The Whispering Wall, Barossa Reservoir, South Australia
On our way to the Yorke Peninsula during our holiday last week we stopped for lunch in the picnic area of the Barossa Reservoir. This dam is between the towns of Williamstown and Gawler in the Barossa Valley wine region. This is a delightful spot to picnic and very popular with tourists and locals alike.
The dam wall was constructed between 1899 and 1902 in the shape of a parabola. After construction it was discovered that the dam had a unique acoustic effect, leading to its common name of “The Whispering Wall.” A visitor can stand at one side of the dam, speak softly towards the wall and can be heard quite clearly across the other side, about 140 metres away.
