Melbourne's Catchments

Melbourne is one of only a few cities in the world which has such large protected catchments.

These catchment areas, operated by Melbourne Water, contain more than 150,000 hectares of natural eucalypt forest with a large proportion reserved, for more than 100 years, solely for the purpose of harvesting water.

In these catchments and the major reservoirs associated with them, public access, recreational use and any activities which could adversely affect water quality are restricted.
