Storm activity arrived in October, allowing the ground to soak in some much needed rain. But the mere presence of rain, is NOT the cue for our growing season to begin, in earnest. Especially if it's been dry.
What our best cue is, however, is the lower gully, flooding...

It took several days of rain, for the ground to be soaked and allow water, to run on the surface again. A good week of rain, saw water rising, but it was a gentle flow. Good for avoiding erosion.
Even though we saw water in the gully - moisture in the ground wasn't going to last long, once the sun came out again. Which it did, and the ground slowly began to dry out. But then the second storm, told a different story...

It was a small event, compared to some regions in Queensland, but our whole gully was flooding, because of that storm. Which is the best cue I could receive for the growing season.
Because we have 3 channels of water that disperse in our gully, when it floods. When they all join together, I know the ground is more likely, going to stay moist for the rest of the growing season. So it's not just the gully flooding, which is my cue, but how many channels are flooding at the same time.
Entering
It all starts when the water enters our property, from several of our neighbours upstream. The water entering our property, is always red, because no-one attempts to hold the water back, further up. So we end up with soil from the properties upstream.
As it's a narrow channel, the water enters fast. But when it comes onto our property, it immediately disperses as far as it can spread. How much water, determines whether all 3 channels, will flood.
Dispersing
In this particular storm event, all three did! The upper channel (highest ground) is furtherest away. The middle channel is, of course, in the middle - with the lowest channel, being on the bottom of the picture. The lowest, is the least likely to flood, but when it does, I know there's a good amount of water in our gully now.
Here's what all three channels joining together, look like, in the middle of our property...
Mulberry, centre
It flows like a river. When the mulberry is surrounded by water, I know it's set to survive the heat of summer. So our mulberry in the middle of our gully, is another potential cue I look forward to. Although the heat of summer is still yet to come, the ground has been flooded with water. Which is a good sign.
Because when you live in the bush like we do, it's a good to have the ground saturated, before summer arrives in earnest. I must confess to being a little nervous about the prospect of bushfire season, before this rain arrived.
Near the end
Further downstream from the mulberry, the water is dispersing more and therefore, slowing further. Our lucky neighbours downstream, have little to worry about the water entering their property. It's slower, less aggressive, and therefore less dirty water. Especially once it passes through our wide thicket on the boundary.
Flooding
30 minutes after the rain had stopped, the water receded again.
Receding
So the gully is completely dry again, and will await the next storm to overflow it. I like having this gully in the middle of our property - even if it cuts us off from the other half, when it floods. Because it's the perfect visual to tell me about the growing season.
Summer will still give my systems a hard time, because the heat is always so intense here. But knowing the gully has flooded completely, cues the growing season for us, in earnest.
