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 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.

  • "Climate Change and Integrated Regional Water Management in California: A Preliminary Assessment of Regional Approaches," June, 2012
  • Written by Esther Conrad, Dept. of Environmental Science, Policy and Management, University of California, this report examines the initial steps that IRWM (Integrated Regional Water Management) regions are taking in response to new requirements to address climate change vulnerabilities and consider greenhouse gas emissions in IRWM plans in California. Specifically, this report seeks to assess the manner and degree to which the climate change requirements in the 2010 IRWM Guidelines are met in Round1 Proposition 84 Planning and Implementation grant proposals, and in recently approved IRWM plans, assess current IRWM regional approaches to analyzing and adapting climate change risks in light of the overall goal to promote an adaptive management approach, and provide recommendations on key steps for DWR IRWM regions to support the development of informative climate change analyses and mechanisms for adaptive management at regional and state levels.
  • 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.
  • CEQA Information for Grantees: Process, Greenhouse Gas Analysis, and Climate Change
  • Information about key CEQA questions related to grant funded projects is found here.
  • IRWM Planning Grant Climate Change FAQs
  • This document has quick answers to frequently asked questions about the Climate Change standard included in the 2010 IRWM Planning Grant Guidelines.
