11 2008 Drought Impacts Agricultural losses Local rationing Delayed economic development Reduced hydropower generation Reduced recreation Increased wildfire Small systems at risk Lake Oroville 10

12 Projected Economic Impacts of Drought in 2009 Current UC Davis projections 2009 job loss 60,000-95, income loss $ billion Farm revenue loss $ billion 11

13 Water Shortage The New Normal? Climate Change Effects: Diminishing snowpack More extreme weather patterns Rising sea level Higher air/water temperatures affecting ecosystem health 12

14 Climate Change and Snowpack 25% loss of snowpack by 2050 that s 5 million acre-feet per year 13

15 Drought Response What Can We Do About It? Short-term Actions Help communities cope with water shortages this year Long-term Actions Help California prepare for future shortages 14

16 Drought Emergency Proclamation Emergency Proclamation February 2009 Expedites drought water bank/other transfers Calls for immediate conservation and statewide campaign Requires state agency water use reduction Mobilizing CAL-EMA drought response actions Trigger emergency exemptions in CEQA for priority drought relief projects Fish protection and water quality actions in Delta Calls for permit streamlining for emergency supply projects 15
