The lagoon is a mouth of a few branches of the Vistula River, notably Nogat and Szkarpawa, and of the Pregolya River.
The lagoon is split between Poland (including the localities of Elbląg, Tolkmicko, Frombork, and Krynica Morska) and Russia's Kaliningrad Oblast (including the localities of Kaliningrad, Baltiysk, and Primorsk). Before 2022, the only water route from the lagoon out to the Gdańsk Bay was the Strait of Baltiysk, in Russia's portion of the lagoon. The Polish port of Elbląg used to see a substantial amount of trading traffic on the lagoon, but that declined due to international tensions and silting. Between 2019 and 2022, Poland built the Vistula Spit canal in their own portion of the lagoon, to create another water route out of the lagoon. Kaliningrad and Baltiysk are currently major seaports on the lagoon.

The earliest version of the name of the Vistula Lagoon has been recorded in historical sources by Wulfstan of Hedeby at the end of the 9th Century as Estmere.[3] It is an Anglo-Saxon rendition of the Old PrussianAīstinmari,[citation needed] which was the name for the lagoon. The name was the fusion of two Old Prussian words:
*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 the Vistula Lagoon was "The lagoon or sea of the Aesti". The Old Prussian name is still used in Modern Lithuanian as Aistmarės, which preserves the original meaning.
Over three hundred years later, in the first half of the 13th Century, the name of the Vistula Lagoon occurs in deeds issued by the Teutonic Order in Latin as Mare Recens (1246 - "mare" - a pool or lake or sea and "recens" - fresh) in contrast to the contemporaneous name for the Baltic Sea - Mare Salsum (Salty Sea). Then in 1251 there is a reference to Mare Recens et Neriam and finally in 1288 Recenti Mari Hab, which evidently corresponds with the German "Frisches Haff".[5] The modern German name, Frisches Haff, is derived from an earlier form, Friesisches Haff.[6]
The nearly extinct ethnic group or Kursenieki lived on the Vistula Spit, by the lagoon.
Historical events related to the lagoon
From January until March 1945, throughout the evacuation of East Prussia, refugees from East Prussia crossed the frozen lagoon on their way west after the Red Army 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.[9][10]
