Recorded Flood Extents

Recorded Flood Extents shows areas that have been recorded to have flooded in the past from rivers, the sea or surface water. The records come from a number of evidence sources including Natural Resources Wales, its predecessors or other Risk Management Authorities. It is possible that the pattern of flooding in an area may have changed and would now flood under different circumstances. In addition, the absence of a recorded flood extent does not mean that the area has never flooded, only that we do not currently have records of flooding in this area.

Lineage

The data is updated every three months, but may not change quarter to quarter if there have not been any significant flood events in the preceding period. Recorded Flood Extents are digitised in ArcGIS from a number of sources including surveyed flood events. Please note that this map shows flooding to the land and does not necessarily indicate that properties within the Historic Flood Map were flooded internally. This dataset was update in May 2017 to include attribution data on the flood events. This was previously made available in the product \Recorded Flood Outline\" which is no longer updated and no longer available."
