Hetch Hetchy / O'Shaughnessy Dam
Reservoir / dam · operated by the Public Utilities Commission
Wikimedia Commons · Isaiah West Taber · Public domainThe archive documents trace the O'Shaughnessy Dam and Hetch Hetchy system. A 2005 history records that San Francisco approved a "$45 million bond to build Hetch Hetchy System" in 1910, that the dam was built 1919-1923, and that it was later "raised to store 360,360 acre feet." A 1975-76 annual report of the Hetch Hetchy Water and Power System notes the dam was raised "an additional 85.5 feet," the system cost "some $100 million," and water reached Crystal Springs Reservoir in 1934. The system is operated by the Public Utilities Commission, whose FY2025 budget line is about $1.8B; a city contract for "Auto Parts for Hetch Hetchy" with Pine Mountain Auto Inc has been paid $28,748.78.
