The City of Canning’s waterways provide an environment for rest and recreational activities both in and around the water which can benefit health and wellbeing.

However, there are also potential hazards when using recreational water.

To make sure waterways are safe to swim in, the City’s Environmental Health Officers undertake regular bacterial testing at a variety of popular Canning River locations during the months of November to April, when people are more likely to swim.

We do this to determine trends in water quality and contribute to the Department of Health’s state-wide classification system for recreational water bodies such as beaches and rivers to help you decide where you want to swim.

The City’s Environmental Health Officers also work to contribute to the Department of Health’s state-wide classification system for recreational water bodies to help you decide where you want to swim. They issue warnings during pollution events by use of signage and via social media, identifying bacterial pollution sources and looking for long-term bacterial trends.

Advice for swimming in the Canning River

There are some basic rules that can be followed to reduce your risk of exposure to bacteria and other organisms when swimming in the Canning River;

  • Avoid swimming after heavy rainfall (greater than 10 mm). This is due to storm water finding its way into the river system bringing with it organic matter from drains;
  • Avoid swallowing water or putting your head under water if you are unsure about its quality;
  • Avoid swimming if you have an open wound or infection.

Microalgae Activity Report

The Microalgae Activity Report (MAR) is a weekly report, produced by the Department of Parks and Wildlife, which informs the public on microalgae levels and the probability of discolouration and/or scum formation at sites throughout the Swan Canning estuary. For more information on the report, click here. The MAR is updated on the website on Friday and in the weather page of The West Australian newspaper the following Monday. From time to time, there are warnings issued to avoid the water during high algal activity.
