Yerrabi Pond—water quality
(Question No 668)
Ms Castley asked the Minister for Water, Energy and Emissions Reduction, upon notice, on 25 March 2022:
(1) How many complaints has Transport Canberra and City Services had about water quality at Yerrabi pond since 2016.
(2) What has the Government done since 2016 to reduce Blue Green Algae blooms at Yerrabi Pond and will the Minister provide a breakdown of money that has been spent so far on these activities.
(3) What work does the Government plan to do to reduce Blue Green Algae blooms at Yerrabi Pond and will the Minister provide a breakdown of future activities and their estimated cost.
(4) What testing has the Government conducted for water quality at Yerrabi Pond since 2016.
(5) What reports has the Government produced about the water quality of Yerrabi Pond since 2016 and can the Minister provide these reports.
(6) Are these reports or test results publicly available; if not, why not.
(7) Is the Government planning to build a floating wetland at Yerrabi Pond; if not, why not; if so, what is the process and timeframe and when will the wetland be finished.
(8) What work has the Government done about establishing a floating wetland at Yerrabi Pond.
Mr Rattenbury: The answer to the member’s question is as follows:
1) TCCS Fix My Street returned no complaints specific to the water quality of Yerrabi Pond.
2) Yerrabi Pond experiences strong growth of the submerged macrophyte Vallisneria (‘ribbonweed’) and filamentous algae attaches to this. These growths indicate that Yerrabi Pond is nutrient enriched, as expected since it is part of the pollution control system for Gungahlin. However, Yerrabi is not as susceptible to blooms of blue-green algae as are some other lakes and ponds in the ACT, likely because of the protection afforded by the Vallisneria, which competes with algae. The ACT Government is investing in a floating wetland for Yerrabi Pond that will help control nutrient levels and thus algal growth. The cost of the floating wetland is in the vicinity of $600K.
