The upper limit is a rough guess, based on historical data for this gauge. If you have better beta, please add a comment.
Left of the island is the prefered route as it has more water. When the ledge in the center tooth is getting hit but not covered with water there's a Attainment service to a fun surfing hole/wave just above the huge rock on river left at the bottom.
Right of the island is undercutting and often has awkward wood.
