Copperlode Falls Dam or Lake Morris is a fresh water reservoir dam at Lamb Range, Cairns Region, Queensland, Australia,[1] servicing the city of Cairns.

[2] The reservoir is named Lake Morris after Cairns City engineer Frank Roland Morris who discovered its site,[3] but the dam itself is named after the waterfalls it replaced - Copperlode Falls.

It was evident to even the earliest settlers that a larger source of water would need to be secured as Cairns grew.

In 1935, he found a site at Copperlode falls, near the headwaters of Freshwater Creek, that he thought would be suitable.

The State Government originally set aside A$3 million for the dam, but by the time the dam was completed on 25 March 1976, the total cost had risen to approximately $6.5 million.
