Lake Toba Physical Description
The astonishing Lake Toba possesses an elongated shape, having a length more than triple that of its average width.
This beautiful body of water measures roughly 62 mi (100 km) in length, and averages a width of 19 mi (30 km).
While water levels naturally vary, this marvel of Nature also has a maximum depth of an astonishing 1,657 ft (505 m).
In addition, Lake Toba also sits at a rather remarkable altitude. The average surface elevation measures 2,953 ft (900 m).
It also has a total surface area of an impressive 440 sq mi (1,130 sq km), and a water volume of 58 cu mi (240 cu km).
Lake Toba Location, Flora, Fauna, and People
The rather stunning Lake Toba formed in Indonesia, in Asia. There, this magnificent wonder of Nature sits on the island of Sumatra.
The gorgeous countryside surrounding the lake has a rather dense covering of tropical rainforest and pine forests.
This beautiful lake itself also primarily serves as home to several types of phytoplankton and related species.
Several varieties of fish do inhabit the lake, but the rather nutrient-poor water only supports a limited number of individuals.
Sadly, rapidly rising pollution levels in the lake now threaten most if not all of the native fish species, as well as a few introduced types.
A small, but sadly shrinking population of indigenous people, known as the Batak, still inhabit the region surrounding the lake.
