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.[2] 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).[1] 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.[1]
Flora and Fauna
[edit]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.[3]
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.[4]
Climate
[edit]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.
