Lauwersmeer ({{IPA|nl|ˌlʌu.ərsˈmeːr}}) 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.{{cite web | url=http://www.lauwersmeer.com/eng/index.html | title=Lauwersmeer | accessdate=August 2, 2012 | archive-url=https://web.archive.org/web/20120709112438/http://www.lauwersmeer.com/eng/index.html | archive-date=July 9, 2012 | url-status=dead }}

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.

History

The Lauwers Sea (in Dutch: Lauwerszee) was formed by a flood in 1280,Buisman, Jan, Duizend jaar weer, wind en water in de Lage Landen (Deel 1: tot 1300), {{ISBN|978-90-5194-075-6}}

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.

The people living in the area resisted and a committee was formed (actiecomité "Lauwerszee"). They collected 135,000 signatures

of people who wanted to close the Lauwers Sea. In Leeuwarden a large gathering was organised to show the government that local people did not agree with the decision. On 10 June 1960 Kabinet-De Quay decided to enclose the Lauwers Sea,

agreeing to share the cost with the Provinces of Groningen and Friesland, which also agreed to maintain the dike upon completion.

The 13-kilometer-long dike has sluices and a canal lock. A new harbour called Lauwersoog was built part-way along the dike. Final enclosure and separation from the Wadden Sea took place on 25 May 1969;

since then it has been called the Lauwersmeer.

New flora and fauna appeared as the Lauwerszee gradually became a freshwater lake, and to protect this new and young nature area, it was decided (12 November 2003) to designate the Lauwersmeer as a national park.

The ferry to Schiermonnikoog that had previously left from Oostmahorn now leaves from Lauwersoog.

There is a lack of agreement about whether to spell the former name as "Lauwersee" or "Lauwerszee". Some older maps show it as "Lauwerzee".
