The flooding North Sea created the islands of Wieringen and Texel. Lake Flevo was once a fresh water lake, but a sea channel opened a connection from the North Sea into the lake through Creil Woods. Lake Flevo began to turn into the salt-water sea known as the Zuiderzee. By around 1248, the transformation of the lake into the Zuiderzee was complete.[1] By around 1248, The Creiler Woods vanished under the waves. The sea area increased inside the Netherlands and large peat areas developed, which were easily washed away.
The flood rendered the settlement of Rotta (the predecessor of Rotterdam) uninhabitable,[2] and marked the beginning of Amsterdam, where the area gained an open connection to the sea, and where a dam was built in the Amstel to protect the land from future floods.[3]
