The Cottonwood River is a 152-mile-long river in eastern Kansas, USA. It has been used by Native Americans for hundreds of years for hunting and fishing. The river flows through several counties and its basin is home to many small towns. The river's hydrology is influenced by rainfall and the presence of reservoirs and dams, such as the John Redmond Reservoir, Marion Reservoir, and Chase County Lake. These dams provide flood control, irrigation, and recreational opportunities for fishing, boating, and camping. The Cottonwood River is also an important source of water for agricultural uses such as crop irrigation and livestock watering. Despite occasional flooding, the river remains an important resource for the communities it serves.
