SAN PEDRO DE INACALIRI RIVER

'San Pedro de Inacaliri River', or called simply 'San Pedro River', is a river of Chile located in El Loa Province, Antofagasta Region. It begins at the confluence of the rivers Silala and ''Cajón'', at an elevation over 4,000 m asl.
A part of its flow is diverted (between 50 and 60 l/s) and conducted across the desert to Chuquicamata for domestic water supply. About 8 km south, the waters of the river disappear in a floodplain area to reappear 15 km downstream at the so-called ''Ojos del San Pedro'' in the form of a partially overground stream, at the eastern border of a salt flat with a surface of 5 km².
Before discharging into Loa River, the river skirts the San Pedro volcano, where it has carved a 100-m-deep canyon through a rhyolite lava flow.
