The Arikaree River is a 156-mile-long (251 km) tributary of the Republican River that starts near Limon in Lincoln County, Colorado. The river flows east into Kansas, crossing the extreme northwestern corner of that state before entering Nebraska. North of Haigler in Dundy County, Nebraska, the Arikaree River joins the North Fork Republican River to form the Republican River.
The point where the Arikaree River flows out of Yuma County, Colorado, and into Cheyenne County, Kansas, is the lowest point in the State of Colorado at 3,317 feet (1,011 m) elevation. This crossing point holds the distinction of being the highest low point of any U.S. state. It is higher than the highest points of 18 states and the District of Columbia.
