Weenhayek
The Weenhayek are an Indigenous people of the Pilcomayo River and the northern Chaco. Their language belongs to the Mataguayan family, related to Wichí varieties spoken farther south. Communities on both banks of the Pilcomayo have long depended on its fish, particularly during seasonal migrations upstream. The river descends from the Andes into a flat country of woodland and wetlands, where its waters and channels change with the seasons.
