When completely filled, Lake Powell's coastline is longer than the West Coast of the mainland United States, its sinuous shape outlining almost 2,000 miles of shore along the Arizona-Utah border. The 21st century has been hard on the nation's second-largest reservoir, though, with the southwestern megadrought leaving it below a quarter of its capacity at times (evidenced by the 'bathtub rings' visible here). Though popular for recreation, Lake Powell—and the Glen Canyon Dam that creates it—is a focus of debate: Many environmental groups say the lake should be drained to restore the Colorado River's natural flow.
