evidence: The Dollart (German name, pronounced [ˈdɔlaʁt]) or Dollard (Dutch name, pronounced [ˈdɔlɑrt]) is a bay in the Wadden Sea between the northern Netherlands and Germany, on the west side of the estuary of the Ems river. Most of it dries at low tide. Many water birds feed there. Gaining from and losing to the sea [edit]According to legend, the Dollart Bay was created by a catastrophic storm surge in 1277,[1] covering the district of Rheiderland and large parts of the Oldambt district. The flood was rumoured to have caused 80,000 deaths.[2] The story, however, is not true and based on legend instead of facts.[3][4][5] The Dollart was created as a slow inundation over many centuries[6] which accumulated in a storm surge in 1509. The 1509 surge extended the Dollart, and flooded 30 more villages,[5] and by 1520 the Dollart had its largest extension. Between the 16th and the 20th centuries, two thirds of the drowned area was reclaimed.
