Pathfinder NWR protects habitat around a Bureau of Reclamation reservoir located in a remote area of Wyoming, about 50 miles from the city of Casper. The refuge consists of four units around the reservoir, totaling over 16,000 acres that are all open to hunting. The refuge is an important waterfowl migration stopover on the western edge of the Central Flyway. Since the reservoir fluctuates by as much as 50 feet each year, it can be difficult to manage for waterfowl habitat, but hunters will find good hunting in created wetland areas. The refuge also includesand grassland habitats, providing good food and cover for mule deer, pronghorn, rabbits and sage grouse. All of these species may be hunted according to Wyoming regulations.
