Your dataset indicates that this waterbody has a poor ecological status.
High turbidity and green water colour indicate the presence of large quantities of phytoplankton (algae), typical of an algal bloom.
Algal blooms can be caused by high nutrient loads delivered from the catchment or the release of stored nutrients in the sediment.
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.
