Pathfinder is a significant federal-owned structure located in Natrona, Wyoming, along the North Platte River. Built in 1909 by the Bureau of Reclamation, this masonry dam stands at 214 feet tall and serves multiple purposes, including hydroelectric power generation and irrigation. With a storage capacity of over 1 million acre-feet and a maximum discharge of 50,310 cubic feet per second, Pathfinder plays a crucial role in water resource management in the region.

The dam has a high hazard potential and is regulated by the Bureau of Reclamation, which also conducts inspections and operations. Despite its age, Pathfinder's condition assessment is listed as "Not Available," highlighting the need for ongoing monitoring and maintenance to ensure its structural integrity. The dam's emergency action plan was last revised in April 2020, emphasizing the importance of preparedness for potential risks and emergencies associated with the structure.

Pathfinder's presence on the North Platte River not only contributes to the region's water supply and energy needs but also underscores the intersection of water resource management and climate resilience. As climate change continues to impact water availability and extreme weather events, the role of infrastructure like Pathfinder in ensuring water security and safety becomes increasingly vital. Efforts to enhance risk assessment, emergency preparedness, and maintenance will be crucial in safeguarding this critical water resource infrastructure for the future.
