Dd No 6-22 is a local government-owned earthen dam located in Muscotah, Kansas, specifically on Wolfley Creek. Built in 1994 by King Engineering, this dam stands at a height of 26.6 feet and spans a length of 510 feet. Its primary purpose is debris control, with a storage capacity of 53.68 acre-feet and a normal storage level of 20.6 acre-feet. Despite its low hazard potential and moderate risk assessment, the dam is not state-regulated and has not been inspected since January 1995.

While Dd No 6-22 may not be under state jurisdiction or regulatory oversight, its presence on Wolfley Creek plays a crucial role in managing debris and maintaining the water quality in the area. The dam's uncontrolled spillway, at 30 feet wide, serves as a safety feature in case of high water levels. With a drainage area of 0.16 square miles and a maximum discharge capacity of 294 cubic feet per second, this dam contributes to the overall flood control efforts in the region.

Despite its age and lack of recent inspections, Dd No 6-22 continues to fulfill its purpose of debris control along Wolfley Creek. As an integral part of the local water resource management infrastructure, this earthen dam stands as a testament to the engineering efforts that safeguard communities from potential hazards and ensure the sustainable use of water resources in Nemaha County, Kansas.
