Red River

The Red River, or The Red River of the South, is a major tributary of the Atchafalaya and Mississippi Rivers located in the United States of America. The red-bed country of its watershed is the source for the river's name. There are many rivers with the same name. It is the second largest river basin in the southern Great Plains. At Texas Panhandle it rises in two branches and then flows east, it then acts as border between Texas and Oklahoma. It also forms a short border between Texas and Arkansas, turning south near Fulton, Arkansas and flowing into Louisiana. The length of the river is 1,360 miles (2,190 km).

The southern and largest fork of the river, is generally called the Prairie Dog Town Fork. It is formed by the confluence of intermittent Palo Duro Creek and Tierra Blanca Creek, in Randall County, Texas near the county seat of Canyon.
Near Natchitoches, Louisiana, and left behind Cane River Lake, the river changes its course.

At the Palo Duro Canyon in Palo Duro Canyon State Park, Red River turns and flows southeast through an elevation of 3,440 feet (1,050 m). After the meeting the north fork near Elmer, it continues to follow winding route through arid parts of Great Plains. While passing the Wichita Falls, the river receives from the Wichita River as well. Near Denison, the Red river along with Washita river from north fills Lake Texoma.

The river then runs towards Arkansas and receives from Muddy Boggy Creek and then turns southwards near Texarkana. Before spreading into marshlands near Atchafalaya and Mississippi river, the river crosses Louisiana to bisect Shreveport and Bossier City. Its waters eventually discharge into both rivers, and then into the Gulf of Mexico.
