Members of the Coast Guard are using mannequins as part of a search and rescue field exercise being conducted offshore of Red River Park.
During the exercise, 20 mannequins will be strategically placed and used to simulate persons in distress either in the water or on the ice. The general public is asked to not disturb the mannequins.
A 22-foot airboat and MH-65C rescue helicopter will be used during the exercise, which will take place during both the daytime and nighttime hours through February 21.
The Ice Sweep Width Study is being conducted to gather information and data that will be used to assist search and rescue responders on the Great Lakes, and for the purpose of decreasing the time needed to locate and reach a person in distress.
