The Environment Agency measures water quality of the river systems in England. Each is given an overall ecological status, which may be one of five levels: high, good, moderate, poor and bad. There are several components that are used to determine this, including biological status, which looks at the quantity and varieties of

This River Blackwater should not be confused with the River Blackwater in north-east Hampshire, which is a tributary of the River Loddon and (indirectly) of the River Thames.
Another similarly named waterway in Hampshire is Black Water, a small stream which flows eastwards across the New Forest, passing under Rhinefield Ornamental Drive, before joining Ober Water and Highland Water just north of Brockenhurst to form the Lymington River.
