All Saints' Flood (1304)

The dating of the disaster to All Saints' Day in 1304, which gave the flood its name, goes back to the Stralsundische Chronik by Johann Berckmann (died 1560).

Some chronicles claim that there was a land connection here, which was destroyed by the All Saints Day flood, so that a new channel, 3 to 4 metres deep, was formed through the so-called Greifswald Bodden threshold and described as a new shipping lane or significant opening.

The Bay of Greifswald was probably still an inland lake and the present-day branch of the River Oder, the Peenestrom, flowed on through the Strelasund and did not discharge into the Baltic until the western end of the sound.

Other consequences of the All Saints Day flood have not been handed down, but it is also possible that it led to breaches to the Baltic Sea at Damerow on Usedom, at the Swine estuary and on the shores of the Prorer Wiek.

For example, Albert Georg Schwartz, wanted to establish the loss of land on Ruden and reported the demise of two villages on the island in a document by Gottlieb Samuel Pristaff, which was revealed as a forgery after 1850.
