Water Quality Monitoring

Council regularly monitors the health of five (5) main creek systems within our catchment area. These five sites include:

• Terrys Creek
• Shrimptons Creek
• Porters Creek
• Buffalo Creek
• Archers Creek

Monitoring water quality 

Water quality is monitored by testing for both biological factors and chemical elements in the water.

Biological factors or biological sampling indicate the number and diversity of aquatic macroinvertebrates (water bugs)  present in our creeks. Samples that include aquatic macroinvertebrates sensitive to pollution suggests a healthier creek system.

Chemical monitoring involves measuring characteristics of the water in a creek using a probe (for example, the level of dissolved oxygen and turbidity), and taking water samples back to the laboratory to measure characteristics such as amounts of nitrogen and faecal coliforms in the creek.
