Río Limay
Río Negro
The Limay River originates from Lake Nahuel Huapi in Patagonia, Argentina, and flows northeast for approximately 500 km, forming the border between Neuquén and Río Negro provinces. It converges with the Neuquén River at the city of Neuquén, giving rise to the Río Negro. Its basin covers around 63,700 km² and includes a network of interconnected lakes such as Nahuel Huapi, Correntoso, Moreno, and Gutiérrez. The river is renowned for its clear, transparent waters, a characteristic reflected in its Mapuche name meaning "transparent" or "limpid." The Limay supports a rich trout population, making it popular for fishing, kayaking, and rafting activities. Several hydroelectric dams, including Alicurá, Piedra del Águila, Pichi Picún Leufú, El Chocón, and Arroyito, harness its flow, leveraging the elevation drop from Lake Nahuel Huapi at 764 meters above sea level. Near the river, the only heavy water plant in South America operates, fed by the Limay's waters. The river's significant flow and natural beauty make it an important natural and economic resource in Patagonia.
