3 3 Part 1 – Preparing the Plan Water Plan Update Overview & Process New Planning Framework Limitations & Phased Work Plan Content & Document Organization Key Themes, Findings & Recd Actions

4 4 Water Plan Overview Program 10 > 1 of 6 DWR Goals Required by law (Water Code) First Water Plan -Bulletin 3 (1957) Seven Updates (Bulletin 160) Update every five years –Last in 1998Next in 2003 States Master or Strategic Plan

5 5 California Water Plan Purpose –Strategic plan for state policy/decision makers –Guide for managing & developing CA water –Framework for investing public funds Content –Basic information - water resources & system –Current water supplies and uses –Scenarios for future supplies and use –Recommendations (Strategies & State Role) Footnotes –No mandates; No spending authorizations –Not project or site specific; No CEQA

6 6 Water Plan Update 2003 DWR Goals & Approach Goals –Meet Water Code requirements –Expand public input –Develop a useful plan Approach –Open & transparent public process –Seek collaborative recommendations –Strategic Planning model; New framework

17 17 Water Plan Vision for 2030 California has adequate, reliable and sustainable water of suitable quality for all beneficial uses.

18 18 Water Plan Goals for 2030 Improved quality of life for projected 53 million Californians. Sustained economic growth, business vitality and agricultural industry. Protected and restored ecosystems. Environmental justice for all Californians. Stronger State leadership, coordination, and oversight and more public investment. Regions play the central role in integrated water & resource planning. Local and regional planners diversify management strategies. Local govmts and agencies improve coordination of land use planning with water planning and management. State-supported investigations, and R&D of promising new technologies. Planners make more informed (less risky) decisions. Fewer gaps in data & analytical tools; better access to information.

19 19 Water Management Objectives Integrate & optimize management strategies Provide water supply benefits Increase drought resiliency Improve water quality Increase operational flexibility & efficiency Improve flood control Increase energy generation or reduce use Increase recreation opportunities Enhance instream, riparian or terrestrial ecosystems Reduce groundwater overdraft Reduce pollution Reduce runoff, drainage or tailwater Reduce uncertainty & risk

20 20 Key Themes, Findings & Recd State leadership & oversight for statewide assessments, protecting public assets; doing what regions cant do by and for themselves State promote & assist regionally-based, integrated, multi-resource planning State fill data/tool gaps & support R&D Regions diversify water portfolios choosing from 25 resource management strategies Locals improve coordination of land use planning with water planning/management

21 21 3.5 to 6 MAF Additional Demands for 2030 Current Trends Scenario To maintain QOL for 17 million more Californians –Additional 2 - 3 million acre-feet To recover groundwater overdraft –Additional 1 - 2 million acre-feet To protect & restore degraded ecosystems –Additional 0.5 – 1 million acre-feet To sustain econ growth & agricultural industry –About the same as now

24 24 Part 2 Developing a New Analytical Framework for the CWP Background and Context Anatomy of Models Proposed CWP Framework Proposed Conceptual Model Principles for framework Short Term Approach and Beyond Discussion and Possible Roles for CWEMF

25 25 Last Year at Asilomar …

26 26 What has Happened Since? Advisory committee was not comfortable with proposed approach –Didnt fully support or understand some of the models and modeling –Disagreed with using a single vision of future conditions DWR lacked resources to address problems within schedule DWR decided to take a slower, fundamentally different approach rather than disregard feedback

27 27 Where We Are Now State has leadership role in evaluating statewide water management strategies Complexity of CWP has increased DWR has held numerous public workshops to develop a proposed analytical framework Proposal has not been presented to or approved by full Advisory Committee

28 28 Anatomy of Models (Developed by Ken Kirby) Conceptual model Theoretical model Numerical model Data Data management Software

29 29 Definitions Conceptual Model - A description or analogy used to help visualize something that cannot be directly observed Theoretical Model - A system of postulates, data, and inferences presented as a description of an entity or state of affairs

30 30 Definitions Numerical Model - An analytical tool that employs quantitative approximations to the solutions of mathematical problems

31 31 Proposed CWP Framework Identify Required Information Develop Conceptual Models Develop Theoretical Models Develop Short Term Approach Conduct Quantitative Analysis for Update 2008 2003 - 2004 2004 - 2006 2005 - 2007

32 32 Conceptual Model Water Management System Water Management System Climate Conditions Economic and Performance Indicators Economic and Performance Indicators Ag/Urban Demands Ag/Urban Demands Ecosystem Demands Ecosystem Demands Ecosystem Wants Ag/Urban Wants Ag/Urban Wants

33 33 Straw Proposal for Presenting Conceptual Models Agricultural Water Demands Urban Water Demands Required Input Desired Output Required Input Desired Output

34 34 Principles for Development and Application of Tools and Data Strategy Transparency Long-Term Viability Coverage Accountability and Quality Control

35 35 Short Term Approach Propose changes to existing tools and data Develop list of data needs Modify existing tools and data Inventory analytical tools using Anatomy of Models Compare theoretical models to existing tools, data and conceptual models

36 36 Quantitative Analysis for Water Plan Update 2008 Future scenarios Performance measures Interpret and describe results

37 37 Update 2008 and Beyond Improve existing tools using conceptual model Fill data gaps Develop Water Plan Information Exchange (Water PIE)

38 38 Discussion and Possible Roles for CWEMF Anatomy of Models and CWP proposed framework Detailed inventory of existing tools and data Proposed conceptual models, desired output, and required input Evaluating adequacy of tools
