Canning River oxygenation trail, Perth, Australia. Bubbles form on the surface from oxygen pumped into the river. Oxygen is released from submerged pipes and percolates up through the water, leaving a trail on the surface. This is necessary to alleviate anaerobic conditions exacerbated by low water volumes and algal blooms.

There are three oxygenation tanks on the banks of the Canning River between Nicholson Road bridge Kent Street Weir. Large black polythene tubes run from the tanks into the river, snaking there way downstream just below the water’s surface.
The Department of Water released a report in 2013 stating that anaerobic conditions existed in the river most times of the year. This means that the water is deprived of oxygen to support aquatic life.
The third oxygenation tank was completed in 2014. The Department’s report also highlighted elevated levels of toxins and reduced rainfall due to the drying of the climate.
It was reported that desalinated water via Perths desalination plants had also been pumped into the river to maintain it.
