Upper Snow Dam, located in Chelan, Washington, is a Federal-owned structure managed by the U.S. Bureau of Reclamation. Built in 1939, this dam on Snow Creek serves the primary purpose of water supply, with a storage capacity of 770 acre-feet. The dam stands at a height of 10 feet and is constructed on a rock foundation, supporting a length of 119 feet.

Despite its low hazard potential, Upper Snow Dam has been assessed to be in poor condition as of September 2018. The dam has undergone modifications in 1974, 1991, and 2001, primarily for mechanical improvements. With a moderate risk rating, it is important for ongoing risk management measures to be implemented to ensure the safety and integrity of the structure.

For water resource and climate enthusiasts, Upper Snow Dam presents a fascinating case study in the management of water supply infrastructure. With its historical significance and ongoing maintenance challenges, this dam serves as a reminder of the vital role that dams play in providing water resources while also highlighting the importance of monitoring and maintaining these structures for long-term sustainability in the face of changing environmental conditions.
