European Water Archive (EWA) of EURO-FRIEND-Water

... has been a central feature of the EURO-FRIEND-Water Programme.

Since its inception in 1985 the European Water Archive (EWA) collected long-term daily flow data and catchment information from more than 4000 river gauging stations in 30 countries. In October 2014 the EURO-FRIEND-Water meeting in Montpellier concluded that the EWA will no longer be updated and will be "frozen at its current state".

The Global Runoff Data Centre (GRDC), Federal Institute of Hydrology, Koblenz, Germany, hosts the European Water Archive since 2004.

The archived data remain unchanged and will be provided by the GRDC on special request by writing to

Please use the GRDC station catalogue for up-to-date data of stations in Europe incl. those which have been transferred to the GRDC database.
