Your dataset indicates that this waterbody has a poor ecological status.
There is strong evidence that algal blooms have occurred, but turbidity values are lower than expected. Are you sure your observations are correct? Please double check your results.
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.
