The National Capital Authority has announced they’re re-opened the lake for all uses:
Although bacteria has returned to a safe level, lake users are advised to be alert to the presence of hazards such as logs and debris which have entered the lake as a result of the flooding. These hazards may be partially or completely submerged. The NCA urges users to exercise caution and to assess risk levels before entering the water.
The Captain Cook Memorial Jet will remain non-operational until flood debris is cleared.
Ongoing advice from ACT Health is that swimming should be avoided for several days after heavy rainfall as bacteria can be strongly influenced by such events.
