where does the orange river start and end
Orange River The Orange River (from Afrikaans/Dutch: Oranjerivier) is the longest river in South Africa and the Orange River Basin extends extensively into Namibia and Botswana to the north. It rises in the Drakensberg mountains in Lesotho, flowing westwards through South Africa to the Atlantic Ocean. The river forms part of the international borders between South Africa and Namibia and between South Africa and Lesotho, as well as several provincial borders within South Africa. Except for Upington, it does not pass through any major cities. The Orange River plays an important role in the South African economy by providing water for irrigation and hydroelectric power. The river was named by Robert Jacob Gordon after the Dutch Royal House. Other names include Gariep River (used by the Khoi people[6]), Groote River or Senqu River (used in Lesotho).[7]
Arkansas River At 1,469 miles (2,364 km), it is the sixth-longest river in the United States,[5] the second-longest tributary in the Mississippi–Missouri system, and the 45th longest river in the world. Its origin is in the Rocky Mountains in Lake County, Colorado, near Leadville. In 1859, placer gold discovered in the Leadville area brought thousands seeking to strike it rich, but the easily recovered placer gold was quickly exhausted.[6] The Arkansas River's mouth is at Napoleon, Arkansas, and its drainage basin covers nearly 170,000 sq mi (440,300 km²).[3] In terms of volume, the river is much smaller than the Missouri and Ohio Rivers, with a mean discharge of roughly 41,000 cubic feet per second (1,200 m3/s).
