Resources for Water Managers

Local and regional water authorities are important partners in the statewide response to climate change. DWR supports local and regional planning and management authorities in their climate change analysis and resource management planning by providing greenhouse gas analysis guidance, climate change guidance for regional water management and annual hydroclimate reports.

Recently, Considering Climate Change Impacts in Agricultural Water Management Planning was released for agricultural water suppliers that seek additional assistance on how to consider climate change in their agricultural water management plans. This guidance is not prescriptive, but describes common approaches to analyze and incorporate climate change in planning and management.

In partnership with the U.S. Environmental Protection Agency, Resources Legacy Fund, and The U.S. Army Corps of Engineers, we developed the Climate Change Handbook for Regional Water Planning , which provides a framework for considering climate change in water management planning. Key decision considerations, resources, tools, and decision options are presented that will guide resource managers and planners as they develop means of adapting their programs to a changing climate.

Integrated Regional Water Management (IRWM) is a key initiative for addressing climate change and improving water supply reliability. We manage several grant programs to promote and improve local and regional water resource management by incorporating climate change considerations in IRWM planning analyses. The Accessory Climate Change Guidance for Integrated Regional Water Management provides strategies for adapting to climate change, and considerations for incorporating climate change analysis into California Environmental Quality Act documents.

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. We encourage local and regional water resource managers to minimize greenhouse gas emissions, proactively assess likely impacts of climate change on their resources, and develop strategies for adapting to these changes.
