Everything to the left of the large rock island.
Long class II rapid with many surf waves. Just to the left of the island there is a chute that bypasses the last part of the rapid. At low levels (<5000), the last part of the rapid diverges. The far left channel is somewhat technical, whereas the line that turns sharply to the right is easier.
Another common line is to go down the wide ledge towards river center. Around 4000 cfs, this ledge has a small, but surprisingly retentive hole.
