Issued at 1:54 PM AEST on Tuesday 3 Mar 2026.

Flood Warning Number: 62

MAJOR FLOODING POSSIBLE AT WINDORAH FROM OVERNIGHT TUESDAY INTO WEDNESDAY

MODERATE FLOODING OCCURRING AT LONGREACH AND STONEHENGE

A renewed moderate flood peak was observed early Sunday morning at Longreach. Further downstream at Stonehenge, river levels are slowly rising above the moderate flood level. River levels are expected to remain above the moderate flood level for the next few days, with further rises possible.

Along the Barcoo River, the main peak is approaching Retreat, where minor flooding is occurring and is expected to continue for the next few days.

Along the Cooper Creek, renewed moderate flooding is occurring at Windorah (Main Channel) and major flooding is possible from overnight Tuesday into Wednesday. Further rises are likely as upstream flows arrive from the Thomson and Barcoo Rivers.

Peak forecasts will be refined as upstream peaks are observed.

In the lower Cooper Creek catchment, moderate to heavy rainfall was recorded in the last few days which has caused minor to moderate flooding along the lower Cooper Creek and its tributaries.

Thomson River

Minor to moderate flooding is occurring along the Thomson River and its tributaries.

Barcoo River downstream of Isisford

Minor flooding is occurring along the Barcoo River at Retreat.

Cooper Creek
