    1. NorthwestHydroelectricAssociation2011 Annual Conference Dave SamsonCA Department of Water Resources "Avoiding a Dam Midlife Crisis" THE CALIFORNIASTATE WATER PROJECT

    2. DWR MISSION To manage the water resources of California in collaboration with others to benefit the State’s people, and to protect, restore, and enhance the natural and human environment.

    3. DWR’s Strategic Planning Goals — • California Water Plan • State Water Project • Ecosystem Protection (Bay-Delta) • Flood Control & Dam Safety • Water Use Efficiency (Public Education) • Regional Water Management Planning • State Long-term Power Contracts • Professional Services

    4. SWP PURPOSE 75% of the water supply captured in northern region of the state 80% of the water demand is in the mid and southern region

    5. SWP FACTS 1960: Voters approved $1.76 billion bond sale to construct facilities. Planned, designed, built, operated and maintained by the California Department of Water Resources. SWP is the largest state-built multipurpose water project in the U.S.

    6. SWP FACTS SWP is the single largest power consumer in California. (8 million MWh annually) SWP is the fourth largest power generator in California. Installed generating capacity is ~1,500MW.

    7. SWP FACTS • State Water Contractors • 29 water contractors (Local public agencies) • 750,000 acres of irrigated crops • Drinking water for 25 million people • SWP Water Deliveries • Total water supply contracts of 4.2 MAF • Delivery average is approximately 2.6 MAF 70% M&I 30% Agriculture

    8. CALIFORNIA STATE WATER PROJECT • SWP Facilities • 34 storage facilities • 29 pumping and generating plants (189 Units) • ~700 miles of canals and pipelines • SWP Operations • Project Operations Center • Field Divisions • SWP Maintenance • Field Divisions • Headquarters Support OROVILLE FIELD DIVISION DELTA FIELD DIVISION SAN LUIS FIELD DIVISION SAN JOAQUIN FIELD DIVISION SOUTHERN FIELD DIVISION

    9. SWP PROFILE

    10. SWP Features • Oroville Dam • 3.5 M Acre Feet • 700 Ft Zoned Earthen Embankment • (Tallest earth fill dam in U.S.)

    11. SWP Features • A.D. Edmonston Pumping Plant • 14 – 80,000 HP • Vertical Turbine Pumps • 1924 ft. (static) LiftHighest pump liftin U.S.

    12. SWP Features • California Aqueduct Check Structure

    13. SWP Challenges • RETAINING A WELL-QUALIFIED WORKFORCE • OPERATIONAL RELIABILITY • GOVERNANCE

    14. SWP Challenges RETAINING A WELL-QUALIFIED WORKFORCE • Employee Turnover • Employee Experience • Compensation Lag

    15. Employee Turnover Trends Retaining a Well-Qualified Workforce

    16. Retaining a Well-Qualified Workforce Employee Experience

    17. Retaining a Well-Qualified Workforce B.U. 12 Compensation Lag 2009 Data

    18. SWP Challenges OPERATIONAL RELIABILITY • Operational Availability • Aging (& Missing !) Infrastructure

    19. Operational Availability All SWP Pumping and Generating Units OA = Percent of time facilities are available for use

    20. SWP Challenges AGING INFRASTRUCTURE • Facilities Approaching 50 years • 3 “Rs” • Refurbish • Replace • Remediate

    21. SWP Challenges MISSING INFRASTRUCTURE • Delta Conveyance

    22. Delta Conveyance

    23. Delta ConveyanceMissing Link

    24. SWP Challenges GOVERNANCE • SWP is a Water Utility • Administrative Constraints of State Government • California’s Financial Crisis

    25. "Avoiding a Dam Midlife Crisis" THE CALIFORNIASTATE WATER PROJECT • California’s current population is more than 36 million • The population is expected to reach 50 million by 2020 • Largest agricultural production in the nation • No imminent fix of California’s governance in sight!
