 The Suchona at Totma |

The 558 km long Suchona ( Russian Сухона ) is a river in the Vologda Oblast in northwestern Russia .
The completely navigable river flows from the Kubenasee (Кубенское озеро), which is fed by the Kubena . From there it flows through a swampy lowland mostly in an easterly direction to Veliki Ustyug , where it unites with the Yug coming from the south to form the Northern Dvina . The mean flow rate near the mouth is 456 m³ / s, but can rise to 6520 m³ / s in spring. Due to the strong inflow from the Vologda and Lescha and due to the low gradient on the upper course of the river, the direction of the river may be temporarily reversed towards Lake Kubena. In summer, on the other hand, the flow rate sinks to 17.6 m³ / s, which leads to disruptions in shipping. The Suchona begins to freeze at the end of October or November, and the middle of the river in December. The ice cover does not open until the second half of April or first half of May.
The Suchona and the Northern Dvina are connected to the inner-Russian canal system by a canal that connects the Kubenasee with the Volga-Baltic Sea Canal .
The Suchona, which is longer than the Jug, and the several hundred kilometers long Kubena can be regarded as the actual - merging - source rivers of the Northern Dvina, because they are longer than any other tributary.
