The body of missing 13-year-old Ryan Evans has been found in Westport Lake, Stoke-on-Trent.
The teenager was with two other children aged 12 and 13 when he vanished on Monday afternoon.
His companions made it to safety but despite an extensive search operation involving frogmen and shore-line teams, Ryan could not be saved.
A spokesman forStaffordshire Police said: “Ryan’s family have been informed and our thoughts and condolences are with them at this very difficult time.
“His family and friends, who were at the lake with him on Monday, are being supported by police family liaison officers.“
Group manager Brian Moss, of Staffordshire Fire and Rescue Service, urged people not to give into the “temptation” to go into rivers and open water during the hot days.
The lake sits above the old Brownhills Colliery and was formed in 1884, when the workings hit the water table, flooding the tunnels and ground above.
