The Whites ' bridgehead south of the River Vuoksi at Antrea on the Karelian Isthmus was a constant problem to the Reds, as it threatened the railway connection Viipuri-Petrograd.

Around 5, 000 BP the waters of the Saimaa Lake penetrated Salpausselkä and formed a new outlet, River Vuoksi, entering Lake Ladoga in the northwestern corner and raising its level by 1 – 2 m.

Due to land uplift, around 5000 BP the River Vuoksi started emptying into Lake Ladoga as a new outlet of Lake Saimaa.

The Taipaleenjoki started draining Suvanto and decreased its level by 7 m. Originally waters of Lake Suvanto flowed into the Vuoksi River through a waterway at Kiviniemi ( now Losevo ), but as a result of the change, the waterway dried out.

Since 1857 Suvanto and the Taipaleenjoki have constituted the southern armlet of the Vuoksi River, which has decreased the level of the original northern armlet emptying into Ladoga near Kexholm ( now Priozersk ) by 4 m, isolating it as a separate river basin.

A few treasures of silver adornments and medieval Arabian and Western European coins have also been found, as the isthmus laid on the Volga trade route ( at that time, the Vuoksi River had a distributary emptying into the Bay of Vyborg ).

In the Battle of Tali-Ihantala, 25 June – 9 July, the Finns concentrated their military strength and brought the offensive to a halt at the River Vuoksi, in the northwesternmost part of the isthmus, at the closest point only 40 kilometres from the border of 1940.

In the course of the last 50 years, this amorphous group of settlements has grown into a modern industrial town dominated by Lake Saimaa, the Vuoksi River and the border.

The Vuoksi River flows from Saimaa to Lake Ladoga.

* Finland had to cede 1 / 3 of her built hydroelectric power, mainly in the form of hydroelectric power plants in River Vuoksi, which was badly needed in Leningrad where the industry suffered a 20 % shortage of electricity.

The lakes of the eastern parts of the town belong to the water system of River Vuoksi.

The line ran from the coast of the Gulf of Finland in the west, through Summa to the Vuoksi River and ended at Taipale in the east.

Priozersk (, before 1948: ; ) is a town in Leningrad Oblast, Russia, located at the northwestern shore of Lake Ladoga, at the estuary of the northern armlet of the Vuoksi River on the Karelian Isthmus.

The Vuoksi River (; ; ) runs in the northernmost part of the Karelian Isthmus from Lake Saimaa in southeastern Finland to Lake Ladoga in northwestern Russia.

A project is currently being discussed in Russia to destroy the rapids at Losevo and turn the River Burnaya, Lake Sukhodolskoye and lower portions of Vuoksi into a navigable canal, which would connect Lake Ladoga to the Gulf of Finland and allow oil tankers to bypass River Neva and the city of Saint Petersburg.

Ladoga level gradually sank as the River Neva had originated around 3100 – 2400 BP, draining its waters into the gulf of Finland, but Vuoksi still had a significant direct outflow connection to the Bay of Vyborg, possibly as late as in the 16th or 17th century AD.

Taipaleenjoki started draining Suvanto and decreased its level by 7 m. Originally waters of Lake Suvanto flowed into Vuoksi River through a waterway at Kiviniemi ( now Losevo ), but as a result of the change, the waterway dried out.

Since 1857 Suvanto and Taipaleenjoki have constituted the southern armlet of Vuoksi River, which has decreased the level of the original northern armlet emptying into Ladoga near Kexholm ( now Priozersk ) by 4 m and become the main stream.

The Vuoksi, largest river, runs southeastwards from Lake Saimaa of Finland to Lake Ladoga, dividing the isthmus into two uneven parts.

The ramparts and towers of the old Korela Fortress are situated on the bank of the Vuoksi, still visible when traveling to the town from Saint Petersburg.

At the Industrial Revolution, power generated from Vuoksi's rapids made the Vuoksi region Finland's industrial center in the late 19th century.

The Vuoksi River flows from lake Saimaa into Lake Ladoga () in Russia.

Lake Ladoga transgressed, flooding lowland lakes and the Vuoksi, and got connected with the sea at Heinjoki ( now Veshchevo ), to the east of present-day Vyborg.

There are many grave pits of Karelians of the 10th-15th centuries with metal and ceramic artifacts along the northern armlet of the Vuoksi, near Lake Sukhodolskoye and in a few other places in Priozersky District.

The old northern distributaries drain only the lower reaches of the Vuoksi basin after 1857 and are not fed by waters of the Lake Saimaa.

leftThe Vuoksi connects Lake Ladoga with central Finland, and was once an important route for trade and communication.

The rapid junction of the Vuoksi and Suvanto / Lake Sukhodolskoye at Losevo is a popular place of kayak, canoe and catamaran competitions.

leftAround 5, 000 BP the waters of the Saimaa Lake penetrated Salpausselkä and formed the river emptying into Lake Ladoga in its northwestern corner and raising the level of the latter by 1 – 2 m. Lake Ladoga transgressed, flooding lowland lakes and Vuoksi, and connected with the Baltic Sea at Heinjoki, to the east of present-day Vyborg.

The Winter War and the resulting Soviet expansion caused considerable bitterness in Finland, which lost its second biggest city, Viipuri, its industrial heartland along the river Vuoksi, the Saimaa canal that connected central Finland to the Gulf of Finland, access to the fishing waters of Lake Ladoga ( Finnish: Laatokka ), and made an eighth of her citizens refugees without chance of return.

Now the Saimaa Canal bypasses the Vuoksi and enters the Gulf of Finland in the Bay of Vyborg near the medieval city of Vyborg.

The most endangered part of that isthmus was to the west, near the Gulf of Finland, the eastern part was better protected by the natural water-ways of Vuoksi, Suvanto and Taipaleenjoki.

Remnants of the Tiuri ( Tiversk ) town ( 10th-15th centuries ) were excavated on a former island in the northern Vuoksi armlet near the Tiuri village ( now Vasilyevo ).

Rapids on the Burnaya River

In 1818 a canal, which was dug to drain spring flood waters from Lake Suvanto ( now Lake Sukhodolskoye, a 40-km long narrow lake in the eastern part of the Isthmus ) into Lake Ladoga, unexpectedly eroded and turned into the Taipaleenjoki ( now Burnaya River ).

In the Middle Ages the river Vuoksa had an outlet there, which however dried up little by little due to post-glacial rebound and was left completely dry in 1857 when the Kiviniemi rapids in Losevo (, ), Karelian isthmus were formed and the Burnaya River became the main outlet of Vuoksa.

to the north of it and since 1857 a new southern branch entering fifty kilometers further southeast as Burnaya River ( Finnish: Taipaleenjoki ), which has become the main stream in terms of water discharge.
