California Water Challenges – Now and in the Future : 

California Water Challenges – Now and in the Future California Farm Water Coalition Jerry Johns Department of Water Resources October 2004

High Priority Water Issues: 

High Priority Water Issues Flood Management California Water Plan in 2004 Cal-Fed Bay Delta Program issues State Water Project Operations in a changing energy market Colorado River QSA Implementation Drought

Flood Management: 

Flood Management Central Valley Levees 1,600 Miles Joint State/COE Project Levees Paterno Court Decision 1986 break near Marysville – up to $.5 to 1 Billion Inherited Levee from 1911 – Old Ag. Levee Unknown Under seepage issues State held liable – Appeal Denied Budget increased after 1997 Floods but later reduced Solutions – White Paper – January 2005 Insurance beyond NFIP, Law changes, Infrastructure Investment, Flood Plain Management – Mapping and Land use, Maintenance and ESA protection issues, Improved timing with COE, others

Cal. Water Plan Overview: 

Cal. Water Plan Overview One of DWR’s Major Activities Required by law (Water Code) First Water Plan -Bulletin 3 (1957) Seven Updates (Bulletin 160) Updated every five years Last in 1998 Next in 2004 State’s Strategic Plan - For Water Resource Development

Population increase: 

Population increase 1990—30,000,000 people 2004—36,000,000 people Growth rate is about 600,000 people per year 2030 population is projected to be about 48,000,000 people An increase of 12,000,000 people

Managing for Change: 

Managing for Change Population Changes will require: More water – Likely – Different Futures More reliable water supplies More housing, roads, schools, etc. More facilities for treating and disposing of larger amounts of waste products Trends in hydrologic conditions – continue? Effects on snow pack and runoff patterns Possible less from our snow pact “reservoir” More intense runoff events

25 Resource Management Strategies: 

25 Resource Management Strategies Ag. Lands Stewardship Agricultural Use Efficiency Conj. Mgmt / GW Storage Conveyance Desalination Drinking Water Treatment & Distribution Economic Incentives (Loans, Grants & Water Pricing) Ecosystem Restoration Floodplain Management GW / Aquifer Remediation Matching WQ to Use Pollution Prevention Precipitation Enhancement Recharge Area Protection Recycled Municipal Water Surface Storage – CALFED Surface Storage – Region/Local System Reoperation Urban Land Use Management Urban Runoff Management Urban Water Use Efficiency Water-Dependent Recreation Water Transfers Watershed Management Other Strategies -Integrated Regional Management

Slide12: 

Framework for Future Action Fundamental Lessons Integrated Resource Planning & Management on regional basis Water Conservation is a foundational strategy statewide Water Storage for dry year reserve & strategy integration is needed in some regions

Sacramento-San Joaquin River Delta (Delta): 

Sacramento-San Joaquin River Delta (Delta)

CalFed Bay/Delta Program: 

CalFed Bay/Delta Program Storage 5 new sites studied – ½ money for studies Delta Water Quality Salinity, Dissolved Oxygen, TOC, THM precursors San Joaquin Inflow – Agricultural Drainage and Reservoir Flows Delta Improvement Package Delta Issues together – Conveyance improvement (6,680 to 8,500 cfs), coordination between CVP/SWP, fishery recovery, water quality, water levels, science Finance Plan – Beneficiary Pays/Public Funding Delta Levees

State Water Project (SWP): 

State Water Project (SWP) Provides at least part of the water supply to 2/3 of people in California Water to Lower San Joaquin Agriculture Deliveries - 3.3 MAF in 2003 2.7 MAF in 2004 FERC Re-licensing for Oroville Reservoir SWP is the largest energy consumer in State Energy Market changing - High Priority 2003 Bought $350 Million - Sold $100 Million Operate SWP like a business

Colorado River: 

Colorado River Quantification Settlement Agreement Significant but painful accomplishment Need formalized tracking system Salton Sea DWR doing CEQA for Salton Sea Restoration Drought California reservoirs low but not drastic Colorado System 54% Lake Mead Lowest since construction Effects on California Supplies from Colorado

Conclusion: 

Conclusion We will strive towards the goal of assuring that water resources are not an impediment to a vital economy, healthy environment, or quality of life.
