Foster Dam, located in Todd, South Dakota, is a privately owned structure designed by Konechne Engineering and completed in 2015. This earth dam stands at a height of 14 feet and spans 800 feet across Sand Creek-TR. With a storage capacity of 243 acre-feet and a maximum discharge of 540 cubic feet per second, Foster Dam serves the primary purpose of water resource management in the region.

Despite being rated as having a low hazard potential, Foster Dam is considered to have a moderate risk level, with a risk assessment score of 3. While the dam's condition is currently not rated, it is inspected, permitted, and regulated by the South Dakota Department of Environment and Natural Resources (DENR) on a regular basis. The dam features an uncontrolled spillway with a width of 40 feet and is equipped with outlet gates for water release when necessary.

For water resource and climate enthusiasts, Foster Dam presents an interesting case study in dam infrastructure management and risk assessment. Its strategic location and design make it a vital component in the local water supply network, highlighting the importance of proper maintenance and regulatory oversight to ensure its continued safe operation in the face of changing environmental conditions.
