Zylstra Dam No 2, located in San Juan County, Washington, was completed in 1963 and is owned by the local government. The dam's primary purpose is irrigation, with a maximum storage capacity of 430 acre-feet and a normal storage capacity of 280 acre-feet. The dam is an earth-filled structure with a hydraulic height of 25 feet and a structural height of 19 feet, designed to regulate the flow of Tr-False Bay.

The dam is regulated by the Washington Department of Ecology and is subject to state inspection, enforcement, and permitting. Despite its low hazard potential, the dam's condition has not been rated and there is no Emergency Action Plan (EAP) in place. The last inspection was conducted in April 2019, and the dam is deemed to be in satisfactory condition. The dam has not been modified since its completion, and there are no associated structures or outlet gates.

Overall, Zylstra Dam No 2 plays a crucial role in supporting irrigation activities in the region, highlighting the importance of water resource management and infrastructure in mitigating the impacts of climate change. The dam's presence underscores the need for continued monitoring and maintenance to ensure its safe operation and effectiveness in water regulation. As climate enthusiasts, it is essential to recognize the critical role of dams like Zylstra Dam No 2 in sustaining water resources for agricultural and environmental purposes in the face of changing climate patterns.
