Prairie Dog Town Fork Red River - Geography

Geography

The Prairie Dog Town Fork Red River is the southernmost of two major forks which form the headwaters of the Red River. It begins as an ephemeral stream on the level surface of the Llano Estacado in Randall County, about 6.4 km (4 mi) northeast of Canyon, Texas. The stream initially runs northeastward then southeastward across Randall County, flowing through Palo Duro Canyon where it is fed by springs, providing a base flow that is often increased significantly by runoff from rainstorms. The stream continues in a southeasterly direction through southern Armstrong and northeastern Briscoe County where it exits Palo Duro Canyon and starts across the rolling red-bed country of central Hall and Childress counties, merging with Buck Creek and forming the Red River proper, 13 km south-southwest of Hollis, Oklahoma. When the Prairie Dog Town Fork crosses the 100th meridian at the eastern edge of Childress County, Texas, its south bank becomes the state boundary between Texas and Oklahoma.
