 Course of the Wassjugan (Васюган) in the catchment area of the Ob |
||
The 1,082 km long Wassjugan ( Russian Васюган ; also Wasjugan , Vasyugan ) is a left tributary of the Ob in Siberia ( Russia , Asia ).
The Wassjugan rises in the northern part of the Wassjugan Moors (see also Wassjuganje ), the largest moor system in the world with an area of more than 50,000 km² and 14 billion tons of peat in layers up to 10 meters thick, in the West Siberian lowlands near the border between Oblast Tomsk and Oblast Novosibirsk at about 140 m . In the further course it flows strongly meandering in a wide arc through the Oblast Tomsk and finally flows below Kargassok into the Ob. In the lower reaches, in particular, the river forms a multitude of arms, shoals and islands, in the floodplain there are many lakes and oxbow lakes. The actual mouth is that of an arm of the river 11 km below the settlement of Kargassok (45 m above sea level). Near the mouth, the river is approx. 190 m wide and 2.3 m deep; the flow velocity is 0.8 m / s.
The catchment area covers 61,800 km². The mean monthly water flow at Naunak, 63 km from the estuary, is 328 m³ / s (minimum in February: 81.6 m³ / s, maximum in June: 951 m³ / s). According to other sources, the mean discharge at Naunak is 381 m³ / s.
Wassyugan freezes from November to May.
It is navigable to the village of Novy Vasyugan (593 km). In the Wassjugan catchment area, oil and natural gas are produced .
The main tributaries are from the right Nyurolka (Нюролька; 60 km navigable) and Tschischapka (Чижапка), from the left Tschertala (Чертала) and Jagyljacha (Ягылъяха).
