VIC DELWP - Catchment Management Authority - Boundaries (Polygons)

This layer presents the footprint of Catchment Management Authority (CMA) boundaries (derived from CALP100). The CMAs were established on 1 July 1997 with the aim of creating a whole of catchment approach to natural resource management in the state. The new CMAs combined the roles of the former, River Management Boards and Catchment and Land Protection Boards, and community based advisory groups such as salinity plan implementation groups and water quality working groups. The data is accurate to +/- 100 metres for 80% of the time.
