River/lake flood: 20% annual probability
What this layer shows
Modelled flood hazard, not a live forecast. Recurrence represents estimated annual probability at the source modelling date. River/lake scenarios exclude ice effects. Mapping is geographically incomplete; an empty map does not demonstrate safety. The waterbody class represents existing water. Precision is insufficient for building-specific conclusions. Online maps use publisher depth and protection styling. Downloaded vectors use one colour; inspect feature attributes for depth. National downloads are very large; choose a local area where appropriate.
