Donnells Dam (National ID # CA00264) is a concrete arch dam located on the Middle Fork of the Stanislaus River in Tuolumne County, California.[5] The water impounded by the 291-foot (89 m) high dam forms Donnell Lake in Stanislaus National Forest.[5] The dam and reservoir are co-owned by the Oakdale Irrigation District and South San Joaquin Irrigation District, and the dam is one of three in the Tri-Dam Project.[6] The other two dams in the project are Beardsley Dam and Tulloch Dam.
The dam has a length of 750 feet (230 m) at its crest and a storage capacity of 56,893 acre-feet (70,176,000 m3).[5][6] Donnells Reservoir, along with the two other dams of that make up the Tri-Dam Project, currently provide water for the irrigation of about 117,500 acres (47,600 ha) of farmland in Stanislaus and San Joaquin counties.[6] The reservoir also generates hydroelectric power and supplies water to urban areas.[7]
