Defining California’s Water Challenges
California’s Bay-Delta ecosystem is decliningwith many fish populations at record lows.
Water supplies from the Delta are less reliable.Aging infrastructure and growing population put more pressure on water systems.
Multi-year drought has further stressed water supplies for all purposes. Reservoirs are low and groundwater levels are declining.
Climate change impacts, including less snowpack, higher flood peaks, and sea level rise, create new uncertainties.
Major system deficiencies put public safety, financial stability and economic well being of the State at risk of flooding.

Values associated with water management activities include:
Integrating Water Management
Program Coordination Tracks• All programs work towards
results in all three key values• Similar types of programs can
also be grouped around common program coordination tracks
Integrating Water Management
Moving to Results
Plans …• Describe & inform future investment needs, they do not decide
them.• Inform year by year how the state will support water
management actions through the legislative process.• Document the value of previous investments & describe the
potential value associated with future investments.
