Kukan

The Kukan is a tributary of the Urmi in the forested country north of the Amur. It joins the Urmi from the left, bringing the waters of numerous smaller streams to a river that later meets the Kur to form the Tunguska. Grayling and lenok live in the Kukan. The Urmi valley changes from mountain river and rapids in its upper reaches to open woodland and sphagnum marshes farther downstream.
