Sibinacocha dam

In 1996 a 357 m long and 12 m high earth embankment was built at the outflow of the lake. The dam operated by EGEMSA (Empresa de Generación Eléctrica Machupicchu SA) increases the storage volume of the lake and regulates its discharge. The usable storage volume is 120 million m³. During the low-precipitation period, between 7 and 12 m³ / s of water can be released, which the Machupicchu hydropower plant downstream on the Río Urubamba can use.
