[1][2] The swamp developed in a former lake basin, as it was filled by an alluvial fan or deposits of water-transported material.

In addition, evidence of cultivation of bananas and sugar cane has been found, estimated to have begun 6,900 – 6,400 years ago.

The Kuk Creek flows through the entirety of the fan to a catchment in the lower hills of the south region.

Archaeological evidence for early agricultural drainage systems, dating back to about 9,000 years ago, has been found here.

Major disposal channels were constructed to divert water flowing south from the fan and direct it towards the northeast areas.

[3] Additional archaeobotanical evidence, dated to between 6,900 and 6,400 years ago, has been discovered showing the cultivation of bananas and sugar cane at Kuk Swamp.
