Built in 1982 by the USDA NRCS, this earth dam serves the primary purpose of flood risk reduction along the South Platte River. With a height of 51 feet and a hydraulic height of 45 feet, it has a storage capacity of 3,148 acre-feet and covers a surface area of 148 acres.

Situated in a strategic location at S26, T.12N, R.47W, 6th PM, this dam plays a significant role in protecting the surrounding area from potential flood events. With a low hazard potential and a satisfactory condition assessment, it is inspected every three years to ensure its structural integrity. The dam's uncontrolled spillway, measuring 284 feet in width, allows for a maximum discharge of 7,659 cubic feet per second, further enhancing its flood management capabilities.

Managed by the local government and regulated by the Colorado Department of Water Resources, Floodwater Retention Dam Ss-3 stands as a testament to effective flood risk reduction infrastructure in the region. Its design and construction by the USDA NRCS have proven instrumental in safeguarding the community from potential flooding, making it a vital asset for water resource and climate enthusiasts alike.
