An ambitious plan to build the largest new reservoir in California in 40 years to supply water to homes and businesses from the Bay Area to Los Angeles, along with Central Valley farmers, is being scaled back considerably amid questions about its $5 billion price tag and how much water it can deliver.

Sites Reservoir is proposed for construction in remote ranch lands in Colusa County, about 70 miles north of Sacramento. The reservoir, originally designed to be four times as big as Hetch Hetchy Reservoir in Yosemite National Park and nearly as big as San Luis Reservoir between Gilroy and Los Banos, received more money than any other project two years ago from a water bond passed by state voters during California’s historic drought.
