Why a single level is not the whole story
A reservoir percentage is a snapshot of one part of a water supply system. Rivers, groundwater, transfers, treatment capacity and demand all matter, so a single figure should not be read as an exact household outlook.
For the practical answer — whether a hosepipe ban affects your address — use the exact-postcode check, which combines the official restriction index with the local supplier position.
