PEOPLE are being warned not to swim in reservoirs.

Yorkshire Water has issued the message after a rise in reports of people taking a potentially-fatal dip at its sites – and recent water-related tragedies in other parts of the UK.

Gaynor Craigie, for Yorkshire Water, said: “As summer approaches and the weather warms-up it is important that visitors to our reservoirs are not tempted to get into the water to cool off. Sadly recently in the UK we’ve seen the dangers water can pose.

“Low water temperatures can cause ‘cold water shock’ that may lead to hyperventilation, increased blood pressure, breathing difficulties and ultimately death.

“Underwater machinery and the currents associated with their operation are also a potential hazard for people choosing to enter the water.

“We recently backed the National Fire Chiefs Council’s Be Water Aware campaign and would encourage those visiting our reservoirs to do so safely, which means not entering the water and putting themselves at risk.

“If visitors do see someone in the water who requires help, they should call 999 and ask for the fire service immediately – as crews are trained and equipped to deal with such incidents.”
