Why doesn’t the Mount Isa Water Board control blue-green algae in the lakes?

Blue-green algae activity is intermittent and influenced by weather. There are no sure, cost-effective methods that can be used to effectively and safely control the development of blue-green algae in Clear Water Lagoon, Lake Julius or Lake Moondarra. This is a challenge faced by many water authorities throughout Australia.

Has there been a change the rules in respect to camping on the Reserve?

No. A this stage camping on the Reserve continues to be prohibited unless MIWB has expressly granted permission (as we do during the Moondarra Fishing Classic).

Notwithstanding this, MIWB understands that the R48 Reserve is important to the local community and that there may be community support for reviewing how permits are issued and the conditions under which camping could be made more generally permissible. It is also an opportunity for MIWB to understand if it needs to put in place more appropriate administrative mechanisms related to camping permit provision and management.
