❓ The WA parliamentary question concerns the review, publication, and continuation of oxygenation trials in the Swan and Canning Rivers. The response indicates trials were reviewed and published, with oxygenation continuing on the Canning River but not the Swan River due to scalability issues.

(b) has a review of the trials and their results been conducted; (c) have these results been tabled or published; and (d) is ‘oxygenation’ of the Swan and Canning Rivers to continue?
(c) have these results been tabled or published; and (d) is ‘oxygenation’ of the Swan and Canning Rivers to continue?
(d) is ‘oxygenation’ of the Swan and Canning Rivers to continue?
(b) A review of both trials and their results has been conducted. Both trials were comprehensively monitored. After the field component of the project was completed, the data acquired was reviewed and then reported on. (c) The results of both trials have been published. A number of publications detailing the results of these trials are available: Greenop B., Lovatt K. and Robb M.. 2001.

Following the successful oxygenation trial on the Canning River in 1998/1999, oxygenation has continued on an annual basis. Since the extension of the length of river oxygenated to 2.3km in December 1999, oxygenation has generally occurred from November to the end of April. Oxygenation of the Swan River was not continued, due to the scale of operation required to effectively increase oxygen concentrations over the middle and upper estuary.

(a) Oxygenation trials in the Swan and Canning River system have been completed. In the Canning River oxygenation trials, a prototype oxygenation plant successfully oxygenated one kilometre of the Canning River upstream of the Kent St Weir from November 1998 to April 1999. A prototype mobile oxygenation plant was used to oxygenate sections of the Swan Estuary in the summers of 1999/2000 and 2000/2001.
(b) A review of both trials and their results has been conducted. Both trials were comprehensively monitored. After the field component of the project was completed, the data acquired was reviewed and then reported on.
(c) The results of both trials have been published. A number of publications detailing the results of these trials are available:

(d) Oxygenation has continued on the Canning River but not on the Swan River. Following the successful oxygenation trial on the Canning River in 1998/1999, oxygenation has continued on an annual basis. Since the extension of the length of river oxygenated to 2.3km in December 1999, oxygenation has generally occurred from November to the end of April. Oxygenation of the Swan River was not continued, due to the scale of operation required to effectively increase oxygen concentrations over the middle and upper estuary.
