Here is a video of Kayaking on the Slippery Rock at too high a level.
https://youtu.be/OBWMIHlhObI I lived in New Castle and did this section all the time. This level is asking to die. Lots of undercut rocks,fallen trees and no eddies at this level. I would never do this in a white water Kayak over 2.5 on the McConnell mill gauge. Look at the level they are doing it. They are good but rolling the dice.
