Lake Mead National Recreation Area, which celebrated its 61st birthday August 11, attracts almost 8 million visitors a year. Nearly all return home safely with fond memories of fun on or in the park’s two huge lakes. Accidents do happen, though, and nearly always because people violate commonsense safety rules.
