Real-time Flood Data River Flow

This is Approval for Access product AfA305 Real-time Flood Data River Flow via our API. This dataset covers monitoring data that is only updated on our systems during a routine daily update cycle, some sites will update more frequently as we update the field technology used over the next few years till 2025. During times of flooding, or other water level related incidents our update frequency can be increased if the technology at site allows. Readings are transferred via telemetry to internal and external systems in or close to real-time. This data is transferred to other systems, including the API. Data for some sites in Wales are included in the Open Data feed, but is owned by Natural Resources Wales (NRW). NRW also class the data as Open Data, and you may use it under the same terms as the England data (the standard Open Government Licence, available on The National Archives website). This data is retrieved automatically and is unvalidated. Estimates of flow (typically how many cubic metres per second). Information is available for river gauging stations throughout England. Technical information used for flow calculation at flow gauging stations is also provided. For example, crest tappings at a weir.
