According to UCLA climate scientist Alex Hall and co-author Neil Berg, the Sierra Nevada snowpack, which provides 60 percent of the state’s water, has been severely diminished by human-induced climate change. If emissions levels aren’t decreased, the snowpack could largely disappear during droughts. The consequences of the Read more

UCLA Facilities Management’s water efficiency project saves 28 million gallons annually. In the next few years, the total is expected to grow to 48 million gallons.

UCLA’s extensive water-saving program was recognized as Water Efficiency Project of the Year by the Los Angeles Better Buildings Challenge at the third annual Innovation Awards ceremony on Tuesday, February 28. The water reclamation program at UCLA conserves 28 million gallons of water every year and uses this water to cool the campus cogeneration plant that provides efficient power to the university. This marks the second time this year that Read more

California needs is a water infrastructure vulnerability assessment that includes dams, aqueducts and coastal aquifers. This assessment must be used to develop a priority list for retrofits and construction.

California has seen an unusual winter with increased storm activity in both its Northern and Southern regions. This has raised an alarm for the state’s dated-infrastructure as is the case with the unfolding situation of Oroville Dam. In an Op-Ed for the Sacramento Bee, Alex Hall, UCLA atmospheric and oceanic professor, and Mark Gold, associate vice chancellor for environment and Read more

Following 5 years of severe drought, California’s water infrastructure is struggling to adapt to unusually heavy precipitation this year. According to UCLA atmospheric researcher Daniel Swain, California’s climate has always been characterized by the presence or absence of atmospheric rivers, which result in alternating drought and flood conditions in the state. Even though this has historically been the case, researchers warn that a warming climate will Read more

The California Department of Water Resources stopped the spillway flow on Thursday morning to allow engineers to evaluate the integrity of the structure after water had been released at 20,000 cubic feet per second (cfs) through the night. There is no imminent or expected treat to public safety or the integrity of Oroville Dam at the Butte County site. After conferring with State and federal dam safety entitles, DWR decided to increase the release volume to 35,000 cfs to help operators absorb the inflow of the storm waters expected today and Friday. More erosion is also expected.

Mark Gold, UCLA Associate Vice Chancellor for Environment and Sustainability, sat down with KPCC’s Take Two to discuss the Oroville Dam and the role of climate change in the future of infrastructure. Gold leads the university’s Sustainable LA Grand Challenge, which aims to achieve 100% renewable energy and 100% locally sourced water, while enhancing ecosystem  Read more
