Summary
| Description |
English: Waste weir (near Lock 20) on Chesapeake and Ohio Canal. Paddle valves are closed, boards are put in, so that the level (canal pound) be full. Boards determine height of water in the level (Canal Pound), since excess water spills over the top of the uppermost board. See image:Waste_Weir_Open_on_C_and_O_Canal.jpg for this same waste weir, open. |
