Waukena Lake Dam, located in Glen, Montana, is a private dam constructed in 1930 by the USDA NRCS to primarily reduce flood risks in the area. The dam stands at a height of 12 feet with a length of 115 feet, providing a storage capacity of 169 acre-feet. Situated on Rock Creek, the dam is under the jurisdiction of the Walla Walla District of the US Army Corps of Engineers.

Despite its age, Waukena Lake Dam has a low hazard potential and is currently assessed to be in a condition that is not available. While the dam has not been inspected in recent years and lacks emergency action plans, it continues to serve its purpose of flood risk reduction effectively. With its historical significance and importance in protecting the surrounding areas, the dam remains a crucial infrastructure in the region's water resource management.

As a key structure in the local water management system, Waukena Lake Dam plays a vital role in safeguarding the community from potential flooding events. With its modest height and capacity, the dam exemplifies the importance of proactive measures in mitigating natural disasters and ensuring the resilience of water resources in the face of climate challenges. As water resource and climate enthusiasts, it is essential to recognize the value of such infrastructure in promoting sustainable practices and safeguarding the environment for future generations.
