Owyhee Dam, << oh WY hee or oh WY ee, >> is one of the larger concrete arch gravity dams in the world. It lies on the Owyhee River in Oregon, about 11 miles (18 kilometers) southwest of Adrian, Oregon, near the Idaho state line. The dam is 417 feet (127 meters) high and 830 feet (253 meters) long. It forms a reservoir 52 miles (84 kilometers) long that stores water for irrigating about 16,000 acres (6,470 hectares) of land. The reservoir holds about 715,000 acre-feet (882 million cubic meters) of water. This dam was built by engineers of the United States Bureau of Reclamation. It was completed in 1932 at a cost of $6,671,000.
