The Smoky Hill River is a 575 mi river in the central Great Plains of North America, running through Colorado and Kansas.

Names

The Smoky Hill is named from the Smoky Hills region of north-central Kansas through which it flows. American Indians living along the Smoky Hill considered it and the Kansas River to be the same river, and their names for it included Chetolah and Okesee-sebo. Early maps of European explorers called the river (also in combination with the Kansas River) the River of the Padoucas as its source is located in what was then Padouca (Comanche) territory. The USGS lists several other names, including Chitolah River, Fork of the Hill Buckaneuse, La Fourche de la Cote Boucaniere, La Touche de la Cote Bucanieus, Manoiyohe, Pe P'a, Sand River, Shallow River, Smoky Creek, Branche de la Montagne a la Fumee, Ka-i-urs-kuta, Oke-see-sebo River, and Rahota katit hibaru.

Geography

The Smoky Hill River originates in the High Plains of eastern Colorado and flows east. Both the main course of it and of the North Fork Smoky Hill River rise in northern Cheyenne County, Colorado. The two streams converge roughly 5 mi west of Russell Springs in Logan County, Kansas. From there, the river continues generally eastward through the Smoky Hills region. The Saline River joins it in eastern Saline County. The Solomon River joins the Smoky Hill River in western Dickinson County. The Smoky Hill River joins the Republican River at Junction City, Kansas to form the Kansas River. The Smoky Hill River directly drains an area of 8810 sqmi. The combined Smoky Hill-Saline Basin drains 12229 sqmi. The entire Smoky Hill drainage basin covers approximately 20000 sqmi, including most of north-central and northwestern Kansas. Via the Kansas and Missouri Rivers, the Smoky Hill River is part of the Mississippi River watershed. The Smoky Hill River feeds two reservoirs: Cedar Bluff Reservoir in Trego County and Kanopolis Lake in Ellsworth County. The largest city along the Smoky Hill River is Salina, and other Kansas municipalities include Junction City, Ellsworth, Marquette, Lindsborg, and Abilene.

History

The earliest known reference to the river is on a 1732 map by French cartographer Jean Baptiste Bourguignon d'Anville who labeled it the "River of the Padoucas". A 1758 map referred to it as the "Padoucas River". An early reference to the river as the Smoky Hill was by American explorer Zebulon Pike during his 1806 expedition to visit the Pawnee. The Kansas–Nebraska Act of 1854 established Kansas Territory, including the entire length of the Smoky Hill River. With the onset of the Pike's Peak Gold Rush in 1858, an ancient American Indian trail along the river known as the Smoky Hill Trail provided the shortest, fastest route west across Kansas. Beginning in 1865, the trail was the route for the short-lived Butterfield Overland Despatch. To protect travelers, the U.S. Army established several forts along the trail, including Fort Downer, Fort Harker, Fort Hays, Fort Monument, and Fort Wallace. Before American colonization, the land along the Smoky Hill River was favored hunting ground for the Plains Indians. In 1867, the Comanche and the Kiowa, and in 1868, the Sioux and the Arapaho signed treaties withdrawing their opposition to the construction of a railroad along the Smoky Hill River. The Kansas Pacific Railway was completed in 1870, rendering the Smoky Hill Trail obsolete. In 1948, the U.S. Army Corps of Engineers finished construction of a dam on the Smoky Hill for flood control in southeastern Ellsworth County creating Kanopolis Lake. In 1951, the United States Bureau of Reclamation completed another dam on the river, for irrigation and flood control, in southeastern Trego County, Kansas, which created Cedar Bluff Reservoir.
