The Kentucky Lock at Tennessee River Mile 22.4 in Grand Rivers is closed until further notice after a barge sank Saturday night in the lock chamber.
No one was injured and officials say Barkley Canal connects the Tennessee River with the Cumberland River and that traffic can be rerouted through Barkley Lock.
Kentucky Lock is the lower gateway to over 700 miles of navigable waters in the Tennessee River Basin and around 57 million tons of cargo valued at over $10 billion pass through the system each year.
