MWD, PVID non‐voting membersEconomic study concluded program is successful
Nevada’s water use has dropped over past decadeMWD has access to NV’s unused water during current droughtMWD to return water when Nevada’s demands grow
MWD can store 1.5 million acre‐feet in Lake Mead
Avoids costs and impacts of building new storage reservoirs

To date, state has done little to advance Sea’s restoration

IID to deliver 800 TAF of “mitigation water” to Salton Sea through 2017Provided 15 years for state to develop long‐term solution
If consistent with restoration, mitigation water can be sold to DWR instead of delivered to SeaDWR, in turn, would sell water to MWDProceed would benefit Salton Sea restoration
$125 million of funds availableProvide So. Cal. with up to 400,000 af, easing drought
State of California would need to initiate this DFG Code provision
Colorado River Supplies have been critical in dealing with current drought
Colorado River faces two looming challenges:
River is over‐allocated and not sustainable for current demands
A long‐term solution to the Salton Sea is needed to avoid water conflicts in California
Collaboration with other agencies will be needed to address challenges
