Located in Zumbro Falls, Minnesota, Sibley Pond is a privately owned water resource designed by the USDA NRCS to primarily reduce flood risks in the area. This Earth-type dam stands at a height of 25 feet with a hydraulic height and structural height of 25 and 26 feet, respectively. Completed in 1958, the pond has a storage capacity of 20 acre-feet and covers a surface area of 1 acre, serving a drainage area of 0.17 square miles.

With a spillway width of 15 feet and a maximum discharge capacity of 90 cubic feet per second, Sibley Pond poses a low hazard potential and has not been rated for its condition assessment. Despite its moderate risk level, the pond has not been inspected or assessed for emergency action plans, indicating a potential area for improvement in risk management measures. Situated within the St. Paul District, this offstream structure remains a critical component in the region's water resource management efforts, aligning with the overall goal of flood risk reduction in the area.
