Subcatchments

Smaller Catchments within the Townsville Catchment include:

Vegetation

Riparian Habitat

The following information is summarized from the ACTFR report: Assessing the condition of riparian vegetation in the Burdekin catchment using satellitte imagery and field surveys by Leo Lymburner and John Dowe. 2006. This report can be accessed from the report section below.

iTRARC analysis of Riparian Habitat idicates that the Townsville catchments have dropped from being in very good (A) condition to relatively poor (C+)condition in 2004. This is the result of clearing of vegetation along the main channel of the streams that drain these catchments combined with floodplain clearing.

SedNet Modelling of Water Quality

The following statistics are summarized from the CSIRO report: Improved SedNet Modelling of Grazing 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.

Model results for the Townsville subcatchment are summarized as follows:

  • Sub-catchment modelled area: 1,700 sq. km.
  • Source contributions: Hillslope = 55%; Gully = 4%; Streambank = 41%
  • Area of sub-catchment with <50% ground cover: 62 sq. km or 4% of sub-catchment
  • Hillslope sediment supply: 408 kg/ha/yr
  • Streambank sediment supply: 306 kg/ha/yr
  • Total suspended sediment (flow weighted) supply: 127 kt/yr
  • Total suspended sediment supply (flow weighted; normalized to area): 748kg/ha/yr
  • Total suspended sediment end-of-subcatchment (flow weighted) yield: 170 kt/yr
  • Event Mean Concentration (EMC - flow weighted): 447 mg/L
  • Mean Annual Flow: 380,853 ML

In summary, moderate to high mean annual flow (380,853 ML) together with moderate to high levels of total suspended sediments (127 kt/yr) result in low concentrations of sediments and associated nutrients (447 mg/L)in the Townsville Catchments. It is estimated that slightly over half of the sediments entering the waterways derive from hillslope erosion (55%), however a further 41% of sediments are the result of gully erosion providing 408 kg/ha/yr and 306 kg/ha/yr of sediment respectively. The model suggests that only a small proportion of the Townsville subcatchments have less than 50% ground cover.
