Dd No 128, also known as Wet Walnut Watershed Dam No 128, is a crucial flood risk reduction structure located in Bazine, Kansas. Owned by the local government and regulated by the Kansas Department of Agriculture, this earth dam was designed by the USDA NRCS and completed in 1975. With a height of 20 feet and a capacity of 568 acre-feet, this dam plays a vital role in controlling the flow of Walnut Creek-TR and protecting the surrounding area from potential flood events.

Having a low hazard potential and a moderate risk assessment rating, Dd No 128 has not been rated for its condition assessment but is inspected periodically to ensure its structural integrity. The dam features an uncontrolled spillway with a width of 80 feet and no outlet gates. Despite its age, this dam continues to serve its primary purpose of flood risk reduction effectively. With its location in Ness County, Kansas, this structure is a key component in the water resource management of the region and highlights the importance of maintaining and monitoring infrastructure to mitigate potential risks associated with extreme weather events and climate variability.
