* The warm air temperatures this weekend in the middle to upper 60s may cause people to underestimate the dangers of the cold water temperatures which are currently only around 50 degrees on Moosehead Lake and in the middle to upper 50s on smaller lakes and rivers. * The cold water temperatures can quickly cause hypothermia to anyone immersed in the water. According to the Maine Warden Service, when the water temperature is below 60 degrees, the average submerged person could lose dexterity within minutes and be unable to accomplish simple tasks. Anyone on small boats, canoes or kayaks should plan accordingly if recreating this weekend and use extreme caution to avoid this threat. Paddle smart from the start and always wear your life jacket!
