The DNR Division of Trails and Waterways is making a special effort to ensure all DNR boat launches are ready by the opener, said Nancy Steward, the Public Water Access Program coordinator. She noted, however, that repairs to access sites depend on the weather and ice-out, which has been running two weeks behind normal.

"Some lakes in the northern half of the state may still have ice, which poses a challenge in making repairs," Steward said. "It's wise for boaters to check ahead for the latest report on the access they plan to use."

Winter weather is always a challenge to Minnesota's public water access, Steward said. As ice expands during the winter months, it can push and buckle the concrete plank structures like an accordion.

This phenomenon, called "ice jacking," is caused by the pushing action of a lake's ice sheet against the shore, which often leaves the boat ramp unusable. Crews repair damaged boat ramps by removing damaged planks and replacing them with new ones.

Steward said anglers should plan to be patient and prepared at public water accesses and use extra care while launching and loading boats this weekend.

They also should inspect the ramp condition before using it; some of the worst ramp damage can be below the water line.
