"Completed in 1925, Lower Baker Dam is a concrete gravity-arch dam at the south end of Lake Shannon. The dam is 285 feet [87m] high and measures 550 feet [168m] across at the crest. Twenty-three spill gates run across the top of the dam, with non-overflow sections to the east and west of the spillway section."
