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.[1] The dam is located just downstream of the New Melones Dam and upstream of the Goodwin Dam.
