The Upper Burdekin sub-catchment drains the western side of the coastal ranges and the eastern side of the Great Dividing Range and forms the northern reaches of the catchment. The coastal ranges consist of rugged mountains, hills and dissected plateaux of granite, and granodirorite, with the eastern side of the Great Dividing Range comprised of young basalt plateaux, high plains and rugged hills of volcanic and sedimentary origin.

There are extensive areas of moderately productive and fairly erodible red duplex soils. Highly productive black and red soils are widespread on basalt areas. The remaining areas of the catchment support poor to moderate fertility sands, sodic duplex soils, red and yellow earths. Intense weathering means that with the exception of the younger soils derived from basalt; nitrogen fertility and organic matter content are low.

Beef cattle grazing on rangelands is the major land use, accounting for over 90% of the sub-catchment. The other agricultural uses include irrigated pastures and horticulture (Roth et al. 2002). Nature conservation is the other major land use, with parts of several reserves being included within the sub-catchment.

Subcatchments

Smaller Catchments within the Upper Burdekin River Catchment include:

Vegetation

Based on the iTRARC analysis this catchment was in excellent condition in the 1970s and remains in a very good condition in 2004, with a small amount of floodplain clearing the only change. The TRARC field survey results indicate poor riparian condition in 10 of the 16 sites visited, with the remainder in good condition. The TRARC results provide valuable insight into the amount of regeneration and weeds that remote sensing cannot detect.

Wetlands

This sub-division includes an inland floodplain of the Burdekin River at the Valley of Lagoons, several large off-channel lakes, and a major basalt feature with numerous springs emanating from many locations that drives permanent flow and clearwater waterholes in many creeks. This creates not only many significant waterbodies but a wide variety of wetland types. Condition of all waterbodies is generally considered to be relatively good and several of the wetland habitats here are listed in the Directory of Important Wetlands.

SedNet Modelling

The following statistics are summarized from the CSIRO report: Improved SedNet Modelling of Grazng Lands in the Burdekin Catchment by Kinsey-Henderson, A., Sherman, B. and Bartley, R. 2007.

This report can be accessed from the report section below.

  • Sub-catchment area: 4,422 sq. km.
  • Source contributions: Hillslope = 65%; Gully = 24%; Streambank = 11%
  • Area of sub-catchment with <50% ground cover: 479 sq. km or 11% of sub-catchment
  • Hillslope sediment supply: 240 kg/ha/yr
  • Total suspended sediment (flow weighted) supply: 167 kt/yr (?)
  • Total suspended sediment end-of-subcatchment (flow weighted) yield: ? kt/yr
  • Event Mean Concentration (EMC - flow weighted): 280 mg/l
