Another warning has been issued about the dangers of swimming in open water during South Yorkshire’s heatwave.
Barnsley Council is asking people not to swim anywhere other than purpose built and supervised swimming pools.
Councillor Jim Andrews, the council’s cabinet spokesman for public health, 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.”
