Pilcomayo (in Hispanicized spelling)[2] (QuechuaPillkumayu or Pillku Mayu, pillku red, mayu river,[3] "red river", GuaraniYsyry Araguay[ʔɨsɨˈɾɨʔaɾaɰʷaˈɨ]) is a river in central South America. At 1,100 kilometres (680 mi) long,[4] it is the longest western tributary of the Paraguay River. Its drainage basin is 270,000 square kilometres (100,000 sq mi) in area, and its mean discharge is 200 cubic metres per second (7,100 cu ft/s).[4]
Along its course, the Pilcomayo silts up and splits into two main branches, North and South. After some distance, these branches rejoin to form the Lower Pilcomayo.[4]
The river basin is home to approximately 1.5 million people: one million in Bolivia, 300,000 in Argentina, and 200,000 in Paraguay.
The Nakotoi Indian Tribe resides in the southern region of the Pilcomayo, a region located along the river in central Paraguay.[8] The aborigines of this tribe are descendants of the highly renowned Redskin Tribe.[8] The Natokoi treated all neighbors as enemies, but none more so than the Tobas Tribe and the Nimká Tribe, their respective neighbors to the southwest and northeast.[8] Guerrilla warfare has long existed between the tribes, isolating the tribe from direct intercourse with the European settlers in the late 19th century.[8] Men of this tribe are generally tall and skinny, built like hunters or warriors, whereas women are short in size.[9] The Natokoi dress in a rug, fastened around the waist-line.[9]
