Griffith City Council announced on Monday, January 11 that Lake Wyangan (North) was on red alert.
Sampling will be carried out twice weekly until two consecutive results are below 10 mm3/litre biovolume.
Results from 5 January show a total biovolume of 26.920 mm3/litre.
A red alert level warning indicates that people should not undertake recreational activities where they may be coming into direct contact with the water such as swimming, as well as domestic uses including showering and washing.
IN OTHER NEWS:
Contact with the water may also pose a threat to livestock and pets.
Warning signs are positioned at key recreational areas and will remain in place while high levels of blue-green algae are present.
People are advised not to enter the water, drink untreated water or bathe in water drawn from the lake while this red alert level warning is in place.
Town water supplies remain unaffected and safe to drink.
Before consumption, any fish caught should be cleaned and washed thoroughly in uncontaminated water and any internal organs disposed of appropriately.
Council said it was not possible to predict how long the algae will remain at high levels.
Regular monitoring will continue and the alert will be lifted as soon as the high levels of algae dissipate.
Just before Christmas council announced blue-green algae levels at Lake Wyangan had been downgraded to an amber alert, meaning boating and fishing were both permitted, but swimming was not.
A further 800 megalitres of water was also added to the lake before Christmas.
