Another case of blue-green algae has been detected, this time in Nagambie Lakes.
Goulburn-Murray Water is urging people to avoid direct contact with water in the entire Nagambie Lakes system.
While Nagambie Lakes will not be closed to the public, warning signs will be positioned at major recreational areas around the lakes and will remain in place while high levels of blue-green algae are present.
If people come in contact with the algae, it could lead to skin rashes or itchiness; sore eyes, ears and nose; or if swallowed, nausea or vomiting and gastro.
This is not the first time Nagambie Lakes has had an algae outbreak.
A warning was previously issued on March 25 for Turner Island backwaters east and west, located near Kirwans Bridge, within the Nagambie Lakes.
G-MW said the blue-green algae detected in the remaining Nagambie Lakes was a different species of algae and therefore this natural event had occurred independently.
