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.
Ladoga Canal Chornoe was completed and opened to traffic in 1726. This greatly accelerated work, as the completed section was used to deliver supplies to the construction site. The locks were constructed at Shlisselburg and Novaya Ladoga to maintain the depth needed for navigation. Construction of the canal was completed on October 22, 1730, and in spring 1731 the first boats were able to sail along the canal between the Volkhov River and the Neva River (Ladoga Canal proper). It turned out that the canal had a depth of less than one metre, considerably less than envisioned by Peter I. This was
