Catchment management authorities
Integrated Catchment Management (ICM) is the coordinated management of land, water and biodiversity resources based on catchment areas. It incorporates environmental, economic and social considerations.
In Victoria, ICM underpins sustainable management of land and water resources, and contributes to biodiversity management. Victoria’s framework for the integrated management of catchments is established under the Catchment and Land Protection Act 1994 (the CaLP Act).
Victoria is divided into ten catchment and land protection regions, each reflecting the unique biophysical qualities of each area. In each region, a Catchment management authority (CMA) (Figure 3) is responsible for the integrated planning and coordination of land, water and biodiversity management. The exception is the Melbourne and Westernport region, in which Melbourne Water is responsible for these functions. CMAs and Melbourne Water work very closely with community, Traditional Owners and other local partners in their planning and management activities.
Under the Water Act 1989, catchment management authorities are also responsible for regional waterway, floodplain, drainage and environmental water reserve management. The 10 CMAs are:
Mallee
Wimmera
Glenelg Hopkins
Corangamite
Melbourne Water (formerly Port Phillip and Westernport CMA)
West Gippsland
East Gippsland
North East
Goulburn Broken
North Central.
