Arangatuy

Lake Arangatuy is a protected body of water in the Barguzinsky District surrounded by dense forests and steep mountains that rise between 2000 and 2700 meters (6500 to 8900 feet). The Burtuy River flows into the lake, creating an interconnected water system that sustains multiple fish species in its waters.

The Barguzinsky District where the lake sits was established in 1923 during administrative reorganization of the Buryatia region. This formal foundation shaped how the territory has been managed and protected ever since.

The lake holds deep significance for local Buryat communities who depend on its waters for traditional fishing practices that have persisted through generations. This connection to the water shapes the cultural identity and livelihood of people in the region.

Access to Lake Arangatuy goes through Ust-Barguzin village, where summer accommodation ranges from holiday camps to private hotels near the water. The best visiting season is June through September when weather conditions are milder and mountain roads are more passable.

The lake supports cisco, grayling, and whitefish species that have adapted to its cold waters and mountainous setting in ways specific to this region. These fish populations represent important examples of cold-water ecology in Siberian lakes.
