The U.S. Army Corps of Engineers Nashville District announces that releases from Barkley Dam on the Cumberland River in Grand Rivers, Ky., will be reduced to 6,000 cubic feet per second beginning 4 a.m. Thursday, Sept. 14 to support repairs to wicket gates at Dam 52 on the Ohio River in Brookport, Ill. The Louisville District reports that the dam is currently not operating as designed, which has caused river traffic on the Ohio River to be suspended. The Barkley lockmaster will cease lockage for commercial navigation once the tailwater drops below elevation 298.4. Lockage of recreational traffic will be at the lockmaster's discretion when the tailwater drops below elevation 298.4. Park rangers at Lake Barkley will monitor conditions and may close the right bank tailwater boat ramp below Barkley Dam to recreational vessels if conditions necessitate.
