Dulis'ma

The Dulisma flows through the forested uplands between the Lena and Lower Tunguska basins. A tributary of the Poymyga, it runs through hilly larch and pine taiga before its waters reach the Lower Tunguska and ultimately the Yenisei. Its course is about 64 kilometres long. Nearby rivers rise on the broad Siberian plateau, where the divide separates waters flowing towards different great rivers of the north.
