This 57-mile stretch of river starts below lower dam about 11 miles northeast of Decorah and gently flows through many remote scenic areas before emptying into the Mississippi River. The last 8.6 miles of river are channelized and has a sandy silt bottom. There are no dams to portage around in this section. There are many great access points from below lower dam to Hwy 76 bridge and a multitude of outstanding holes to fish between each. During the summer months, anglers should concentrate efforts around the mouths any number of cold water tributaries that empty into the river. Anglers should have no problem catching Smallmouth Bass, Walleye, Northern Pike, Rainbow Trout, and Brown Trout. The best way to get around this section of river is by canoe, kayak, or small johnboat powered by shallow drive motor.(2022)
