The Maine Warden Service reminds all that because of the previous two weeks of warm weather before the recent return to much colder temperatures, ice conditions around the state can be uncertain, and to use caution.

Corporal John MacDonald said there are some waterways that have seen ice open up or become thin, and he urged caution.

“It’s still a smart idea to check the ice as you go and watch out for currents that can undermine the conditions. Please — everyone — play it safe in spite of the cold weather returning.

Rivers and streams are of most concern, where water is constantly flowing and the warm weather has helped contribute to thin ice. And even with cold weather arriving this week it will be a while before ice conditions firm up on lakes as well, as thin spots have cropped up in some unusual places, according to wardens in the field.

In short, ice conditions remain questionable for much of the state and anyone venturing onto the ice, whether it be for snowmobiling, ice fishing, or just hiking or skating, is urged to use caution.
