'the lake of the Tyolyos [ru]'; Altay: Алтын Кӧл, romanized: Altın Köl, lit.

Therein studies are performed of the insect-eaters and rodents of Altai Republic, helminthofauna of vertebrates in biocenoses of taiga, ichthyocenose and animal plankton of Lake Teletskoye.

Ecologists, geologists, and archeologists from Institute of Water and Ecological Problems (Russian: Институт водных и экологических проблем СО РАН) the Siberian Division of the Russian Academy of Sciences from the Institute of Water and Ecological Problems spend many years working here to study the lake and surrounding area.

Geomorphologists and geologists scrutinize geological structure of Lake Teletskoye, its paleogeography, age, and origin.

The investigators carried out large-scale exploration routes on vast territories near watersheds of the upper reaches of all the rivers in the northern and western parts of the Teletskoye Lake basin.

This important fact leads to an unavoidable conclusion about the youth of the Teletskoje Lake depression – the post-glacial age of “the last cutting” during the pre-glacial (Late Quaternary) peneplain.
