California Water Management Issues

• Current Challenges
• Statewide water conditions
• Water supply reductions
• Delta
• Ecosystem health
• Seismic risk
• Sea level rise
• Regulatory actions
• Climate Change
• Snowpack reduction
• Flood flows

Current Statewide Water Conditions

• Reservoir Storage
• About 80 of average to date in major on-stream
  reservoirs
• Precipitation
• About 85 of average to date
• Runoff
• About 55 of average to date
• Snowpack
• About 100 of April 1 average for water content
• Long-Range Conditions
• Water year outlook 65 due to extremely dry
  conditions in fall of 2007

4
Estimated 2008 Water Supply Reductions

• State Water Project Contract Allocation
• 35 with Delta pumping restrictions
• Total SWP Water Supply Losses Due
  to Delta Pumping Restrictions
• Approximately 450,000 acre-feet

Environmental Studies

• BDCP will evaluate alternatives necessary to
  restore and protect the Delta ecosystem in the
  context of options for water conveyance
• The BDCP will include a wide range of
  conservation actions including
• Protected and restored habitat
• Improved water quality
• Control of invasive species
• Better protection of resident and anadromous fish

8
Environmental Studies

• Alternative Conveyance Options
• No new Delta conveyance
• Dual conveyance
• Isolated facility
• Through Delta solution
• Plus alternatives which may result from scoping

Interim Actions

• Types of actions that are underway
• Ecosystem restoration
• Water supply reliability
• Water quality
• Levee stability

12
Need for Water Storage in California

• Added flexibility to decrease conflict between
  water uses
• Adaptation to climate change
• Changing water needs
• Dry year / drought needs
• Emergency storage needs
• Complements other programs statewide

13
Integrated Regional Water Management

• Conservation
• Increased storage
• Water recycling
• Conjunctive management
• Groundwater cleanup
• Floodplain preservation
• Watershed management
