Phosphate levels are high in this water body resulting in a classification of bad for phosphate. There are many causes but the impact from agricultural runoff in the upper reaches is one of the causes for the high levels.

Dissolved oxygen levels fluctuate and although there is no WFD failure for this, levels do drop in late summer and early autumn. One of the reasons for this is most likely the increased plant growth, which is exasperated by the increased nutrient levels in the water from phosphate.
