Mammoth Cave National Park Public Information Officer Vickie Carson has reported that the Green River Ferry is closed today, Wednesday, April 15, 2015. The closure is due to high water. The river currently measures 24 feet at the ferry landing and is rising.
With much more rain in the forecast and a flood warning already issued for much of the Green River area, it is unknown when the ferry will reopen.
