SEPA Time Series Data Service (Scotland river level and flow API)
Scottish Environment Protection Agency programmatic time-series API serving rainfall, groundwater level, river level (stage), river flow (discharge), tidal level and derived statistics (daily means/min/max) from its hydrometric network of ~392 sites. Documented self-service REST API with station metadata and observations.

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: river flow
- 02
Low flows
Set environmental flows and check what is left in the river in a dry year.
- 03
Design storms
Build rainfall intensity-duration-frequency curves for drainage design.
Because it has: rainfall
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
Downscaling
Turn coarse rainfall grids into field or ward scale estimates.
