3. Metropolitan’s Service Area Diverse Water Supplies • Southern California Water Portfolio • 25% Colorado River • 30% State Water Project (through the Delta) • 45% Local Supplies • Los Angeles Aqueduct • Conservation • Groundwater • Recycling • Desalination Bay-Delta Los Angeles Aqueduct State Water Project Conservation,Local Groundwater and Recycling Colorado River Aqueduct

5. Water Supply Conditions Northern 39% May 11, 2014 Upper Colorado Basin 112% 52% Oroville 46% San Luis 42% 70% Lake Mead Diamond Valley

6. California relies on water that flows through the Delta Bay Area – 33% Central Valley – 23 to 90% Some regions 100% dependent Metropolitan – 30% 6

8. Delta: Hub of California’s Water Supply • 25 million Californians • Irrigation for much of the produce grown domestically • 57 Islands and Tracts • 700 miles of sloughs and channels • Unique manmade topography threatened • Seismic • Sea-level rise • Subsidence

9. Water Flowing from the Delta Watershed • Upstream Consumptive Use • Residential • Commercial • Agriculture • Industrial • Institutional In-Delta Consumptive Use4% Metropolitan 4% Delta Exports17% UpstreamConsumptive Use31% Pacific Ocean48% • Delta Exports • Central Valley Project • State Water Project Source: Delta Vision Report -Estimated total annual runoff 32.85 maf (2007) 9

12. Bay-Delta Conservation Plan • CONVEYANCE • Three intakes/pumping plants • State-of-the-art fish screens • Forebay temporarily stores water pumped from river • Two gravity flow tunnels (30 miles long; 9,000 cfs) Sac River Sacramento Sacramento Sac River North Diversion Stockton • REDUCING ENVIRONMENTAL STRESSORS • Toxic pollutants • Invasive species • Predator control • Illegal poaching • Hatchery practices Stockton • ECOSYSTEM RESTORATION • 56 species • ~150,000 acres SJ River SJ River SWP Pumps SWP Pumps CVP Pumps CVP Pumps South Diversion 12 12 Preliminary Subject to Preliminary Subject to Revision

13. Bay Delta Conservation Plan • Users pay for new conveyance facility & mitigation • Beneficiaries pay for habitat conservation & statewide benefits • $5 - 6/month per household for Southern Californians Metropolitan’s share is approximately 25 percent Estimated costs from BDCP Pubic Draft Chapter 8 (Dec 2013) in undiscounted 2012 dollars.

14. Statewide Economic Report—Costs/Benefits of BDCP • $5 billion in overall net benefits • 177,000 construction and habitat restoration jobs created • $84 billion in statewide business activity over 50-year life • Avoidance of water shortages that could cost over 1 million jobs
