Metropolitan provided $6 million in 2005 Managed by Volunteer Board Half of Funds Distributed Grants and loans Included small business development; job training programs MWD, PVID non-voting members Economic study concluded program is successful

MWD can store 1.5 million acre-feet in Lake Mead Avoids costs and impacts of building new storage reservoirs

Metropolitan, along with SDCWA, have implemented significant ag to urban transfers to help CA live within 4.4 MAF Apportionment New tools have been developed to help manage those supplies in dry years Lake Mead ICS, etc. The Colorado River faces continued challenges to its water supply reliability that will require new and innovative agreements and actions

Formed in 1905 Sustained by Ag drainage 50% Saltier than Ocean Salinity increase 1%/yr Soon too Salty for Fish Sea protected from QSA Transfer Impacts for 15 years IID to deliver 800 TAF of “mitigation water” to Salton Sea through 2017 Provided time for state to develop long-term solution

State has done little to advance Sea’s restoration Issued Draft EIR Preferred Alternative $9 billion, $100 million O&M IID petitioned SWRCB to condition QSA transfers on Salton Sea restoration Resources agencies hosting meetings with stakeholders

If consistent with restoration, mitigation water can be sold to DWR instead of delivered to Sea DWR, in turn, would sell water to MWD Proceed would benefit Salton Sea restoration $125 million of funds available Provide So. Cal. with up to 400,000 af, easing drought State of California would need to initiate this DFG Code provision

IID threatens to end transfers to SDCWA and CVWD without restoration plan If dust not sufficiently mitigated, lawsuits could block QSA transfers Working with QSA parties to encourage state to develop consensus Salton Sea solution
