Water

Where does Couran Cove Resort's water come from?

South Stradbroke Island is a big pile of sand sticking out of the ocean. This pile sits on a solid rock base 40 metres below ground level. And it's full of fresh water.

Any rain that falls on the island filters slowly through the topsoil and sand, collecting in an enormous lens-shaped reservoir underground. This fresh water doesn't mix with the sea water beneath it, but spreads out to form a water layer from the centre of the island to the east and west edges. On the eastern side of South Stradbroke, this water table lies very close to the surface. Depressions– in the ground fill up immediately with fresh water as at the site of the old sand refinery called Clayton's Lake.

The resort draws its water supply from this water– table.
