Real-time Flood Data River Levels for England and Wales

1400 river gauging stations and 1800 river level monitoring sites across England and Wales provide water height measurements. The Environment Agency and Natural Resources Wales collect data via automatic field instruments, typically logging values every 15 minutes. During flooding incidents, update frequency can be increased if site technology allows.

Use Cases

• Flood risk modeling based on real-time river level data
• Environmental monitoring dashboards using water height measurements
• Incident response planning based on variable update frequency during flooding events
• Hydrological research using data from 3200 monitoring sites

Strengths

• Covers 1400 river gauging stations and 1800 river level monitoring sites
• Data update frequency can be increased during flooding incidents
• Measurements are typically logged every 15 minutes

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Description metadata is limited; actual data quality requires manual inspection after download
