Established on 1st September 1989, the NRA is an independent public body charged with safeguarding and improving the natural water environment. It is responsible for flood defence, regulating the quality of rivers and groundwaters, balancing the needs of various water users, protecting and improving fish stocks and promoting water-based recreation of all kinds. The NRA is committed to improving wildlife habitats and conserving the natural environment in all it undertakes. The River Cherwell and its tributaries are regularly sampled by NRA biologists for aquatic invertebrates. These animals indicate the ecological quality of the watercourses studied. The main rivers within the catchment are generally of gocxd quality with a wide range of invertebrates, including pollution sensitive mayflies, stoneflies, dragonflies and caddis-flies. Rivers and streams in and around the urban areas of Banbury, Bicester and Oxford are of a lower ecological quality and have fewer animals, including pollution-tolerant midges, leeches and worms. Poor ecological quality can be detected in some small tributaries which suffer from pollution incidents.
