My father lived and worked on Doolgunna Station, about 120kms N of Meekatharra, during the Great Depression, from early 1930 to sometime in 1934. Doolgunna is in the upper catchment area of the Gascoyne River.
He would also spend time working as a fencer on numerous other stations in the Gascoyne region. He then spent a further 3 years doing water-boring in the same region and further afield, right down to the Northern Wheatbelt of W.A.
In March 1934, a big cyclone cut across the Gascoyne region, bringing huge falls of rain with it. Dad and two other blokes were fencing on station further West from Doolgunna, I think it may have been Three Rivers Station, but I'm not sure now. Three Rivers has frontage to the massive Gascoyne River.
Anyway, where they were working was in the Gascoyne flood plain. They each had horses and a camel-drawn dray with supplies on it, designed to last about three weeks at a minimum.
Dad said it started raining, and rained heavily, non-stop for 3 days. They got around 15 inches (380mm) of rain in that three days. He said the curious thing about the whole episode was, just before the rain started, the three camels they had on the dray, laid down, turned their heads against their flanks - and died!
He reckoned they somehow knew a big flood was coming, and camels can't handle wet muddy conditions, their legs splay out in greasy mud, and they bellow out in pain.
So, they stopped working for three days - and next thing, the floodwaters from the rising Gascoyne started surrounding them! Their swags and tents were getting wet, so they built a platform in a nearby windmill tower, about 3M off the ground, and set up camp up there to wait out the flood. It was too risky to return to the station, because they had to cross the Gascoyne to get there.
They sat it out on that windmill tower platform for THREE weeks! The water around them rose to top-of-fencepost height, and just stayed there for all that time. Dad said nearly every fencepost top they could see, was covered in scorpions, snakes or other creepy crawlies, all trying to survive the flood! He said there was water as far as the eye could see, from the top of the windmill tower.
Finally, the floodwaters started to recede, and one of the blokes decided he'd try to return to the station to let the owners know they were still alive, and not washed away, and to get some fresh tucker.
But he tried to swim the Gascoyne, which was still flowing well, and he ended up losing his horse (and a good saddle, too! - according to Dad) - and he nearly lost his own life, getting swept well downstream, before he could grab a tree and climb out.
The other blokes were surprised, when he walked back into camp, with no horse! So they had to wait several more days before they could get out and cross the Gascoyne safelys and return to the homestead.
Here's some of the storm reports from the end of March 1934, that show the vast area flooded by that cyclone. Only a fortnight before, the SW of W.A. received huge amounts of rain as well, from a different cyclonic event. Some places in W.A.'s wheatbelt received 5 inches (125mm) of rain in one day, around 9th-10th March 1934.
