Northumbrian Water is warning people of the dangers they face when they attempt to swim in its reservoirs.
The operational sites have many hidden dangers underneath the water. These can include unknown depths, extremely cold water, machinery and really strong underwater currents as the water is pumped from the reservoir through to the water supply chain so even the strongest of swimmers can get into serious difficulty.
Don Coe, Northumbrian Water′s Waterside Parks operations manager, said: "We want people to have fun and enjoy the sunshine, but not at the expense of their own safety and that of their friends and family.
"Learning to swim really can save your life and, while swimming pools are the safest places to swim, there is always the temptation to have fun wherever there is water, such as reservoirs or lakes. This is especially true during periods of warm weather like the one we have been experiencing in the last few days.
"Northumbrian Water has a ′no unauthorised swimming′ policy in place on all of its reservoirs. Reservoirs are operational assets, which contain unseen hazards that have the potential to be life threatening if water sports, including swimming, are not carried out by authorised clubs and personnel.
"People are also often not as aware as they should be of issues such as cold water shock. This can prove fatal as people′s bodies react to the temperature change and they lose their ability to respond and save their own lives."
