THE warm weather has sparked an increase in open water swimming which can have deadly consequences.

As school holidays are approaching increasing numbers of young people are putting themselves at risk by swimming in rivers, canals, ponds, quarries and lakes.

Barnsley Council are urging people not to swim anywhere other than in purpose-built and supervised swimming pools unless they are a member of an organised swimming group.

Coun Jim Andrews said: “We understand that during the warm weather open water looks inviting, but it really isn’t worth the risk. Swimming is not allowed at any of our open water sites and there is no supervision.

“The water may look calm on the surface, but there can be strong undercurrents that could pull even a strong swimmer under the water. Also just a few feet below the surface the water can be icy cold. This can affect stamina and strength of swimmers.”
