Algae alert for Lake Ginninderra

Released 01/11/2016

Access Canberra has issued a medium alert level for Tychonema algae in Lake Ginninderra.

This action has been taken in accordance with the ACT Guidelines for Recreational Water Quality following advice from ACT Health.

Where possible, people using this water for recreation should shower as soon as practicable after leaving the water to remove algae from the skin. Clothing or swimwear that has been in algae-affected water should also be thoroughly washed to remove any algae residue.

Young children are particularly vulnerable to Tychonema algae exposure as they are more likely to swallow water during recreation. Parents/guardians should monitor children closely and discourage submersion of the face or head to limit Tychonema algae exposure.

Pet owners should not allow their animals to swim in or drink the water, as pets are much more susceptible to Tychonema algae than humans and exposure can make pets very ill or even result in death.

Water event organisers should ensure all participants are aware of the Tychonema algae Alert Level, the associated exposure risks and provide adequate shower facilities.

Lake Ginninderra will be re-tested in a week, as algae levels can change quickly. Water users should look for algae warnings signs which indicate the current algae alert level. Warning signs are located at public access areas.
