SAGE Global River Discharge Database
Compilation of monthly mean river discharge for 3,681 stations worldwide (records from 3 to 100+ years), maintained by the University of Wisconsin-Madison Center for Sustainability and the Global Environment (SAGE). Searchable by country, river or station; exports as tab-delimited files.

What you can do with it
Typical work that data of this type supports.
- 01
Design flows
Estimate 1-in-50 and 1-in-100 year floods for bridges, culverts and spillways.
Because it has: monthly discharge
- 02
Low flows
Set environmental flows and check what is left in the river in a dry year.
- 03
Model calibration
Calibrate and test catchment models against observed flow.
Where AI adds value
Ideas for machine learning and AI agents built on this kind of data.
- 01
Flow forecasting
Train LSTM-style models on past records to forecast river levels and flow days ahead.
- 02
Ungauged basins
Combine with catchment data to estimate flow where there is no gauge.
- 03
Automatic QC
Flag gauge errors, shifts and gaps before they reach a report.
