From the eddy behind the second drop, pull out into the swift current which is moving right to left over a shallow cobble bottom.
The slide starts under the bridge where the water slams into the left shore and rebounds to the right. There is a large standing wave (4') to the right center of the slide and this is your landmark. To the left of the standing wave the water feeds into an ugly recirculating hole that is fed on three sides. If you line up on the wave you'll be launched and land on the run-out of the slide which is shallow and fast.
Keep the boat straight here because of the shallow angled holes in the run-out.
