General Description

The Cachapoal River is located in the O'Higgins Region, Region VI of the Republic of Chile. The Rio Cachapoal is generally not known as a whitewater river except for the small section of class II/III whitewater between the Termas de Cauquenes and Sauzal.

Most of the Cachopoal River is devoted to heavy industry and electrical production. On it’s northern banks, to the east of the city of Rancagua, lies the worlds largest underground copper mine, called “El Teniente” and owned by the Codelco corporation. The principal dam on the river is located at Coya near the confluence with the Rio Coya. The most important dam is in the region is located on the Rio Pangal, an upstream tributary of the Cachapoal River. These dams were built in 1911 and 1921 respectively to supply electricity and water to the copper mine. In 2004 they were sold to Pacific Hydro of Australia along with all of the water rights to the Upper Cachapoal River. Pacifico Hydro plans to further develop the Cachopoal River despite the environmental disaster it caused on the Tinguiririca River to the immediate south.

The river section between these two dams is often dry, as water is diverted for electrical production and use by the copper mine. However, if it is caught at the right time, reports have are that it can supply a good class IV/V run for about 6 miles (10 km).
