Description
The river enters a large round pool with a very narrow exit. The rapid is a single steep drop. It is impossible to see the drop from a kayak, before committing to it. Always scout if unfamiliar with the drop or the flow as there tends to be strong recirculation at the base. Boats have to punch one side or the other of the hole, but the exact best line may vary with flow. Down the left side is usually best, but I am not sure if it is always best. Scouting from river left is easiest at higher flows but easier on the right at low flows. The right wall below the drop is very undercut at medium high flows and there is a strong eddy current going under it. If swimmers or equipment get pushed into this eddy, it can be awkward to reach them. Because of the undercut right wall, I think it is safest to always run the left side when possible. Scout to be sure.
The danger of the left side run is that the current often pushes boaters into an outcrop on the left. It takes some effort to push off and into the current. Kayakers can flip against this wall and get stuck there.
