Voikar
The Voikar descends from the eastern side of the Polar Urals to the lower Ob. Near its mouth it spreads into the broad floodplain lake called Voykarsky Sor before joining the Malaya Ob. A settlement called Voikar stood on the river and was mentioned in seventeenth-century geographical descriptions. The river links mountain valleys and forested foothills with the fishing waters of the great Siberian plain.
