Red River system, joining with the Thái Bình river system in the northeast, creates the Red River Delta - the second largest delta in Vietnam.  Because of the close relation between Red River system and Thái Bình river system, the two system are known as the common name "Red and Thai Binh rivers system".  Alluvium of the Red River system creates the central and south Red River Delta.  Two banks of the rivers are protected by a great dyke system.

Red River Expedition (1806): The Red River Expedition, also known as the Freeman-Custis Expedition, Freeman Red River Expedition, Sparks Expedition, or officially as the Exploring Expedition of Red River in 1806, was one of the first civilian scientific expeditions to explore the Southwestern United States.  It was ordered to find the headwaters of the Red River (Red River of the South) from the Mississippi River as a possible trading route to Santa Fe, then under Spanish colonial control in New Mexico; to contact Native American peoples for trading purposes; to collect data on flora, fauna, and topography, and map the country and river; and to assess the land for settlement.

2009 Fiesta Bowl: The 2009 Tostitos Fiesta Bowl game was a post-season college football bowl game between the Ohio State Buckeyes and the Texas Longhorns on Monday, January 5, 2009, at University of Phoenix Stadium in Glendale, Arizona.  Texas participated in the Fiesta Bowl because the Big 12 champion University of Oklahoma Sooners were participating in the 2009 BCS National Championship Game; however the bowl kept its ties to the Big 12 by selecting the Longhorns, who did not play in the championship game as they beat Oklahoma in the Red River Rivalry, 45-35, then lost to Texas Tech and Texas Tech in turn lost to Oklahoma and dictated that a tiebreaker would decide that the highest BCS ranked team for the Big 12 South the week of November 28, 2008 would be in the title game.  The Buckeyes were chosen as an at-large school as co-champions of the Big Ten Conference, having lost the right to play in the Rose Bowl due to a 13-6 loss to Penn State on October 25.
