Operated by the U.S. Army Corps of the Engineers, the San Francisco Bay/Delta Model is a hydraulic model of San Francisco Bay and the Delta and is housed in a converted World II-era warehouse in Sausalito in Marin County.
Stretching 320-feet by 400-feet wide, the Bay Model features a replica of the Bay Delta watershed from the Golden Gate to the Sacramento-San Joaquin Delta. Pumping systems move hundreds of gallons of water throughout the display and create 14-minute tidal ebb and flow.
Anne J. Schneider (1947-2010) is acknowledged as one of the first women to become well-known and well-respected in the field of California and Western water law. “Anne was an amazing person — an accomplished college athlete, mountain climber, skier, marathon runner, velodrome and long-distance cyclist; a devoted mother; a dedicated conservationist,” said Justice Ronald B. Robie in the Inaugural Anne J. Schneider Memorial Lecture in May 2012.
Located in the middle of California, the San Joaquin Valley is bracketed on both sides by mountain ranges. Long and flat, the valley’s hot, dry summers are followed by cool, foggy winters that make it one of the most productive agricultural regions in the world.
The valley stretches from across mid-California between coastal ranges in west and the Sierras on the east. The region includes large cities such as Fresno and Bakersfield, national parks such as Yosemite and Kings, millions of people, and fertile farmland.
Seawater intrusion can harm groundwater quality in a variety of places, both coastal and inland, throughout California.
Along the coast, seawater intrusion into aquifers is connected to overdrafting. Additionally, in the interior, groundwater pumping can draw up salty water from ancient seawater isolated in subsurface sediments.
In rural areas with widely dispersed houses, reliance upon a centralized sewer system is not practical compared to individual wastewater treatment methods. These on-site management facilities – or septic systems – are more commonplace given their simpler structure, efficiency and easy maintenance.
Shasta Dam forms the largest storage reservoir in the state, Shasta Lake, which can hold about 4.5 million acre-feet.
As the keystone of the federal Central Valley Project, Shasta stands among the world’s largest dams. Construction on the dam began in 1938 and was completed in 1945, with flood control as the highest priority.
Sinkholes are caused by erosion of rocks beneath soil’s surface. Groundwater dissolves soft rocks such as gypsum, salt and limestone, leaving gaps in the originally solid structure. This is exacerbated when water is acidic from contact with carbon dioxide or acid rain. Even humidity can play a major role in destabilizing water underground.
Sites Reservoir is a potential new offstream reservoir that would be located about 78 miles northwest of Sacramento at the eastern foothills of the California Coast Range. Proposed by the California Department of Water Resources (DWR), Sites Reservoir would harness winter flood flows from the Sacramento River, divert the water upstream and pump it into a deep, 14,000-acre reservoir formed in the Antelope Valley. The valley now is used for cattle grazing.
Robert A. Skinner (1895-1986) was the Metropolitan Water District of Southern California general manager from 1962-1967. An engineer, he was instrumental in negotiating the district’s contract with the California Department of Water Resources for delivery of water from Northern California. Both Lake Skinner and a treatment plant in southwestern Riverside County were named in his honor.
