Wells, a hydroelectric facility located in Chelan Falls, Washington, harnesses the power of the Columbia River to generate electricity and support various purposes such as fish and wildlife ponds, irrigation, and recreation. Built in 1968 by the Bechtel Corporation, this gravity dam stands at 160 feet tall with a storage capacity of 500,000 acre-feet. Its controlled spillway and 11 other controlled outlet gates ensure the safe release of water, while its high hazard potential and very high risk assessment highlight the importance of effective risk management measures.

With a structural height of 160 feet and a length of 4,300 feet, Wells dam serves as a key player in the region's water resource management and climate resilience efforts. Managed by the Federal Energy Regulatory Commission, the dam plays a crucial role in regulating the flow of the Columbia River, supporting both local ecosystems and communities. Despite its high hazard potential, Wells dam continues to operate efficiently, providing clean energy and water resources to the surrounding areas while maintaining a strong commitment to safety and environmental stewardship.

As water resource and climate enthusiasts continue to monitor and assess the impacts of climate change on water infrastructure, facilities like Wells dam stand as vital assets in ensuring sustainable water management practices. The collaboration between federal agencies, local stakeholders, and the public utility sector is essential in safeguarding these critical resources for future generations. Wells dam's storied history and ongoing contributions underscore the importance of innovative solutions and strategic planning in addressing the challenges of a changing climate.
