Before heading out on the water this week, check the temperature.

The United States Coast Guard warns residents that the Great Lakes waters are cold. 

Water temperature that is below 77 degrees is considered dangerous and capable of quickly causing hypothermia, according to a statement from the U.S. Coast Guard 9th District of the Great Lakes.

"The maritime environment can be dangerously unpredictable and can lead to unexpected entry into the water," and unexpected entry can lead to drowning, according to the Cost Guard. 

Residents are advised to dress for the water temperature and not the air temperature, in addition to wearing a life jacket.

Having a plan can be essential. Boaters should tell someone trustworthy on land about boating plans, where you plan to go and for approximately how long, the Coast Guard said. "Having a point to start a search from can make the difference between a successful or unsuccessful rescue."
