Flood Warning Number: 13

RIVER LEVEL RISES OCCURRING ALONG THE WARBURTON RIVER AT POOTHAPOOTHA

RIVER LEVEL RISES EXPECTED ALONG THE LOWER COOPER CREEK AROUND INNAMINCKA

River level rises are occurring along the Warburton River at Poothapootha Waterhole following rainfall earlier in the week and as upstream flood waters from the lower Diamantina River continue to arrive. Along the Diamantina River (QLD) at Birdsville, river level rises and minor flooding is occurring. These high flows are likely to continue reaching Poothapootha Waterhole in South Australia over the coming weeks.

River levels further upstream in Queensland, including the Eyre Creek and Georgina River, remain elevated, and major flooding is occurring. Further river level rises and high flows are possible along the Warburton River in the coming weeks as these floodwaters continue flowing downstream into South Australia.

Creek levels along the lower Cooper Creek around Innamincka are currently falling, however, further rises are expected as flows continue to arrive from upstream in Queensland. Moderate flooding is occurring along Cooper Creek at Windorah.

Many roads and access tracks are impacted by flooding, in particular river and creek crossings. Transportation and movement of local communities and travellers are likely to be further impacted. Check road conditions before travelling.

Queensland flood warnings are current for the Georgina River, Eyre Creek, Diamantina River, and Cooper Creek.

Warburton

River level rises are occurring along the Warburton River at Poothapootha Waterhole. Further rises are possible as upstream floodwaters arrive.

Cooper Creek
