Dd No 226 is a low hazard potential earth dam located in Nemaha, Kansas, along the NORTH FORK-TR river. This dam, with a height of 23.8 feet and a storage capacity of 126 acre-feet, serves as a crucial water resource for the area. Despite not being state regulated, the dam is maintained by the local government and has a moderate risk assessment rating of 3.

Constructed by MUETING ENGINEERING & SURVEYING,DUANE H MUETING, Dd No 226 has a spillway width of 40 feet and a maximum discharge capacity of 550 cubic feet per second. The dam's primary purpose and year of completion are unspecified, but its normal storage capacity of 33 acre-feet provides essential water supply for the surrounding area. While the dam is currently in a not rated condition assessment status, its low hazard potential and moderate risk assessment indicate the importance of regular monitoring and maintenance to ensure its safety and efficacy in managing water resources in the region.

With a surface area of 6 acres and a drainage area of 0.33 square miles, Dd No 226 plays a vital role in water management within the Kansas City District. The dam's uncontrolled spillway type and lack of outlet gates suggest a simplistic design, emphasizing the need for continued oversight and emergency preparedness. As climate change impacts water resources, understanding and maintaining infrastructure like Dd No 226 becomes increasingly important for ensuring water security and resilience in the face of evolving environmental challenges.
