The autumn deluge has seen reservoir levels rise rapidly, according to water companies, but some parts of the UK remain under a hosepipe ban.In July and August, reservoir levels across the north of England dropped dramatically following months of record-low rainfall, with some reaching unprecedented levels, exposing lost villages and drowned bridges.Yorkshire Water said the county had the same amount of rainfall in September and October as it did over the whole summer, from April to the end of August, but the region is still officially classed as being in drought.
