Almost all of Chile's rivers are part of the Pacific Ocean basin.
Ljuta River
The river passes through the lands of the region of northern Chile - Arica y Parinacota. The source of the river is the western slopes of the Andes (province of Parinacota). The mouth of the river is the waters of the Pacific Ocean near the Peruvian border (slightly north of the city of Arica). The total length of the river is one hundred and forty-seven kilometers.
The source is the confluence of the Karakarani Creek and the Asufre River. After about thirty-six kilometers, the riverbed is locked into a canyon, and only after the water comes out on the plain again does Ljuta expand. The river flows into the waters of the Pacific Ocean, forming a wide delta.
The hydrology of the river is directly dependent on the rainfall. The rise in water is traditionally recorded in January and February. This annual phenomenon is called "Bolivian winter". The main tributaries are: Asufre; Karakarani (stream); Colpitas (stream); Sokoroma (stream).
Lauca river
Geographically, the river belongs to two states - Bolivia and Chile. The source of the river is the Chilean plateau (Arica-i-Parinacota region). After Lauca crosses the Andes, she ends up in the waters of Lake Coipasa (Bolivia). The total length of the river channel is two hundred twenty-five kilometers.
In its upper course, the river passes through the territory of the Lauca National Park (Parinacota province). The river is fed by the waters of Lake Kotakotani. The largest tributaries of the river are: Ancochalloanes; Viskachani; Cyburcan. The most important tributaries of the river are the left tributaries, as they carry glacial waters to Lauka. These are the Gualatiri and Chushavida rivers.
San Pedro river
San Pedro is a river passing through the northern part of Chile (El Loa province, Antofagasta region) and is a left tributary of the Loa River. The source of San Pedro is the junction of two rivers - Salal and Cajon. The total length of the river channel is seventy-five kilometers.
Tana River
The river is located in the northern part of Chile, passing through the territory of the Tarapaca region. The total length is one hundred and sixty-three kilometers. The source of the river is located slightly west of the Isluga volcano. The main part of the channel runs along the Pampa de Tamarugal gorges. The confluence is the waters of the Pacific Ocean (north of the village of Pisagua). The main tributaries of the river: Tiliviche; Retamilia.
Loa River
The Loa is the longest river in the country. The total length of the channel from the source to the mouth is four hundred and forty kilometers. The source of the river is the Andes (the slope of the Migno volcano). After the river descends from the mountains, its path passes through the territory of the Atacama Desert. The banks of the river in many places form oases. The mouth of the river is the Pacific Ocean. The river bed is the natural border between the Antofagasta and Tarapaca regions.
