Designed by Novak & Lay, this earth dam stands at a height of 30 feet with a length of 850 feet, providing a storage capacity of 197.6 acre-feet. The dam has a low hazard potential and is not currently rated for its condition.

Despite being last inspected in 1994, with no inspection frequency specified, Dd No 27-31 (Scoby) is regulated, permitted, and inspected by the Kansas Department of Agriculture. The dam features an uncontrolled spillway with a width of 60 feet and a maximum discharge of 1973 cubic feet per second. With a moderate risk assessment score of 3, the dam does not have an emergency action plan in place, posing potential challenges in the event of a flood or other emergency situation.
