Water resources - Overview - Queensland
Groundwater Management Unit: Logan / Albert Rivers
Introduction
The Logan and Albert Rivers groundwater management unit (GMU) is located about 20km south of Brisbane in south-east Queensland and has an area of approximately 1325 sq km. The GMU is within the Logan-Albert Rivers Basin in sub-basins 1450 and 1451 respectively.
Groundwater supply in the Logan and Albert Rivers GMU is present in deposits of unconsolidated Quaternary alluvium associated with the Logan and Albert River valleys. Average thickness of the fluvial deposits is around 25 m. These cut into Jurassic sandstone bedrock and are overlain by a confining/semi- confining layer of clay and silt. The sustainable groundwater yield in the GMU is estimated to be 13950 Ml/yr at supply rates of up to 25 l/s.
The Logan and Albert Rivers GMU has a sub-humid, sub-tropical climate experiencing long hot summers and relatively short mild winters. Average annual rainfall is about 910 mm and is often associated with storms of high intensity and short duration. About 70% of the annual rain falls between October and March.
Groundwater use is estimated to be around 11000 Ml/yr. The water is of good quality and used as a primary source of irrigation and private domestic farm supply. Town water supplies are met by surface water supplies.
