The U.S. Army Corps of Engineers has proposed removing a dam on the Green River near Mammoth Cave National Park.
The Daily News reports a study includes the recommendation, saying the action would improve aquatic life and recreational activities. Alternative actions include modifying the lock and not disturbing the dam, installing a barricade and disposing of the property or doing nothing.
The river has been closed to navigational traffic for decades and the study says the dams on the river have continued to deteriorate. In addition to removing Green River Dam No. 6 near Mammoth Cave, the study recommends disposing of three other dams along the river as well as Barren River Lock and Dam No. 1.
The federal agency is accepting comments on the proposal through March 17.
