Revised Flood Studies
Revised Flood Study: Dalby
In July and August 2025, we asked Dalby residents to take a look at the existing flood study reports and share their local knowledge to make sure the new models match what really happens during flooding events.
This input will help improve the accuracy of new flood modelling and maps - and we'd like to thank everyone who shared local rainfall records, knowledge of previous flood experiences and photos of historic major rainfall events.
We're combining this important community feedback with data from the 15 river, rain and water level monitoring stations on and around the Myall and Cooranga Creek catchments.
The updated model will also consider breakouts from Spring Creek, which also have the potential to impact Myall Creek flooding.
Dalby has an unfortunate history of riverine flooding from the Myall Creek catchment and flash flooding from localised heavy rainfall events and severe thunderstorms.
Council is revising the Dalby Flood Study undertaken in 2014 to provide better understanding of flood behaviour throughout the Myall and Cooranga Creek catchments, to improve flood management and disaster response, and provide up-to-date information for infrastructure planning and land use.
The revised models should be available for community feedback in November 2025 through a series of drop-in sessions.
This project is fully funded by the Australian and Queensland governments under the Disaster Recovery Funding Arrangements.
Stantec has been engaged to deliver and coordinate the revised flood studies across the six Council areas.
