Amsterdam waterlevel during the flood in 1775

The Amsterdam City Archives provide the inventory of the archive of the Amsterdam City Water Office (Stadswaterkantoor). This archive offers water level registers from 1601 up to 1841. This dataset provides the transcribed and transformed (from 'duim' into meters) measurements from the 9th of November until the 21st of November 1775. The measurements were taken in the IJ and in the city. The specific reason for the chosen time period is the flood on the 14th and 15th of November 1775. The city centre was spared from disaster (due to effective sluice management) but streets, houses and cellars near the IJ, e.g. in Kattenburg, Wittenburg and Oostenburg, were flooded. The dataset shows the 'normal' water level up to 7 days before and after the flood, which amplifies the extreme water levels during the flood. Thanks to Kees Hogenes for helping out.
