With water temperatures as low as 12ºC, depths of up to 50m and undercurrents lurking beneath the surface, the Cold Water Kills film highlights that even a short swim could end in tragic consequences.
Produced by Yorkshire Water and West Yorkshire Fire & Rescue Service, the film is aimed at young people who are most likely to be tempted to swim in reservoirs during the school summer holidays.
It was filmed at Ogden reservoir in Halifax and features a hard hitting recreation of a reservoir emergency rescue that ends in tragedy.
In the last five years alone, West Yorkshire Fire and Rescue Service (WYFRS) has been called out to 107 water rescue incidents across the county - nine of which resulted in deaths.
The most recent reservoir fatality was at Snailsden reservoir in South Yorkshire last summer where a police dive team found the body of a 38 year-old man on the surface bed.
Alastair Harvey, Recreation Advisor at Yorkshire Water, said: “Reservoirs may look tempting to take a swim in but they can be killers and our dramatic film will hopefully raise awareness of these risks amongst young people. Cold water shock can lead to hyperventilation, increased blood pressure, breathing difficulties and heart attacks plus water temperatures remain just as cold in summer as in winter.
“We have 115 scenic and beautiful reservoirs that we want walkers, cyclists, runners, picnic-goers and others to enjoy this summer. We just don’t want anyone to swim in them and to obey our warning signs.”
Station Manager Ian Thompson, a Technical Rescue Officer for West Yorkshire Fire & Rescue Service, said: “Too often in the past people have been drawn to the cooling waters on a hot day, only to find that they are simply not capable of functioning in the low temperatures encountered in the deeper water.
“As the school summer holidays start it is vital that youngsters take our safety messages on board when they are out and about.”
Across the UK, there was a total of 381 drownings and water-related deaths in 2013 with over half occuring in inland waters, such as reservoirs, lakes and rivers.
