Largest Lakes in Chile

General Carrera Lake (Chilean part, officially renamed in 1959) or Lake Buenos Aires (Argentine part) is a deep lake located in Patagonia and shared by Argentina and Chile. Both names are internationally accepted, while the autochthonous name of the lake is Chelenko, which means "stormy waters" in Aonikenk. Another historical name is Coluguape from Mapuche, a derivative of this name is applied to Colhué Huapí Lake after Argentine explorer Francisco Moreno reached this lake in 1876 conflating it with Coluguape (General Carrera Lake).

The lake is of glacial origin and is surrounded by the Andes mountain range. The lake drains to the Pacific Ocean on the west through the Baker River. During the last glaciation the lake drained to the Atlantic through Deseado River.

The weather in this area of Chile and Argentina is generally cold and humid. But the lake itself has a sunny microclimate, a weather pattern enjoyed by the few settlements along the lake, such as Puerto Guadal, Fachinal, Mallín Grande, Puerto Murta, Puerto Río Tranquilo, Puerto Sánchez, Puerto Ingeniero Ibáñez and Chile Chico in Chile, and Los Antiguos and Perito Moreno in Argentina.

Viedma Lake (Spanish: Lago Viedma, Spanish pronunciation: [laɣo ˈβjeðma]) is a Patagonian lake in the province of Santa Cruz, Argentina, situated near its border with Chile. Measuring approximately 50 miles (80 km) in length, it is a major elongated trough lake formed from melting glacial ice. Viedma Lake is the second largest perennial lake located entirely within Argentina.

The name of the lake comes from the Spanish explorer Antonio de Viedma, who in 1783 became the first European to reach its shores.

The town of El Chaltén and the Andes peaks Cerro Torre and Fitz-Roy lie in the proximity of the lake.

Lake Viedma is fed primarily by the Viedma Glacier at its western end. The Viedma Glacier measures 3 miles (5 kilometers) wide at its terminus at Lake Viedma. The brown landscape is a result of ice scouring, which left virtually no vegetation on the steep-walled valleys.

Water from Lake Viedma flows into Lake Argentino through the La Leona River, and eventually from there into the Atlantic Ocean through the Santa Cruz River.

Llanquihue Lake is the second-largest lake in Chile with an area of about 871 km2 (336 sq mi), after Lake General Carrera which is shared with Argentina. It is situated in the southern Los Lagos Region in the Llanquihue and Osorno provinces. The lake's fan-like form was created by successive piedmont glaciers during the Quaternary glaciations. The last glacial period is called Llanquihue glaciation in Chile after the terminal moraine systems around the lake.

Some historians consider Llanquihue Lake to have been within the range of ancient Chono nomadism.

Llanquihue Lake is located in southern Chile a territory of northern Patagonia in the Los Lagos Region. The lake's views of Volcán Osorno make the surrounding cities such as Puerto Varas tourism hotspots.
