Red alerts remain in place for Blue-green algae on the Murray River at Mt Dispersion and the Murray River downstream from Mildura Marina to Wentworth.
Following recent results at Mildura, the red alert may be reduced if another low result is received next week.
Blooms have been reported for the Darling River at Menindee and Pooncarie.
Sampling was carried out on 6 April although those results are expected early next week.
