46 Sydney Harbours in 12 months Murray R. flows to SA

The ample MDB rains of 2022 following two good years have lead to the 46 Sydney Harbours (23,377GL) flowing into South Australia.
This eye watering volume of fresh water has originated as rainfall. The MDB is ~1million sq km so if 500mm rain fell on average in 2022 that is 0.5GL x 1million or 500,000 GL or 1,000 Sydney Harbours of rainfall.
Now there is evaporation, soakage into the ground, recharging of acquifers, as these colossal floods move on their pathways over the MDB landscape and make their way to the Murray R.
The Minister for the Environment and Water Tanya Plibersek is still demanding NSW & Vic waste more water to the sea by way of Environmental Flows agreed to years ago. Water ministers fail to agree on way forward as Murray-Darling Basin Plan deadline looms 24Feb23
Four months ago I blogged –
MDB floods widespread but GreenLabor planning huge enviro flows 31Oct2022
I said then [The Minister seems to be gloating about stopping previous Gov dam projects, already stalled in antidam State bureaucracies, and using the $Bns to buy water out of the MDB plan for future flushing down to the sea.
Making the MDB a smaller & less important future food-bowl and the wide brown land will be a weaker food producer.]
