Dimboola, Victoria, isn't exactly known for its subtlety, but its hidden treasures sometimes require a bit of seeking out. Loch Iel Lake Reserve, or Pink Lake as the locals call it, is one such treasure.

Now, we've seen pink lakes before, but the science behind this one is quite interesting. The signage explains it's all down to a combination of algae, halobacteria, and specific carotenoid pigments that thrive in the super-salty conditions.

The pink color itself depends on the algae, and the salt. It only appears during periods when the water is at the exact right depth and salinity. It's interesting, but sometimes a little underwhelming.

The reserve's informational signage tells us about the lake's ecological importance and the traditional owners' connection to the land. These places are culturally significant and are being protected. It's a good reminder to respect the land and its history. You have to give it to them; they do a good job.
