Local and Regional Resources

In an effort to support improved climate change analysis in local and regional water resource planning and management, DWR has developed several resources for use by local and regional planning and management authorities.

While DWR provides statewide management of water resources in California, local and regional authorities control many important aspects of water resource management. DWR has identified Integrated Regional Water Management (IRWM) as one of the key initiatives for improving water supply reliability. And DWR manages several grant programs to promote and improve local and regional water resource management. Incorporating climate change analysis and adaptation planning is an increasingly important aspect of local and regional water resource management. Climate change is a global phenomenon but the impacts of climate change will differ regionally and the strategies for addressing the impacts of climate change will vary by location. Local and regional water resource managers are encouraged to minimize greenhouse gas emissions from their activities and to assess the likely impacts of climate change on their resources and develop strategies for adapting to these changes.

The resources published here are by no means exhaustive; these resources represent products developed by DWR or in which DWR staff contributed to development.

Technical Resources

General Information Resources

  • IRWM Climate Change Document Clearinghouse
  • DWR staff developed this clearinghouse in June 2010 to assist IRWM planning organizations with incorporating climate change information into IRWM plans. While the reports highlighted in the clearinghouse may still be among the best climate change references, the clearinghouse has not been updated since its issue date and therefore may not contain the most up to date information.
  • DWR Land Use and Climate Change Activities Summary
  • A summary of DWR programs that have a water management/land-use/climate change nexus and may provide opportunities for coordination and collaboration with other agencies and efforts.
  • Climate Change Vulnerability Matrix
  • Drawn from the California Adaptation Strategy and several other sources, this matrix provides a summary of the likely impacts of climate change on the seven most important resource sectors.
  • Accounting for Climate Change (in CWP 2009)
  • DWR Chief Hydrologist (retired) Maury Roos provided this California Climate Change impacts paper as part of the California Water Plan, 2009. It includes specific trends and impacts to the water resources of the State.

Resources for DWR Grant Programs

  • Climate Change Handbook for Regional Water Management - November 2011
  • Jointly developed by Department of Water Resources (DWR), U.S. Environmental Protection Agency Region 9, U.S. Army Corps of Engineers, and Resources Legacy Fund this handbook will provide a framework for integrating climate change analysis into regional water management planning as well as several case studies highlighting successful analyses performed by large and small water management agencies throughout the western United States.
  • CEQA Greenhouse Gas Analysis Guidance for DWR Grantees
  • The California Environmental Quality Act (CEQA) now requires analysis of the climate change causing greenhouse gases emitted by projects. Projects funded through DWR grant programs must meet the requirements of these new guidelines so that DWR can reach findings on these impacts. Because this is a relatively new field of analysis, DWR, as the responsible agency on grant funded projects, has developed guidance for complying with the new CEQA guidelines.
  • Frequently Asked Questions: CEQA Process for DWR Grant Programs (Including GHG analysis for CEQA Purposes)
  • Quick answers to frequently asked questions about complying with the new CEQA Guideline Amendments for analyzing greenhouse gas emissions.
  • IRWM Planning Grant Climate Change FAQs
  • Quick answers to frequently asked questions about the Climate Change standard included in the 2010 IRWM Planning Grant Guidelines.
