Yilgarn Water - Video

Equinox - Re the "overflow tank" at Kurrajong - the small tank is called a silt trap, and is located in front of the main tank.

The idea is, the inrushing water is slowed up in the silt trap, and it then drops a large percentage of the silt and debris it is carrying into the trap, before it overflows into the main tank.

A silt trap is a reasonably effective, if crude, method, of stopping the main tank from rapidly filling with silt, and then ending up only holding half the water it's designed to hold.

Speaking from over 40 years experience as a damsinker, water harvesting, and drainage contractor.

Thanks for the video, it looks like it rained not long before you went through there.

Not a lot of people understand how a full gnamma hole, or an empty gnamma hole, made the difference between surviving and "doing a perish", when travelling, in the early days of W.A.'s development.

Horses in particular, demand sizeable amounts of water on a daily basis, and you read about so many of the early travellers and early farmers drinking water from polluted waterholes, whilst travelling, that you wouldn't normally touch - because there was nothing else.

Cheers, Ron.

Thanks for the well made video. This is by no means a criticism of the item but it says something about the way we have buried local history that there is no ready information about the Aboriginal peoples who originally used these soaks and waterholes. The arrival of "explorers" and the cattle usually meant a serious impact on the survival of the indigenous people. Mobs of cattle would muddy up water holes and we can be sure if the Aborigines of the area sought to drive cattle away or speared trespassers then the reprisals would be brisk and punitive.

It is only relatively recently that we have begun to peel back the layers and learn the realities of conquest. The Guardian recently began a project which provides rather more detail than we ever learned in our "history" lessons. For anyone interested here is a link although most of it relates to Eastern Australia and with little about the west.

Thanks for sharing.
So much history out there.
I will be in that region in a few weeks.
You have whet the appetite.
Cheers
