Another interesting thing is that if there is water it tends to move around a lake. Some locals say its to do with the moon & tides. Others say its wind.
It's definitely wind. When Len Beadell & his gang were building the Gunbarrel Highway they camped on a salt pan one night. There was water up one end, so they set up camp at the other end. They woke up during the night to find everything floating, as a strong wind had come up & pushed the water in the opposite direction!
