  1. The Kern Water Summit Breaking Bad: The Challenge of Aging Infrastructure Dams, Levees and Groundwater March 6, 2018 By David Gutierrez, Vice President GEI Consultants Presented by the Water Association of Kern County

  2. Quenching a Thirsty State

  3. California’s Vast Intertied Water System • Dams • Levees • Groundwater • Other • Pipelines • Canals • Desal Plants

  4. California Dams Lower Crystal Springs - 1888 O’Shaughnessy Dam - Hetch Hetchy Valley - 1923

  5. Inventory of California Dams – Dams Constructed by Decade 20th Century From California Division of Safety of Dams

  6. California Dam Failures and Incidents St. Francis Dam Failure - 1928 Oroville Dam - 2017

  7. Repairing Old Dams Calaveras Dam - 1917 • DSOD established in 1929 • Additional laws after: • Lower San Fernando • Baldwin Hills • Oroville Calaveras Dam - 2019

  8. California Levees Sacramento Valley Delta San Joaquin Valley Southern California

  9. Construction of Central Valley Levees

  10. California Levees Failures and Problems • Flooding • Subsidence • Earthquakes • Climate Change • Southern California Water Supply

  11. California Levees - The Perfect Storm

  12. The Importance of Groundwater • 38% of total water supply (statewide average) • 60% during drought years • Many communities are 100% reliant upon GW 2005-2010 Average Data

  13. Adverse Impacts Lowering of GW Levels Reduction of GW Storage Seawater Intrusion Depletion of Interconnected Streams Water Quality Degradation Land Subsidence

  14. The Groundwater Sustainability Program • 515 Groundwater Basins and Subbasins

  15. Discussion Points • Out of Site – Out of Mind • Water Infrastructure is aged! • Structures are aging and therefore crumbling • Structures are designed to yesterday’s standards • Often segmented system • Lack of constant and consistent funding • Permits and time to make improvements
