Agenda Now Posted for Special June 9 Workshop in Southern California on Precipitation Forecasting & Drought Management
One-Day Event in Irvine will Help Water Managers 'Get Ahead of the Storms' to Better Manage Drought

Lake Oroville shows the effects of drought in July 2021, with little water in an arm of the lake.California’s vast network of surface water reservoirs is designed to hold carryover storage from year to year to ensure water is available for urban, agricultural and environmental purposes during dry months and years.

But climate change has begun to affect our reliance on historical weather patterns to predict California’s water supply, making it even more difficult for water managers to manage drought conditions and placing a greater emphasis on better precipitation forecasting at longer lead times.

Learn about efforts being made to ‘get ahead of the storms’ through new science, models and technology at our special one-day workshop June 9 in Irvine, Making Progress on Drought Management: Improvements in Seasonal Precipitation Forecasting. The event is sponsored by the California Department of Water Resources in partnership with the Water Education Foundation.

Wednesday Top of the Scroll: California bans watering of ‘non functional’ lawns around businesses as drought persists

Californians can expect to see more yellow grass around hospitals, hotels, office parks and industrial centers after water regulators voted Tuesday to ban watering of “nonfunctional” turf in commercial areas. The State Water Resources Control Board also moved to order all the state’s major urban water providers to step up their conservation efforts. The moves are the strongest regulatory actions state officials have taken in the third year of the latest drought.

California drought: Water wasters could face fines of up to $10,000 in Santa Clara County under new rules

Residents in Santa Clara County could face fines of up to $500 — and in extreme cases, $10,000 — for wasting water, under new drought rules approved Tuesday afternoon that are among the toughest of any urban area in California. … The new rules take effect June 1, but depend largely on citizen complaints and very few “water cops” to investigate them. Under the rules, residents who see water being wasted can notify the district of the address and date of incident by calling 408-630-2000, or emailing WaterWise@valleywater.org, or reporting online….

La Niña lives! — and that’s bad news

For two winters in a row, La Niña has steered desperately needed rain and snow storms away from the U.S. Southwest, exacerbating a decades-long drought that has shriveled reservoirs and spurred horrific wildfires. Now, hopes that the climate pattern would relent and allow moisture to rebound next winter have suffered a serious blow. La Niña — Spanish for “the girl” — persisted through April, and there’s a 61 percent chance she’ll stick around for a third winter, according to the latest monthly update from the National Oceanic and Atmospheric Administration.

California Tribal communities ask the State Water Resources Board to protect the Delta

As drought conditions continue, people who rely on the Sacramento-San Joaquin Delta are demanding California make sure their communities are protected. Early Tuesday, a group gathered in front of the California State Water Resources Control Board building to demand the state enforce the Bay-Delta plan. It’s been a long fight and the group said enough is enough. For many of the tribes, the Delta is an important lifeline.

Salton Sea

As part of the historic Colorado River Delta, the Salton Sea regularly filled and dried for thousands of years due to its elevation of 237 feet below sea level.

The most recent version of the Salton Sea was formed in 1905 when the Colorado River broke through a series of dikes and flooded the seabed for two years, creating California’s largest inland body of water. The Salton Sea, which is saltier than the Pacific Ocean, includes 130 miles of shoreline and is larger than Lake Tahoe

Drought

Drought—an extended period of limited or no precipitation—is a fact of life in California and the West, with water resources following boom-and-bust patterns. During California’s 2012–2016 drought, much of the state experienced severe drought conditions: significantly less precipitation and snowpack, reduced streamflow and higher temperatures. Those same conditions reappeared early in 2021 prompting Gov. Gavin Newsom in May to declare drought emergencies in watersheds across 41 counties in California.
