Snowpack Vulnerable to Climate Change • Flood Storage Sized Based on Rural Downstream Use CHALLENGES • Snowpack Vulnerable to Climate Change • Maximizing Storage of Spring Run • Balancing Water Transfer Market • Challenge to Fund Maintenance Activities • Restoring Riparian Habitat & NaturalRiver Functions • Achieving Natural Temperature & Flow Objectives • Ensuring Frequent Use of Floodplains • Making Use of Groundwater Recharge Basins • Making Use of Natural & Man-made System for Transfers • Reconnecting Floodplains • Limited Conveyance Capacity • Providing Flood Protection Relative to High Risk in Urban Areas • Providing Water Supply Reliability PUBLIC SAFETY PERSPECTIVE WATER MANAGEMENT PERSPECTIVE ENVIRONMENT
Major system deficiencies put public safety, financial stability and economic well being of the State at risk of flooding. 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.
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
Moving to Results • Public Safety • Environmental Stewardship • Economic Stability Results Tools Plans Actions • 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.
