This paper will explore how water, energy, food, and climate change are interconnected with ecosystems, and why we need to understand these connections and identify information gaps and related challenges and opportunities for ecosystem services in multiple sectors.
The Office of the State Climatologist of California has released a report on key indicators for hydrology and climate in California. This report will be updated annually with the newest available data to track important trends, and provide graphical visualization of data trends that are of interest.
Strategies for Achieving Water Sustainability was written by the Water Leaders Class of 2016 to address the various challenges and water issues in California. The report explores 24 strategies for achieving sustainability in the areas of water supply, demand-side management, laws and governance, funding, public education, and data.
The California Department of Water Resources (DWR) collaborated with the California Ocean Science Trust (OST) and the Scripps Institution of Oceanography (SIO) to equip local communities with tools and information to adapt to coastal flood hazards caused by climate change. A grant from the National Oceanic and Atmospheric Administration’s Coastal and Ocean Climate Applications program provided funding for the project, which was also supplemented with additional funds from DWR.
Anthropogenic climate change amounts to a rapidly approaching, “new” stressor in the Sacramento–San Joaquin Delta system. In response to California’s extreme natural hydroclimatic variability, complex water-management systems have been developed, even as the Delta’s natural ecosystems have been largely devastated. Co-authored by DWR Jaimie Anderson and Mike Anderson with others.
In this conceptual framework, climate change drivers of changing temperature, snowpack, and precipitation are interlinked with life cycles in water, energy, food, and related key elements in ecosystem processes. Dr. Qinqin Liu, DWR Climate Change Program; Ecological Processes, December 2016 issue
Plans show how state government is acting to convert the recommendations from the 2014 Safeguarding California: Reducing Climate Risk report. DWR was the lead author for the Water Sector Plan.
This Technical Information Record represents the preliminary findings from 2012-2015 by DWR’s expert external advisory committee, the Climate Change Technical Advisory Group, on global climate model selection appropriate for California water resources, planning for extreme conditions, downscaling, and recommendations for future work.
DWR releases science and data critical for climate change adaptation and mitigation for water management in California. The booklet summarizes the latest indicators, implications and strategies with regard to a changing climate and the water-energy nexus.
This study evaluates the future of water rights reliability in the Sacramento-Feather-American river watersheds. Projections of future water rights curtailments show that water rights holders are likely to be curtailed much more frequently and for significantly longer durations as we move through the 21st century. Andrew Schwarz, Journal of San Francisco Estuary and Watershed Science.
This report, commissioned by DWR to help gauge the usefulness of the 2011 Climate Change Handbook for Regional Water Planning (DWR, USBR, USACE), Dr. Holly Alpert catalogues the experiences of IRWM practitioners who used the Handbook to conduct their IRWM Plan climate change analyses. Recommendations are provided for future DWR work to support regional implementation of climate change adaptation efforts.
This exploratory study develops and describes a methodology that uses readily available research data sets to produce gridded estimates of historical rainfall as a fraction of total precipitation for areas comprising the major water-supply watersheds of California. Written by Aaron Cuthbertson (DWR), Elissa Lynn (DWR), Mike Anderson (DWR, California State Climatologist) and Kelly Redmond(Western Regional Climate Center).
This study analyzes the origins and functioning of the Integrated Regional Water Management and Regional Flood Management Planning processes, and the degree of coordination between them to address flood risks in the Central Valley. It examines how these two processes are working to generate multi-benefit strategies and account for climate change, and discusses opportunities for future coordination. This report was written by Esther Conrad, PhD candidate in Environmental Science, Policy and Management at the University of California at Berkeley.
New Hydroclimate Reconstructions have been released, using updated tree-ring chronologies for these California river basins; Klamath, San Joaquin and Sacramento. The report, prepared by the University of Arizona, allows assessment of hydrologic variability over centuries to millennia, gives historic context for assessing recent droughts, and can be used in climate change research.
This paper presents four commentaries on water management and adaptation to climate change by four practitioners who work on these issues, incuding DWR's Katherine Spanos.
Urban Water Management Plans (UWMPs) are an important element of California’s efforts to assure reliable water supplies. This study assesses how water suppliers have considered the impacts of climate change and greenhouse gas emissions in their 2010 plans, and provides recommendations for how DWR could improve its climate change guidance for 2015 UWMPs. This report was written by Esther Conrad, PhD candidate in the Department of Environmental Science, Policy and Management at University of California Berkeley.
Discusses the current state of DWR's Volunteer Climate Cooperator Network, and makes suggestions for the future of the program.

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.
|"Atmospheric Rivers" (2015)
Atmospheric Rivers are vital for water supply in California. The frequency and intensity of these powerful storm systems also play a role in both flood and drought risk in the State. Elissa Lynn of the CA-DWR Climate Change Program meets CalWater researchers as they head to the Pacific to measure A/R’s.
|"A Climate of Change" (2009)
Host Elissa Lynn talks to an array of climate and water resource experts about the impacts of climate change already being felt in California and the adaptation strategies that will be needed to manage the state's water resources in the future. (Produced by DWR, in conjunction with the Water Education Foundation).
|"Climate Change: Water Wise" (2007)
Senior Meteorologist, Elissa Lynn, and DWR Executive Manager for climate change, John Andrew, explain climate change projections and their possible impacts to water management in California. This video uses the National Oceanic and Atmospheric Administration's (NOAA) Science on the Sphere technology to display current and future global warming.
|Science On a Sphere is the centerpiece of this fun, educational, interactive exhibit on Climate Change.
It is a 6-foot video display globe showing 3-dimensional movies of hurricanes, tsunamis, global warming,
atmospheric rivers with flood potential, the oceans and atmosphere of Earth, as well as the Moon, Sun,
and planets. The Department of Water Resources and the National Weather Service, Sacramento office/ NOAA
are partners in this display. Additional hands-on exhibits include projections of climate change impacts
on California and how the State is responding, a drought/conservation display, a climate wheel and hopscotch
for kids, a Flood Plain model, and the ever-popular water burger.
