Under the nation's largest ag-to-urban water conservation transfer agreement (called the Quantification Settlement Agreement, a series of pacts between California water districts to help California live within its 4.4 million acre-foot entitlement right of Colorado River water), since 2003 water has been, and continues to be, released to the Salton Sea to mitigate negative environmental impacts. But the agreement calls for this for the first 15 years of the water transfer. (Water conserved on Imperial Valley farms and in the IID water delivery system is provided to Southern California coastal communities—specifically the San Diego County Water Authority, the Coachella Valley Water District and the Metropolitan Water District of Southern California). This flow of mitigation water to the sea will end on Dec. 31, 2017. To date, the State of California has not lived up to its obligation to develop a restoration plan for the sea.
