The colours of water

I have started to immerse colour negatives into the water collected when the photograph was made. Before I did this I photographed the water in the glass containers by itself. Water is transparent, but its surface reflects the surrounding light, enabling us to see reflections which mirror the surroundings. When the surface tension is broken by the water travelling over falls or around rocks, we can appreciate the colour of the water, which is largely caused by suspended particles being carried along by it.

The Yarra River – Birrarung is renowned for being a muddy brown colour as it flows through Melbourne – Naarm. This colour and the colour of the falls is caused by the presence of fine particles and sediment within the water. My water samples reflect this and the changing nature of the water as it flows down the river. The water samples are shown below, but I was fascinated how they change as you moved downstream:

The Source (a small stream) containing fine particles of organic (vegetation) matter in the foothills of Mt Baw Baw
Upper Yarra – the clearest water as it flows out of the dam, where the organic matter has settled out
Westerfolds – the water has travelled through agricultural land with run-off that has deposited fine sediments within it, turning it a brown colour
Bolin Bolin – the water here looks the “dirtiest” because it is from a Billabong (lagoon) that contains a large amount of decaying vegetation and organic matter.
Dights Falls – similar to Westerfolds
Victoria Dock – the water here is brackish (slightly salty) because it is a mixture of fresh and salt water. It’s interesting that when I poured it into the glass container, it was the only water to form bubbles that stuck to the sides of the container (which were still present the following day)
