Lake Mead Water Level at Hoover Dam

Annual time series of the water level of Lake Mead at Hoover Dam. Water levels in Lake Mead have varied widely over the years. Low levels in the 1950s and 1960s were due to drought and the filling of Lake Powell, respectively. Recent years have seen the lowest recorded levels since Lake Mead levels dipped in the 1950s. The red-dashed line indicates the threshold (1,075 feet) below which a federal shortage will be declared, resulting in reduced water allocations for Nevada and Arizona. Source: USBR and NPS.
