Lake Kovzhskoye
Lake Kovzhskoye lies amid the forests north of White Lake and gives rise to the Kovzha River. The river flows south towards White Lake, while the nearby watershed leads towards the Vytegra and Lake Onega. Travellers once used a portage between these river systems, carrying boats and goods overland. In the early nineteenth century the Mariinsky waterway joined the two routes by canal, changing the lake's natural water regime.
