Cheatham Lock at Cumberland River mile 148.6 in Ashland City, Tennessee, announces that due to diving operations at Cheatham Dam between Sept. 21-24, 2020, there will be periods of little to no flow during daylight hours. The water level at the lower approach of Cheatham Lock will likely NOT drop below normal minimum pool conditions (354.0 ft.) but will approach that elevation. Mariners should take extra caution on the lower approach and not overload their barges or exceed channel depths on these dates. For more info, call the lock at 615-792-0627.
