Lake Julius
The dam is unique in Queensland and is a concrete multiple arch and buttress type structure, with the spillway discharging over the tops of the arches. The spillway crest is 18.3 m (60 ft) above bed level. The arch barrels, founded on a triangular arch base, are constructed in independent arch rings and are hinged at buttress springing lines. The spillway is a precast superstructure and the dissipation slab at ground level is post tensioned to the foundation rock.
The dam has had operational volumes ranging between a low of 59.22%, recorded on 24th November 2014, and a high of 169.73%, recorded on 15th January, 2004. The high being due to record breaking rainfall upstream in the Mt. Isa area.
SunWater is undertaking a dam spillway capacity upgrade program.
