Abstract | Differences in certain physical factors, bottom fauna and fish populations were evaluated in channelized and unchannelized portions of the Little Sioux River, Iowa, during 1969-71. Little Sioux River is a turbid, warmwater river located in western Iowa. Characteristic stream channels were a meandering, non-uniform channel with heavy vegetative cover in the unchannelized section; and a straight channel with relatively uniform depth and no heavy vegetative cover in the channelized section.
