Bushfire ash & debris as well as drought now killing fish in NSW coastal and inland rivers

"Fish kills are defined as a sudden mass mortality of wild fish. In NSW we are likely to see further severe fish kills across coastal and inland catchments during the summer of 2019/20....Fish can be directly impacted during fires through extreme high temperatures, loss of habitat, or be threatened from rapid declines in water quality if rainfall occurs in recently burnt areas. Run-off from rainfall events can wash large amounts of ash and sediment into rivers following fires, causing rapid drops in oxygen levels and threatening the survival of fish populations."

The upper reaches of the Clarence River have been badly stressed by low water flows since 2018, so when bushfires began to eat their way through the severely drought affected Clarence Valley in mid-2019 it was obvious that the rolling impacts wouldn't stop when the fires diminished or when rain fell.

There has been a fish kill at Big Fish Flat, an area known for the protected eastern freshwater cod now only found in parts of this river system and commonly known as Clarence River Cod.

The most likely cause of this kill is bushfire ash entering a river which has all but ceased to flow - turning what water there is into a toxic brew.

At Baryulgil on the Clarence est. 1,000 fish died due to low dissolved oxygen within an isolated pool receiving minimal inflows due to drought conditions.

There was also a fish kill on the Mann River, a major tributary of the Clarence which reportedly coincided with ash in the water.

Two fish kills were experienced to the north at Emigrant Creek at Tintenbar in the Ballina Shire and the Brunswick River near Byron Bay - possibly due to low dissolved oxygen within an isolated pool and minimal freshwater inflows. 

Another fish kill occurred to the south on an 8km stretch of the Macleay River where locals describe the bushfire ash and burned debris turning that river's water into a thick sludge killing hundreds of thousands including Australian Bass, Bull Trout, Freshwater Mullet, Eel-tailed Catfish and Eels.

Similarly bushfire affected water ways in the NSW-Qld Border Rivers system appear to have been similarly affected by run-off from the fire grounds and reported fish kills there are being investigated.

All in all a total of 23 coastal and 17 inland NSW waterways have experienced small to large fish kills to date during the 2019-20 bushfire season.

And the drought continues across New South Wales....

There is no land in NSW which is not affected by drought.

Australian Council of Social Service calls on Morrison to increase "seriously inadequate" emergency payments to bushfire victims

The Guardian, 13 January 2020:

Australia’s peak welfare body is calling on the federal government to immediately boost emergency payments for those affected by bushfires, saying it is concerned the current amount is “seriously inadequate”.

The Australian Council of Social Service chief executive, Cassandra Goldie, has written to the prime minister, Scott Morrison, with a range of recommendations the organisation says are urgently needed to help provide relief to those affected by the bushfire crisis that has destroyed more than 2,000 homes.

“It is vital that the federal government continues to play its role providing adequate support to the thousands of people so badly affected,” Goldie said.

“Acoss is very concerned that the current Disaster Recovery Payment is seriously inadequate, particularly for people on lower incomes and with fewer assets, family and friends to secure transport, alternative housing options and immediate recovery resources.”

The group is calling for the payment, which has not increased since 2006, to be boosted from $1,000 to $3,000, and from $400 per child to $1,000 per child. 

Other recommendations include increasing the Disaster Recovery Allowance, which is paid at the same rate as Newstart, which the organisation said was inadequate to cover basic living costs, and providing additional relief for people on low incomes who could not afford insurance.....

Less in response to this ACOSS call and more as pushback against his poor numbers in the 12 January 2020 Newspoll which showed Opposition Leader Anthony Albanese as the preferred prime minister with a lead of 4 points, Prime Minister Morrison has announced an increase in the Disaster Recovery Payment for children to a total of $800 per child from 20 January 2020.

Families who have already received payments for children will automatically be paid an additional $400 according to media reports.

Clarence Valley Council receives $1 million in bushfire recovery funding

The NSW Berejiklian Government has received its state share of the $2 billion in bushfire recovery funding from the federal government and, has informed Clarence Valley Council to expect to have an extra $1 million in its coffers this week.

This money is in addition to grants already received from the NSW Government to assist with repair of certain road infrastructure damaged by the bushfires.

Council expects to use this $1 million grant to rebuild community assets such as sporting facilities and community halls, as well as creating infrastructure which will increase resilience in times of disaster.

The million dollar grant is welcome, however the financial cost of these devastating fires will be a strain on council and local communities for some time to come.

Everytime someone says of Australia 'It's not climate change, it's drought and too much dry fuel in the forests' remember these basic numbers

The Guardian, 13 January 2020:

Australia experienced its hottest year on record in 2019, with average temperatures 1.52C above the 1961-1990 average. Our second hottest year was 2013, followed by 2005, 2018 and 2017. 

New South Wales – one state hard hit by the bushfires – broke its record by a greater margin, with temperatures 1.95C above average, beating the previous record year, 2018, by 0.27C. 

At a very basic level, rising levels of greenhouse gases in the atmosphere change the earth’s radiation balance, allowing less heat to escape. 

Australia also had its driest ever year in 2019, with rainfall 40% lower than average, based on records going back to 1900. NSW also had its driest year....

There have been two other meteorological patterns that helped generate the extreme conditions Australia has been experiencing, and both these “modes of variability” were in “phases” that made conditions worse. 

The Indian Ocean dipole was in a “positive phase”, meaning the Indian Ocean off Australia’s north west was cooler than normal and the west of the ocean was warmer. 

Positive dipole events draw moisture away from Australia and tend to deliver less rainfall. 

But there is evidence that the extra greenhouse gases in the atmosphere are also impacting the dipole and another phenomenon, known as the southern annular mode (SAM). 

A 2009 study found that positive dipole events “precondition” the south of the country for dangerous bushfire seasons and that these events were becoming more common. 

A 2018 study in the journal Nature Communications found the number of extreme positive dipole events goes up as climate heating continues.

The Australian Bureau of Meterology has produced two charts which display the stark transformation in temperature and precipitation across the continent over the past century.

The first chart shows the anomaly of mean temperature for each calendar year from 1910 to 2019, compared to the average over the standard reference period of 1961–1990.

The colours range from dark blue (more than 3 degrees Celsius below average), through blues and greens (below average), yellow and orange (above average), and then brown (more than 3C above average).

The Bureau has also produced a second chart showing rainfall in each year since 1900.

The colours range from dark red (lowest on record) to white (average) and dark blue (highest on record).

Rain predicted across NSW from today but it's not all good news - may be landslips, fallen trees & flash flooding on land burnt by bushfire since August 2019
