The Winnebago River from the Minnesota state line down to Fertile has primarily a silty sand bottom. From the Fertile Dam to the confluence with the Shellrock River near Rockford, exposed bedrock is more prevalent. Anglers target primarily northern pike and sucker species in Winnebago and Hancock counties. In Worth, Cerro Gordo, and Floyd counties anglers also target walleye, channel catfish, and smallmouth bass.(2016)
