Where can I find the monthly Hydrological Summary for the UK? 

The latest and previous Hydrological summaries can be found within the NHMP part of the website under Monthly Hydrological Summary for the UK here

Where can I find the FEH data? 

The WINFAP-FEH data files can be now found within About Data in the Peak River Flow Data Section of the website here

Why do the WINFAP-FEH files differ to what is displayed on the website? 

The WINFAP-FEH files are updated when a significant number of changes have been applied to the dataset whereas the website is updated on an ad-hoc basis. In order to be alerted when new files are released you can sign up to our mailing list and follow us on Twitter.
