At Nelson's Island drop over the ledge and enjoy some surfing. There is a very nice surf wave that develops between 1000 and 2000 cfs. Be mindful of the local residents who like to swim here. The river left bank has some sharp concrete blocks under water so if you go end up out of your boat swim to the island. This is the confluence of Wise Creek and the Ocmulgee and is the take out of this section.
