Find a usable river record

Search a river or gauge. Check the available period and units, then export the data or start a study.

No installation or API key for these workflows. Coverage varies by agency. Recorded analyses show their original version and limitations.

What works today

USGS, UK EA, Hub'Eau: daily records where available. The returned period determines which analyses can run.
PEGELONLINE, OPW: the last month only. Taiwan CWA: daily rainfall.
Anywhere on land: ERA5 climate, GloFAS modelled discharge, and the upstream catchment.
The first analysis loads Python here (about 30 MB, once).
