Lake Alexander at East Point Reserve has been temporarily closed today after high bacteria levels were detected during routine water quality monitoring.
City of Darwin Chief Executive Officer Scott Waters said it was not unusual for monsoonal rain events to result in high bacteria levels.
"Water testing conducted this week show bacteria concentrations are above recommended levels, which is often the case after the recent significant rain events," Mr Waters said.
"The safest course of action is to keep the lake closed to all water activities until the levels have normalised."
Water quality at Lake Alexander is regularly monitored for public safety. The most recent test results have yielded high Enterococci at sample sites in the lake. The lake will continue to be tested daily.
"City of Darwin is committed to maintaining the highest environmental practices to protect the community and our environment," Mr Waters added.
The public will be advised when the lake is reopened. Until then please heed all signs.
The wet conditions have also led to the closure of some walking and bike trails at East Point due to safety concerns around damage caused due to the ongoing rainfall.
Repairs will be conducted to the trails once dry conditions allow machinery to access and repair the damaged sites to then reopen for public use.
Council apologises for any inconvenience.
