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

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

Turbidity values are also high and may lead to additional negative effects such as reduced light availability for aquatic biota and favours eutrophication.
High phosphate concentrations may also indicate a local pollution source (e.g. wastewater outlet, industrial emission or an agricultural runoff).
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.
