Report Past Flood Event
The National Flood Data Archive, which provides all the information for Past Flood Event records, is continually being updated and added to by the OPW. Information on new and past flood events can be, and is, submitted from a variety of sources (government, private and individuals) for inclusion as it becomes available. All information is checked and classified first, then approved before it appears on the website.
Past Flood Event information is currently accessible for events which occurred pre Autumn 2014. Information on floods that have occurred since then will be uploaded to the website in due course.
We welcome information on recent or past flood events including supporting documentation, which can be submitted by using the
Past Flood Event Short Form 
The OPW has prepared a guide to flood data collection,
Flood Data Collector's Handbook, to set standards for flood event data collection with the
objective that flood event data is collected effectively in a safe environment. The primary audience of the handbook is Local Authority staff and consulting engineers who
collect flood event data as part of their professional duties and responsibilities. While the guide may also be of interest to members of the public, the OPW does not advise
or encourage members of the public to visit flood event locations for the purpose of recording flood event data.
