Private Dam, located in Stilwell, Kansas, was completed in 1996 by designer Harold A. Phelps, P.E. This privately owned earth dam serves multiple purposes, including fire protection, stock, and small fish pond management. With a height of 21 feet and a length of 750 feet, the dam has a storage capacity of 125 acre-feet and a surface area of 10.8 acres.

Although not regulated by the state and without a state permit or inspection, Private Dam has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment. The dam is situated on Wolf Creek-TR and falls under the jurisdiction of the Tulsla District of the US Army Corps of Engineers. It is notable for its lack of spillway and outlet gates, representing a unique private water resource in the region.

Despite its lack of state oversight, Private Dam remains a significant feature in the water resource landscape of Johnson County, Kansas. Its construction, ownership, and purpose reflect the intersection of private interests and public water resource management. For enthusiasts of water resources and climate, Private Dam offers a case study in the complexities of dam ownership, regulation, and maintenance.
