The ongoing deterioration of a dam on the Green River in south central Kentucky is creating potential safety hazards. A hole in the foundation of the dam has lowered water levels and resulted in swift currents. The Corps of Engineers is advising boaters to avoid the upstream side of the dam.
The river runs 26 miles through Mammoth Cave National Park.
"The river is really dynamic on a good day, a normal day, so after this, we're waiting to see how it reacts to this new level, said Vickie Carson, public information officer at Mammoth Cave National Park.
Access to the Green River at Houchin Ferry is closed due to the sudden drop in water levels following the breach. Levels have dropped by as much as nine feet in some areas. The park will re-assess river access at Houchin Ferry in the coming months. The campground and picnic area will remain open.
Officials says while the collapse of the dam is possible, it would not be severe enough to cause any damage.
