BOSSES at North West Water have repeated warnings that swimming in reservoirs and lakes can easily turn into a tragic accident.

The arrival of summer means swimmers could be taking dips despite tragedies in the North West last summer, some of which involved pet owners trying to save their animals from drowning.

The message from the water company is clear -- stay away and find properly supervised pools or beaches for a swim.

John Barnes, water services director, said: "Children and young men are most at risk.

"They see a vast expanse of water and are tempted to cool down in the reservoir, but it is a highly-dangerous activity.

"Parents should warn their children of the dangers.

"Reservoirs in use have water drawn from them through pipes under the surface and there are very strong undertows created.

"Many reservoirs slope steeply at the sides so swimmers can find themselves out of their depth before they realise it.

"And the water immediately below the surface is so cold that people can easily get cramp."

The company reaches 32,000 children a year through its SwimSafe campaign but wants everyone to know how dangerous reservoirs can be.

Information about the campaign and where it will visit this year is available on (01925) 233233.
