St. Peter's flood

St. Peter's flood (Dutch: Sint-Pietersvloed, German: Petriflut) refers to two separate storm tides that struck the coasts of Netherlands and Northern Germany in 1651.

[citation needed] The storm tide on 22 February struck the North Sea coast in Northern Germany, including the German Bight.

[4] The flood even reached the Altes Land, south of the city of Hamburg, leaving the lake of Gutsbrack.

Two gaps struck in the Zeeburgerdijk [nl] left two ponds in what is now the Indische Buurt neighbourhood of eastern Amsterdam.

[6] The storm tide also left a small lake, the Nieuwe Diep (Amsterdam) [nl], which was never filled in and is still in existence.

After the disaster, the dikes were restored and the floodwater was pumped out again and on 15 July 1652, the inhabitants of the Watergraafsmeer paraded through their polder to celebrate that it was dry once again.

In Friesland, the storm tide broke through the dikes surrounding the Dokkumer Grootdiep [nl] (a canal connecting Dokkum to the sea), leaving a small, round pond, the Mallegraafsgat [nl] or Sint Pitersgat, which is still in existence.
