The Owyhee Dam is a dam in the eastern part of the US state Oregon . The concrete arch weight wall was completed in 1932. A hydropower plant generates electricity and the water is used for irrigation in several districts in Oregon and neighboring Idaho . When the dam was completed, until the Chambon dam was built in France in 1934, it was the highest on earth at 137 meters. She overtook the 119 meter high Diablo dam . The Owyhee River is dammed to the Owyhee Reservoir with a capacity of 1480 million m³. A road leads over the dam.
The catchment area stretches across eastern Oregon and western Idaho.
The dam served as a model for the larger Hoover Dam on Colorado, including the concrete cooling during construction. The dam cost $ 6 million and the entire irrigation project cost $ 18 million. The Owyhee Dam was designed by Frank A. Banks, who also built other dams such as the Grand Coulee Dam on the Columbia River .
The dam was rebuilt from 1990 to 1993. The possibility of generating electricity was created as early as the 1980s.
Built without a fish ladder , the dam prevents the salmon from migrating up to Nevada .
The Owyhee Dam Historic District is in the list of National Register of Historic Places entered.
