Curonian Lagoon
Curonian Spit and Lagoon

The Curonian Lagoon (or Bay, Gulf; Russian: , Lithuanian: Kur?i? marios, Polish: Zalew Kuro?ski, German: Kurisches Haff, Latvian: Kur?u joma) is separated from the Baltic Sea by the Curonian Spit. Its surface area is 1,619 square kilometers (625 sq mi).[1] The Neman River (Lithuanian: Nemunas) supplies about 90% of its inflows; its watershed consists of about 100,450 square kilometres in Lithuania and Russia's Kaliningrad Oblast.[2]

Human history

In the 13th century, the area around the lagoon was part of the ancestral lands of the Curonians and Old Prussians. Later it bordered the historical region of Lithuania Minor. At the northern end of the Spit, there is a passage to the Baltic Sea, and the place was chosen by the Teutonic Knights in 1252 to found Memelburg castle and the city of Memel -- officially called Klaip?da in 1923-39, when the Memel Territory was separated from Germany, and again after 1945, when it became part of the Lithuanian SSR.

As the new interwar border, the river that flows into the Curonian Lagoon near Rusn? (German: Ruß) was chosen. The river's lower 120 km in Germany were called die Memel by Germans, while the upper part located in Lithuania was known as Nemunas River. The border also separated the peninsula near the small holiday resort of Nida, Lithuania (German: Nidden); the southern part of the Spit and the Lagoon remained in Germany until 1945.

This border is now the border between Lithuania and Russia, as after World War II, the southern end of the Spit and the German area south of the river -- the part of East Prussia with the city Königsberg in Sambia -- became part an exclave of Russia called 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). 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.

Natural history and ecology

The Lagoon, formed about 7,000 years BCE, is a freshwater lagoon.[3] Water depths average 3.8 meters.[4] It is highly biodiverse, although troubled by water pollution.[3] The presence of algal blooms was confirmed in the 2000s.[4]
