Your dataset indicates that this waterbody has a poor ecological status.
Elevated nitrate and phosphate concentrations indicate high nutrient loading from the surrounding catchment, creating conditions of eutrophication.
Turbidity values are also high and may lead to additional negative effects such as reduced light availability for aquatic biota and favours eutrophication.
Potential sources of nitrate pollution include fertiliser runoff, sewage discharge and livestock activities.
Have you observed any pollution source near the waterbody? It would be helpful if you could add this information by editing your data record to include these observations.
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.
