Lake Sibinacocha[1] (possibly from Quechua siwina whistle, qucha lake, lagoon) is a lake in Peru. It is ranked as the 22nd[2] highest lake in the world. It is located in the Cusco Region, Canchis Province, Pitumarca District. The lake is situated at a height of approximately 4873m (15,988feet), about 15.19 km long and 2.86 km at its widest point, and drains into the Amazon River. Sibinacocha lies in the Vilcanota Range, south of Chumpe and southwest of Condoriquiña.
The lake contains Inca artifact, some of which have been recovered from the lake.[3] Sacred sites around the lake have been studied as possible locations of the lost Ausangate temple. The area has been studied for its importance to the greater Urubamba-Vilcanota watershed. A high-altitude diver, Geoffrey Belter, died in 2014 while exploring the lake.
An earthen dam was erected at the lake in 1996.[4] It is 357m (1,171feet) long and 12m (39feet) high. The reservoir has a volume of 50000m2 and a capacity of 110000000m2. It is operated by EGEMSA.
