description
The Río Maipo is one of the longest and most important rivers in Chile with around 250 km. The headwaters are located on the border with Argentina, in the very southeast of the capital region in the municipality of San José de Maipo . There in the Andes in the Los Nacimientos sector at the foot of the Maipo volcano, the water runoff from the western and southern slopes of the volcanic cone and from the south-facing mountains of the caldera boundary collect at an altitude of 3,135 m and form the Río Maipo through their confluence. From Los Nacimientos the Río Maipo initially flows with an average gradient of 2.9% to the northwest to the mouth of the Río Volcán, 62 km away, near the town of San Gabriel. After another 2 km the Río Yeso and after another 25 km the Río Colorado flows into the Maipo. There the river changes direction to the west.

The river, which is constantly growing due to its numerous tributaries, overcomes a considerable gradient that is used by hydropower plants to generate electricity or for rafting . The Maipo Gorge, called Cajón del Maipo , and some of its side valleys were already settled in prehistoric times, as numerous archaeological finds show. Today it is the municipality of San José de Maipo , whose widely scattered districts line up there on its banks. The Cajón del Maipo has been a popular tourist attraction and vacation area since the 19th century .
After a total of 110 km, the Río Maipo leaves the Andes Cordillera and enters the Maipo plain at Puente Alto , which is almost 800 m above sea level there. The Río Mapocho , which comes from Santiago, flows into the vicinity of Talagante . After crossing the coastal cordillera , the Río Maipo reaches the village of Llolleo near the port city of San Antonio , where it flows into the Pacific Ocean .
The source region Los Nacimientos , 3135 m above sea level , 34 ° 14 ' S , 69 ° 51' W . Three streams, which in turn form from numerous rivulets, unite here to form the Río Maipo.
The Río Maipo flows over 110 km in the deep gorges through the Andes and has developed into a raging river that for hydropower plants or rafting is used. The Cajón del Maipo (Spanish for Maipo Gorge) is an important holiday region for domestic and foreign tourists.
The Maipo River meanders past numerous cities through the Maipo Plain and the coastal cordillera to the Pacific coast . The sand and gravel washed up from the mountains are mined in the river bed . The agricultural irrigation of the region through which it flows takes place for the most part from its river water.
The Río Maipo often carries so much water that it still reaches the estuary in Llolleo despite considerable withdrawals for intensive irrigation and drinking water production.
