As the rain continues to fall in southern Tasmania, flooding roads and inundating homes, the downpour has caused one of Hobart's most mysterious gems to reappear.
Hidden away on kunanyi/Mount Wellington, the crystal clear waters of the Disappearing Tarn are back.
A local hiker, Jemina Stuart-Smith, made the early morning trek up the mountain to see the phenomenon.
"There's a dip in the rocks and it fills up with this water, it's a really deep blue or bright blue colour," she said
"It's engulfed a couple of trees that sit in the middle.
"It's a pretty backdrop and it's really clear, blue water so it's quite beautiful."
Only avid bushwalkers know where to find the tarn's secret location.
Ms Stuart-Smith said she first heard about the Disappearing Tarn about four years ago.
"I've been in 10 times and it's only been there four of those times and I've tended to go after lots of rainfall to try and time it, but it's just hard to get right," she said.
"We started the walk at The Springs, which is four kilometres from the bottom of the mountain, and driving up along the road there were patches that were flooded with water.
"There was tons of water coming down off the mountain, so we kind of thought that we would be in with a good chance [of seeing it], but you can never tell."
The small mountain lake has become a sought-after location amongst social media snappers and serious photographers.
Bureau of Meteorology forecaster Michael Conway said more than 200 millimetres had fallen on the mountain over the past three days.
"It's very wet up on the mountain," he said.
"It will still keep ticking over, the weather that's been bringing all the rain is slowly moving up towards the north east as a low pressure system moves past Flinders Island, and that's dragging all the rain with it."
A sign that the tarn's clock is once again ticking.
