Icalma Lake is a lake of glacial origin located in the Andes of the La Araucanía Region of Chile. A hamlet on the southern shore of the lake is also called Icalma. About 3 kilometres (1.9 mi) from the hamlet is Icalma Pass, 1,307 metres (4,288 ft) in elevation and on the border with Argentina. The pass is traversed by a road, unpaved in Chile in 2017 and sometimes impassable during the Southern Hemisphere winter due to heavy snows. Icalma Airport is located 9 kilometres (5.6 mi) northeast of the hamlet.
Icalma Lake is connected to the Laguna Chica de Icalma (Little Lake of Icalma) by a short stream about 300 metres (980 ft) long. The two lakes together have a surface area of 11.7 square kilometres (2,900 acres). Icalma Lake drains northeastwards by way of a 10 kilometres (6.2 mi) long river named Rukanuco. Icalma Lake and nearby Galletué Lake are the sources of the Bio Bio River.
Flora and Fauna
The most abundant species of fish in the lake is the brown trout. The lake also has a population of rainbow trout. Neither species is native to Chile.
The lake and village are in the ecoregion of the Valdivian Temperate Rain Forest. The monkey-puzzle tree (Araucaria araucana) locally called "pehuen" is the most distinctive of the tree species in the forest.
Climate
Under the Köppen climate classification, Icalma has an oceanic climate, designated Csb. Under the Trewartha climate classification the climate is Crlk: mild summers, cool winters, and humid.
