The water level like this is truly devastating. A lot of people don't realise the sheer power of the flow at that scale. Our house was inundated at about 0.8m level a few years ago, destroying almost everything, breaking gates, fences, moving full shipping containers, etc.
It truly is devastating. The power of water is unbelievable. I am not sure if I remember that happening...but I do remember when you had an incident at your home where you lost the computers and all belongings and ended up buying a new Mac. Not sure if same occurrence or not.
