During the sixteenth century, Reimerswaal became increasingly vulnerable to flooding. The ground around Reimerswaal was suffering severe subsidence due to salt extraction. On St Felix Day (Saturday 5 November 1530) the area suffered a huge storm surge. This day would later be known as ‘quade saterdach’ (Bad Saturday). The city itself was not wiped out by the St. Felix flood, but a large part of the surrounding countryside was. Plans were drawn up to restore the dikes in the area to the east of Reimerswaal. But a new flood in 1532 put an end to these hopes. A new major storm surge cut the city off from the rest of Zuid-Beveland for good.
