It looks like we can now use the water at Molonglo Reach.  The ski area is classed as medium level of infestation (ACT Govt) and all of Lake Burley Griffin is open to all activities (NCA readings). 

This week's reading states that the Molonglo Ski Area is still at "Medium". 

But Lake Burley Griffin is now to all uses. 

 Meanwhile, for the rest of the lakes in the ACT: Lake Ginninderra and Lake Tuggeranong are both now "medium" counts which means they are okay for paddling on - but not swimming in.

Yerrabi Pond, Gungahlin Pond and Point Hut Pond are open to all uses.
