The walleye bite has picked up on the Shell Rock River in Butler County this past week.
Walleye - Good: Anglers have been doing best casting and retrieving lead head jigs tipped with plastics. Evening fishing has been the most productive.

This 26-mile stretch of river in Butler County from 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 2020 collected a total of seventy walleye with 30% of those being fifteen inches or greater in length. This fishery has greatly benefited from the IA DNR interior walleye stocking program. Good numbers of smallmouth bass can be caught along with an occasional musky that has escaped from Clear Lake and moved down the Winnebago River into the Shell Rock River. Channel catfish populations are lower in numbers, but are of preferred to memorable size with some catfish approaching 30-inches long. Navigation is best by a kayak, canoe or small jon boat powered with a shallow drive motor. There are two hard surface boat ramps recommended, Camp Comfort County Park (4 miles south 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 below the boulder riffle at the Camp Comfort County Park and a hard surface boat ramp on the east side of the river below the dam at Shell Rock.(2020)

The vast majority of Iowa’s streams, rivers and lakes offer safe and high-quality fish that pose little or no threat to human health if consumed. Some limitations may apply for young children and pregnant women. Here’s a Fish Consumption Fact Sheet from the Iowa DNR and the Iowa Dept. of Public Health for more information.
