Culp & Culp Dam, located in Simpson, Kansas, is a privately owned structure that was completed in 1950. This earth dam, with a height of 23 feet, serves the primary purpose of water storage on the Lost Creek-TR river or stream. It has a maximum storage capacity of 97 acre-feet and a normal storage capacity of 34.2 acre-feet, covering a surface area of 6.42 acres.

The dam is regulated by the Kansas Department of Agriculture and has a significant hazard potential. Despite being in operation for several decades, the condition of Culp & Culp Dam has not been rated, and the last inspection was conducted in July 2003. The dam has not been modified in recent years, and there are no associated structures or outlet gates.

Enthusiasts interested in water resources and climate will find Culp & Culp Dam an intriguing subject for further study due to its historical significance, design characteristics, and regulatory oversight. Its location in Mitchell County, Kansas, and the involvement of state agencies in its permitting, inspection, and enforcement processes add layers of complexity to its operation and maintenance within the region's water management infrastructure.
