About

Cossatot Falls drops through four miles of Class IV-V whitewater that ranks among Arkansas's most technical paddling, demanding expert skills and flows between 300-2,000 CFS on gauge 07340300. The river averages 520 CFS through Polk County, but the falls section becomes a different animal entirely when spring rains push water over the ledges and pour-overs that define this stretch. Above the falls, the upper Cossatot offers Class II-III warm-up water, while the Sandbar to Ed Banks section covers five miles of sustained Class III-IV drops. Cossatot River State Park-Natural Area manages both access and the surrounding corridor, with the Arkansas Natural Heritage Commission overseeing conservation of the watershed's rare plant communities. The 15-mile run concentrates most of its gradient and technical features in that infamous falls section — paddlers who can handle the upper miles shouldn't assume they're ready for what lies downstream.
