On my travels around Australia and New Zealand I have noticed that the colours of the rivers lakes and seas can change dramatically from place to place.
Lake Pedder, Tasmania colour due to tannins in the water
Hutt Lagoon, Western Australia colour due to beta carotene trapped in the salt
River near Bicheno, Tasmania
Little Blue Lake, North East Tasmania the lake was once a tin mine the water is highly toxic
Dam, Central Australia
Like the Remarkable Rocks thread I though that this would be a good opportunity to see what the rest of the world looks like. So show us what water looks like around the world.
