The river was named for the red - bed country of its watershed . It is one of several rivers with that name . Although it was once a tributary of the Mississippi River , the Red River is now a tributary of the Atchafalaya River , a distributary of the Mississippi that flows separately into the Gulf of Mexico . It is connected to the Mississippi River by the Old River Control Structure . The south bank of the Red River formed part of the US -- Mexico border from the Adams -- Onís Treaty ( in force 1821 ) until the Texas Annexation and the Treaty of Guadalupe Hidalgo . The Red River is the second - largest river basin in the southern Great Plains . It rises in two branches in the Texas Panhandle and flows east , where it acts as the border between the states of Texas and Oklahoma . It forms a short border between Texas and Arkansas before entering Arkansas , turning south near Fulton , Arkansas , and flowing into Louisiana , where it flows into the Atchafalaya River . The total length of the river is 1,360 miles ( 2,190 km ) , with a mean flow of over 57,000 cubic feet per second ( 1,600 m / s ) at the mouth .

The North Fork Red River meets the southern and largest fork near the Texas -- Oklahoma border . The southern fork , which is about 120 miles ( 190 km ) long , is generally called the Prairie Dog Town Fork . It is formed in Randall County , Texas , near the county seat of Canyon , by the confluence of intermittent Palo Duro Creek and Tierra Blanca Creek . State Highway No. 78 Bridge at the Red River between Oklahoma and Texas , photographed on the Oklahoma side Crossing the Red River at the Texas -- Oklahoma border from I - 35 The Red River took a new channel near Natchitoches , Louisiana , and left behind Cane River Lake . The Red River turns and flows southeast through Palo Duro Canyon in Palo Duro Canyon State Park at an elevation of 3,440 feet ( 1,050 m ) , then past Newlin , Texas , to meet the Oklahoma state line . Past that point , it is generally considered the main stem of the Red River . Near Elmer , Oklahoma , the North Fork finally joins , and the river proceeds to follow a winding course east through one of the most arid parts of the Great Plains , receiving the Wichita River as it passes the city of Wichita Falls . Near Denison , the river exits the eastern end of Lake Texoma , a reservoir formed by the Denison Dam . The lake is also fed by the Washita River from the north . Point bars , abandoned meander loops , oxbow lakes in Lafayette and Miller counties , Arkansas After the river flows out of the southeastern end of the lake , it runs generally east towards Arkansas and receives Muddy Boggy Creek before turning southward near Texarkana . Soon after , the river crosses south into Louisiana . The sister cities of Shreveport and Bossier City were developed on either bank of the river , as were the downriver cities of Alexandria and Pineville . Where it is joined by the Ouachita River , its largest tributary , the river later broadens into a complex network of marshlands surrounding the Mississippi and Atchafalaya rivers . Its waters eventually discharge into the Atchafalaya River and flow eastward or southward into the Gulf of Mexico . In 1946 , the Red River flood spilled over into Pineville because of insufficient levee height and strength . However , the taller and stronger levee held in Alexandria . Willie E. Kees Jr. , the newly elected mayor of Pineville , worked to gain support for the Corps of Engineers to increase the height of the levee on the eastern side of the river to equal that in Alexandria . Tributaries ( edit ) Tributaries include the Little Red River , Prairie Dog Town Fork Red River , Salt Fork Red River , North Fork Red River , Pease River , Washita River , Kiamichi River , Little Wichita River , Little River , Sulphur River , Loggy Bayou ( through Lake Bistineau and Dorcheat Bayou ) as well as the Ouachita River ( also known as the Black River at that point ) not far ( at Acme , Louisiana ) from the mouth . Watershed ( edit ) The Red River 's watershed covers 65,590 square miles ( 169,900 km ) and is the southernmost major river system in the Great Plains . Its drainage basin is mostly in the states of Texas and Oklahoma , but also covers parts of Arkansas and Louisiana . Its basin is characterized by flat , fertile agricultural land , with only a few major cities . The drainage basin of the Red River is very arid and receives little precipitation . As a result , much of the river above the Texas -- Oklahoma border is intermittent , and until the river is past its great bend south in Arkansas , the flow varies widely . Most of the agriculture in the basin is sustained by groundwater , which is recharged with rainfall and riverflow . The lower course of the river flows through a series of marshes and swamps , where its flow is dramatically moderated . History ( edit ) Native Americans ( edit ) Native American cultures along the river were diverse , developing specialized adaptations to the many different environments . By the time of European contact , the eastern Piney Woods were dominated by the numerous historic tribes of the Caddoan Confederacy . They found plentiful game and fish , and also had good land for cultivating staple crops . The middle part of the Red River was dominated by Wichita and Tonkawa . This area was prairie , where Native Americans constructed portable and temporary tepees for housing . They practiced limited farming and followed game in seasonal , nomadic hunting cycles . The Plains division of the Lipan Apache dominated the western Red River area until the 18th century , when they were displaced by invading Comanche from the north . European - American Exploration and settlement ( edit ) Crossing the Red River near Granite , Oklahoma , 1921 . In 1806 , President Thomas Jefferson commissioned the Red River Expedition to explore parts of the new lands of the Louisiana Purchase by traveling up the Red River . He said it was `` in truth , next to the Missouri , the most interesting water of the Mississippi '' , in a letter to William Dunbar . Having threaded the maze of bayous at the river 's confluence , and the `` Great Raft '' of lodged driftwood , the expedition , was stopped by the Spanish near what is now New Boston , Texas . In 1806 , Lieutenant Zebulon Pike , under orders to ascertain the source of the Red River , ascended the Arkansas River , made his way downstream on what turned out to be the Rio Grande , and was sent home by the Spanish authorities . A more successful exploration of the river 's upper reaches to both its sources was the 1852 expedition under Capt . Randolph Barnes Marcy , assisted by Brevet Capt . George B. McClellan . The latter was important as a general in the American Civil War . In April 1815 , Captain Henry Miller Shreve was the first person to bring a steamboat , the Enterprise , up the Red River . Fulton and Livingston , who claimed the exclusive right to navigate Louisiana waters by steamboat , sued Shreve in the District Court of New Orleans . The judge ruled that the monopoly claimed by the plaintiffs was illegal . That decision , along with a similar outcome in Gibbons v. Ogden freed navigation on every river , lake or harbor in the United States from interference by monopolies . When John Quincy Adams became Secretary of State in 1817 , one of his highest priorities was to negotiate the boundaries of the Louisiana Purchase with Spain . He negotiated with the Spanish Minister to the United States , Luis de Onis , and finally concluded Adams -- Onis Treaty , also known as the Treaty of 1819 . The treaty defined the south bank of the river as the boundary between the United States and Spain . That boundary continued to be recognized when Mexico gained its independence from Spain , then again when Texas became independent from Mexico . It remained so until the United States Congress consented to the Red River Boundary Compact adopted by the states of Oklahoma and Texas , which set the jurisdictional boundary between Texas and Oklahoma at the vegetation line on the south bank , but left title of adjacent property owners at the south bank . In Louisiana , the area of present - day Natchitoches Parish was settled by French Creole and mixed - race Louisiana Creole people , starting before 1800 . The Cane River National Heritage Area marks this area of influence , with plantations and churches founded by Louisiana Creoles . Some of the sites are designated as destinations on the Louisiana African American Heritage Trail , designed in the 21st century . For nearly 100 years after the American Civil War , some of the plantations were the center of a large African American and Creole community life , whose people lived and worked in this area for generations . The area along the lower Red River of Grant Parish , Louisiana , and neighboring parishes were a mixture of hill country and cotton plantations , with white planters and subsistence farmers , and numerous African American slaves working the plantations in the ante bellum years . It was an area of heated social tensions and insurgency during and after the Reconstruction era . Grant was a new parish created by the Reconstruction legislature , which was trying to increase Republican Party representation . In 1873 , Grant Parish was the site of the Colfax massacre , caused by the political tension and violence arising from the disputed 1872 gubernatorial election and efforts by local whites to keep white supremacy . White militias , organized from nearby parishes , killed more than 100 freedmen , some of whom had surrendered as prisoners . In 1874 , such militias organized as the White League in Grant Parish , and other chapters were soon founded across the state . The Coushatta Massacre was attributed to the White League , which attacked Republican officeholders to run them out of office . The paramilitary groups intimidated and terrorized freedmen to keep them from the polls , and by the late 1870s , conservative Democrats had retaken political control of the state . Great Raft ( edit ) Main article : Great Raft Red River , Texas In the early 19th century , settlers found that much of the river 's length in Louisiana was unnavigable because of a collection of fallen trees that formed a `` Great Raft '' over 160 miles ( 260 km ) long . Captain Henry Miller Shreve began clearing the log jam in 1839 . The log jam was not completely cleared until the 1870s , when dynamite became available . The river was thereafter navigable , but north of Natchitoches it was restricted to small craft . Removal of the raft further connected the Red and Atchafalaya rivers , accelerating the development of the Atchafalaya River channel . In the 20th century , the interest group known as the Red River Valley Association was formed to lobby the United States Congress to make the river fully navigable between Alexandria and Shreveport , Louisiana . Leading supporters of the longstanding project were Louisiana Democratic senators Allen J. Ellender , J. Bennett Johnston and Russell B. Long , the Fourth District Congressman Joe Waggonner , and the late Shreveport Mayor Calhoun Allen . With the completion of the project , a lock system constructed by the US Army Corps of Engineers allowed navigation of barge traffic as far north as Shreveport . Greer County debate ( edit ) Specialists debate whether the North Fork or the Prairie Dog Town Fork is the true stem . Because of a cartographic error , the land between the north and south forks was claimed by both the state of Texas and the United States federal government . Randolph B. Marcy 's expedition followed the Prairie Dog Town Fork in 1852 . Originally called Greer County , Texas , the US Supreme Court ruled that it belonged to the United States , which at the time oversaw the Oklahoma Territory . That territory was later incorporated into the state of Oklahoma , whose southern border now follows the south fork . Today , the southern Prairie Dog Town Fork is considered the main fork , though the North Fork is as long and normally has a greater water flow . 2015 Louisiana flood ( edit ) In June 2015 , the Red River flooded parts of northeast Texas , southwest Arkansas , and Louisiana , from New Boston , Texas , to just south of Alexandria , Louisiana . Recreation ( edit ) Red River LA 2 Bridge , not the Jimmie Davis Bridge , atop the Red River between Bossier and Caddo parishes near Shreveport Popular pedestrian walkway along the Red River in Alexandria , Louisiana In 1943 , Denison Dam was built on the Red River to form Lake Texoma , a large reservoir of 89,000 acres ( 360 km ) , some 70 miles ( 110 km ) north of Dallas . Other reservoirs on the river 's tributaries serve as flood control .
