Adelaide's wettest July in 17 years

Adelaide has recorded its wettest July in 17 years, but the deluge has also caused flooding across parts of the state.

Unrelenting rain has turned some properties at Finniss into pools, with run-off from roads and blocked drains adding to the saturation.

Finniss resident Neil Young told 7News the same thing had happened ‘three out of the last four years’.

“It’s flooded right around our house, it’s flooded right up to the paddocks where our horses are,” he said.

Falls of up to 150mm in some areas turned rivers into raging torrents, but there is a silver lining.

More than 18 billion litres of water have poured into reservoirs.

On the weekend alone, holdings increased by seven per cent, up to 55 per cent capacity.

The deluge also had the Clarendon weir overflowing, while SA Water is having to open the gate at Myponga over the next couple of days to release billions of litres.

Paul Lainio from the weather bureau said it is the highest July rainfall in 17 years.

“In July this year, we’ve had 110mm, that’s the biggest falls since July 1996,” he said.

Rain will continue to ease over the next 24 hours, but the break will be short-lived, with more showers forecast for Sunday.

The longer-term outlook sees a great chance of the wetter conditions continuing.
