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 Neva to the Svir. The basin of Lake Ladoga includes about 50,000 lakes and 3,500 rivers longer than 10 km. About 85% of the water inflow is due to tributaries, 13% is due to precipitation, and 2% is due to underground waters. Geologically, the Lake Ladoga depression is a graben and syncline structure of Proterozoic age (Precambrian). This "Ladoga–Pasha structure", as it known, hosts Jotnian sediments. During the Pleistocene glaciations the depression was partially stripped of its sedimentary rock fill by glacial overdeepening. During the Last Glacial Maximum, about 17,000 years BP, the lake served likely as a channel that
