East Park Dam

East Park Dam is an agricultural irrigation dam and reservoir built by the United States Bureau of Reclamation, on Little Stony Creek, about 30 miles (48 km) southwest of Orland, California on the northern end of the California Central Valley.

Its main structure is a curved, thick-arch concrete gravity dam, 92 feet (28 m) high, with two sluice gates.

The control house is in the shape of a pagoda, and the spillway, about 2,000 feet (610 m) south of the dam on the western side of the reservoir, features an eccentric set of curved labyrinth-spillway fins.
