Auckland Council has advised that the testing of the water at the Lily Pond in Claude Abel Reserve has revealed that dissolved oxygen levels have dropped due to an increase in water temperature. The Council will be carrying out aeration of the pond for a period of two weeks, beginning 2 April ” 16 April 2013 .
The aeration breaks up the thermoclines and attempts to cool the water body, which increases the dissolved oxygen levels again. The levels are not dangerously low. Parks have been closely monitoring the pond and the works being carried out are proactive. Parks will continue to carrying out monitoring and expect the levels will improve when testing occurs again after aeration.
