An emergency is unfolding near South Australia’s Barossa Valley amid reports a man and child have been injured at an old dam.

Police and ambulances have rushed to the Whispering Wall, a 36m high old dam wall in Williamstown, 50km north-east of Adelaide.

A MedStar medical helicopter has also been scrambled, after the emergency call at 4.30pm local time.

The Whispering Wall is the retaining wall of the Barossa Reservoir, according to the website.

“Built between 1899 and 1903, the dam was a revolutionary engineering feat for its day and attracted attention from all over the world, even making its way into the pages of the journal Scientific American,” it says.

“But what draws visitors to the Whispering Wall is its unique acoustic effects: words whispered at one side can be clearly heard at the other, more than 100 metres away.”
