At a Glance
- The Leichhardt River in Northwest Queensland, Australia, is currently experiencing major flooding following a peak of 16.25 metres at Lorraine, with the surge now moving downstream toward the Gulf.
- The Leichhardt River in Northwest Queensland, Australia, is maintaining major flood levels following a peak of 16.25 metres at Lorraine, with major inundation now firmly established downstream at Floraville.
Status & Severity
- A Major Flood Warning remains active as the flood peak traverses the lower reaches. The river reached a critical high of 16.25m at Lorraine and is currently rising at Floraville, where major inundation is expected to persist for several days.
- While levels at Lorraine have begun a slow recession (dropping to approximately 16.00m), the flood peak is now concentrated at Floraville. With more rain forecast for the weekend, river levels are expected to respond quickly and could see secondary rises.
Affected Communities & Regions
Lorraine: Levels remain high but are slowly falling after a 16.25m peak.
Floraville: Currently experiencing major inundation; access is severely restricted.
Burketown: Watching for downstream impacts; Doomadgee Road is closed to all traffic.
Mount Isa Catchment: Saturated ground means any new rainfall will cause immediate runoff into the upper Leichhardt.
Gulf Country: Significant isolation continues for pastoral stations as the Burke Developmental Road remains closed at multiple points.
Local Landmarks & Interest
Floraville Station Crossing: High-risk area currently monitoring rapid rises.
Lorraine Bridge: Recently impacted by the 16.25m peak surge.
Leichhardt Falls: Significant volume increases making the area inaccessible to travelers.
- Wills Developmental Road: Closed in both directions between Four Ways and the Burke & Wills Roadhouse due to long-term flooding.
Data Sources & Verification
Information compiled from the Australian Bureau of Meteorology (BoM), local station data in the Gulf Country, and verified on-the-ground visual reports from the Queensland Disaster Management Portal.
Historical Comparison
This event is currently drawing comparisons to the record major flood event of February 2023, which saw prolonged community isolation across Northern Australia. Check our archives for more Queensland river data.
Regional Context: The Northern Australia Monsoon Surge
The current flooding along the Leichhardt River is not an isolated event but a symptom of a broad and intensifying monsoonal activation across the continent’s north. As outlined in our regional analysis, the 2025–2026 wet season is characterized by a “stationary low” pattern that mirrors the devastating 2023 events but with increased velocity.
Why this matters now:
Infrastructure Strain: Massive water volumes are testing the “flood-proof” upgrades on the Wills Developmental Road, as silt-heavy runoff threatens to bypass modern culverts.
Stationary Tropical Lows: Unlike typical fast-moving cyclones, the current system is “stuck,” drawing a continuous moisture plume from the Coral Sea directly into the Gulf catchments.
Predictability Gap: Rapid “flash-to-flood” transitions in the upper Leichhardt near Mount Isa are challenging traditional downstream crest models, which historically relied on slower-moving surges.
