See the TVA Appalachia Dam release schedule. Flows can change hourly.
Continue down the left channel around Big Island. The channel widens and then begins to both drop over another series of ledges, as the channel constricts. The fast current and turbulent water form Devil's Shoals. As you work down the ledges, there are eddies that can be caught on the right. As you work down the rapid, a ledge appears on river left, work down the center of the channel for this last section.
