Victoria, Australia · Upper Murray · January–February 2026
Someone reading the Upper Murray community bulletin on 12 January would have seen a fire estimated at about 100,000 hectares and still growing. Someone reading a catchment assessment a month later would have seen an estimate of about 121,500 hectares. Both estimates are useful, provided the date travels with the number. Neither gives a reliable daily rate of spread.
Two snapshots of the same fire
The fire began on 5 January in Mount Lawson State Park. The 12 January incident newsletter gave residents an approximate footprint during operations. The North East Catchment Management Authority update describes the area as of 12 February, from the Murray River towards the Wabba Wilderness. Subtracting the January estimate from the February estimate would give a difference between two reported numbers. To determine where the fire actually advanced between observations, we would need comparable perimeter geometries and survey times. A revised map can change the measured area without representing new spread on the day of publication.
Which date belongs in the containment field?
Forest Fire Management Victoria gives 2 February as the containment date. The Victorian Government submission to the parliamentary inquiry also records containment on 2 February and a subsequent change to Under Control 1 on 13 February. The catchment authority gives 6 February for containment. We retain 2 February as the operational date and flag 6 February as a conflicting published date. The records cited here do not explain the discrepancy.
What earlier fuel treatments can and cannot show
The operational account describes a steep, wooded landscape where earlier fuel treatment helped firefighters gain access and work on the fire. That is a claim about what crews could do at particular locations. It is compatible with a large final footprint: safer access along one approach need not halt spread on every other flank. To estimate hectares saved, an analyst would also need a defensible comparison with fire behaviour under the same weather and terrain without the treatment. A perimeter and a crew account do not supply that comparison.
What belongs in a comparative archive
Keep the January footprint as a dated estimate, the February footprint as a later assessment, and the containment discrepancy alongside both source links. A reader comparing response milestones can then use the operational chronology; a reader investigating land impacts can follow the catchment assessment. The choice of source follows the question.
