Lauwers The Lauwers () is a river in the Netherlands. It forms part of the border between the provinces of Friesland and Groningen. From the 730s to Widukind's defeat in 785, it was part of the border of the Frankish Empire. The former Lauwerszee and ...

. 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
