Lake Alexander at East Point has been temporarily closed to swimmers due to the detection of an isolated area showing elevated bacteria levels.
The elevated bacteria levels were detected during routine water quality monitoring.
City of Darwin conducts regular water quality monitoring to ensure public safety.
It is not unusual for high bacteria levels to occur in Lake Alexander during the Wet season. Recent rains have washed nutrients into the lake and this, together with sunny periods, has reduced water quality in the lake.
Flushing the lake with natural sea water is the best environmental action and this will mean the lake will be ready for swimmers in a matter of days.
City of Darwin is committed to maintaining the highest environmental practices to protect the community and our environment.
The public will be advised when the lake reopens, and people are asked to heed the closure signs until water testing is completed.
City of Darwin apologises for any inconvenience.
