Queens Bog Dam, located in King County, Washington, was completed in 1987 and serves as a vital structure for flood risk reduction along the Tr-Sammamish Lake. Owned and regulated by the Washington Department of Ecology, this earth dam stands at a hydraulic height of 12 feet and a structural height of 9 feet. With a storage capacity of 132 acre-feet, the dam covers a surface area of 17 acres and drains an area of 5.4 square miles. Despite its low hazard potential, the dam is not currently rated for its condition assessment.

Although the dam's primary purpose is flood risk reduction, it also serves as a critical component of the local water resource management system. The dam plays a significant role in protecting nearby communities from potential flooding events and ensuring the stability of the surrounding ecosystem. With a maximum discharge capacity of 80 cubic feet per second, the dam is well-equipped to handle varying water flow rates and maintain optimal water levels in the area.

As an integral part of the water infrastructure in Washington, Queens Bog Dam highlights the importance of sustainable water resource management and climate resilience. With its regulated state permitting, inspection, and enforcement processes, the dam demonstrates a commitment to maintaining the safety and functionality of water infrastructure in the region. As climate change continues to impact water resources, dams like Queens Bog Dam play a crucial role in adapting to evolving environmental conditions and ensuring the long-term sustainability of water management practices.
