Greetings,
it was in the Great Artesian Basin, Australia’s driest and hottest and strangest spot. A relentless sun above, below the largest fresh water reservoir in the world. The rivers mostly dry, the trees along them living on the memory of water.
I camped at Eyre Creek. A tiny sprig floated very, very slowly from right to left. I put up tent, played with dog Rusty, cooked a meal. Then a gentle breeze came up, and that sprig, like an old friend, came back again - floating very, very slowly from left to right.
With an average gradient of 17cm/km that land is so flat even a weak breeze can change the flow of a river. Madigan, some 70 years back, had observed the same. Much of the land is covered by stony deserts. Explorer Sturt in 1845 '..the most cheerless and the most forbidding of any landscapes our eyes had wandered over..’
No Kentucky Fried, no MacDonalds - and no tourists. I love that piece of land.

Hi Folks
When you get an expanse of water and little fall the natural forces have a big effect. Moon phases barometric pressures and wind over a shallow surface can all affect liquids, the more fluid and little gradient I would think would create a bigger effect.
Just like the old barometers, still measured from the same base.
Last time I crossed Eyre creek even the
Dingo Poo was not moving.
I am sure it will be
well flushed now.
Tide, Wind, Baro pressure will change where the water is or flowing, ie shallow mass of a liquid body and external forces will make it move even uphill?.
It Will Move when nature lets it.
Cheers
Russ
