Beitey Lake Dam in Valley, Washington, is a private-owned earth dam completed in 1934 primarily for recreational purposes. With a height of 17 feet and a structural height of 15 feet, this dam holds a maximum storage capacity of 220 acre-feet and covers a surface area of 24.2 acres. Situated on the Tr-Colville River, this dam serves as a vital water resource for the region, with a normal storage capacity of 100 acre-feet and a drainage area of 3.1 square miles.

Despite its historical significance and recreational value, Beitey Lake Dam poses a high hazard potential with a poor condition assessment. The dam has been regulated and inspected by the Washington Department of Ecology, emphasizing its importance in ensuring public safety and environmental protection. The last inspection in November 2021 highlighted the need for improved maintenance and risk management measures to mitigate potential hazards.

As climate change continues to impact water resources and infrastructure, Beitey Lake Dam stands as a critical structure in need of ongoing monitoring and maintenance to ensure its long-term integrity and safety. With its location in a high-risk area and poor condition assessment, stakeholders must prioritize proactive measures to address potential risks and safeguard the surrounding community and ecosystem.
