Private Dam, also known as Ksnoname 3914, is a privately owned earth dam located in Kenneth, Johnson County, Kansas. Built in 1970 by the design firm Payne & Brockway, this recreational dam stands at a height of 12.5 feet and has a hydraulic height of 24 feet, with a capacity of 30 acre-feet of water storage. It is situated along the Negro Creek-TR stream within the Tulsa District of the US Army Corps of Engineers.

Although Private Dam is not regulated or inspected by state agencies, it still poses a significant hazard potential. With a capacity to discharge up to 320 cubic feet per second, the dam's condition remains unrated, and no emergency action plan or risk assessment has been prepared. Despite these challenges, the dam continues to serve its primary purpose of recreation, offering opportunities for leisure activities in the surrounding area. Water resource and climate enthusiasts may find Private Dam an intriguing case study of a privately owned structure with important implications for safety and sustainability.
