Thode Dam, located in Lewis, Washington, was completed in 1987 and stands at a hydraulic height of 12.1 feet, serving as a crucial off-stream barrier on Mill Creek. With a total length of 450 feet and a maximum storage capacity of 24 acre-feet, this private-owned earth dam plays a pivotal role in water resource management in the region. The dam is regulated, permitted, inspected, and enforced by the Washington Department of Ecology, ensuring its structural integrity and compliance with state regulations.

Despite its fair condition assessment and a high hazard potential, Thode Dam is equipped to handle a maximum discharge of 4.12 cubic feet per second. Its emergency action plan was last revised in April 2021, emphasizing the importance of preparedness and risk management. With a history of periodic inspections and a designated inspection frequency of 5 years, the dam remains a vital infrastructure for water storage and flood control in the area. Enthusiasts of water resources and climate will find Thode Dam to be a captivating example of human intervention in maintaining sustainable water systems in Washington.

In the face of changing climatic conditions and increasing water stress, Thode Dam represents a critical piece of infrastructure for water resource enthusiasts to study and understand. Its role in managing water flow, storage, and flood control on Mill Creek highlights the importance of thoughtful design, regulation, and maintenance in ensuring the long-term viability of water resources. As climate enthusiasts explore the intersection of infrastructure and environmental conservation, Thode Dam stands as a tangible example of human ingenuity and responsibility in safeguarding water sources for future generations.
