Features
The main feature of the park are the lakes, thought to have formed around 15 million years ago by geological activity, the land lifting and largely cutting them off from the local river system. Their outflow is reduced to the small Blue Gum Creek, which flows west into the Little River in the adjacent Nattai National Park to the west.
The lakes and their environs contain an unusual and diverse array of flora and fauna. It contains the rare freshwater sponge Radiospongilla sceptroides, and is notable for an absence of freshwater snails.
