Alcova in Natrona County, Wyoming — The American West (Mountains)
Pathﬁnder Dam Construction
Pathfinder Dam was built between 1905 and 1909 and cost over two million dollars. It is located in a narrow canyon cut by the North Platte River through Precambrian basement rocks. It is a masonry arch structure built entirely of huge blocks quarried from the same Precambrian formations. The task of cutting, transporting and fitting the massive blocks severely tested the engineering skills of the day. Pathfinder Dam stands as a civil engineering landmark.
Pathfinder Dam stands 214 feet high and measures 432 feet across its crest. The Reservoir behind it holds over a million acre-feet (an acre of water a foot deep), creating a water sports area in the high, dry central Wyoming desert. Other dams named Seminoe, Kortes, Alcova, Grey Reef, Glendo and Guernsey would follow to further control and utilize waters from the North Platter waters.
Pathfinder Dam was named to honor General John C.
Erected by Wyoming State Parks and Cultural Resources.

Pathfinder Dam is one of the first constructed by the brand new U.S. Reclamation Service (todayís Bureau of Reclamation), created to administer the Reclamation Act of 1902, which committed the Federal Government to build irrigation works--dams, canals and reservoirs--in 16 arid and semi-arid states of the American West.
