One of the 2 largest and most sacred lakes on the island. Both Kaboora and Bummiera are acknowledged as being the home of an extraordinarily huge carpet snake - jargon snake spirit yuri Kabool. It's spirit resides in both lakes with the jargon attributed with being able to travel from one lake to another. The old Quandamooka people cationed those that swam and skied on the lakes, so sacred were these lakes that old people would not approach them without a special acknowledgement. Many visitors go into these areas without a thought, but traditionally these lakes were approached with a sense of reverence, cation, respect and even fear. The Elders would always sing out in lingo before they went any further, standing back a fair way to see if there was a sign, before approaching closer to the lakes. If the waters were calm it was a sign that it was okay to proceed, but if there were any ripples or disturbance, it was a warning from jargon not to come any further. To the community, it was a ritual to stop, call out and observe, and the practice gave acknowledgement and respect to the lakes and yuri Kabool that lived there.From Quandamooka Dreaming, by Sandra Delany
