Бокситогорский район
A considerable part of the Tikhvinskaya water system, one of the waterways constructed in the early 19th century to connect the basins of the Volga and Neva Rivers, lies in Boksitogorsky District. The waterway runs from the Syas upstream the Tikhvinka River. Lake Yelgino is connected by the Tikhvin Canal, with the upper course of the Volchina River. The waterway then follows downstream the Gorun River, the Chagodoshcha River, and the Mologa River. Currently, it is not used for any commercial navigation.
