With the MijnHoogwaterstanden Basis app you can receive information and automatic alarms about current and expected water levels for various locations in the Netherlands. We use measurements and water level forecasts as drawn up by Rijkswaterstaat and made available via an open data portal.

Download the MijnHoogwaterstanden Pro app if you want to set personal alarm levels for one or more locations.
