Rain glorious rain - shall we rename to Colliwat Cascades?

After a protracted dry spell which saw our tanks empty and our dam shrinking so low we had decided to stop watering the vegie patch for fear of desiccating our native fingerlings, we were blessed with two days of solid rainfall.  Unfortunately our rain gauge is still attached to the roof of our old place so we don't have an accurate measurement of the amount or rain.  According to the weather maps we had between 100 and 150mm of rain over the two days.  

It's certainly been a long time (and only the second) since we saw the dam overflowing.  This was the most spectacular overflow yet and we were also able to witness the neighbours' dams cascading over and into our dam for the first time.  Even when flooding is in the back of your mind, the sound of rushing water is so fulfilling.

It was also a good opportunity to find out how our place would flood.  We were told by the neighbours that the previous owner had renovated the driveway and put in a stormwater drain for overflow as the driveway was flooded and washed away in previous heavy rainfall and flooding.  They'd had to make do by parking at the front of the property to ensure they could get out and the driveway had been patched up with a couple of planks so as not to get bogged in the mire.  We're certainly grateful for the improvements.

Here are some afternoon before and morning after shots of the dam showing the near instant filling:

As you can see even where I was standing for the first photos is now covered in water.

We were fortunate to have a couple of sunny days after the rain to allow things to green up, shoot off and soak in the rain.  Today the rain has come back but is falling gently at the moment.
