Overview
Ewens Ponds offers a unique freshwater diving experience in South Australia. Known for its exceptional clarity and abundant aquatic plant life, divers can explore a series of three main ponds connected by shallow, flowing channels. The site features intricate limestone formations and a diverse array of freshwater species. Its crystal-clear waters provide excellent visibility.
Briefing note
Permits are required for diving at Ewens Ponds and must be obtained in advance. The site is a popular training location and can experience strong outflow, requiring controlled buoyancy. Entry and exit points are well-defined.

Sources & methodology
How we summarise this
We aggregate confirmed occurrence records from GBIF and OBIS within a fixed radius of each dive site. Occurrence records confirm presence and reveal seasonality clustering, but they DO NOT measure per-dive probability — there is no eligible-effort denominator. We deliberately do not publish a numeric '% chance of sighting' from this data.
