MAMMOTH CAVE, Ky. (AP) -- The ground under a dam supplying water for Mammoth Cave National Park and about 50,000 people in parts of four Kentucky counties is slowly eroding and in need of repair.
Green Valley Water District Manager David Paige said it's hard to tell how much water is leaking from the ground below the dam. The water comes from the Rio Verde Spring and supplies water to Hart County and parts of LaRue, Green and Taylor counties.
Paige told The Daily News the stone and masonry materials are holding up.
The district will get a $1.175 million low-interest loan from the Kentucky Infrastructure Authority to pay for the work.
The dam's depth is 20 feet and it is about 100 feet long. The area that needs repair is small.
