Kirwin Dam, located in Phillips County, Kansas, along the North Fork Solomon River, is a federal flood risk reduction structure managed by the Bureau of Reclamation. Completed in 1954, this earth dam stands at 169 feet in height and spans over 12,600 feet in length, with a storage capacity of over 500,000 acre-feet. The dam serves multiple purposes, including flood risk reduction and irrigation, making it a vital resource for the region.

With a high hazard potential and a moderate risk assessment, Kirwin Dam plays a crucial role in managing water resources and mitigating potential disasters in the area. While the condition assessment is not available, regular inspections and emergency action plans are in place to ensure the safety and integrity of the structure. With Roger W. Marshall representing the district, the dam continues to be a key asset in safeguarding the community and surrounding areas from the impacts of extreme weather events and flooding.
