The Van Stone Tailings Dam, located in Stevens County, Washington, was completed in 1970 with a primary purpose of storing tailings. This earth dam, with a structural height of 90 feet and a length of 2000 feet, has a maximum storage capacity of 150 acre-feet and covers a surface area of 20 acres. Despite its significant hazard potential, the dam is in poor condition, as assessed in September 2021, raising concerns among water resource and climate enthusiasts.

Managed by a private owner, the Van Stone Tailings Dam is regulated by the Washington Department of Ecology and undergoes inspections every five years. The dam's poor condition and significant hazard potential highlight the importance of regular maintenance and risk management measures to ensure the safety of surrounding communities and the environment. With a drainage area of 0.04 square miles and offstream location, the dam's impact on water resources and climate in the region is a topic of interest for enthusiasts in the field.

As climate change continues to pose challenges to water resource management, the condition of dams like Van Stone Tailings Dam becomes increasingly critical. With its outdated Emergency Action Plan last revised in 2008 and no updated risk assessment or management measures in place, there is a pressing need for improved monitoring and maintenance to address potential risks associated with this structure. For water resource and climate enthusiasts, staying informed about the state of dams like the Van Stone Tailings Dam is essential for promoting environmental sustainability and community safety in the face of changing climatic conditions.
