Structure to be closed from June 17 to July 11 for navigation gate dewatering

NEW ORLEANS – The U.S. Army Corps of Engineers will close the Calcasieu Saltwater Barrier to navigation at 7 a.m. on June 17 to conduct maintenance and repair activities, including dewatering of the navigation gates.   The closure of the structure is scheduled to last until July 11. During the closure, recreational boat traffic will be prohibited from passing through the structure. 

The Calcasieu River Saltwater Barrier (CRSWB) is located on a floodway by-pass channel that cuts off a meander channel of the Calcasieu River in Westlake, Louisiana, across the Calcasieu River from Lake Charles, Louisiana.  This structure is designed to reduce saltwater intrusion that threatens sensitive wetlands and agricultural irrigation processes located upstream of the barrier.  Constructed in 1968, the structure is operated year round from 6:00 a.m. to 10:00 pm Sunday through Thursday, with extended hours of 6:00 a.m. to midnight Friday and Saturday.

Updates regarding this closure will be posted to the following.
