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.
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.
