On July 17, 1932, with the Great Depression grinding across America, he sent Secretary of the Interior Ray Lyman Wilbur to deliver his message at the dedication of what was then the tallest dam of its type in the world. The structure rising from the remote canyon of the Owyhee River in Eastern Oregon represented something beyond concrete and steel - it was proof that ambitious engineering could still proceed even as breadlines lengthened in the cities. Within two years, the techniques pioneered here would be scaled up for the far more famous Hoover Dam on the Colorado River. But first, there was this: a 417-foot wall of concrete holding back the waters of a river named for three Hawaiian fur trappers who had vanished in this country more than a century before.

Banks, the engineer who designed it, was perfecting methods that would reshape the American West. His arch-gravity design - a concrete structure that curves upstream to push against canyon walls while using its ...

The record high reached 112 degrees Fahrenheit in July 2002; the record low plunged to -22 degrees in January 1962. Annual precipitation averages less than 10 inches. Without irrigation, this is sagebrush country, home to jackrabbits and pronghor...

For roughly two years, Owyhee Dam held a distinction: tallest dam of its type in the world. The title passed in 1934 when France completed the Lac du Chambon dam at 448 feet, surpassing Owyhee's height. But the engineering legacy proved more durable than any record. The technique...

On September 23, 2010, it was added to the National Register of Historic Places as part of the Owyhee Dam Historic District. Haystack Rock Road still crosses the crest, just as it did when the dam was new....
