Summary of progress
The Thompson Creek catchment area includes the Nationally Significant Goorganga Plains Wetland Complex. This seasonal wetland covers more than 16,000 hectares and is habitat for a diversity of significant flora and fauna as well as providing a nursery for recreational and commercial fisheries. Beyond the wetlands almost 40% of the catchment supports grazing with an additional 10% under cane production.
In 2007, Thompson Creek catchment area and estuary was rated as being in moderate condition. Between 2007 and 2013, there have been efforts by local farmers to improve management practices to benefit water quality leaving farms and flowing downstream to enter the High Ecological Value and Declared Fish Habitat Area of Repulse Bay.
Grazing and cane management practices that reduce reactive phophorus and dissolved nitrogen loads are the highest priority for continued improvement of event water quality. Management practices that reduce other nutrients and residual herbicides are also a priority.
Highest priority system repair actions should be planned to improve flow in wetland areas, restore mangroves and saltmarsh for fishery productivity and remove instream barriers. Restoration of instream habitat to support improved bed and bank stability are also important future activities for the ecological health of the catchment.
