Ladoga Canal major canals constructed in Russia. It was one of the projects of Peter the Great, who ordered its construction in 1718. Rapid economic development in Russia required a significant expansion of routes, especially waterways. One part of the Vyshny Volochek waterway (1709) linking the Volga river to the Baltic Sea, passed through Lake Ladoga. The Ladoga section of the route was one of the most difficult and dangerous because the lake is prone to winds and storms which destroyed hundreds of cargo ships. Peter the Great decided to avoid the navigation in the huge and stormy lake by building a
Lake Ladoga concentrated ice of the Fennoscandian Ice Sheet into an ice stream that fed glacier lobes further east. Deglaciation following the Weichselian glaciation took place in the Lake Ladoga basin between 12,500 and 11,500 radiocarbon years BP. Lake Ladoga was initially part of the Baltic Ice Lake (70–80 m. above present sea level), a historical freshwater stage of Baltic Sea. It is possible, though not certain, that Ladoga was isolated from it during regression of the subsequent Yoldia Sea brackish stage (10,200–9,500 BP). The isolation threshold should be at Heinjoki to the east of Vyborg, where the Baltic Sea and Ladoga
