The Iowa Department of Natural Resources (DNR) is implementing a 15-inch minimum length limit on all walleye captured from Rathbun Lake, starting Jan. 1, 2023.

All walleyes measuring less than 15 inches must be immediately released. Anglers can keep five walleyes per day. This regulation does not apply to the Chariton River below Rathbun Dam; the upper limit of the regulation will be the Wayne/Appanoose county line.
