Lake Mead, which is actually the Colorado River backed up behind Hoover Dam, is the nation's largest man-made reservoir: it covers 225 square miles, is 110 miles long, and has an irregular shoreline that extends for 550 miles. You can get information about the lake's history, ecology, recreational opportunities, and the accommodations available along its shore at the Alan Bible Visitors Center. People come to Lake Mead primarily for boating, but a few areas or shoreline
are cultivated for swimming: Boulder Beach is the closest to Las Vegas, only a mile or so from the visitor center.
Angling and house boating are favorite pastimes; marinas strung along the Nevada shore rent houseboats, personal watercraft, and ski boats. At least 1 million fish are harvested from the lake every year including the popular striped and largemouth bass. It's stocked with rainbow trout on a weekly basis from late October through March. You can fish here 24 hours a day, year-round (except for posted closings). You must have a fishing license from either Nevada or Arizona (details are on the National Park Service website), and if you plan to catch and keep trout, a separate trout stamp is required. Willow Beach is a favorite for anglers looking to catch rainbow trout; Cathedral Cove and Katherine are good for bass fishing. Divers can explore the murk beneath, including the remains of a B-29 Superfortress, which crashed into the Overton Arm of the lake in 1948. Other activities abound, including waterskiing, sailboarding, canoeing, kayaking, and snorkeling.
