Having a river in your backyard is a lovely idea, not always so pleasant in reality, as fences and dead animals go swirling past in a flood, or when you find out that a city upstream is putting something in the water that shouldn’t be there.
Waterwatch has been a great way to find out what actually is swimming or floating under the river’s surface. Previously we could only guess, but now I know the phosphate, nitrate and dissolved oxygen levels, turbidity, electrical conductivity and ph.During the first year I was collecting data it rained a lot, the river levels were high and the readings were very clean. Since last year however, the river has been mostly low, and the nitrate levels are generally off the charts high. Continue reading

This year the grand finale of our tree linkage project was not even on our own land. To complete the 3.9 kilometres (2.4 miles) of small plots that will allow birds like diamond firetails (stagonopleura guttata) and speckled warblers (chthonicola sagittata) to move around the landscape, we planted a larger area at the edge of the Dog Trap Road. A paddock that actually belongs to our neighbour Suzanne.
I now have a wonderful kit that will tell me what’s in the water that flows past our house.
Finally, we have some way to tell what’s going on underwater, other than just admiring clear water rippling over rocks. Or staring at turbid brown floodwater, with the occasional tree or wombat carcass floating by, while hoping that we’ll soon be able to get across.
