LADWP Confirmed Mono Lake Elevation Is Rising
No Emergency Conditions Exist
Mono Basin continues to provide a much-needed water source for the City of Los Angeles as well as supports all of Southern California by easing the demand on other water supplies from the Colorado River and Sacramento-San Joaquin Bay Delta. Through LADWP, the City uses its Mono Basin water rights to serve safe, high quality drinking water to up to 200,000 Angelenos. The amount of water serving Los Angeles from Mono Basin, via the Los Angeles Aqueduct, has been reduced by 85%, or 70,000 acre-feet per year, since the State Water Resources Control Board (SWRCB) adopted Water Right Decision 1631 (D-1631) in 1994, limiting the amount of water that LADWP can draw from the Mono Basin.
Recent measurements taken at Mono Lake indicate that the lake level elevation is 6,379.3 feet above sea level, which is approximately two feet higher than its 2017 low of 6,377.5 feet. LADWP has also recently forecasted that snowfall in and around the Mono Basin will cause the lake level to rise approximately two more feet before the end of the year, ensuring the continued health of the Mono Basin ecosystem.
