The Bonneville Lock and Dam is a national historic landmark as of 1987. It was the first federal lock and dam, on the Columbia and Snake rivers in Oregon, built and operated by the U.S. Army Corps of Engineers. It’s amazing how many megawatts have been generated there and distributed all over the west coast, even to Los Angeles. The parking lot has a great view of the mountains and the dam itself, and the visitor center was very educational and informative. We saw the life cycle of salmon swimming upstream and the generators inside of the power plant. If you donate cash, you can also get some stickers.
