Flying Joseph Dam in Idaho, completed in 2008, stands as a crucial structure regulating the waters of the Pahsimeroi and Salmon Rivers. This earth dam, with a height of 14 feet and a length of 1013 feet, serves a primary purpose of 'Other', supporting a normal storage capacity of 50.6 acre-feet. Despite its low hazard potential, the dam's condition assessment in 2020 was marked as poor, emphasizing the need for ongoing maintenance and monitoring.

Owned privately and regulated by the Idaho Department of Water Resources, Flying Joseph Dam plays a vital role in managing water resources in Custer County. Its foundation of rock and soil, along with a stone core, ensures structural integrity, while an uncontrolled spillway with a width of 13 feet helps manage excess water flow. With a moderate risk assessment, the dam requires attention to mitigate potential risks and safeguard surrounding communities in case of emergencies.

For water resource and climate enthusiasts, Flying Joseph Dam represents a key infrastructure in the intricate network of water management systems. Located at the confluence of two significant rivers, this dam not only provides essential storage but also poses challenges in terms of maintenance and safety. As efforts continue to assess and address the dam's condition, stakeholders must prioritize proactive measures to ensure the long-term sustainability and resilience of this critical water resource structure.
