Lake Sukhodolskoye Lake Sukhodolskoye Lake Sukhodolskoye (; ) is a narrow 40 km long lake on the Karelian Isthmus located in Priozersky District of Leningrad Oblast, Russia. It is a part of the Vuoksi River basin, constituting its southern armlet, and drained by Burnaya River. Originally waters of Lake Suvanto (Lake Sukhodolskoye) quietly flowed into Vuoksi through a waterway at Kiviniemi. However, in 1818 the channel that had been dug to drain spring flood waters from Suvanto into Lake Ladoga unexpectedly turned into Taipaleenjoki (Burnaya River), which started draining Suvanto and decreased its level by 7 m. The Kiviniemi waterway dried out.
