• Discharge data,
• Forecasts and
• Situation reports on the course of flooding.

The HVZ bundles information and makes it accessible to the

The measurement data is updated up to every quarter of an hour, the forecasts are updated every three hours in routine operation and every hour in the event of flooding, and made available via the Internet, the "Meine Pegel" app, teletext, Rundradio and an automatic telephone announcement.

Continuous calculations using water balance models form the basis of the high, medium and low water forecasts for around 100 gauging stations on the Rhine, Neckar, Danube and Main rivers and their most important tributaries.
The transnational forecastingrforecast for Lake Constance is carried out in cooperation with the Swissifederal Office for the Environment and the Office of the Vorarlberg State Government.

In addition, the HVZ calculates flood warning maps for the warning of river sections and catchment areas.
The warnings are issued in five different levels: low, moderate, medium, high and very high flood riskrdanger.
The warning maps are updated hourly and refer to the flood risk for the next two days.

The respective flood hazard map in the area of the displayed water level can be opened via a link.

Municipalities have the option of providing the HVZ with a link to community-specific flood hazards and protective measures.
These are then stored at the respective HVZ gauging stations under the heading Flood hazard information and can thus be made accessible to the general public.
