So you planned to visit Holland. Welcome! You’ve probably made a list of all the places you want to visit. Here I’ll have some useful information you can add to your list: how big is the risk that the area will be flooded and how high will the water level be.

Enter the name of the place you’re visiting or the zip code and returns the maximum water level during a flood. The site also returns the risk of flooding and tips what to do  when the water comes. But don’t worry! The risk applies to people who live in the city or village you entered.

Leidsche Rijn, near Utrecht

I live in Leidsche Rijn, a suburb of the city Utrecht. There is a probability of less than 1% that we’ll be victims of a flood in this area in our lifetime, with an estimated maximum water level of 1 meter.


For people who live in Dordrecht, the situation is worse. The probability of a flood is more than 10% for them and the estimated maximum water level is 4.5 meter.
