Amsterdam: E Maaskamp, 1825. Map of the area around the Zuiderzee and in the north of the Netherlands affected by the flooding in February 1825. The flooded areas are colored blue. Part of a series of five maps of the affected areas.
This map is based on Maaskamp's map of Les Provinces du Nord found in his Pocket atlas of the Kingdom of the Netherlands published in 1821. There is an additional title printed and the flooded areas are additionally coloured. Overall in very good condition, with some darkening around the folds. The blue indicating the flooded areas is somewhat faded, but still visible.

The February flood of 1825, also known in Germany as the Great Hallig Flood (Große Halligflut), was a devastating flood that occurred from 3 to 5 February 1825 on the North Sea coast, in which about 800 people were drowned.
In the Netherlands, the February flood was the worst natural disaster of the 19th century. Most of the dead and the worst damage was in Groningen, Friesland and Overijssel. The reaction at national level was quite similar to that during the flood of 1953; yet the event was surprisingly quickly forgotten once the damage had been repaired and had no political or engineering consequences. It needed the disaster of 1953 in order for a delta law to be passed and to improve coastal protection significantly.
