About impact reports

An underground water impact report (UWIR) identifies bores in a long-term affected area (LAA) that are predicted at any time in the future to exceed the bore trigger threshold:

  • a 5 metre decline in water level for a consolidated aquifer;
  • a 2 metre decline in water level for an unconsolidated aquifer; or 
  • a threshold set by regulation.

It also identifies bores in a subset of the LAA, called the immediately affected area (IAA), that are predicted to exceed the bore trigger thresholds within the next three years.

In the case where there are multiple petroleum tenures, with more than one tenure holder, adjacent to each other, the chief executive responsible for administering Chapter 3 of the Water Act 2000 may declare a cumulative management area (CMA).

To date, only one CMA has been declared in Queensland, and that's the Surat Cumulative Management Area (see map below). The Office of Groundwater Impact Assessment (OGIA) is the statutory government body responsible for preparing and updating the UWIR for the Surat CMA.

The bores identified in the IAA, as well as any bores for which a bore assessment has been directed by the chief executive under section 418 of the Water Act 2000, are bores to which the make good process applies.
