Data access

Use the machine-readable JSON record or the flattened CSV download or the compact Markdown version.

Methodology

Real-time level gauges within 20km of central London from the Environment Agency flood-monitoring API. Each gauge is compared with its own previous reading to give a direction. Levels are relative to each station's own datum, so they are comparable over time at one gauge rather than between gauges.
