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.
Lake Sevan cultural monument is the Sevanavank monastery located on the peninsula, which was until the mid-20th century an island. Another prominent monastery at the western shore is Hayravank, and further south, in the village of Noratus, is a field of "khachkars", a cemetery with about 900 "khachkars" of different styles. Additional "khachkars" are found at Nerkin Getashen on the south coast. Sevan trout ("Salmo ischchan") is an endemic species of the lake, but it is endangered as some competitors were introduced into the lake, including common whitefish ("Coregonus lavaretus") from Lake Ladoga, goldfish ("Carrasius auratus"), and crayfish ("Astacus leptodactylus").
