Brisbane River fails health test
THE Brisbane River will be targeted for improvement after it received the worst rating of south-east Queensland catchments in the 2012 Healthy Waterways report card.
The mid-Brisbane River catchment, from the Wivenhoe Dam gates to western Brisbane, received an F, the worst grade for a catchment in the report.
The Bremer catchment received a C grade, the same as last year; the upper-Brisbane catchment, north of the Wivenhoe dam wall, saw a slight increase from a C- to a C; while the Lockyer catchment received the same result as it did last year, a D+.
Near Lowood, the mid-Brisbane River saw thousands of catfish die due to an infestation of white spot last month.
Ipswich council environment and Environment and Conservation Committee chairwoman Cr Heather Morrow said the council was working to improve the quality of local waterways.
"Today's report card, while a marginal improvement over recent years, does not highlight the volume of work being done to help improve water quality," she said. "The Bremer is a challenging river system as it does not always have fresh water inflows from its upper reaches."
Cr Morrow said the council was committed to improving the condition of the Bremer and Brisbane rivers.
"In the 2012-2013 council budgets, we announced a new focus on rehabilitating the fresh water reaches of the mid-Brisbane and Bremer river catchments which will eventually benefit downstream flows," he said.
"The Bremer River upstream from Sadliers Crossing has received its best-ever rating of C and confirms the efforts by landowners and council are helping to improve the health of the Bremer River."
Somerset Cr Jim Madden said his council was working to improve the condition of the Brisbane and Lockyer catchments.
