Where this comes from. Reservoir data © the UK water companies, from their published reservoir-level reports and the Stream water-industry open data portal (CC BY 4.0). Thames Water London history via the London Datastore (Open Government Licence v2). Figures are exactly as published by United Utilities — reporting day and
rounding are theirs, so "as of" dates differ row to row. Levels older than 21 days are marked
"last reported" rather than treated as current.
