This article presents one of the tools developed in Poland within the framework of the IT system for national protection against extreme hazards. The Water Intakes Monitor, created as a part of the project, is a decision support system that aids the protection of water intakes should they be threatened with flooding. The Water Intakes Monitor and the operational map of surface water and groundwater intakes in areas where floods may occur, present the risk of possible water intake inundation and hazards associated with it. The information on the threat is presented as a water intake status determined by a forecast stream bed expressed as a percentage. Additionally, the application allows us to display supplementary information on current and forecasted hydrometeorological situations and combines it with information provided by flood risk maps.
