Dean Springs Dam, located in Natrona, Wyoming, stands as a testament to the Bureau of Land Management's commitment to debris control. Completed in 1963, this gravity dam on Dean Springs Draw serves the critical purpose of preventing debris buildup and ensuring the smooth flow of water. With a structural height of 30 feet and a hydraulic height of 25 feet, this dam plays a crucial role in managing the 4.59 square miles of drainage area it oversees.

Despite its low hazard potential, the dam's condition assessment is marked as unsatisfactory, raising concerns for its long-term effectiveness. In 2017, an inspection revealed the need for maintenance and potential improvements to meet regulatory standards. While the dam has a moderate risk assessment rating of 3, there is currently no detailed risk management plan in place. As water resource and climate enthusiasts, staying informed about the upkeep and potential enhancements of Dean Springs Dam is essential to ensuring its continued functionality and environmental impact.

As a Federal-owned structure managed by the Bureau of Land Management, Dean Springs Dam plays a crucial role in water resource management in the region. With a storage capacity of 18.36 acre-feet and a normal storage level of 9 feet, this dam not only controls debris but also contributes to the overall ecosystem health. While its uncontrolled spillway and lack of outlet gates may pose challenges, the dam's strategic location and design make it a key asset for maintaining water flow and mitigating potential hazards. Keeping a close eye on the dam's condition, inspection frequency, and risk assessment is vital for safeguarding water resources and climate resilience in the area.
