Realtime Flood Data River Flow
This is Approval for Access product AfA305 Realtime Flood Data River Flow. This dataset covers monitoring data that is only updated on our systems on a daily update cycle. This is usually increased during times of flooding etc. Readings are transferred via telemetry to internal and external systems in, or close to real time. This data may be transferred to these systems or users at different intervals varying, for example, from once per day during normal conditions to several times per day durin

What's in it
- Data offered docs-verified
- river flow estimates (typically m³/s) at gauging stations · technical information used for flow calculation at flow gauging stations (e.g. crest tappings at a weir)
- Coverage docs-verified
- England (river gauging stations); Wales sites are included but owned by Natural Resources Wales
- Update frequency docs-verified
- Daily update cycle normally; from once per day in normal conditions to several times per day during a flood event
- Access docs-verified
- Free and open, no public access constraints; licence: UK Open Government Licence (OGL)
Useful for
- Use cases llm-inferred
- Check current river flows at gauges near a site during flood event monitoring · Compare recent gauge flows against historic records as context for an FRA baseline (validate before use) · Gauge-based flow context for drainage or watercourse outfall assessments
- Audience llm-inferred
- flood consultants · hydrologists · drainage engineers
Limitations
- Constraints llm-inferred
- Data is retrieved automatically and is unvalidated · Update frequency varies and is not guaranteed to be real time · England gauging stations only; Wales sites are owned by Natural Resources Wales · Metadata lists update frequency as 'continual', which conflicts with the stated daily update cycle · Metadata reference date is 2014-01-01 and the page was last updated 22 January 2020, so check currency before relying on it
