The North Platte River

The 'North Platte River' is a tributary of the
Platte River, approximately 680 mi (1,094 km) long, in the
U.S. states of
Colorado,
Wyoming, and
Nebraska. It forms the Platte at its confluence with the
South Platte River in western Nebraska. The river provides the major avenue of drainage for eastern Wyoming and western Nebraska. Although it is not navigable, it has been an important route of transportation in the westward expansion of the
United States, providing the route of several of the major migration trails, including the
Oregon Trail and the
Mormon Trail.
Description
The North Platte rises in the
North Park valley of north central Colorado, near the town of
Walden, on the eastern slope of the
Park Range. It flows northward into Wyoming, along the western side of the
Medicine Bow Mountains. On the north end of the range it is joined by the
Medicine Bow River in the
Seminoe Reservoir, then downstream of the
Kortes Reservoir it is joined by the
Sweetwater River in the
Pathfinder Reservoir. Northeast of the reservoir it passes through the Alcova and Gray Reef Reservoirs and flows northeast between the
Granite Mountains to the west and the
Laramie Mountains to the east.
It emerges from the mountains near
Casper, where it flows east, along the northern reach of the
Laramie Mountains onto the
Great Plains. It flows southeast across the plains of eastern Wyoming, past the town of
Douglas and through
Glendo and
Guernsey Reservoirs. It then flows past the
Fort Laramie National Historic Site, where it is joined by the
Laramie River. It crosses into western Nebraska, flowing ESE between the cities of
Scottsbluff and
Gering. In
Keith County, the
Kingsley Dam forms
Lake C.W. McConaughy, the largest lake in Nebraska and a significant
irrigation and recreation facility for the region. East of the dam it flows nearly parallel to the South Platte, separated by only 5 mi (8 km) for a stretch of approximately 50 mi (80 km). It joins the South Platte to form the Platte just east of the city of
North Platte. Historically, this river used to be a mile wide in many places as evidenced by the old streambed and written records. By the time the North Platte reaches Paxton, NE it is a muddy creek due to the extensive water taken from it for irrigation.
In Colorado and Wyoming, the river is narrower and much swifter flowing than it is in Nebraska, where it becomes a
braided stream. The upper reaches of the river in the Rockies are popular for recreation rafting and
fly fishing for
rainbow trout and other sport fish. In western Nebraska, the banks and riverbed of the North Platte provide a green oasis amid an otherwise semi-arid region of North America. For this reason, the locals sometimes use the nickname "
Nile Valley" to refer to the North Platte Valley.
