Stevenson Dam, located in Yakima, Washington, is a privately owned structure that plays a crucial role in providing recreational opportunities for water resource and climate enthusiasts. Completed in 1969, this earth dam stands at a hydraulic height of 17 feet and a structural height of 15 feet, impounding Tr-Wide Hollow Creek to create a storage capacity of 27 acre-feet. With a hazard potential classified as high and a fair condition assessment, regular inspections are conducted to ensure the dam's safety and integrity.

Managed by the Washington Department of Ecology, Stevenson Dam is situated in an area with a drainage area of 1.07 square miles and a maximum discharge capacity of 98 cubic feet per second. While the primary purpose of the dam is for recreation, it also serves as a vital structure for regulating water flow and storage in the region. The dam's location in Congressional District 04, represented by Dan Newhouse, further underscores its significance in water resource management and climate resilience efforts in the state.

Despite its modest size, Stevenson Dam stands as a testament to the importance of earth structures in supporting water management and recreational activities. As climate change impacts continue to shape water resource dynamics, the efficient operation and maintenance of dams like Stevenson are crucial in ensuring water security and environmental sustainability for generations to come.
