Urmi (river)

The Urmi (Урми) is a river in Khabarovsk Krai of Russia. It is 458 km long and drains a basin of 15000 km2. There are some 1,040 lakes in the Urmi basin; their total surface area is more than 32 km2.

The Urmi merges with the Kur to form the Tunguska, which then falls into the Amur opposite Khabarovsk.

The Urmi's source lies on the southern slopes of the Badzhal Range, from where it begins to flow adjacent to the Bureia Range. The river's lower course passes mostly through the Amur Lowland.

The Urmi depends on rain for most of its water. Its mean rate of flow is 170 m3/s. With the onset of winter in November, the river freezes.

The river is navigable by small craft. One particular stretch of the river, which is 260 km long, is used to float lumber.
