Healthy Waterways Strategy

The draft Strategy is intended that stakeholders and the community are involved in waterway management or activities that may affect waterway condition. The draft Healthy Waterways Strategy considers the needs of Port Phillip Bay and Western Port. This draft Strategy includes water quality targets to protect the health of the bays. Eight major streams enter the bay. Yarra is the largest freshwater inflow.

The Yarra River

Yarra River and its major tributaries flow through forested, mountainous areas reserved for water supply purposes. The catchment includes major water storages and numerous farm dams, and waterway diversions for agriculture. Flows in the Yarra River and many

  • f its tributaries have been

changed significantly. This means it is necessary to actively manage how water flows through them. These flows are called ‘water for the environment”.

Yarra River Outcomes

Evolving role of environmental flows Natural events are the main flow events Since managing the releases from 2011 we have seen:

  • Improved water quality during releases
  • Enhanced ecology

Waterways focus

Understanding characteristics of events key to health

  • Science- location, triggers, migration
  • Frequency, and flow rates
  • Rate of rise, and duration
  • Pre event conditions
  • Drought influences

Future opportunities

  • Natural ecosystems are complex.
  • Continuous learning and improved understanding of species,

impacts from current and future challenges, community expectations.

  • Engaged Fishing community.

To have a healthy waterways and bays we all have a role to play.
