This twenty six mile stretch of river in Butler County from the town of Greene downstream to the community of Shell Rock is a must for any angler. This river offers bountiful and robust smallmouth bass and walleye! An electrofishing survey conducted by staff in the fall of 2015 sampled 47 walleye per hour with one walleye measuring 30.2 inches in length and weighing 9.92 pounds! This fishery has greatly benefitted from the IA. DNR interior walleye stocking program. Many trophy sized smallmouth bass can be caught along with an occasional musky that has escaped from Clear Lake, moved down the Winnebago River into the Shell Rock River. Channel catfish populations tend to be lower in numbers but they are of preferred to memorable size with some catfish approaching thirty inches in length. Navigation is best by a kayak, canoe or small jonboat powered with a shallow drive motor. There are two hard surface boat ramps recommended, Camp Comfort County Park (4 mi S. of Greene) and Heary Woods State Park south of Clarksville. Boaters whom launch at these sites must motor up-river as there are obstacles (low-head riffle and dam) at both of these areas. There is a gravel access located below the boulder riffle at the Camp Comfort County Park and a hard surface boat ramp located on the east side of the river below the dam at Shell Rock. (2016)
