Boaters could find problems at some public water accesses on Saturday, thanks to the late spring.
Some boat ramps might not be usable, and some docks might not be installed by Saturday, Department of Natural Resources officials said this week.
"The late ice-out is causing us problems this spring," said Nancy Steward, the DNR's public water access program coordinator.
Most accesses in the southern half of the state will be in good condition and open for use, she said.
"Some lakes in the northern half of the state may still have ice, which poses a challenge in making repairs," she said.
Steward said boaters should check ahead first, and have alternative plans -- just in case.
Boat accesses can be damaged over the winter by shifting ice.
"Some may be fine, and some may be unusable," she said. "Normally the ice goes out, they fix it, and nobody knows [it was a problem]."
