Snapshot stats exclude seasonal streams (ie, those which are normally completely dry for at least part of the year), tidal locations and locations where insufficient recent data is available.

River and sea levels are checked regularly by a network of monitoring stations operated by the Environment Agency, Natural Resources Wales and the Scottish Environmental Protection Agency. Flood warnings and flood alerts are published whenever flooding is expected. The Flood Forecasting Centre, a collaboration between the Environment Agency and the Met Office, provides a detailed five day flood forecast for England and Wales.

RiverLevels.UK is an independent website which draws together data from all of these sources to provide a unified river levels and flood warnings map as well as detailed information for each river level monitoring station and flood warning area.
