Drought and bushfires had already taken a huge toll on the Eurobodalla Shire's native fish.
Reduced river flow during drought conditions sees fish unable to access their usual range and water heating quickly on hot summer days.
These conditions reduce the available oxygen in our waterways and fish die.
Fish kills, which are the mass mortality of fish, have recently been recorded in the shire at Tilba Lake, Whittakers Creek and the Deua River, and bushfire presents additional threats to our native fish stock.
During a fire the water in creeks and small pools can heat to the point where fish die.
Then, after a fire has passed, ash and sediment falls or is washed by rain into waterways.
Water becomes murky and there may be a sudden drop in oxygen when bacteria proliferate as they feed on the influx of organic matter.
Manager of environmental services Deb Lenson said the council will monitor water quality in local estuaries.
The council is also working with South East Local Land Services to install sediment and erosion control - helping to protect the shire's waterways.
"We're seeking funding under the NSW Government's Bushfire Affected Coastal Waterways program to implement immediate measures which help protect water quality and coastal ecosystems," Ms Lenson said.
"In turn, this assists our tourism and aquaculture industries.
"We'll also be seeking technical and financial support for longer-term help for our waterways.
"The task has only just begun, our native flora and fauna will need a lot of help.
"Forecast rain this weekend is much needed but will bring with it a host of new issues for the natural environment."
Ms Lenson said residents and visitors can help the shire's native fish by keeping an eye on local waterways, reporting any gasping fish or fish kills to the Department of Primary Industries' Fishers Watch Phoneline on 1800 043 536.
