Lake Ilmen
The Volkhov flows out of Lake Ilmen north into Lake Ladoga, the largest lake in Europe. It is the second largest tributary of Lake Ladoga. It is navigable over its whole length. Discharge is highly variable depending primarily on the level of Lake Ilmen. The Volkhov is reported to reverse the direction of its flow in its upper section in exceptional circumstances. The river freezes up in late November, and breaks up in early April.
