The Río Grande-Colorado lies nearly in the center of Argentina near the Chilean border. This expedition was the first to put some of it's previously run pieces into a 15 day raft trip. The river begins high in the Andes and then enters arid basalt canyons forming some great scenery and whitewater. The Grande then flows into the Río Colorado and onward to the Atlantic Ocean just south of Bahía Blanca in eastern Argentina. The river is so special, it is under consideration to be declared a World Natural Heritage Site by UNESCO.
AT RISK OF BEING LOST:
A dam is proposed at Portazuelo del Viento on Río Grande. The project consists of not only a 597ft-high dam that will drown more than 20 miles of the river, it also will divert most of the river water into the Río Atuel drainage and thus remove water from the Payunia Reserve and from people living downstream in La Pampa. Furthermore, the overall project consists not only of a single dam - when the Chinese company Gezhouba (which built the destructive Three Gorges Dam on the Yangtze River) ends with this first project, it aims to build a complex of 4 additional massive dams downstream resulting in nearly a complete destruction of Río Grande-Colorado.
