en.Wedoany.com Reported - California, Arizona, and Nevada have signed a new water-sharing agreement that allows Nevada and Arizona to use water from the San Diego desalination plant under certain conditions. The plant, operated by the San Diego County Water Authority, has a daily capacity of 54 million gallons.

In years when San Diego has surplus water, the proposed project would allow California to transfer its Colorado River water rights to other states. Prolonged drought has reduced storage in the Colorado River system to about 36% of capacity, and declining water levels also threaten hydropower generation in the region, according to data from the U.S. Bureau of Reclamation.

The plan does not involve transporting water directly from the desalination plant to Lake Mead but instead establishes a system of "paper" transfers and credits to help stabilize Lake Mead during water shortages. This project would be the first to transfer Colorado River basin water resources across state lines.
