Manso River (Argentina and Chile)


The Manso River is a river of Rio Negro Province of Argentina and Los Lagos Region of Chile, both part of Patagonia. The Manso River is located in the Andes. It follows a winding route through snow-capped mountains and connects many glacial lakes. The Manso flows generally southward until its confluence with the Puelo River in Chile. The river while in Argentina flows through the Nahuel Huapi National Park.
Most of the southern part of Nahuel Huapi is in the drainage basin of the Manso River.

Description

The Manso River arises at elevation of in the small lake fed by the Ventisquero Negro glacier. The river flows about eastward to Mascardi Lake. From Lake Mascardi the river passes through or by a chain of lakes separated by short passages of often turbulent river. The lakes include Las Moscas, Hess, Roca, Franck, Martin, and Steffen. A road runs along the eastern and south shore of Mascardi Lake and continues downstream for another, ending near Lago Hess. The river then runs through a roadless area until reaching the lower end of Lake Steffen, where a road rejoins the river. Lake Steffen is the last lake in the chain and the Manso continues its path through Argentina and into Chile. About after entering Chile the Manso joins the Puelo River.

Recreation

The Manso River is popular for whitewater rafting, especially in its course below Steffen Lake to the border with Chile. The character of the river ranges from "peaceful"—the meaning of the word "manso" in Spanish—to Class IV rapids. Sport fishing for the introduced species of brown, rainbow and brook trout in the river and its lakes is also popular. Many tourist agencies in the city of Bariloche offer rafting and fishing excursions. A portion of the long-distance Huella Andina trail passes near the river and the lakes that dot its course.
