The Southern California region’s water wholesaler joined with the federal government and agencies in Nevada and Arizona in an agreement aimed at dramatically cutting withdraws from the Colorado River and raising the water level in Lake Mead.
The Metropolitan Water District of Southern California was joined in the pact by the U.S. Bureau of Reclamation, the Central Arizona Project, Arizona Department of Water Resources and Southern Nevada Water Authority.
As part of the agreement, the agencies plan to contribute a combined $200 million for various projects aimed at reducing reliance on the drought-stricken Colorado River system. As a result, the 500+ Plan is aimed at preventing 1 million acre-feet of water from being drawn out of Lake Mead over the next two years.
According to the participating agencies, that amount of water is enough to serve 1.5 million households for a full year. Leaving that water in place would lift the water level of Lake Mead by 16 feet.
“Two decades of drought on the Colorado River is taking a toll across the Basin and on Lake Mead,” Bureau of Reclamation Commissioner Camille Calimlim Touton said in a statement. “By working together we’ve staved off these historic low levels for years, thanks to collaboration and conservation in the Lower Basin. But we need even more action, and we need it now.”
The pact is a follow-up to a 2019 agreement involving Arizona, Nevada and California known as the Lower Basin Drought Contingency Plan, or DCP, which was aimed at preventing Lake Mead from reaching dangerously low levels.
“We had hoped the contributions made under the DCP would be enough to stabilize Lake Mead while we seek longer-term solutions to the challenges on the Colorado River. But they aren’t, which is why we are moving forward with the 500+ Plan,” MWD General Manager Adel Hagekhalil said in a statement.
Under the pact, MWD will contribute $20 million toward projects aimed at protecting the lake. Central Arizona Project and Southern Nevada Water Authority will also each contribute $20 million, while the Arizona Department of Water Resources will commit $40 million. The Bureau of Reclamation will match all the donations, creating an overall funding pool of $200 million.
The money will fund a series of conservation programs, some of which officials said are already being implemented. The programs will include water-saving efforts in both urban and agricultural communities.
