The Pedro Miguel locks being built, 1912: The Panama Canal locks at Pedro Miguel are almost finished here. At the left are the giant lock gates--some gates on the canal locks are 82 feet high. The tunnel at the right in the bottom of the wall is a “culvert.” Water flows into and out of the culvert to raise or lower the level of water in the lock. Up to 26 million gallons of water are used every time ships are raised or lowered. Scientific American Supplement, November 23, 1912
