![]() ![]() With these issues in mind, officials are seeking a permanent solution to the water export/endangered species conflict through the Bay Delta Conservation Plan, a collaborative effort by state, federal and local agencies and environmental organizations. Protections for declining populations of Chinook salmon and Central Valley steelhead also limit water exports. The tiny native fish is federally recognized as an endangered species and an indicator of the Delta’s overall environmental health. In 2007, the state shut down exports after more than 200 delt smelt were killed at the south Delta pumps. In addition, scientists say there is a major threat of Delta levee failure from an earthquake or flooding, which could severely impair Project operations and California’s water supply. Government protections of some fish species limit pumping at certain times of the year. The State Water Project and federal Central Valley Project export water from the south Delta. Others argue that operating at full capacity will further harm the Sacramento-San Joaquin River Delta ecosystem.

The Project originally was conceived as a much larger water delivery system, but only its first phase was completed. Even then, the Project faced formidable engineering obstacles, including the highest water lift in the world over the Tehachapi Mountains south of Bakersfield. Proposals similar to the Project date back to the 1880s, but the political and financial support for construction was not secured until the late 1950s. Take an aerial tour of the State Water Project. Providing recreation at many of its reservoirsĬreating the Project took many decades and considerable political and engineering effort.Helping manage floods in the Sacramento Valley.Boosting California’s agricultural industry to be among the global leaders.Supplying Silicon Valley with reliable, high-quality water vital to high-tech manufacturing.Fueling Southern California’s population and economic growth.Overviewīuilt and operated by the California Department of Water Resources, the State Water Project is the largest state-financed water project ever built. Today, an average of 34 percent of Project water supplies agriculture, mostly in the San Joaquin Valley, and 66 percent goes to homes and businesses, mainly in Southern California but also in the Bay Area. Its key feature is the 444-mile-long California Aqueduct seen along Interstate 5. The Project diverts water from the Feather River to the Central Valley, South Bay Area and Southern California. Without it, California would never have developed into the economic powerhouse it is. The State Water Project is an aquatic lifeline for California because of its vital role in bringing water to cities and farms. Western States Water Agencies and Districts.State and Federal Legislative Committees.California Content Standard Correlations.The City works with other CCWA Member Agencies to optimize the benefit of its State Water Project allocation, including looking for opportunities to bank or store State water in wet years and secure a more reliable source of State water in dry years. During drought-related water shortages, the City may also make supplemental water purchases through the State Water Project to augment depleted surface water supplies. Aside from this, water is ordered annually on an as-needed basis to replace local surface supplies lost to drought or as a result of other shortages. The City typically takes State Water deliveries of approximately 600 to 700 AF pursuant to its obligation under the Exchange Agreement with the Santa Ynez River Water Conservation District, Improvement District No. The amount of water that can be delivered throughout California from the State Water Project varies year to year based on rainfall and riparian flow rates. Average "normal year" deliveries (which typically occur under average rainfall conditions) to the City are estimated at 1,800 acre feet per year under the 2020 Enhanced Urban Water Management Plan, with annual deliveries projected to range from 165 AF per year to 2,100 AF per year. The City's entitlement is 3,300 acre feet per year, subject to availability. When needed, South Coast participants receive State Water through the Tecolote Tunnel, intermingled with Cachuma water, but accounted for separately. State Water is delivered via the 102 mile Coastal Branch of the State Aqueduct and the 42 mile Santa Ynez Extension that was completed in July 1997 and ends at Lake Cachuma. The City is a participant in the State Water Project as a Member Agency of the Central Coast Water Authority (CCWA), one of 29 State Water Project contractors. ![]()
