Delta Works The Delta Works (Dutch: "Deltawerken" ) is a series of construction projects in the southwest of the Netherlands to protect a large area of land around the Rhine-Meuse-Scheldt delta from the sea.

The aim of the dams, sluices, and storm surge barriers was to shorten the Dutch coastline, thus reducing the number of dikes that had to be raised.
Lauwersmeer Lauwersmeer (] ) is a man-made lake in the north of the Netherlands, on the border of the provinces of Groningen and Friesland. The lake was formed on 23 May 1969, when the dike between the bay called Lauwers Sea and the Wadden Sea was closed. It is noted for birdwatching.
