Your dataset indicates that this waterbody has a moderate ecological status.
Elevated nitrate and phosphate concentrations indicate high nutrient loading from the surrounding catchment, creating conditions of eutrophication.
Potential sources of nitrate pollution include fertiliser runoff, sewage discharge and livestock activities.
These values are expected to vary throughout the year as a result of weather patterns and changes in land use. Please help us to better understand this ecosystem by continuing to make measurements.
