Our California Water Map, recently updated, is one of our most popular products. We also offer magazines, documentaries, posters, layperson guides and more. Our catalog offers a wide array of resources to help you understand the complex issues of water in California and the Southwest.
California’s groundwater is a great natural resource and has contributed to the state becoming the nation’s top agricultural producer and a leader in high-tech industries. Groundwater is an asset that is increasingly relied upon by municipalities, industry and agriculture and it will play an important role in the future sustainability of California’s overall water supply.
The whims of political fate decided in 2018 that state bond money would not be forthcoming to help repair the subsidence-damaged parts of Friant-Kern Canal, the 152-mile conduit that conveys water from the San Joaquin River to farms that fuel a multibillion-dollar agricultural economy along the east side of the fertile San Joaquin Valley.
Learn from top experts at our annual Water 101 Workshop about the history, hydrology and law behind California water as well as hot topics such as water flows, the Delta, disadvantaged communities and the Sustainable Groundwater Management Act. For the first time, the workshop offers an optional groundwater tour the next day.
The biggest storm of the year packed the punch forecasters called for, walloping the Sierra Nevada with several feet of snow, and wreaking havoc on local highways and roads. Earlier in the week, the National Weather Service Office in Reno issued a blizzard warning for the greater Tahoe area, a rare report since 2008. Regional ski resorts, which had seen scant snow until recent storms swept through earlier this month, reported several feet of fresh snow in the past few days.
Because of the potential of massive flooding, the Army Corps of Engineers is rushing to begin a $500-million repair project for Whittier Narrows Dam, classified as the highest priority of any of the 13 “high risk” dams in the country. Nearly three years ago, the Army Corps of Engineers elevated the risk of failure from “high urgency” to “very high urgency” after a re-inspection revealed a greater threat of erosion and breach that would cause massive downstream flooding to one million Southern California residents in the event of a severe storm event.
At least one state agency has indicated it will not issue necessary permits to allow federal officials and a Fresno-based water district to begin construction to raise the height of Shasta Dam. In addition to facing opposition from the state, the project could also face fresh hurdles from Congress, which this year came under control of Democrats. In a letter to the Fresno-based Westlands Water District, the State Water Resources Control Board says raising the height of Shasta Dam would violate state law.
A group of Lake Nacimiento residents is suing Monterey County for $120 million, claiming officials ignored the needs of recreational users by releasing more water from the reservoir than necessary. The lawsuit, filed in San Luis Obispo County Superior Court in Paso Robles, alleges the county agency has mismanaged the reservoir and “operated the lake in a manner that renders it almost unusable by property owners and visitors for recreation.”
Wetlands are among the most important ecosystems in the world. They produce high levels of oxygen, filter toxic chemicals out of water, reduce flooding and erosion, recharge groundwater and provide a diverse range of recreational opportunities from fishing and hunting to photography. They also serve as critical habitat for wildlife, including a large percentage of plants and animals on California’s endangered species list.
As part of the historic Colorado River Delta, the Salton Sea regularly filled and dried for thousands of years due to its elevation of 232 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.
