Lake Aricota[1][2][3] (possibly from Aymara ari pointed, sharp, quta lake)[4] is a lake in Candarave Province, region of Tacna, Peru. It has an elevation of 2,800 metres (9,186 ft) above sea level.[2][3]

Geography[edit]

The lake originated when debris flows in steep canyon walls dammed the Callazas River.[2] The waters of the lake are currently diverted to a hydroelectric plant, which has lowered the lake level from ~800.000 m3 in 1967 to a monthly average of 140.000 m3 in 2000.[2] Main inflow sources of the lake are the Callazas River and the Jaruma creek.[2] The main outflow is due to seepage through the debris dam to the Curibaya River (although hydroelectric use could count also).[2]

Waters of Lake Aricota have a high arsenic content as the waters of Callazas River and Salado River (a tributary of Jaruma Creek)[1] pass through the Yucamane volcanic area.[5]
