Los Vaqueros Reservoir : ウィキペディア英語版 | Los Vaqueros Reservoir
The Los Vaqueros Reservoir was completed by the Contra Costa Water District (CCWD) in 1998 to improve the quality of drinking water for its 550,000 customers in Central and Eastern Contra Costa County in Northern California. The name ''vaquero'' is Spanish and means "cowboy" in English. The reservoir is accessible via Vasco Road from Brentwood, California and Livermore, California. An expansion project begun in 2010 raised the height of the dam to increase storage capacity from 100,000 acre-ft to 160,000 acre-ft of water. ==History== Incursions of saline water into the Sacramento-San Joaquin River Delta from the San Francisco Bay has been a concern since the 1870s. This concern was one of the reasons CCWD was formed in 1936. A drought in 1977, caused salinity levels to exceed public health standards. It forced CCWD to ration deliveries of fresh water to its customers.〔(Los Vaqueros Project History ).〕
