From Limón Bay a ship is raised by Gatún Locks (a set of three) to an elevation 85 ft (25.9 m) above sea level, traverses Gatún Lake, then crosses the Continental Divide through Gaillard (formerly Culebra) Cut and is lowered by Pedro Miguel Lock to Miraflores Lake and then by the Miraflores Locks (a set of two) to sea level. The average tidal range on the Atlantic side is less than a foot (.3 m); that on the Pacific side is 12.6 ft (3.8 m).
