The catch and release walleye season on Mille Lacs Lake has been set. The season will kick off Saturday May 13th and run through September 4th, Labor Day. However there is another catch — to help keep the walleye season open that long, the lake will have a 21-day walleye fishing closure from Friday, July 7 to July 27. During that 21-day period, anglers can fish for all other species in Mille Lacs Lake including bass, muskies and northerns but only with artificial bait and lures.
