Lynx Dam, located in Natrona, Wyoming, was completed in 1956 by the Bureau of Land Management and serves as a crucial structure for debris control on Lynx Draw. The dam, a gravity type with a hydraulic height of 26 feet and a structural height of 31 feet, provides a storage capacity of 17.7 acre-feet and covers a surface area of 10.7 acres. Despite its low hazard potential, the dam's condition assessment is currently unsatisfactory, highlighting the need for ongoing maintenance and inspection.

Managed by the Bureau of Land Management, Lynx Dam is regulated by the Wyoming State Engineer's Office, with state permitting, inspection, and enforcement in place. The dam has a moderate risk assessment rating of 3, indicating potential vulnerabilities that require attention. While the dam does not have outlet gates, it features an uncontrolled spillway with a width of 2 feet and a maximum discharge capacity of 290 cubic feet per second. The last inspection in July 2017 revealed the dam's condition as unsatisfactory, underscoring the importance of regular monitoring and upkeep to ensure its continued safety and functionality.

As a key water resource infrastructure in Wyoming, Lynx Dam plays a vital role in managing debris and protecting the surrounding area from potential hazards. With Liz Cheney representing the area in Congress, continued collaboration between federal and state agencies is essential to address the dam's maintenance needs and mitigate any risks associated with its operation. Water resource and climate enthusiasts are encouraged to monitor updates on Lynx Dam's condition and support efforts to ensure its resilience and longevity for the benefit of the community and the environment.
