Coldwater Debris Dam, located in Castle Rock, Washington, was completed in 1981 by the US Army Corps of Engineers to primarily serve as a flood control structure on the North Fork of Coldwater Creek. This federal-owned earth dam stands at an impressive height of 200 feet and has a hydraulic height of 170 feet, with a length of 4200 feet. The dam has a storage capacity of 78,700 acre-feet, with a spillway width of 40 feet for uncontrolled release of excess water.
Managed by the Forest Service, Coldwater Debris Dam is crucial in mitigating flood risks in the region, although its hazard potential and condition assessment remain undetermined and not rated, respectively. The dam's risk assessment is moderate, indicating a potential for adverse consequences in the event of a failure. While the dam has not been regularly inspected since 2011, its emergency action plan status and adherence to guidelines are unknown, raising concerns about the readiness for potential emergencies.
Enthusiasts of water resources and climate resilience will find Coldwater Debris Dam to be a significant structure in flood management on the North Fork of Coldwater Creek. As a key federal-owned asset, the dam's structural integrity and emergency preparedness are essential considerations for ensuring the safety and protection of surrounding communities and the environment in the face of changing climate conditions and extreme weather events.
