Paralana Hot Springs

While weathering and seasonal rains can cause waterholes at to silt up, Paralana Hot Springs continue to flow as a shallow stream. Sourced from within a fault zone, the water is around 60 degrees and emits gases such as radon which is heavier than air and hovers around the creek area on still days. A wonderful array of Cyanobacteria, Proteobacteria and algae thrive in the Paralana Hot Springs.

Filamentous Green Algae: Retention Dam

Threadlike filamentous green algae growing in the shallows of Copley Retention Dam. These soft strands consist of a chain of cells, giving a thread-like appearance. Oxygen production as a by-product of underwater photosynthesis creates buoyancy, causing the strands to incline toward the surface.
