California is immersed in a third year of drought, with January, February and March of 2022 experiencing the lowest precipitation on record. Weather whiplash of big storms followed by dry spells makes every drop of rain, every flake of snow, and every water molecule vital this year for families, farms, the environment and the economy.

On April 8, DWR published the Bulletin 120 and Water Supply Index (WSI) forecast update. The Bulletin 120 is a key tool for water managers across the state to understand how the melting Sierra Nevada snowpack will reach streams, rivers and eventually California reservoirs. The forecast also has important legal impacts for water rights holders acros ...
California is no stranger to devastating floods. With the most variable weather conditions in the country, the state receives between 40 and 60 percent of its precipitation from atmospheric rivers, a stream of water vapor created in the atmosphere by circulating air currents over the waters of the Pacific Ocean.
DWR received its fifth Climate Leadership Award for its work teaching educators about the effects of climate change.
DWR took another step in its ambitious efforts to reduce climate change impacts by replacing an old electricity-generating turbine with a new, energy efficient model at the Ronald B. Robie Thermalito Pumping-Generating Powerplant in Butte County that will help the Department achieve its goal of using 100 percent zero-emission resources by 2045.
To adapt to intensifying extremes, federal, state, and local governments must be proactive in analyzing how climate change may impact California’s natural resources – as well as people and property. In a step to toward that goal, DWR released “Moving to Action”, a call for essential partnerships, planning, and collaboration with state, federal, and ...
DWR presented Climate Science Service Awards to four early-career scientists with the University of San Diego’s Scripps Institution of Oceanography at this year’s Winter Outlook Workshop.
“Pineapple Express” or “Atmospheric River” are terms you may hear often. But what do they mean, really? DWR Climate Change Program Section Chief, Elissa Lynn, gave a presentation on DWR’s Water Wednesdays live educational series where she discussed these storm systems, what they mean for California, and their impact on the state’s water reservoirs ...
California’s 2020 legislative session came to an end Sept. 30 with several new bills signed into law that will impact water operations and the Department of Water Resources.
California has the most variable weather conditions in the United States, often varying between extremes such as drought and flood. Our ability to forecast variable weather conditions well in advance is a driving factor in how water managers maximize the benefits and minimize the hazards of each storm.
