During the time of restricted openings, there will be a dewatering box protruding into the chamber approximately 9 feet.

Normal size barges passing through doublewide during the restricted opening will have 31-feet clearance. Chemical and fuel barges will only be allowed to pass through single wide during the restricted opening, and will have 47-feet clearance. A helper boat will be required to guide the tows past the restricted area going up and downstream. This schedule may change due to unforeseen circumstances, including weather delays, high water, unexpected mechanical issues, etc. The project engineer will communicate such changes as they arise.
