishnabotna basin. The DNR float trips book (from mid-1980s) states that the reach of the East Nishnabotna from Elliot to south of Red Oak "offers some of the better fish habitat, especially for channel catfish, on the entire river."
