Full event profile

We have collated approximately 2 billion records from across the UK agencies building up our flood event history. A lot of these are in raw format that we have had to compile and process. With so many values to iterate through, it is certain some are wrong. As such we do not check the underlying data. We do report inconsistencies back to the various agencies when we find them and ask them to fix them.
Values for historical flooding may have been manually input by the relevant governing body (e.g. Environment Agency). Some extreme values may also be above the maximum measurement capability of the station and could also have been edited, by the governing body, to match readings taken manually at the time.
But, if you have spotted something in our archives where you think we have made an error and the the underlying data are correct, please let us know and we can look at getting this fixed.
