The National Capital Authority (NCA) has issued an Extreme
Alert Level for blue-green algae in East Basin, Lotus Bay and
Yarralumla Beach in Lake Burley Griffin.
Secondary-contact (such as rowing, fishing, boating and
canoeing) will still be permitted, however people should
not engage in secondary-contact recreation unless:

* they are experienced;

* they are informed of the algae risks and what to do if
contact occurs;

* they do not engage in primary-contact during the
recreation; and

* shower facilities, with suitable water, are available
for washing after the recreation.

In particular, contact with algal scum should be
avoided.  Clothing that has been in the water should
be washed to remove any blue-green algae residue.
Water event organisers should ensure all participants are
aware of the blue-green algae alert level, the associated
exposure risks, and provide adequate shower
facilities. A media release can be found here and further information at the
NCA website.
