A teenager has drowned after swinging off a rope and jumping into a river west of Sydney.

Police divers found a 19-year-old's body in the Hawkesbury River at Windsor about 6pm on Saturday.

The teenager is the third person confirmed drowned in NSW waterways in three days. A fourth person remains missing, feared drowned.

Michael Ryall, 16, drowned while fishing with his brother at Wentworth Falls Lake in the Blue Mountains on Wednesday.

His wife was safely washed back onto the rocks.
