Integrating Water Management Defining California’s Water Challenges California’s Bay-Delta ecosystem is declining with 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.

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.
