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.
Finnish Ladoga Naval Detachment group was the icebreaker "Aallokas", whose commander Captain-Lieutenant Asikainen also commanded the gunboats. There were no major naval battles in the open waters of Lake Ladoga during 1939 - 1940, so the fleet units were tasked with fire support against the attacking Red Army, and spreading mines along the coastal areas. By January 1940 the ice became so thick that only "Aallokas" could be used, and she was damaged in an attack by Soviet aircraft on February 2. After the peace on March 13 the Finnish vessels had to be left at Ladoga, which had become a Soviet lake. Some
