The Synya flows across the Shuryshkarsky District. It is navigable for 90 kilometres (56 mi), between its mouth in the Ob and Ovgort village.[2]

Course

The Synya is a left tributary of the Ob river. It has its sources at the confluence of the 20 km (12 mi) long Sukhaya Synya and the 87 km (54 mi) long Mokraya Synya, which flow from the eastern slopes of the Polar Urals. The river flows initially southwards, then bends and flows eastwards, within a wide floodplain located at the northwestern end of the West Siberian Plain. Finally it meets the left bank of the Malaya Ob, an arm of the Ob, about 488 km (303 mi) from its mouth.[3][4]

Tributaries

The main tributaries of the Synya are the 178 km (111 mi) long Lesmiyogan (Лесмиёган), the 163 km (101 mi) long Nesyogan (Несъёган) and the 178 km (111 mi) long Bolshoy Tukshin (Большой Тукшин) from the right.[1] The river is fed predominantly by snow and is frozen between October and May.[3][1][2]

Fauna

The main fish species in the river are omul, peled, broad whitefish, sig, and tugun.[2]
