The Goulburn-Broken CMA Region is situated in north central Victoria where it extends from near Woods Point in the Great Dividing Range to the Murray riverine plains in the north-west (near Echuca). The region has two river basins, the Goulburn River and Broken River.
Generally, the catchment experiences a warm temperate climate, with hot and relatively dry summers, and cool wet winters. Seasonal patterns show a marked winter rainfall incidence, with June typically the wettest month. Average annual rainfall ranges from less than 500 mm in the far north of the region to more than 1600 mm in the high country in the south.
Most of the catchment has been cleared for agriculture with intensive irrigation in the north and dryland farming enterprises in the south, such as sheep and cattle grazing, wool, wheat, barley and oat production.
Dryland salinity is one of the major natural resource management issues facing the middle parts of the catchment and threatens land, water and environmental assets in several sub-catchments (e.g. Kurkurac Creek, Dry Creek, Majors Creek, Whiteheads Creek, Sheep Pen Creek and Honeysuckle Creek). Dryland salinity is widespread with more than 720 individually mapped units1 recorded as saline with the approximate total area of 4670 hectares1 .
High watertables and salinity associated with irrigation development also threaten productivity and environmental values across the irrigated parts of the northern riverine plains. Dryland salinity is responsible for high salt loads feeding into some mid-catchment streams and is a major contributor to water quality and stream degradation in the River Murray system.
The region has a range of local, intermediate and regional Groundwater Flow Systems (GFS). Each of these GFS presents unique salinity problems. For better monitoring and reporting of salinity risk, 17 Salinity Provinces have been defined in the region, nine of which are High priority.
The Goulburn Broken CMA has an extensive range of online materials (maps and documents etc.) which outline the biophysical assets of the catchment, as well as their major risks (including soil and water salinity). This material also outlines the programs and projects currently being completed by the CMA to protect and enhance these assets. An example of this is the Goulburn Broken CMA ‘Published Documents’ resource, the link to which can be found at the base of this page.
