The Lake Siskiyou Power Project was constructed at the foot of the existing Box Canyon Dam on the Sacramento River in Northern California. Major project features included the construction of a power plant with twin turbine-generator units at the rated capacity of 5 MW, underwater installation of a multiple-port intake structure, placement of an inclined tramway, rock scaling of narrow canyon walls and a water diversion scheme during construction. The most interesting and challenging feature of the Project is the arrangement of tucking the power plant under the extended existing spillway slab. This arrangement made the project development feasible and resulted in minimal environmental impacts. The Project was successfully implemented with power generation beginning May, 1986, a realization of nine-year public and private joint development efforts.
