What impact does blue-green algae have on the Reserve?

Some species of blue-green algae produce a toxin that can cause a reaction in susceptible people if it is swallowed or gets on the skin. Reactions include a rash, hayfever-like symptoms or stomach aches. The Mount Isa Water Board operates two blue-green algae information and indicator signs in the R48 Reserve to advise the public of the current blue-green algae risk.
