Spanish Chaco or El Chaco Lowland alluvial plain, south-central South America. An arid lowland, it is bounded by the Andes Mountains to the west and the Paraguay and Paraná rivers to the east; its northern and southern margins, generally considered to be a marshy area in Bolivia and the Salado River in Argentina, respectively, are less well defined. Its area is about 280,000 sq mi (725,000 sq km). The region's heartland, in the fork of the Paraguay and Pilcomayo rivers, was fought over by Bolivia and Paraguay in the Chaco War (1932-35). By a 1938 treaty a larger eastern part went to Paraguay and a smaller western part to Bolivia. Chaco's wildlife is abundant, and there are at least 60 known species of snakes. Cattle grazing is a major economic activity. The area remains isolated and is only sparsely populated
