Your dataset indicates that this waterbody has a poor ecological status.
Potential sources of nitrate pollution include fertiliser runoff, sewage discharge and livestock activities.
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.

Notes: 
Keith Stevens and Clare Higson, this is half a mile below a sewage outfall, it is also below a Golf course which has carried out major works on the river upstream inputting large quantities of silt. Upstream is agricultural land, immediately upstream is an outfall from a fishing lake. Adjacent are horse paddocks. A small quantity of foam was visible 100yards upstream at the Lock, some algae is adhering to stones and gravels but not in large quantity, there has been no significant rain for some while now and the river is low for this time of year.
