Flood Warning Number: 18

ELEVATED RIVER LEVELS CONTINUING ALONG THE WARBURTON RIVER AT POOTHAPOOTHA

ELEVATED CREEK LEVELS CONTINUING ALONG THE LOWER COOPER CREEK AROUND INNAMINCKA

River levels along the Warburton River at Poothapootha Waterhole are rising slowly as flows continue to arrive from upstream in Queensland. Along the Diamantina River (QLD) at Birdsville, minor flooding has eased.

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

Creek levels along the lower Cooper Creek around Innamincka are currently steady, with further rises expected into early May as flows continue to arrive from upstream in Queensland. Moderate flooding is occurring along the Cooper Creek at Durham Downs.

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 Eyre Creek.
