Inventory of reservoirs amounting to 90% of total UK storage
This dataset is an inventory of reservoir details for the UK. It provides information, including reservoir location, type (impounding or non-impounding), use (water resources, hydro-electric, ecological, flood storage, canal), capacity, planning date, construction date, catchment National River Flow Archive (NRFA) gauge references and membership of a reservoir group, based on current usage within the CEH Monthly Hydrological Summary (https://nrfa.ceh.ac.uk/monthly-hydrological-summary-uk).

Limitations
- Constraints docs-verified
- Covers 273 reservoirs (about 90% of UK reservoir storage), not all reservoirs · Reservoirs below 1,600 Ml are included only where they belong to reservoir groups with historic storage data · Temporal extent ends 2001-12-31 · Source data quality varies and is flagged per record
