Global Discharge Stations
Global Runoff Data Centre (GRDC). Daily and monthly river discharge from more than 10,000 stations.
The international archive of river discharge, operating under the World Meteorological Organization and collecting data from national hydrological services. It is the standard reference for calibrating and evaluating global hydrological models. The gauge points on this map come from GSIM, which includes most GRDC stations.
