The (or ) Tuul (Mongolian Туул гол, Tuul gol, in older sources also Tola ) is an approximately 819 km long tributary of the Orkhon River in the central and northern Mongolia ( Asia) and also the third longest river in Mongolia. Its catchment area covers approximately 49,840 km ².


The headwaters of the Tuul, including the Namin Gol arise within the Töw in Khentii Aimag mountains near the lake Hagiin - Har. In local Gorchi - Tereldsch National Park they flow through of glacial glaciers shaped, broad valleys. Your confluence is located at about 1850 m altitude.

After leaving the highland crosses the initially southwestward flowing Tuul, which stretches is divided into several branches and strong meanders, the southern suburbs of the Mongolian capital Ulaanbaatar. Later, he touches the southern edge of the Chustain Nuruu National Park and runs back again in Töw Aimag. Something underneath it he turns predominantly to the northwest and reached the limit for Bulgan aimag, which from then follows his now northward course.

Finally, the Tuul in Selenge aimag near Orchontuul flows to around 780 m in the Orkhon, via the Selenga ( Selenge ) flows into Lake Baikal.

Floating ice, flora and fauna

The Tuul is mostly covered from November to April of ice. It is home to some endangered species of sturgeon. The area of the river is dominated by willow and birch forests.


The lower reaches of the Tuul is very dirty, especially below the central wastewater treatment plant of Ulaanbaatar. The rapidly sedimenting river is also impacted by minerals that are flooded by mining activities in Zaamar sum in Töw Aimag. The increasing population pressure along the river also contributes to stress.
