Description
This 27-inch cement ledge/drop can be quite sticky at good flows. At 750-850, the center looks unlikely to escape, but running a sneak route tight to either shore, angling toward center on your boof, should put you in the clear.
The cement bottom is uniform here, so if you end up caught in the hydraulic, worst case, you exit your boat, stand up, grab your boat, walk to the semi-steep sloping concrete, empty your boat and relaunch!
