California’s Drought
• 2014 third dry water year statewide
• 2014 may be warm year on record
• Feb and Mar 2014 rain helped, but drought
conditions persist
• Statewide storage well below average
• Groundwater basins are being depleted
• Local conditions are degrading
• State and federal water projects restricted by
regulatory actions to protect the Delta
• High level of local, State and federal coordination
• 2015 could also be dry

Drought Impacts: Groundwater
• Spring 2010 – Spring 2014• Red - decrease of more than 10 ft• Orange - decrease of between
2.5 to 10 ft• Southern San Joaquin Valley Critical • Contributes to Subsidence• Increased Well Drilling• Deeper and Larger Wells• Small Communities / Homes
with dry wells

Drought Impacts• 5% SWP Allocation• 1,480 dry wells reported• Loss of Surface and Groundwater Sources• Fallow Crop Lands• Water Hauling to Small Communities and Individuals• Water Stations• Surface Water Curtailment (Urban, Power, Ag, Envro)• Conservation Targets and Enforcement• Increase Water Costs
D R O U G H T P R E P A R E D N E S S & R E S P O N S E
• Conservation and Education• Multi-agency Water Information
Management Systems• Local Drought Task Forces• Direct Water Hauling• Water Contingency Plans• Ground Water Assessments• Water Transfers (400 TAF)• Environmental Monitoring and Response
Short Term Actions
D R O U G H T P R E P A R E D N E S S & R E S P O N S E
Possible Drought Actions for 2015• Reduced Project Deliveries• Modified Delta Flow/Salinity Standards• State Water Board Curtailments• Drought Barrier Installation (one or more)• Mandatory Conservation• Increased Ground Water Use• Increased Oversight on Ground Water Use• Increased Mutual Aid• Increased Real-time Data and Information

D R O U G H T P R E P A R E D N E S S & R E S P O N S E
• Reliability • Conservation, Drought, Storage,
Regional Water Management & Groundwater Management
• Watershed/Water Quality• Flood Management• Delta Management & Operations • Sustainable Funding
California Water Action Plan
D R O U G H T P R E P A R E D N E S S & R E S P O N S E
Sustainable Groundwater Management• Key Element of the CWAP• Drought Impacts and Data Needed• Builds on Past and Current Efforts B 118 and CASGEM• Necessary to Address Needs and Completing Uses• Major step to address State’s Water
Budget
D R O U G H T P R E P A R E D N E S S & R E S P O N S E
Phased Approach
• Phase 1 – Realignment of Governance and Areas
• Phase 2 – Development and Adoption of GSPs
• Phase 3 – Early Implementation of GSPs with
Water Budgets
• Phase 4 – Sustainable GW Management
D R O U G H T P R E P A R E D N E S S & R E S P O N S E
Proposition 1 - $7.5B for actions to: improve water reliability and increase resiliency. • $2,700M Storage Projects• $520M Safe Drinking Water• $1,495M Environmental • $810M Effective Water Management• $725M Water Recycling• $900M Cleanup and Maintaining Groundwater• $395M for Flood Management

• 60-65 percent probability forming in the fall/winter.
• No strong correlation and above-normal
precipitation for interior Northern California

Thank You
The governor asked all Californians to reduce water consumption by 20 percent and referred residents and water agencies to the Save Our
Water campaign -- www.saveourh20.org
