lock gates
Water level controllers
Lock gates are the hinged or sliding doors at each end of a canal lock, designed to hold back water and create a watertight chamber.
By opening and closing the gates, boats can be raised or lowered between water levels of different elevations: The lock gates slowly swung open as the water equalized.
Most locks have two sets of gates—one upstream, one downstream.
