1 Water for Southern California: How Bay-Delta is Key to All of the Above Strategy Stephen N. Arakawa Manager, Bay-Delta Initiatives The Metropolitan Water District of Southern California October 15, 2016

2 California WaterFix: Securing Water Supplies for California Enhances supply reliability and Delta ecosystem Supports Southern California s local resources Modernizes the State Water Project and addresses flaws since its creation Protects billions of dollars of past investments made by Southern California 2 2

3 California s Current Drought Conditions US Drought Monitor As of October 11, 2016 US Drought Monitor As of October 13, 2015 Exceptional Drought 21% Extreme Drought 22% Severe Drought 20% Moderate Drought 21% Abnormally Dry 16% 3

4 Metropolitan Water District Regional water wholesaler 26 Member Agencies 6 counties Serving ~19 million residents 5,200 square mile service area $1 trillion economy 4 4

5 Bay-Delta: Critical Component of Metropolitan s Diverse Water Supplies Some regions 100% dependent on Bay-Delta supplies Southern California Water Portfolio 25% Colorado River Bay Area 33% Bay-Delta 30% State Water Project (through the Delta) Los Angeles Aqueduct 45% Local Supplies State Water Project Central Coast 37% Central Valley 23 to 90% Los Angeles Aqueduct Conservation Groundwater Recycling Metropolitan 30% Conservation, Local Groundwater, Recycling and Desalination Colorado River Aqueduct Desalination 5

6 Diversification of Water Portfolio (Average Year) Colorado (27%) State WP (33%) Conservation & Recycling (7%) Local Supply (34%) State WP (20%) Colorado (15%) Local Supply (32%) Conservation & Recycling (33%) Heavy dependence on imported supply and SWP Diversions Emphasis on Conservation, Local Supplies, and Storage & Transfers 6

7 Metropolitan s Water Portfolio: Supplies and Demand Management Recycling Groundwater Recharge Desalination Stormwater Management Colorado River State Water Project Conservation

8 Delta: Hub of California s Water Supply Supplies 25 million Californians with SWP water Provides irrigation for much of produce grown domestically 57 Islands and Tracts 700 miles of sloughs and channels 1,100 miles of levees

9 Impacts to California Statewide Bay Area Central Valley Central Coast Southern California Economy Global Statewide Regional Sectors Agriculture Environment Urban Contra Costa County Central Valley Silicon Valley Southern California

10 Water Flowing from Delta Watershed Upstream Consumptive Use 31% In-Delta Consumptive Use 4% Delta Exports 17% Metropolitan 4% Pacific Ocean 48% Source: Delta Vision Report (2007) Time Period: Estimated total annual runoff maf

11 Gold Rush Flood Control Agriculture Introduction of Non-Native Species Subsidence Urbanization Loss of Habitat Salinity Intrusion Sea-level Rise Earthquakes Fish Conflicts Highly-Altered Ecosystem

12 Chronic Impacts and Long-Term Risks State Water Project Supplies Chronic Impacts Fisheries conflict Pumping restrictions Non-native species Ag/Urban discharge Food web impacts Long-Term Risks Seismic Sea-level rise Subsidence

13 Sacramento/San Joaquin Bay-Delta Sacramento River/ West Delta Sacramento River Sacramento Stockton SWP Pumps San Joaquin River CVP Pumps 13

14 Diverse Alternatives Analyzed s s 1980s s Recent Various seawater barriers (Biemond Plan, Reber Plan, etc.) Chipps Island barrier Peripheral canal (21,800 cfs) Through-Delta Peripheral canal + SB200 Duke s Ditch (Through-Delta) South & North Delta Programs Bay Delta Accord CALFED Plan (~ 19 alternatives, storage, etc.) Post-CALFED Thru-Delta focus (>26 alternatives) BDCP - Multiple Initially Screened & 19 EIR/S Alts

15 2009 Delta Reform Act Comprehensive Delta Plan Co-equal Goals for the Delta Water supply reliability Ecosystem restoration

16 State s Proposal Protects State s water supplies through Delta system upgrades Dual tunnel facilities and mitigation Water-user funded Supports long-term health of native fish and wildlife Habitat restoration ~ 30,000 acres in 5 years Requires broader public funding 16

17 California WaterFix Additional Intakes Tunnels SWP Pumps CVP Pumps

18 18 Modernizing the State Water Project Designed to meet the state s mandated co-equal policy goals Water security Improved reliability Seismic safety Environmental protection Climate change adaptation Right size Cost Flexibility to capture flows during wet period runoff events Paid by water users ~$5/month/house (urban)

19 Sacramento River 100 mg/l California Water Fix Improved Water Quality SWP (Existing) 302 mg/l SWP (CA Water Fix) 221 mg/l (27% improvement) San Joaquin River 320 mg/l Colorado River 650 mg/l Sacramento, San Joaquin & Colorado River water quality represents historical average annual recorded data State Water Project water quality is comparison of modeled data from the Recirculated Draft EIR/EIS

20 State Water Project Essential Baseline for Southern California Drought reserves Groundwater replenishment Southland s highest quality supply Promotes recycling Helps manage salinity Diamond Valley Lake (100% SWP Water) 20

21 Metropolitan s Investments in Delta-Related Supplies State Water Project Construction Nearly 50 years of maintenance Diamond Valley Lake Inland Feeder Water treatment processes

22 Five Benefits for Los Angeles County Sustaining Our Cities Providing Local Groundwater Promoting Local Supplies Surviving Droughts Capturing the Storms

23 23 California WaterFix Key Decisions On the verge Environmental Documents Endangered Species Act Permits Approaching New Diversion Permit U.S. Army Corps of Engineers Permits

24 Know the facts Get involved What Can You Do? Promote the need for SWP/Delta solution Inform community and political leaders on significance of supply to region

25 Time for Action Benefits Advance statewide water reliability Protect Investments Minimize rate increases Modernize the system Protect groundwater basins Promotes local supplies Can t afford to delay Stephen N. Arakawa sarakawa@mwdh2o.com mwdh2o.com Bewaterwise.com
