OLD RIVER LOCK

Mariners are advised that once water elevations reach 60.5 feet on the Red River Landing gage, Old River Lock will be closed to navigation. The closure is necessary to install the flood protection plates on top of the lock gates and uninstall all electrical equipment from the recess for the lock gate machinery when the water elevations reach 60.5 feet on the Red River Landing gage.

The lock will reopen once the Mississippi River recedes below 60.5 feet on the Red River Landing gage.
The Red River Landing gage is located on the Right Descending Bank (RDB) of the Mississippi River at mile 302.4 Above Head of Passes (AHP).

The lockmaster, Morris Oubre, can be reached at (225) 492-3333 for up-to-date information. The point of contact for the New Orleans District is Russell Beauvais at (225)-492-2169.
