Aotearoa is home to the world's clearest freshwater - Rotomairewhenua/Blue Lake 💙
But with increasing numbers of visitors to this tapu (sacred) spot, the lake's pristine water is at risk from lindavia, a microscopic algae that can hitch a ride on tramping gear.
Lindavia causes a sticky, slimy material known as 'lake snot' to grow under the surface. Once it's present in the water, we can't get rid of it.
As you can imagine, lake snot would irreversibly spoil Rotomairewhenua's crystal-clear blue water. As visitors to this sacred spot, we're all responsible for protecting it.
