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

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

High phosphate concentrations may also indicate a local pollution source (e.g. wastewater outlet, industrial emission or an agricultural runoff).
Have you identified any such activities?  It would be very helpful if you could add this information by editing your data record to include this observation.
