Tulloch Dam

Dams Construction 








Tulloch Dam is a hydroelectric dam on the Stanislaus River in central California. The dam is part of the Stanislaus River Tri-Dam project cooperatively owned by the Oakdale and South San Joaquin Irrigation Districts, and was completed in 1958. It serves mainly for irrigation purposes but also has a power station with a capacity of 18 megawatts. The dam is located just downstream of the New Melones Dam and upstream of the Goodwin Dam.

Tulloch Dam
The Donnells dam, Beardsley dam and Tulloch dam projects are located in Tuolumne County, California on the Middle Fork of the Stanislaus River. OID and SSJID co-developed the "Upper Works" (Donnells and Beardsley) and the "Lower Works" (Lake Tulloch) of the Tri-Dam Project Donnells Reservoir, Beardsley Reservoir, and Lake Tulloch were fully operational just two years after its making was agreed upon in 1955.


The Tri-Dam met the irrigation obligations and in the 1980s added small hydro-power plants to the dams to provide electricity. The hydro- power plants are now currently controlled by the Turlock Irrigation District. The Tri-Dam project is currently composed of the dams, tunnels, penstocks, powerhouses, communications systems, and offices. All in which are stationed on the Middle Fork of the Stanislaus River.

The Tri-Dam Project administrative offices are in Strawberry, California. There is a General Manager who manages the daily activities of the Tri-Dam Project and the Tri-Dam Power. The General Manager then provides information to the five members on the joint board of directors. The Tri-Dam Power Authority is separate from the Tri-Dam Project, but the General Manager is the chief executive officer for both of them. More details
