Pink lake amazes from above

A Colac district pilot photographed Lake Weering, which appears pink due to algae that can survive in high-salinity lakes.

Bright colour changes to Colac district water bodies have captivated a pilot flying overhead.

Barwon Downs resident and recreational pilot John Callahan and his wife Catherine photographed the “bubble-gum pink” Lake Weering from their light aircraft on New Year’s Day.

The couple also photographed “sea sparkle” algae in waters between Lorne and Aireys Inlet.

Mr Callahan said the saltwater Lake Weering, south of Cressy, turned pink “practically every year” during warmer months, and was among other lakes in the district that regularly turned iridescent green or orange.

Parks Victoria area chief ranger Jessica Reed said the colour change occurred when the lakes reached a certain level of saltiness and reacted with algae.

“Though not occurring as frequently as at other locations, the phenomenon has been observed at Lake Weering from time to time,” Ms Reed said.

“This saltiness, combined with various species of algae, either generates secretions of red pigment into the water or the algae growing at the bottom creates an illusion.”

Victoria’s best known pink lakes are in the state’s north-west, including the 20,000-hectare Lake Tyrrell, which attracts visitors from around the world.
