There’s a warning for people not to swim in reservoirs as temperatures rise to a predicted 29C (84F) this bank holiday weekend.
Yorkshire Water said that while reservoirs may appear inviting during warm weather, but there’s always the risk of cold water shock. Hidden currents lie hidden beneath, along with sudden drops, submerged structures and operational equipment.
“Sadly, we’ve seen incidents this year in Yorkshire where people have lost their lives in reservoirs and other open water,” said Alastair Harvey, lead countryside and woodland adviser.
“Don’t be tempted to go for a dip in the shallows or walk on the exposed embankment and structures, as there can be risks of sinking mud.”
Yorkshire Water rangers will be at the region’s 120 reservoirs over the weekend to encourage considerate behaviour, with barbecues and fires not permitted at any site.
Some locations are covered by public space protection orders (PSPOs), meaning people could face on-the-spot fines if they breach the rules.
Water sports such as sailing and windsurfing are only permitted through authorised clubs.
Despite predictions of a heatwave, Yorkshire Water said cooler temperatures and more rainfall in 2026 meant reservoir stocks were healthier than this time last year.
The reduced demand for water and reduced leakage meant they were currently 86.4% full, up from 66%.
Customers are still being advised to use water wisely, such as watering gardens with a can rather than a hose.
