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.

Notes: 
Woodland Brook, surrounded by broadleaved woodland. This location is predominantly within woodland though upstream lakes feed into it. These private lakes were stocked with trout prior to a poisoning event some years ago. Upstream is a Thames Water treatment site which discharges into the brook. I would like to test upstream of this in the future. Especially due to the woeful results downstream I feel it likely discharge effluent is the culprit here.
