Priest elevation at noon Wednesday was 504.58 and appears to have crested.
The current combination of releases through spillway gates and hydropower
generation is being used to lower the lake level.
-
The spillway
releases will be increased when it is determined that doing so will not
adversely affect downstream areas. Cheatham Dam on the Cumberland River, Ashland City, Tenn. - Cheatham Dam is in free flow with water flowing over the top of the dam’s spillway. The dam was designed to operate in this manner in high water situations. - Cheatham Lake reached a record level of 404.15, and the lock and resource manager’s facilities have flooded in the process. - Cheatham will remain in free flow until river flows reach a point that the gates can be placed back in the water and water control capabilities are regained. This will be followed some time later by placing the hydropower units back in service.

Cheatham Lake elevation at noon Wednesday was 401.1. The
lake is forecasted to return within normal operation levels by Sunday. Barkley Dam on the Cumberland River in Grand Rivers, Ky. - The Great Lakes and Ohio River Division (LRD) Water Management Office has an ongoing flood control operation for the Ohio River.

We are working closely with LRD and Tennessee Valley Authority (TVA) staff to develop operation plans. - Reductions in releases have been implemented at Barkley. The flow of 228,000 cubic feet per second will be maintained throughout Wednesday, then cuts will be made to prevent flooding on the Ohio River. - Lake Barkley elevation at noon Wednesday was 366.7.
