The Ibáñez River is a watercourse that flows in the Aysén Region of General Carlos Ibáñez del Campo and is one of the most important sources of the Baker River basin to which it joins through Lake General Carrera.
The river is born in a snowdrift that detaches to the SE from the glaciers surrounding the Hudson Volcano, whose waters are affected by the eruptions of the Andean heart. In the Andean heart, it limits to the north with the Aysén River basin, in particular with the basin. of the Huemules (Simpson) River (which will give life to the Simpson River further north).
It initially runs in a SE direction for 30 km, then east for another 30 km to change its lower course again in a SE direction for 28 km, thus achieving a total length of 88 km.[2]: 559
Its drainage area limits to the north with those of the Blanco River (West), to the south with those of the Murta River and its main tributary is the Manso estuary, an outfall of Lake Lapparent and other minor ones.
On the left side it receives the minor courses Riacillos, Nieve, Parado. In the lower course, it receives no less than six streams per band, some of them with names: Estero del Bosque, Estero Limpio, Chorrillo, Peñascos. These on their left flank. On the right, the Claro estuary.
It flows into Bahía Ibáñez of Lake General Carrera, where the lake port and the town of Puerto Ingeniero Ibáñez are located.
