Integrated Data and Analysis to Support the California Water Plan
1
Vision & Purposefor Analytical Tool and Data Improvements
Support decision making in light of uncertaintiesoPromote collaborative decision making,
Shared Vision Planning
Support integrated water management regionally and statewideoSupply reliability, flood management,
environmental restoration, water quality, economic efficiency, social equity
2
Information and Modeling Needs
Information gaps and limitationso Land use, groundwater balances, local
diversions, environmental conditions
4 examples of technically challenging problemso Integrated regional water managemento Integrated flood managementoEcosystem restorationoAdapting to climate change
3
Water Plan Quantitative Deliverables
Accurately describe recent water management conditions (Water Portfolios)
Develop multiple baseline future conditions (Scenarios)
Identify alternative water management response packages (management strategies)
Evaluate performance of strategies in terms of benefits, costs, and tradeoffs
Evaluate interaction between local, regional, and statewide water management
Support Water Planning Information Exchange
4
Water Plan team is developing tools to quantify costs, benefits, tradeoffs
Represent physical water management system
Quantify strategy benefits
5
Some Limitations
More comprehensive look at three regions in Central Valley
Cannot represent all strategies
Cannot quantify all strategy benefits
Coarse representation of regional groundwater system
