Cooks River at the Illawarra Road bridge Marrickville

Cooks River at the Illawarra Road bridge Marrickville

Today I received the following email from Gayle Adams, the Water Quality Co-ordinator for the Cooks River Valley Association.

“On Saturday 1 December around 3:30 pm with the tide halfway out, one of our keen-eyed members reported seeing a great number of dead fish near the bridge over the Cooks River at Illawarra Road/Homer Street.

Have you seen dead fish in large numbers in the River lately? Or something you think might be related?  If so, please let us know by return email so we can accurately log this latest fish kill.

The last major fish kill in the Cooks that I am aware of was November 2008 which we think was mullet adversely affected by a toxic discharge from the stormwater drain at Younger Avenue Earlwood.  But fish kills can happen due to ‘natural’ causes. It looks like oxygen levels in the River were very low in the days before last Saturday & Saturday itself was very hot.”

If you have seen something, please contact Gayle at info@crva.org.au
