The water quality of Lake Wyangan is being analysed as part of a nationwide scientific study.
Researchers from Griffith University in Brisbane are investigating the impact of water levels on water quality and Griffith's lake has been selected as one of the case studies for the research.
In-depth data from more than 10 Australian lakes is being closely examined, in order for leading scientists to gain a better understanding of why and how water quality changes.
Major bodies of water such as Lake Burragorang are involved, with Lake Wyangan providing an example of how water quality changes in a very shallow lake.
Dr Philip Orr, adjunct senior research fellow at Griffith University's Australian Rivers Institute, says better understanding how the lakes work will help improve water quality down the line.
"Understanding the impact of water level changes on water quality is just one part of a bigger picture to better understand how lakes work in Australia," Dr Orr said.
"Fixing the problem of blue-green algae in our lakes is going to be a long-term project and it's all about understanding exactly how the lake works and unfortunately that's not going to happen overnight."
Dr Orr said preliminary findings from the study will be released in the next few weeks.
Lake Wyangan and catchment management project officer Tom Mackerras said Griffith City Council was glad to have some of the country's leading researchers analysing water quality from the lake.
"We're hoping to get a benefit out of it," Mr Mackerras said.
"We've got the scientific gurus taking a look at all the data that has been collected over the years and taking a scientific approach to it all and what they find will help inform us."
Lake Wyangan is currently in red alert due to high levels of blue-green algae.
Efforts are being made to improve the water quality and last month Griffith City Council approved the addition of 2700 megalitres of water to fill the lake for the first time since 2016.
