Today, we’re discussing Little Goose Lock and Dam on the Snake River. The project was enabled by the River and Harbor Act of 1945. Construction began in 1963 and operation began in 1970. It creates the reservoir Lake Bray, which “extends upstream about 37.2 miles and provides navigation to Lower Granite Lock and Dam.”¹

The lock is a “single-lift lock, 86 feet wide by 668 feet long, with a 100-foot vertical lift. More than 1.9 million tons of commodities passed through the Little Goose navigation lock during 2015.”¹
