Maipo River
The Maipo River is the main river flowing through the Santiago Metropolitan Region and the Valparaiso Region of Chile. It is located just south of the capital of Santiago. The Mapocho River, which flows through central Santiago, is one of its tributaries. Its headwaters are on the west slope of Maipo volcano, in the Andes. The Maipo River is by far the major source of irrigation and potable water for the region.Course
In its upper course the river runs as an entrenched torrent through the Andes mountains. Here, it receives three major tributaries: the El Volcán River, the Yeso River and the Colorado River. After leaving the Andes, the Maipo flows through the valley that bears its name, which is one of the principal wine-producing region in Chile. The Maipo River travels before emptying into the Pacific Ocean, near the locality of Llolleo, south of the port of San Antonio.
