Calaveras Replacement Dam

Calaveras Replacement Dam

Dragados and Flatiron are working together on this $498 million project to restore the Calaveras Reservoir to its historic capacity, which provides approximately half of the Hetch Hetchy Regional Water System's local Bay Area water storage. This storage is crucial to providing adequate water supply in times of drought. The new dam will have a structural height of 220 ft., a crest length of 1,210 ft., and a width of 80 ft. at the crest and 1,180 ft. at the base. 7 million cubic yards of excavation is required to construct the new dam.
