Pressures on the marine water quality of Port Phillip Bay

This page describes some of the main pressures on marine water quality in Port Phillip Bay.  They are barriers to achieving this strategy’s targets so planning and action will need to find ways to minimise their effects.

Whilst the condition assessment shows that the Port Phillip Bay’s water quality is generally good, pressures on water quality come from a variety of sources including the catchments, marine vessels and marine infrastructure.

The main sources of pollutants to marine water quality are from catchments, particularly from the Yarra River.  Climate change also creates pressures to Port Phillip Bay’s marine waters.

Much of the information about pressures has been sourced from the Baywide water quality monitoring program (Milestone report no.9, Port Phillip Bay water quality: November 2007 – December 2011, March 2012).

Water quality in Port Phillip Bay has been assessed (Method and Condition). Targets have been set (Targets) and lead organisations are committed to achieving the targets (Leadership). Arrangements are in place to monitor and report on progress and success (Monitoring and Reporting). Targets and leadership arrangements are determined in consultation with relevant departments, agencies and delegated land managers
