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 Anglian Water — 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.
Reservoir facts (coordinates, capacity, type, purpose, construction date and downstream gauge) from the UK Reservoir Inventory. Contains data supplied by UK Centre for Ecology & Hydrology (Durant & Counsell, 2018, Open Government Licence v3.0).
