A short note on Bonneville Dam

The Bonneville Lock and Dam consist of numerous dam structures that together complete a span of the Columbia River between the US states of the Oregon and Washington at River Mile 146.1. The dam is situated 40 miles east of Portland, Oregon, in what is at present the Columbia River Gorge National Scenic Area. The most important functions of Bonneville Lock and the Dam are those of electrical power generation and the river navigation. The dam was built and is managed by the US Army Corps of Engineers. The Electrical power generated at Bonneville is spread by the Bonneville Power Administration. Bonneville Lock and the Dam are named for Army Capt. the Benjamin Bonneville, an early explorer credited with charting much of the Oregon Trail. The name is pronounced as BAH-nee-vill.
