Your dataset indicates that this waterbody has a poor ecological status.
These nutrient concentrations also favour the formation of algal mats which may influence aquatic biodiversity.
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.

Total number of participants :

Notes: 
Warm, dry sunny weather for over 10 days. Flow from upstream to bridge was very slow, sides of water had brown algae/sludge floating on surface. Large tree trunk and wooden pallet, (with large nest possibly swan) were straddled across just in front of bridge, not sure if deliberately placed or accidental. That seemed to slow the flow. Downstream beyond the bridge the water was flowing faster, but at my sampling point slow enough for tadpoles to be seen swimming around, and what may have been a cased caddis crawling along some submerged wood.
