Bonneville Dam
The 928th tallest dam in the world
Bonneville Lock and Dam consists of several run-of-the-river dam structures that together complete a span of the Columbia River between the U.S. states of Oregon and Washington at River Mile 146.1. The dam is located 40 miles (64 km) east of Portland, Oregon, in the Columbia River Gorge. The primary functions of Bonneville Lock and Dam are electrical power generation and river navigation. The dam was built and is managed by the United States Army Corps of Engineers. At the time of its construction in the 1930s it was the largest water impoundment project of its type in the nation, able to withstand flooding on an unprecedented scale. Electrical power generated at Bonneville is distributed by the Bonneville Power Administration. Bonneville Dam was named after an adjacent railway station, which in turn was named for United States Army Captain Benjamin Bonneville, an early explorer and fur trader, who never came close to the site. The Bonneville Dam Historic District was designated a National Historic Landmark District in 1987.
