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.
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.
