Summary of progress

The Blackrock Creek catchment headwaters originate in the Clarke Range and High Ecological Value forest of Eungulla National Park before entering the coastal plain and estuary at St Helens Bay. Forty seven percent of the lowland are utilised for grazing, while 30% has been developed for cane production that is concentrated on the creek flats. The coastal zone is dominated by grazing to the estuary margins.

In 2007, Blackrock Creek and its’ estuary were rated as being in moderate condition relative to other catchment areas in the Mackay Whitsunday region. At this time, St Helens Bay was considered to be at high marine risk from reduced water quality and ecosystem health degradation. Between 2007 and 2013, there have been excellent commitment by farmers in the Blackrock Creek catchment to improve their on-farm management practices to improve water quality entering the receiving waters of St Helens Bay.

 

Future priorities

Grazing management practices that reduce phosphorus and nitrogen loads are the highest priority for continued improvement of event water quality in the Blackrock Creek catchment area. Management practices that reduce other nutrients and residual herbicides are a moderate priority.

System repair actions that restore riparian vegetation, saltmarshes and mangroves, and improve riparian connectivity are of the highest priority to improve the ecosystem health of the important estuarine areas at Blackrock Creek and St Helens Bay.
