Site 152, located in Wabaunsee, Kansas, is a crucial structure for flood risk reduction along the Mill Creek-TR river. Completed in 2002, this earth dam stands at a height of 31 feet and spans 480 feet in length, with a storage capacity of 127 acre-feet. The dam serves a primary purpose of flood risk reduction and is regulated by the Kansas Department of Agriculture, ensuring state jurisdiction, permitting, inspection, and enforcement.

Despite its low hazard potential, Site 152 has a moderate risk assessment rating of 3, indicating the need for ongoing monitoring and risk management. The dam's spillway type is uncontrolled, with a width of 40 feet, capable of handling a maximum discharge of 759 cubic feet per second. The surrounding area has a drainage area of 0.51 square miles, with a normal storage capacity of 15.3 acre-feet and a surface area of 3.02 acres.

In the event of an emergency, the dam does not have outlet gates, but the state agency is responsible for emergency action planning. The structure has not been rated for condition assessment, but with regular inspections and risk management measures, Site 152 plays a vital role in protecting the local community from potential flood events.
