3 The Mission of the Metropolitan Water District is to provide its service area with adequate and reliable supplies of high-quality water to meet present and future needs in an environmentally and economically responsible way.

4 Regional Water Wholesaler to 6 counties 5,200 square miles 26 Member Agencies ~19 million residents Regional economy: $1 trillion Retail demand 2009: 4 million acre-feet Provided about ½ of retail demands

5 One Acre-Foot: - covers 1 acre of land 1 foot deep - equals ~326,000 gallons - supplies roughly six to seven people for one year

6 Sierra Nevada Mountains Bay-Delta State Water Project Local Groundwater, Surface & Recycling, Los Angeles Aqueducts Colorado River Aqueduct Conservation

7 SWP (West Branch) SWP (East Branch) N CRA Major N MWD Facilities: 242 miles of aqueduct 775 miles of pipelines 7 major pumping stations 5 water treatment plants 16 hydroelectric plants Treatment Plants: Ranging from 326 to 750 MGD Average system flow ~ 2 BGD

10 Storage & Transfers CRA Cons Local Supplies SWP Storage & Transfers Conservation & WUE CRA SWP Local Supplies Heavy dependence on imported supply and SWP Diversions Emphasis on Conservation, Local Supplies, and Storage & Transfers

11 Blueprint for Adapting to Change Component 1: Core Resource Strategy Component 2: Supply Buffer Component 3: Foundational Actions Reliability Under Planned Conditions 20x2020 Retail Conservation Fix the Delta Develop Dry-Year CRA Programs Develop additional Local Projects (eg. Historical weather) Adapt to Shorter- Term Uncertainty 20x2020 Regional Targets Collaborative Local Development Water Transfers (Outside of planned conditions) Preparation for Long- Term Change Implement Low Regret Actions Monitor Development Progress in Core Resources Initiate Adaptive Resource Options if Conditions Warrant (Climate Change, Supply Loss, Demands)
