Beaver River (Oklahoma)

From Wikipedia, the free encyclopedia

The Beaver River is an intermittant river in Oklahoma that drains most of the Oklahoma Panhandle. The headwaters of the Beaver River are at the convergence of the Corrumpa, Rafael, and Cienequilla Creeks west of Grenville, New Mexico. It flows from Union County, New Mexico across the three Oklahoma Panhandle counties, Cimarron, Texas, and Beaver. At Ft. Supply in Harper County, Oklahoma, the Beaver comes to a confluence with Wolf Creek and becomes known as the North Canadian River.

The Beaver River and its tributaries flow with water intermittently, after rain falls or snow melts. The area drained by the Beaver River in the high plains of northeastern New Mexico and the Oklahoma and Texas panhandles receives on average less than 8 inches (200 mm) of rain annually.
