The 416 km long Onega ( Russian Оне́га ) is a river in the northwest of the European part of Russia . It forms the outflow of Latschasees and ends at the port city of Onega in the Onegabucht of the White Sea .
description
The Onega leaves Lake Lacha on its northeastern bank near Kargopol in the southwest of Arkhangelsk Oblast . From there it flows in a wide valley in a predominantly north and north-east direction through the sparsely populated taiga .
At Mirny , it passes the Plesetsk cosmodrome and then turns mainly in north-westerly directions. About 75 km from its mouth, the Onega divides into two arms of the river near Anziferowski Bor , the Great and the Small Onega ( Russian Большая or Малая Онега ). At Ust-Koscha the two arms unite again and form a river island with a diameter of around 20 km . A little later, the Onega reaches the Onega Bay of the White Sea, named after it, below the city of Onega.
Hydrology and use
The Onega shows a nivo-pluvial discharge course with a pronounced maximum discharge at the time of the snowmelt in May and June and a significantly smaller secondary maximum caused by rain in October. The annual minimum runoff falls in March. The Onega begins to freeze over between late October and early December. The ice breaks on average from mid-April to early May, followed by the annual spring flood .
During the ice and flood-free time, the Onega is navigable in sections, the most important port is Onega. In the area of its mouth, the tides of the White Sea are already affecting the Onega, it has a tidal range of 1.5 m.
