Gs Dd No N-5 is a local government-owned dam located in Valley Falls, Kansas, designed by P.E. Wilbur Naylor. Completed in 1996, this Earth-type dam serves the primary purpose of flood risk reduction along the Nebo Creek-TR. With a height of 28 feet and a length of 600 feet, the dam has a storage capacity of 224.8 acre-feet and a drainage area of 0.79 square miles.

Despite its low hazard potential and moderate risk assessment, Gs Dd No N-5 has not been rated in terms of its condition assessment. The dam features an uncontrolled spillway with a width of 70 feet and has no outlet gates or associated structures. The last inspection took place in November 1995, with no subsequent inspections scheduled. The dam is regulated and permitted by the Kansas Department of Agriculture, with state jurisdiction and enforcement in place.
