Where does the rain normally fall? `
14
Imported water supplies are stressed due to years of drought conditions. San Luis 43% 869 TAF Castaic Lake 64% 208 TAF DVL 69% 558 TAF LA SD Northern Sierra 7% Southern Sierra 18% Statewide 16% Oroville 50% 1.7 MAF Central Sierra 24% Statewide snowpack down to 16%,while major reservoirs stand at less than 50% filled. (05/27/2014)

Difference in Sierra snowpack Jan 2013 and Jan 2014

16 Green indicates groundwater levels that have increased. Red, orange, yellow are groundwater levels that have decreased.

All major state reservoirs in No. Calif. are well below capacity

19 For Southern California, investments in storage, capture, and efficiency have helped our supplies. Diamond Valley Lake, So. California’s newest reservoir, holds 810 TAF

Southern California’s Imported Water Demands Supply/Demand BalanceAcre-Feet SWP Supply600,000 CRA Supply1,200,000 Total Supply1,800,000 Total Demand2,000,000 In-Region Storage Requirement200,000
21
Conservation reduces storage depletion
23
Communicating the Drought People are distrustful of Government People realize that California has drought events – they also think they are “overblown” to justify rate increases People think they are conserving, and they ARE, we have reached a point where a few gallons helps the situation but won’t SOLVE the long-term problem The much touted upcoming “El Niño” may not generate usable precipitation
24
So we hope for this…
25
…but plan for this
