Your dataset indicates that this waterbody has a poor ecological status.

Significantly elevated phosphate concentrations indicate eutrophic conditions which typically result in algal blooms.

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.
High phosphate concentrations may also indicate a local pollution source (e.g. wastewater outlet, industrial emission or an agricultural runoff).
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.
