Closing of water barrier

Print Email


Flood hazard

An increased flood hazard because the flood defence does not meet the requirements and/or due to extreme conditions.

The old medieval city wall of Kampen is adapted to stop the water like a stone dyke. Where streets and squares interrupt the historic city wall, the barrier consists of separate elements that quickly need to be closed off when the water level on the IJssel rises.


High Water Brigade

The closing of the Kampen-Midden flood defence is done in collaboration with 200 volunteers that, together, constitute the High Water Brigade. In the event or threat of high water levels in the River IJssel, they close the flood defence.


  • Volunteers help with closing off of the flood defence.
