Тихвинская водная система

Introduction.

One of the important and little-known engineering architecture of the Leningrad Region is Tihvinskaya water system. It was conceived by Peter the Great and required for its establishment many decades. Tihvinskaya water system was built for the passage of srednemernyh courts in the early 19 th century and functioned until the mid 20 th century. Establishment of railways and the movement of ships along the river Svir amounted competition, which led to the closure of the Tikhvin system.

Geography

Tihvinskaya water system started at the Rybinsk wharf on the river Volga. The system was 32 miles along the Volga, then 175 miles on Mologa. From Mologi waterway turned aside at Chagodoshcha and gone179 miles along the rivers Chagodoshcha, Gorun and lakes Chagodoshcha. After 33 miles the river Somin, lakes and river Somin Wołczyn. Between the upper and Lake Wołczyn Elgin passed Tikhvinskij channel for 6 miles 325 yards. Then the path ran on the lake and river Tikhvinka Elgin (159 miles 457 yards), then 88 miles the river Syasyu. Then the route goes through: 10 miles and 104 miles Syaskim Ladoga. And finally 22 miles of Lake Ladoga and the Neva River 58 miles away. Tihvinskaya system ends at the pier near the Alexander Nevsky Lavra in St. Petersburg. Its length is 847 miles 385 yards - 902 km.

History

In the 18 century building Tikhvinskaia water system rise several times on the agenda, but each time was delayed due to lack of money in the treasury. In the summer of 1797 because of the severe drought of the court could not pass through Vyshnevolockij system. Again, the question arose about the construction of the Tikhvin system. January 1, 1802 Alexander I approved a draft of the water system General Devolant that would have built 17 locks and 10 of the sluice, and the channel between the lakes and the Swan Krupin.

The current state

Today, all the gates are destroyed, most survivors - Tikhvinsky, Kursk and Yaroslavl gateways. The water level in Tikhvinka fell more than 5 meters. Tihvinskaya water system fell into decline. Tikhvinka heavily polluted with household waste. In extreme distress were numerous monuments of architecture, located on the banks of the river Tikhvinka and its tributaries.
