Limay River, River system in Patagonia, Argentina
The Limay is a river system in southern Patagonia that flows about 380 kilometers from a large mountain lake through multiple provinces. Along its course it eventually meets another major river, combining their waters into a larger waterway.
The river was used by Mapuche peoples for centuries and shaped human settlement in the region long before European arrival. In modern times, a series of dams was built along its length for power generation, transforming the river's economic role.
The river's name comes from the Mapuche language and shapes daily life in the surrounding valleys, where fruit farming and fishing have been central to the local economy for generations.
The area around the river is accessible for hiking, fishing, and water sports, especially during summer months when weather is more stable. Visitors should expect mountainous terrain where roads are often narrow and winding.
A specialized facility for producing heavy water was built in the 1980s near a town on its banks and remains a technical installation of continental significance. This plant uses the river's hydroelectric power for its highly specialized production process.
