Roxby Downs shopping mall sustained considerable flooding

Welting thunderstorms served a double dose of torrential rains on towns in the far north east of the state including Roxby Downs, Andamooka, the Flinders Ranges and far north east pastoral, severely damaging roads and flooding properties in the region.

Thursday evening saw the first enslaught with another trouncing early Friday morning.

Approximately 85 mm was recorded at the Olympic Dam mine and up to 150mm at Roxby Downs pastoral lease.

Minor flooding has occurred around the mine resulting in underground activities being temporarily suspended but work is expected to resume by the end of today. Activities on the surface have not been affected.

Safety checks are being undertaken on all equipment and no injuries have been recorded.  BHP Billiton is continuing to monitor the situation.

The Olympic Dam airport has not been affected and services are being conducted as normal. Some flooding has occurred in Roxby Downs with a small number of houses affected.

The Andamooka road received major flood damages

Significant flooding has occurred at Andamooka with major damage to local roads and the main road into the town closed.

Local resident Carl Christensen, Andamooka Opal Miner told regional radio in the morning it was the most rain he’d experienced since 1975.

Coober Pedy, Mintabie and Marla  in the extreme far north were on the fringe of the storm as it passed by threatening, but with no damage.  A small amount of rain was reported.

Leigh Creek in the Flinders Ranges  sustained heavy storms and recorded 60mm.

River heights in the Cooper Creek between Nappa Merri, Qld, and Innamincka, SA, continue to fall.  At Nappa Merri the river has fallen to the minor flood level category. 

Andamooka situated on a creek saw water gushing through the town

At Innamincka the Cooper Creek is above 7 metres; water continues to cross the causeway and flow into Strzelecki Creek.  Strzelecki Creek is flowing into Lake Blanche.  The Cooper Creek continues to flow west across the Strzelecki Desert.  Creek levels between Cullyamurra Waterhole and Innamincka will continue to ease over the coming week.

A surface trough and upper level disturbance moving over the Northeast Pastoral on Thursday and Friday is likely to produce falls in the range of 30-50 mm over the Cooper Creek System.   

At Birdsville the Diamantina Creek is at the minor flood level.  Flood waters continue to flow along the South Australian section of the Diamantina/Warburton Creek and levels are rising in the lower reaches of the creek.  Low flows are reported into Lake Eyre.  Floodwaters from Queensland are anticipated to flow into the lake in approximately a week.    

Travellers to the region are reminded to take care at all creek crossings and to seek information on road and track conditions from the Department for Transport, Energy and Infrastructure at
