A man has died after his body was recovered from the Chasewater Reservoir in Burntwood, Staffordshire on Sunday evening.
Initial calls at just before 6.00pm suggested two people in trouble in the water, near the Watersports Centre.
Three ambulances, two paramedic officers, the Hazardous Area Response Team and the Midlands Air Ambulances from Cosford and Staffordshire, both with doctors on board, were sent to the scene.
A West Midlands Ambulance Service spokesman said: “A number of boats and members of the public assisted in the search. Firefighters and members of the Hazardous Area Response Team were committed to the water.
“When the 21-year-old man was recovered, ambulance staff tried everything possible, but sadly it was not possible to save him and he was confirmed dead at the scene.
“Thankfully a young girl made it out of the water safely and was unhurt.”
