The Western Catchments

Melbourne Water is responsible for the total area of the western catchments, about 4700 sq kilometres. This includes the Werribee, Kororoit and Maribyrnong catchments.

Dandenong Catchments

South-east of Melbourne lies the Dandenong Valley. This catchment has an area of 855 square kilometres, with some 485 kilometres of rivers and creeks that originally drained to a large coastal wetland, the Carrum Carrum Swamp.

Port Phillip Bay

Port Phillip Bay is a major economic, environmental and recreational asset for Victorians. Melbourne Water aims to improve the health and amenity of Port Phillip Bay for the prosperity and enjoyment of present and future generations.

We build wetlands throughout Melbourne to ensure that stormwater is treated before it enters the bay. As Melbourne's population increases, so too does the importance of efficient and effective programs to reduce litter and nitrogen from flowing into the bay.

The Yarra Catchments

The Yarra River begins on the southern slopes of the Great Dividing Range, in the forested water supply catchments of the Yarra Ranges National Park. Although the Yarra River is not large by Australian standards, it is a very productive catchment as it generates the fourth highest yield of water per hectare of catchment in Victoria.

Western Port Bay

Western Port relies on a healthy marine environment to sustain a range of recreational and tourist activities. Melbourne Water is responsible for managing the streams that enter Western Port. Our aim is to minimise the impact of these waterways to help manage Western Port in a sustainable manner.

Westernport and Mornington Peninsula Catchments

The Westernport catchment has an area of 3433 square kilometres and some 2232 kilometres of rivers and creeks. Average annual rainfall ranges from 750mm along the coast to 1200mm in the northern highlands. Approximately 70% of the catchment is rural land, 20% is Crown land and five per cent is urban.
