Frd No 9, also known as the Little Walnut Hickory Watershed Dam, is a significant water resource structure located in Butler County, Kansas. Owned by the local government and regulated by the Kansas Department of Agriculture, this earth dam was completed in 1966 with the primary purpose of flood risk reduction in the Middle Branch Little Walnut River.

Standing at a height of 32 feet and spanning a length of 1880 feet, Frd No 9 has a storage capacity of 2809.59 acre-feet and a normal storage level of 153 acre-feet. The dam has a low hazard potential and is currently rated in moderate condition. Despite not having an emergency action plan in place, the dam is regularly inspected by state authorities to ensure its safety and functionality in mitigating flood risks in the surrounding area.

With its strategic location and design, Frd No 9 plays a crucial role in managing water resources and reducing flood risks in the region. As climate change continues to impact weather patterns, structures like Frd No 9 become increasingly important for safeguarding communities and ecosystems against potential water-related hazards.
