The acidity of the river water was tested at four different points:
Point 1- Close to the source of the Nulla Nulla Creek, just after it flows out of the Mason Ranges.
Point 4- Adjacent to the Rees residential development, just below the junction of Nulla Nulla and Magpie Creeks.
Point 6- Immediately downstream of the city of Dillon.
Point 8- At the mouth of the Witchetty River.
The local freshwater fish can only survive in water with a pH between 6.5 and 7.6.
The results are shown in the table below:
