Your river is the Beanhill Brook source to shawbirch B4394, rated poor
The Environment Agency rated the Beanhill Brook source to shawbirch B4394 as poor for ecological health in its 2025 assessment, meaning the river is badly affected, with much of the expected wildlife missing. It is held back by insects and other small river life and phosphate. It fails the chemical test, as every river, estuary and stretch of coast in England does, because of long-lasting pollutants such as mercury, PFOS (a forever chemical) and old flame retardants.
