  1. Statewide Integrated Water Management (IWM) Gary Bardini, Deputy Director IWM Rijkswaterstaat & CaliforniaCoordination Kickoff September 11, 2012

  2. Shasta Dam under construction Library of Congress Over the last century, water development in California has fueled economic vitality and made progress achievable.

  3. Statewide Hydrology

  10. Annual Operations of California’s Water System

  11. The Delta Estuary at the heart of the Californiawater system 74%Sacramento River Valley 8%In-Delta Uses 10%Eastside Tributaries /In-Delta Precipitation 65%Outflow to Suisun and San Francisco Bays 16%San Joaquin River = Sources of Water Into the Delta = Water Deliveries and Flow Out of the Delta 12%Central Valley Project, Mostly Agriculture Los Angeles 15%State Water Project, Mostly Southern California Urban and Industrial Use San Diego SOURCE: California Water: An LAO Primer, 2008

  12. 7.2 million Californians live in floodplains Statewide Total = 7.2 million

  13. Dam Safety St. Francis Dam Failure - 1928 ~450 fatalities 1,200 homes lost 10 bridges washed out

  14. Problems & Opportunities

  15. Snowpack Vulnerable to Climate Change • Flood Storage Sized Based on Rural Downstream Use CHALLENGES • Snowpack Vulnerable to Climate Change • Maximizing Storage of Spring Run • Balancing Water Transfer Market • Challenge to Fund Maintenance Activities • Restoring Riparian Habitat & NaturalRiver Functions • Achieving Natural Temperature & Flow Objectives • Ensuring Frequent Use of Floodplains • Making Use of Groundwater Recharge Basins • Making Use of Natural & Man-made System for Transfers • Reconnecting Floodplains • Limited Conveyance Capacity • Providing Flood Protection Relative to High Risk in Urban Areas • Providing Water Supply Reliability PUBLIC SAFETY PERSPECTIVE WATER MANAGEMENT PERSPECTIVE  ENVIRONMENT 

  16. Major system deficiencies put public safety, financial stability and economic well being of the State at risk of flooding. Defining California’s Water Challenges California’s Bay-Delta ecosystem is decliningwith many fish populations at record lows. Water supplies from the Delta are less reliable.Aging infrastructure and growing population put more pressure on water systems. Multi-year drought has further stressed water supplies for all purposes. Reservoirs are low and groundwater levels are declining. Climate change impacts, including less snowpack, higher flood peaks, and sea level rise, create new uncertainties.

  17. Values associated with water management activities include:

  18. Program Coordination Tracks • All programs work towards results in all three key values • Similar types of programs can also be grouped around common program coordination tracks

  19. Moving to Results • Public Safety • Environmental Stewardship • Economic Stability Results Tools Plans Actions • Plans … • Describe & inform future investment needs, they do not decide them. • Inform year by year how the state will support water management actions through the legislative process. • Document the value of previous investments & describe the potential value associated with future investments.

  20. Lining Up Programs for Interaction

  21. Examples of DWR Program Posters:
