The Río Grande system includes the main river channel, major tributaries, spawning streams, and associated lakes. The true right bank of the Chilean portion of the river, along with its tributaries and lakes, is controlled by a large family farming station called Estancia Las Segadas. This property has not established a fishing lodge and has not provided consistent access to guiding operations, meaning this water remains essentially virgin and unfished by visiting anglers. Cameron Lodge sits on the left bank to the north, close to the Chilean-Argentine border, and caters increasingly to local Argentine anglers fishing the border region.
