Lake Julius
Encyclopedia
Lake Julius was formed following the construction of Julius Dam in 1976 for irrigation and town water storage. The dam wall is located just below the junction of the Leichardt River and Paroo Creek some 70 km North East of Mount Isa. It has a full supply capacity of 127,000 ML, a surface area of 1,255 hectares with an average depth of 8.9 meters.
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 metres 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 a total storage capacity of 107,500 ML, and has a full supply level of 223.54m AHD
