Recorded Flood Extents
Finding out about recorded flooding
We record flooding incidents from rivers, the sea and, in some locations, from surface water and small watercourses. However, this is only in locations where:
- we are aware of flooding
- we had resource to record it
- we have reasonable confidence in the records
View our Check your flood risk tool to see if we have a record of flooding in an area.
Select the 'Recorded flood extents' layer on our Flood Risk Assessment Wales map to view historical flooding on a map, including the date it was recorded.
The meaning of recorded flooding
If an area is recorded as having flooded in the past, it doesn’t mean that:
- flooding will happen in the same way in the future. There may have been changes in the area which affect the pattern of flooding
- properties in that area flooded internally
Similarly, if an area has no recorded flooding, it doesn't mean:
- it has never flooded. There may be no records or unreliable records
- it won't flood in the future
We will continue to update our recorded flooding information as we gather more data. We'll also record new flood incidents, where adequate information is available.
Getting more information about recorded flooding
Local authorities may have more information about flood risk and historic flooding records.
Contact the local authority for any historic flood information for surface water and small watercourses.
