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.

Although the canal was one of the largest hydroengineering facilities in 18th-century Europe, it was still too shallow to maintain a considerable traffic. Catherine the Great decided to expand the canal by building another section between the Volkhov and Syas Rivers. This project was implemented between 1765 and 1802 (so-called Syas Canal). The third part of the Ladoga Canal, connecting the Syas and the Svir, was built over the years 1802 to 1810 (so-called Svir Canal). In the course of the 19th century, the Ladoga Canal was used by about 15,000 vessels and 10,000
