Navigation Notice 21-09: Cheatham Lock at Cumberland River mile 148.6 in Ashland City, Tennessee, is closing, with some restricted openings, during five phases from April 12 to June 10, 2021 to allow for maintenance workers to cut slots for stoplogs. Closures start at 6 a.m. each day as indicated in the table below.
During the time of restricted openings, there will be a dewatering box protruding into the chamber approximately 9 feet. To safely pass cargo through the chamber during the restricted openings, the following rules have to be followed: total dimensions of the boat and tow shall be no larger than 70-feet wide and 795-feet long. 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.
