At least nine more people were reported breaking through thin ice on snowmobiles in the 24 hours after an incident on Mount Desert Island.
Including an accident in Denmark, where Stephen Glasglow, 44, and his 5-year-old daughter encountered a flooded portion of a snowmobile trail.
Both were submerged in the icy water, but escaped and managed to call for help.
Both had signs of hypothermia when a game warden located them and were transported to Bridgton Hospital for treatment.
Two other close calls happened in Belgrade and Sangerville in that time.
Wardens said rain and warm temperatures have worsened ice conditions statewide and that the return of cold temperatures should not relax the need for extreme caution out on the water.
