The Walters Dam failure refers to the catastrophic failure of the Walters Dam (also referred to as the Waterville Dam) in Haywood County, North Carolina on 27 September 2024, and the subsequent drastic flash flooding of the Pigeon River and settlements downstream of the dam, such as Hartford, TN, and Newport, TN, the county seat of Cocke County. The failure of the dam was caused by exceptional rainfall across the southern Appalachian mountain range generated from the remnants of Hurricane Helene.
