Uchami

The Uchami flows through the wooded uplands of central Siberia to join the Lower Tunguska. About 466 kilometres long, it gathers tributaries including the Bugarik before reaching the larger river. The Tunguska crosses rocky plateau country on its way to the Yenisei, and the Uchami rapids are among the obstacles along its course. Long winter ice and the powerful spring rise govern the seasonal character of these northern waters.
