Somerset Council Adopts Advanced Flood Mapping

SOMERSET Regional Council has adopted the most recent and technologically advanced flood mapping available for the south of the region.

The comprehensive data has been made available through the Brisbane River Catchment Flood Study that was released on Friday, 5 May.

The study provides an in-depth analysis of a range of flood events that may occur within the Brisbane River floodplain and is a critical step towards developing a strategic floodplain management plan for the region.

Council considered the report and the flood mapping data during its meeting on Wednesday and agreed to replace existing flood maps with the advanced data.

Somerset Regional Council Mayor Graeme Lehmann said this was the most detailed and comprehensive flood study ever undertaken in Australia.

“This new data provides a greater understanding of the Brisbane River’s behaviours across not only our Council area but that of three other Council areas in south east Queensland,” Cr Lehmann said.

“With the Somerset region containing Wivenhoe and Somerset Dams the study was very important to the region’s future.

“The Flood Study uses cutting-edge technology to model flooding downstream of Wivenhoe Dam including the Brisbane River and major waterways including Lockyer Creek, the Bremer River system and Oxley Creek.”

This study is a critical first step towards developing a strategy that will set out flood resilience options for the region.

The Queensland Floods Commission of Inquiry recommended the study be undertaken because there was no single flood model that Councils could use that provided a common and consistent basis for land-use planning, disaster management and building community resilience.

“It will enable us to work with the government and surrounding councils to coordinate planning, preparation and responses to flood events that may occur in the future.”

The flood models developed as a result of the study have been verified against the flood events that occurred in 1974, 2011 and 2013 and endorsed by an independent panel of experts.
