Located in Louisville, Kansas, the Dd No 50 (Dave Doperalski) dam was completed in 1990 by USDA - SCS and serves as a crucial flood risk reduction structure along the Rock Creek-TR. Standing at a height of 29.5 feet with a length of 810 feet, this earth dam provides a maximum storage capacity of 103 acre-feet, with a normal storage level of 14 acre-feet and a surface area of 3.2 acres. Despite its low hazard potential and moderate risk assessment, the dam is not currently rated for condition assessment.

Owned by the local government and with no state jurisdiction, regulation, permitting, inspection, or enforcement, the Dd No 50 dam is primarily designed for flood risk reduction purposes. With a spillway width of 80 feet and uncontrolled spillway type, the dam has no associated structures or outlet gates. While lacking in emergency action plan preparation and guidelines compliance, the dam remains an essential infrastructure for water resource management in the area, supporting the community with its risk management measures and operations.
