Canal Mauri
Tacna Department, Peru
Canal Mauri is a canal in Peru and Chile. It transfers water from the Mauri River watershed and transfers it into the Caplina River for irrigation purposes. An earlier canal Canal Uchusuma was constructed in the early 19th century and was replaced by the Canal Mauri. This canal collects water from several tributaries of the Mauri River (notably the Uchusuma River) and diverts it through Chilean territory into the Quebrada Vilavilani, a tributary of the Caplina River; from there it is later diverted for irrigation purposes in the Tacna region. The diversion has damaged wetlands in the region and consequently the expansion project "Vilavilani II" - which would take additional water directly from the Mauri River - has engendered opposition.
