Ewens Ponds

Ewens Ponds is a series of three water-filled limestone sinkholes located in the Limestone Coast region of South Australia. The ponds are renowned for their crystal-clear waters and unique underwater environment, making them a popular destination for scuba diving and snorkeling.

Location

Ewens Ponds is situated approximately 25 kilometers south of Mount Gambier, near the town of Eight Mile Creek. The ponds are part of the larger Ewens Ponds Conservation Park, which encompasses a total area of 85 hectares.

Formation

The ponds were formed through a process known as karstification, where the dissolution of soluble rocks such as limestone, dolomite, and gypsum leads to the formation of underground drainage systems with sinkholes and caves. The three ponds are interconnected by shallow channels and have a combined depth of approximately 10 meters.

Flora and Fauna

Ewens Ponds is home to a diverse range of flora and fauna. The clear waters of the ponds support a variety of aquatic plants, including the rare Short-leaf Water Starwort and Floating Pondweed. The ponds are also home to several species of fish, such as the Dwarf Galaxias and the Congolli, as well as a variety of invertebrates.

Conservation

Ewens Ponds Conservation Park was established in 1976 to protect the unique karst features and the associated aquatic ecosystems of the ponds. The park is managed by the Department for Environment and Water.

Recreation

Ewens Ponds is a popular site for snorkeling and scuba diving due to the clear waters and the unique underwater landscape. Divers can follow a marked trail through the ponds and the connecting channels, providing a unique opportunity to observe the aquatic life and the karst features up close.
