Owens Lake held significant water until starting in 1913 the river and streams that fed Owens Lake were diverted by Los Angeles Department of Water and Power (LADWP) into the Los Angeles Aqueduct, and the lake level started to drop quickly. Some of the flow of the river has been restored, and the lake now contains some water. Before the diversion of the Owens River, Owens Lake was up to 12 miles (19 km) long and 8 miles (13 km) wide, covering an area of up to 108 square miles (280 km2). In the last few hundred years the lake had an average depth of 23 to 50 feet (7.0 to 15 m), and sometimes overflowed to the south upon which the water would flow into the Mojave Desert. Periodic winds stir up noxious alkali dust storms that carry away as much as four million tons (3.6 million metric tons) of dust from the lakebed each year, causing respiratory problems in nearby residents.
