Abstract

In the last twenty years, the Iowa State Conservation Commission has dredged a number of shallow prairie lakes to enhance their recreational value. North Twin Lake, Calhoun County, was partially deepened by dredging in 1939. This lake, approximately 569 acres in area, now supports considerable boating, swimming, and fishing. In 1951 the Iowa Cooperative Fisheries Research Unit started a comparative study of the bottom fauna in the dredged and undredged portions of the lake. To determine the degree to which the various bottom organisms were being utilized as fish foods, the food habits of the more important fish species inhabiting North Twin Lake were investigated during the summers of 1953 and 1954.
