LLANQUIHUE, LAKE

Spanish Lago Llanquihue, lake in Llanquihue and Osorno provincias, Los Lagos regin, southern Chile. The largest and, with neighbouring Todos los Santos, the best known of Chilean lakes, Llanquihue has an area of about 330 square miles (860 square km) and is 22 miles (35 km) long and 25 miles (40 km) wide with depths of 5,000 feet (1,500 m). Its western shores are bordered by farmlands; to the east rise forested Andean foothills. In the distance stand the snowcapped volcanoes Osorno and Calbuco, and beyond them on the Argentine border towers the great, glaciated Mount Tronador (11,660 feet ). The setting of the lake and good fishing have made the lakeside towns, especially Puerto Varas, Llanquihue, and Puerto Octay, popular resorts. Sawmills and a beet-sugar factory are also on its shores. Its outlet is the Maulln River, which flows into the Pacific Ocean.
