The Khoton and Khurgan lakes are second largest and clearest of all lakes in Mongolia. The average depth is 26 m, the maximum depth is approximately 58 metres.
The landscape around the lakes is stunning: with forests and the snow-capped Altai Mountains. Khoton and Khurgan lakes are home to the grayling (thymallus arcticus) and the lenok (brachymystax lenok). The lakes are located in an intermontane tectonic depression in the northern portion of the Mongolian Altai Region. The lakes themselves, as well as the mountain rivers which feed the lakes, offer excellent sport fishing in a rugged and virtually unpopulated area.
Surface area is 50.1 km2; the average depth is 26.6 m; the maximum depth is approximately 58 m. Khoton lake has one Iceland which is covered by woods. The system of Khoton and Khurgan lakes, connected by a wide channel, is the source of the Hovd river which drains the whole Mongolian Altai. Lake Khoton was formed by glacial blockages. Khurgan nuur is the lowest point of Altai Tavan Bogd National park.
