Caution: river left is extremely hazardous. This feature forms at high flows over the remnants of an old dam, creating a powerful hydraulic that can trap and hold surfers down. River right is considered safe, as the old dam structure is no longer present there. The wave itself forms in the center of the river and, under the right conditions, produces a large, clean, and well-shaped rideable wave—powerful, beautiful, and highly sought after by experienced surfers.
