How to read the data

RiverData does not present every value as equally certain. Sensor measurements, third-party model output, calculations made here and fixed reference figures are labelled separately. The source registry names the publisher, dataset, update cadence, formula and known caveat behind each displayed field.

What has - and has not - been reviewed

The provenance registry was last checked internally against the serving endpoints on . Automated tests reject missing source links, retired endpoints and incomplete data classifications. RiverData has not yet received an independent scientific or editorial review. We say that plainly because internal checks are not a substitute for external scrutiny.
