England River and Tide Readings (Latest Level and Flow at an Environment Agency Gauge)

eafloods/station-readings

The most recent readings at one Environment Agency river or tide gauge in England, newest first, from its real-time flood-monitoring API (Beta). Each reading gives the time (UTC), the value, and the measure it belongs to inline: water level or flow, its unit (for example mASD or mAOD for level, m3/s for flow), the reading interval, and the station name. Gauges usually record every 15 minutes, but the Agency receives the data in batches, so the newest reading can be hours old. Get the stationReference from England River and Tide Monitoring Stations. A Beta service with no service-level guarantee: not for safety-critical decisions, and no replacement for the Environment Agency's own flood warnings. Attribution: this uses Environment Agency flood and river level data from the real-time data API (Beta). Contains public sector information licensed under the Open Government Licence v3.0.
