Fishermen were disturbed by the sight of dozens of dead cod floating on green paint-like scum on the Macintyre River almost a fortnight ago. Experts blamed the abundant sunlight, slow-flowing water and sufficient levels of nutrients.

The red level warning issued for blue-green algae continues to be in effect.
Central and North West (Barwon, Macquarie and Far West) Algal Coordinator, Tracy Fulford, said that the photographs that he has seen since the recent rainfall has shown a slight improvement, however the area continues to be unsafe.
“We took more samples from the river, however the results will be back at the start of the week,” said Mr Fulford. “There have been some flows, but the area near the bridge at the Bundarra crossing still looks problematic.”
Mr Fulford cannot predict how long it will take for the red level warning to be lifted but explains that the appearance of algae is a naturally occurring phenomenon driven by dry and hot weather conditions. “It can’t be fixed until you get a flushing event to dilute it,” he said.
An amber alert is also in place for Copeton Dam and the wider region is being monitored.
People should not undertake recreational activities where they may come into direct contact with water in contaminated areas, as this could lead to skin irritation. For animals, drinking this water could mean death and livestock owners are advised to remove stock from foreshores. “Fishermen should make sure they wash the fish in clean uncontaminated water, including the innards,” said Tony Webber from Water NSW.
Town water supplies remain unaffected
