The Vistula Lagoon (Polish: Zalew Wi?lany; Russian: or Kaliningradskiy Zaliv; German: Frisches Haff; Lithuanian: Aistmar?s) is a brackish water lagoon on the Baltic Sea roughly 56 miles (90 km) long, 6 to 15 miles (10 to 19 km) wide, and up to 17 feet (5 m) deep, separated from Gda?sk Bay by the Vistula Spit. It is now known as the Vistula Bay or Vistula Gulf. The modern German name, Frisches Haff, is derived from an earlier form, Friesisches Haff.[1]


The lagoon is a mouth of a few branches of the Vistula River, notably the Nogat, and of the Pregolya River. It is connected to Gda?sk Bay by the Strait of Baltiysk.

The Poland-Russia border runs across the lagoon.

Localities on the lagoon include Kaliningrad, Baltiysk, and Primorsk in Russia's Kaliningrad Oblast and Elbl?g, Tolkmicko, Frombork, Krynica Morska in Poland. The Polish port of Elbl?g used to see a substantial amount of trading traffic on the lagoon, but that has declined owing to the current border situation. Kaliningrad and Baltiysk are currently major seaports on the lagoon.

It is an endangered Important Bird Area of Poland.[2]


The earliest version of the name of Vistula Lagoon has been recorded in historical sources by Wulfstan, an Anglo-Saxon sailor and merchant at the end of the 9th Century as Estmere.[3] It is an Anglo-Saxon translation of Old Prussian name for the lagoon - *A?stinmari (modern Lithuanian - Aistmar?s) derived from (OP - Old Prussian) Aistei - "Aestii" etc. and (OP) *mari - "lagoon (a body of water cut off from a larger body by a reef of sand), fresh water bay".[4] So the oldest known meaning of the name of Vistula Lagoon was "The lagoon or sea of the Aesti". Over three hundred years later, in the first half of the 13th Century, the name of Vistula Lagoon occurs in deeds issued by Teutonic Order in Latin version as Mare Recens (1246 - "mare" - a pool or lake or sea and "recens" - fresh) in contrast to the contemporary name for the Baltic Sea - Mare Salsum (Salty Sea). Then in 1251 we find record about Mare Recens et Neriam (Frisches Haff and Frische Nehrung, now Vistula Spit) and finally in 1288 Recenti Mari Hab (Haff) which as one can see corresponds with later German "Frisches Haff" = "Fresh Lagoon".[5]

Proposed canal

Digging a canal to connect the lagoon with the Baltic Sea is in consideration as a major EU-supported project. The canal, would re-activate the Elbl?g river port. It would also free its dependence on Russia, which occasionally revokes the right of passage for Polish ships through the Strait of Baltiysk as a form of pressure on Polish authorities.[]

In October 2016 details of the project were confirmed by PiS leader, Jaros?aw Kaczy?ski. The 1.3 kilometres (0.81 mi) long, 80 metres wide and 5 metres deep canal shall be completed by 2020 at an estimated cost of PLN 880 million.[] However, major ecological considerations stand in the way. For example, mammal migration along the lagoon could be disrupted. Also, the inflow of brackish waters from the Baltic sea could result in serious unbalancing of the lagoon's freshwater ecosystem.[][dubious ]


East Prussian refugees after crossing the lagoon

From 1772 until 1918, the lagoon was part of the Kingdom of Prussia, which had become part of the German Empire in 1871. Between 1920 and 1946 it was split between Germany and the Free City of Danzig. At present state since 1945 its eastern part belongs to Russia (formerly USSR), Poland has 43.8% of its area at lagoon's western side. The bordering administrative regions is Polish Warmian-Masurian Voivodeship and modern Russian Kaliningrad Oblast.


Curonian-populated area in 1649

While today the Kursenieki, also known as Kur?ininkai are a nearly extinct Baltic ethnic group living along the Curonian Spit, in 1649 Kur?ininkai settlement spanned from Memel (Klaip?da) to Danzig (Gda?sk), including the area around the Vistula Lagoon. The Kur?ininkai were eventually assimilated by the Germans, except along the Curonian Spit where some still live. The Kur?ininkai were considered Latvians until after World War I when Latvia gained independence from the Russian Empire, a consideration based on linguistic arguments. This was the rationale for Latvian claims over the Curonian Spit, Memel, and other territories of East Prussia which would be later dropped.

Historical events related to lagoon

From January until March 1945 throughout the Evacuation of East Prussia, refugees from East Prussia crossed the frozen lagoon on their way to the west after the Red Army had reached the coast of the lagoon near Elbing on January 26. Attacked by Soviet aircraft, thousands of these refugees were killed or fell through the broken ice. [6][7]
