Gibson Creek Dam

Dam wall lift

Year: 2016

Location: Proserpine, Whitsunday, QLD

Client: Wilma Sugar

Specs: 10 metre wall height, 850 megalitres dam capacity, 20 metre wide spillway


Our client, Wilma Sugar, sought to improve water security whilst ensuring continued water supplies to sugar cane crops south of Proserpine.

Premise was engaged to design a dam wall lift (from the previous 6 metres to a significant 10 meter height), arrange all approvals, and supervise construction of the 850 megalitre dam.

Our unique design solution included a 20 metre wide spillway blasted into surrounding hillside –simplifying operation and ongoing maintenance. This design proved sound during recent rain events in the wake of North Queensland’s Cyclone Debbie.

In delivering changes to Gibson Creek Dam, Premise successfully accommodated the client’s rigorous design brief and budgetary requirements.
