Water Supply Risks to Metropolitan Agriculture demand could grow along the Colorado River PVID: 16, 000 additional mesa acres CRIT: ~50, 000 AF of unused water rights Other areas could grow Water use increases would affect MWD’s supply Options to address increases include expanded fallowing, purchasing land

Lake Mead’s Future in Average Years

Augmentation? Conservation?

Summery 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

Issue #3: Uncertain Future of the Salton Sea

QSA Provided Time to Restore Salton Sea 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

Frequent Fish Kills on Salton Sea

15 Year Period Nearing End; No Action Taken to Save Salton Sea 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

QSA Legislation Authorized Potential Funding Source 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

Salton Sea Risks to QSA 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
