Lauwersmeer (Dutch pronunciation: [ˌlʌuʋərsˈmeːr]) 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.
On the eastern shores of the Lauwersmeer is the Marnewaard, an exercise area of the Royal Netherlands Army. The central and eastern parts of the lake became Lauwersmeer National Park on 12 November 2003.
The Lauwers Sea (in Dutch: Lauwerszee) was formed by a flood in 1280, and named after the river Lauwers, which flows along the border between the provinces of Groningen and Friesland. During the flood the mouth of the river Lauwers disappeared, and its tributaries the Reitdiep, the Dokkumerdiep, and the Ee flowed directly into the new bay. Many plans were made after this disaster to shut it off from the sea but none was ever put into effect. However, parts of it were empoldered piecemeal, slowly reducing it from a large two-forked estuary to the nearly square inlet seen on recent maps.
The first serious plans for draining the Lauwers Sea were from 1849. In the 1930s a commission came up with several plans but all were shelved and were never accomplished. The flood disaster of 1953 and the Christmas flood of 1954 made clear that something had to be done. In 1958 the New Delta Law ordered a reinforcement of the dikes in the north of the Netherlands. At the Lauwers Sea there were two options, to reinforce the existing dikes around the Lauwers Sea (32 km of dikes) or to make a 13 km dam separating the Lauwers Sea and the Wadden Sea. After a study found that the 13 km dike plan was more expensive than the 32 km plan, the government decided on the cheaper option.
