BROWNSVILLE - The U.S. Army Corps of Engineers has proposed removing a dam on the Green River near Mammoth Cave National Park.
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.
The study anticipates the dam removal would take about two years to complete.
The study also noted economic benefits.
"Presently, the canoe liveries on the Green River serve canoeists wanting primarily half-day trips," the Corps of Engineers' study said. "Removal of the dam is expected to increase demand for multi-day canoe trips, leading to increased rentals and revenues for local businesses."
