You can contact the administrator of this website by email at 'info{at}riverlevels.uk' (making the obvious substitution to turn that into a valid email address).
Important! Before you email us asking if we've got river level data that goes back further than the downloadable csv files, the answer is that we don't. All the data we do have is in those files. So there's no point asking us for older data.
If you want older data, you may be able to get it from the underlying data sources. See the Credits and Copyright page for more details and links to data suppliers.
