Environment Agency real-time flood-monitoring API

Environment Agency real-time flood-monitoring API

Keyless Environment Agency API for England covering flood warnings and flood alerts, the flood areas they apply to, the monitoring stations behind them, and water level, flow and rainfall readings. Responses are available as JSON, CSV, RDF, Turtle and HTML.

Coverage

England. The reference page says "Water levels and flows are regularly monitored, usually every 15 minutes." but that "Transfer of data is typically once or twice per day, but usually increases during times of heightened flood risk." Readings are also archived: "The measurement readings are archived daily as dump files in CSV format." The checked response's meta reported version 0.9 and "Status: Beta service". History start and delay: Not stated.

Verdict

A keyless Open Government Licence feed for English flood warnings and near real-time river, tidal and rainfall readings. The reference page says: "These APIs are provided as open data under the Open Government Licence with no requirement for registration. If you make use of this data please acknowledge this with the following attribution statement:" and gives the statement "this uses Environment Agency flood and river level data from the real-time data API (Beta)". Treat it as a beta, not a safety system: the checked response's meta says "Status: Beta service" and the page warns "While they are intended to be stable and robust the open data APIs do not offer a guarantee of service level and should not be relied upon for safety critical applications." No numeric rate limit is stated; the page's crawling note says "The efficient way to do this is to issue a single call every 15 mins". Signal Lab links only.
