Rock Creek (Cumberland trib) - C) White Oak Junction to Big S. Fork of Cumberland R. (0.6-4 miles) (KY)
Approximate - nearest available gauge. Use as general reference only.
Big ledge hole on the left with some rocky lines on the right that open up with more water. The left line here is a legit class IV when the BSF gauge is maxed out, due to the very powerful hydraulic.
