  • THIS WAS RETIRED AND REPLACED BY SWSCA100 ON 08 SEPTEMBER 2023. Formerly Proclaimed Water Supply Catchments. Domestic Water Supply Catchments as proclaimed under the Soil Conservation and Land Utilization Act, 1958 in conjunction with the Land Conservation Act, 1970. This layer identifies domestic Water Supply Catchments that are subject to a Land Use Determination or a Land Use Notice.

  • This layer represents the Catchment Management Authority (CMA) boundaries (derived from CALP100). It is indicative and should not be used for operational decisions about funding. The CMAs were established on 1 July 1997 under the Catchment and Land Protection Act 1994 (CaLP Act) to create a whole catchment approach to natural resource management in Victoria. The CMAs combined the roles of the former, River Management Boards and CaLP Boards, and community-based advisory groups such as salinity plan implementation groups and water quality working groups. The 2014 correction was on the West Gippsland and East Gippsland CMAs border around the Gippsland Lakes. The 2021 amendment was a realignment between the Melbourne Water boundary and surrounding CaLP regions. These boundaries now align with the waterway management district boundaries for Melbourne Water and surrounding CaLP regions. This followed an amalgamation of the Port Phillip and Westernport CMA with Melbourne Water as a new authority administering the Port Phillip and Westernport CaLP region in December 2021. It is accurate to +/- 100 metres for 80% of the time.
