PORTLAND, Maine (AP) — Maine wildlife officials say it’s time to pack up the ice fishing shacks for the spring.

Wednesday is the day fishermen must remove the shacks from all lakes and ponds. Officials say portable shelters are still allowed.

State Department of Inland Fisheries & Wildlife spokesman Mark Latti says it is still legal to ice fish on many waterways throughout the state, where lots of lakes and ponds remain frozen. He advises that fishermen check the safety of the ice before attempting to fish by chiseling or drilling holes and measuring the thickness.
