Two men had to be rescued by firefighters after going for a dip in a St Helens lake.
The duo got into difficulty while swimming towards a buoy in Eccleston Mere - near Burrows Lane, Eccleston - amid soaring temperatures on Saturday evening (June 21).
Emergency crews were called to the scene shortly before 7pm.
A firefighter in water rescue kit entered the water to complete the rescue.
He was assisted by another firefighter on the shoreline who handled the safety tether - a piece of rope attached to the rescue swimmer to help bring them safely back to shore.
The two men were assessed by paramedics at the scene and taken to Whiston Hospital for further checks.
Fire station manager Dave Watson said: “We were called after reports of two men in the water in distress.
“Firefighters from Eccleston immediately deployed a rescue swimmer. The rescue swimmer found one male was in particular distress and struggling in the water and brought him to safety.
“The other swimmer, who had started to swim towards the shore and safety, then showed signs of distress and was also brought to safety.”
He added: “During the summer it can be tempting to take a dip in open water to cool down, but you are putting yourself at risk.
“You do not know what obstacles are under the water which can catch your legs and arms. There are also other dangers.
“Water poses a range of dangers including cold water shock which can lead to the strongest swimmers getting into difficulty during the warm weather in the summer.
“All operational firefighters in Merseyside are trained in still water rescue for incidents in or near lakes, docks and canals.
“We would urge everyone to stay safe this summer whether on, in, or near water.”
