Vistula Lagoon 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. 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.
Lagoon of Patok Lagoon of Patok The Lagoon of Patok () is a lagoon of the Adriatic Sea on the Mediterranean Sea in the central coast of Albania. Created during the Holocene period, this area was characterized by a geo-morphologic dynamism. Its development spanned four phases, which correspond to the formation of four lagoons, separated by littoral cordons. The fourth lagoon is the current one. A fifth lagoon (the current outer lagoon) is in an active formation process, also influenced by a rapid development of the littoral cordon in the western part. The whole area is flat and characterized by an intensive tectonic
