The Upper Thames is an Operational Catchment divided into 35 waterbodies classified by the Environment Agency. Under the Water Framework Directive (WFD) the water bodies are monitored for a range of ecological and chemical factors, including pollutant content, temperature, invertebrate number and oxygen levels. The water bodies are then ranked overall into the categories Good, Moderate, Poor and Bad.
