ST. PAUL, Minn. (AP) - The Department of Natural Resources is closing Mille Lacs Lake for walleye fishing at 10 p.m. on Monday.

Minnesota natural resources officials said Sunday that anglers had exceeded the central Minnesota lake's walleye quota by 2,000 pounds. The department stresses that other fish species like bass, northern and muskies are still plentiful in the lake.

The walleye population at Mille Lacs Lakes has dropped to a 30-year low, leading the state to impose quotas.

Department of Natural Resources Commissioner Tom Landwehr says closing the lake is necessary to protect the walleye population.

That dipping population has become a topic of conversation among Minnesota politicians. Gov. Mark Dayton says a special session of the Legislature is necessary to aid area resorts and businesses bracing for a drop in tourism.
