Figure 1: The Goulburn Broken Catchment
This chapter summarises the Goulburn Broken Catchment’s biodiversity, land, water and people assets, including their values and condition. The supplement Assets of the Goulburn Broken Catchment provides further details.
The Goulburn Broken Catchment covers 2.4 million hectares, extending north from near the outskirts of Melbourne to the River Murray on the border with New South Wales (Figure 1). The Catchment boasts a diversity of landscapes, including seasonally snow-covered alps, forests, granitic outcrops, gentle sloping plains, box woodlands and red gum floodplains.
Average annual rainfall varies across the Catchment, from 1600 millimetres in the high country to 400 millimetres in the north-west (Bureau of Meteorology 2012). Two major river basins cover 2 per cent of the Murray-Darling Basin, or about 10.5 per cent of Victoria. Inflows to the Catchment are 3,559 gigalitres per year, or about 11 per cent of the total annual inflows to the Murray-Darling Basin (Murray Darling Basin Authority 2010).
