Pathfinder Reservoir is located on the North Platte River 47 miles
southwest of Casper, in Carbon and Natrona counties. You can access
Pathfinder Reservoir from U.S. 220 via County roads 408 or 410. Map
Pathfinder Dam and Reservoir are part of the North Platte Project.
Pathfinder Dam is one of the first constructed by the
Reclamation Service (now the Bureau of Reclamation). Listed in the
National Register of Historic Places, Pathfinder Dam is the primary
historic attraction at the reservoir. Construction of the masonry dam
between 1905 and 1909 was a major engineering feat.
A small interpretive center is located in the historic dam tender's
house. The dam is in a granite canyon on the North Platte River
about three miles below its junction with the Sweetwater River.
Pathfinder National Wildlife Refuge
Parts of the reservoir are included in the Pathfinder
National Wildlife Refuge. There are five campgrounds and three boat
ramps. Available fish species include brown trout, cutthroat trout,
rainbow trout, ohrid trout, and walleye. Rainbow and cutthroat trout are
stocked annually in the reservoir.
The Pathfinder National Wildlife Refuge consists of 16,807 acres and
is an overlay project on part of the Bureau of Reclamation's Pathfinder
Reservoir in south central Wyoming. The Wildlife Refuge is in the
northern section of Pathfinder Reservoir covering Bishop's Point and
Sweetwater arm to the west.
At low reservoir levels, much of the refuge is bare mud flat with
some marsh adjacent to the inlets. The upland portion is grassland
interspersed with sagebrush flats. The upland portion of the refuge
bounds the refuge in narrow strips, itself bounded by public lands used
for grazing of livestock.
Pathfinder Interpretive Center
The Pathfinder Interpretive Center and 1.7-mile interpretive trail
are located near the dam. The interpretive trail may be accessed across
the historic suspension bridge or from the dam. The five campgrounds are
Bishop's Point, Diabase, Sage, Weiss, and Wolf Point.
Marina services are available at the Pathfinder marina. The
water levels at Pathfinder Reservoir vary greatly. Campsites may be at
the waters' edge or 1,500 feet away depending on drought conditions. An
RV dump site is located across from Weiss Campground just past the
Natrona County Roads, Bridges, and Parks Department
