Wikimedia Commons · MikeVdP · CC BY-SA 4.0Camp Mather is a family camp San Francisco owns in Tuolumne County, near the north entrance to Yosemite, and its records read as a long argument about who gets to use it. It began as an industrial site: a history of the Hetch Hetchy system notes that sawmill operations at Hog Ranch — the future Camp Mather — were terminated as the water project advanced. Recreation and Park Commission minutes then carry the ordinary business of running a camp. In 1967 the commission approved the season's dates and rates and awarded a $13,887 construction contract to Malott & Peterson-Grundy for reconstruction of the camp's tennis courts; in 1998 it approved the first fee increase since 1995, presented as covering maintenance and repairs. The department's annual report counts 26,600 visits in a season, alongside its city playgrounds and pools. The sharpest document is the 2002-2003 Civil Grand Jury report, released in June 2003 as "Sharing Camp Mather, San Francisco's Secret Jewel, With All San Franciscans", which recommended that the city improve publicity and accessibility and study the use of the camp's facilities and grounds. Vendors have been paid $2.59 million on contracts recorded against the camp.
