Pathfinder Dam is a masonry dam, located on the North Platte River, approximately 47 miles (76 km) southwest of Casper, Wyoming. It was constructed from 1905 to 1909 as part of the North Platte Project and has been modified several times since then. It is included on the National Register of Historic Places. Construction of the dam created Pathfinder Reservoir which provides water storage for 226,000 acres (910 km2) of irrigation in Wyoming and Nebraska.[2] The dam is named for General John Charles Fremont, who had explored the area in 1842 and was nicknamed the "Pathfinder of the West."
