The Corps’ Mississippi Valley New Orleans (MVN) District’s Lock and Waterway Status 60-Day Forecast as issued today (June 11, 2018) is attached.

The status report updates conditions on the conditions on the Bayou Boeuf and Calcasieu Locks and the Schooner Bayou Control Structure:

The information for the Bayou Boeuf Lock as updated to include high water closures is reproduced below:

“Bayou Boeuf Lock is closed for navigation passage and will remain closed as long as the head differential remains above 1.5 feet due to high river conditions. Bayou Chene is currently available to use as an alternate route. There is currently no predicted date for resumption of open-pass operation.  The east end gates are installed and minor repairs of gate bay will continue until approximately the last week of June at which time the lock will reopen to navigation regardless of the head differential, which is keeping it closed at the time.”

The intermittent and scheduled closures at the Calcasieu Lock due to ongoing chamber guide wall work is reproduced below:

   “Calcasieu Lock will be closed to navigation intermittently Monday through Friday from 7 am until 5 pm each day. This schedule will continue until approximately 1 December 2019.”

The updated information for the Schooner Bayou Control Structure includes closures due to salinity control is reproduced below:

“Commencing at 6:00 p.m. today, 11 June 2018 and continuing until further notice, Schooner Bayou Control Structure is closed to navigation due to high salinity levels in the Mermentau Basin. All tows, light tugs, and cargo   carrying vessels will be diverted to Leland Bowman Lock.”
