Arikaree River

The Arikaree River is a 156-mile-long (251 km) river in the central Great Plains of North America. It lies mostly in the American state of Colorado, draining land between the North and South Forks of the Republican River, and it flows into the North Fork in Nebraska after flowing a short distance through Kansas. It is a designated area within the Colorado Natural Areas Program to protect native and uncommon species that may be endangered or threatened. The Arikaree River is shrinking due to groundwater pumping at a rate that exceeds the recharge rate of the Ogallala Aquifer, from which the Arikaree River is fed. It is estimated that the Arikaree River will dry about one-half mile by 2045.

Flows through: United States.
