The Mathews County Visitor Information Center is reminding paddlers and others heading out on the water that the Chesapeake Bay and its rivers and creeks can be life-threatening to those who are unprepared. Air and water temperatures are not the same. According to the U.S. Coast Guard, April is the second-deadliest month for paddling accidents. The advice is to read up on recommendations before getting outdoors, and remember the dangers of the cold water.
