Calcasieu Lock is located on the Gulf Intracoastal Waterway just north of Calcasieu Lake in Louisiana. Calcasieu Lock has three main purposes: facilitate navigation, provide flood relief during high flow events, and prevent saltwater intrusion into the Mermentau River Basin. During high flow events, the primary purpose of Calcasieu Lock is draining for flood relief. The upstream and downstream gates open to pass as much water as possible. When in draining mode, currents through the lock increase in strength and can cause eastbound traffic with smaller horsepower towboats to be unable to push upstream through the lock. This causes delays for the eastbound traffic. The US Army Corps of Engineers, New Orleans District (MVN), proposed a diversion channel to alleviate the amount of flow the lock must pass during these high flow events. In 2019, the US Army Engineer Research and Development Center Ship/Tow Simulator was used to perform a navigation study for the proposed diversion channel at Calcasieu Lock to assist MVN in verifying the proposed design. The final assessment of the diversion channel was accomplished through analysis of ship simulations completed by experienced pilots, discussions, track plots, run sheets, and final pilot surveys.
