The latest report card of South East Queensland waterways shows water quality in Gold Coast catchments are improving.
The Healthy Waterways: One Clear Vision report, by SEQ Catchments gave both the Pimpama/Coomera and Tallebudgera/Currumbin catchments a B grading – up from C-plus last year – while the Nerang catchment rose from a C-minus to a C grading.
Chairman of the Healthy Waterways and Catchments Science Committee, Professor Stuart Bunn credited this year’s higher rating to improved conditions from less pollutants in the waterways. But he added that sediment pollution remains the number one pressure threatening South East Queensland waterways.

“The amount of sediment pollution entering the waterways is driven by rainfall, but is also strongly affected by the condition and management of the land,” he said.
“This year the upper catchment region suffered below average rainfall, and as a result pollutant loads declined.L This reduces the threat downstream and the condition of coastal waterways tends to improve during these times,” he said.
Professor Bunn stressed the need to build the resilience of our catchments against future rainfall events if we are to maintain the improvements we have seen this past year, and protect the benefits our waterways provide through tourism, recreation drinking water supply and agriculture.
