The Disappearing Tarn is a fascinating example of how geological features, rainfall patterns, and environmental factors interact to create a transient natural wonder.
This ephemeral lake forms when heavy rains fill a rocky depression, creating a temporary pool with stunning turquoise waters. Its brief existence,
lasting days to weeks, is due to the porous rock surrounding it, which swiftly drains away the water once rainfall diminishes. Located in Hobart’s drinking water catchment, strict regulations prohibit swimming to safeguard water purity.
Its periodic appearance and disappearance highlight the delicate balance of nature and the resilience of ecosystems in responding to natural fluctuations.
Those caught in the act of swimming can expect immediate on-the-spot fines of $202, and fines can soar up to $4,040 per offense if the case reaches the court
