The Río Lauca rises on Chilean territory in the marshes of Parinacota and is fed with water from Lago Chungará , Lago Cotacotani , and Lago La Cueva. The Río Lauca flows 76 km in Chilean territory and takes in water from the Río Blanco, Río Portales and Río Guayatire. At Macaya (18 ° 35 'S, 69 ° 5' W) the Río Lauca flows into Bolivian territory. When the water level is low, the river carries 3 cubic meters / sec. Water.
The Río Lauca flows into the Salar de Coipasa , the second largest salt lake in Bolivia. This is located at an altitude of 3680 m in the Andes .
The Río Lauca has a length of about 225 kilometers, of which about a third is in the Región de Tarapacá in Chile and two thirds in Bolivia.
In 1949 a border dispute arose over the water rights on the Río Lauca between Bolivia and Chile. 1,975 new negotiations started, but in 1978 interrupted again.
