Tikhvinskaya water system
Yefimovsky, Russia · built 1802
The Tihvinskaya water system was one of the waterways connecting the Volga River with the Baltic Sea, and specifically the Mologa River with Syas River. In terms of the current administrative division of Russia, the waterway belongs to Vologda and Leningrad Oblasts. It was first conceived by Peter the Great, but construction started only in 1802. The Tihvinskaya water system was built for the passage of middle-sized ships. This Tikhvin system functioned until the middle of the 20th century, when shipping along the Svir River and the construction of railways had increased competition which led to its closure.
