Real-time and Near-real-time river level data

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 during a flood event. Measurements of the height (m) of water in a river, lake or coastal site taken using automatic field devices, usually every 15 mins. Information is available for 1400 river gauging stations (where flow is also measured) and 1800 river level only monitoring sites throughout England, as well as some reservoirs and coastal sites.
