How to read it

The OPW's CFRAM programme mapped flood extents for about 300 communities at significant risk, plus the river network around them. A town that is not listed may simply not have been mapped, so absence here is not a guarantee. The sea is excluded (land is cut to the high-water mark), but rivers and lakes inside the circle count, so towns on the Shannon or a lough read higher. Flood extents show where water could reach in a flood of that probability, ignoring flood defences that may since have been built; check floodinfo.ie for defended areas and individual properties.
