Additionally, the U.S. Army Corps of Engineers is watching this weekend's forecast and how this will effect the dam systems, lakes and rivers.
Here are the areas the Army Corps is watching.
- Due to the high volume of expected rainfall, navigation at Cheatham Lock may be impacted by this weekend, with potential short-term restrictions or closures lasting approximately two to three days.
- The USACE storage reservoirs of J. Percy Priest, Center Hill, Dale Hollow, and Wolf Creek currently have empty flood storage zones and may see rapid rises in lake levels as they hold back flood waters. These waters will be slowly released after the rain ends to prepare them for future events.
- Cordell Hull, Old Hickory, and Cheatham Dams do not have built-in flood storage and must release the water that runs into them, this may be done using their spillway gates or hydropower turbines, depending on the dam and how much water they must release.
