Lake Ozhogino, Freshwater lake in Sakha Republic, Russia

Lake Ozhogino is a large freshwater body in the Aby Lowland with numerous islands and inlets dotting its surface. The water system connects to the Indigirka River network and plays a central role in the region's water geography.

In 1996 the Sakha Republic government created the Ozhogino Lake resource reserve across the Aby and Allaikhovsky districts, covering 203,756 hectares. It protects the lake's fish, notably the migration of whitefish through the Ozhogino channel during spawning, as well as waterfowl, fur animals and rare plants.

The lake lies in the Aby and Allaikha uluses of Sakha. In 1996 the republican government created the "Lake Ozhogino" resource reserve, covering 203,756 hectares, to protect the lake's fish and the spawning migration of whitefish that enter from the Indigirka through the Ozhogino channel and return to the river. The reserve also shelters waterfowl, fur-bearing animals, wild ungulates and rare birds and plants.

The lake is icebound from late September until early June, so open water is limited to roughly three months. It lies at 31 m above sea level in the Aby Lowland, with Lake Suturuokha a short distance west. The Ozhogino-Syane channel connects it to the Indigirka, and the surrounding tundra has no road access.

The lake drains through the Ozhogin-Syane channel, a left tributary of the Indigirka, not the Ozhogin River as often assumed. Since 1996 the 203,756-hectare Ozhogino Lake resource reserve has protected the spawning migration of whitefish that enter from the Indigirka.
