Your river is the Alne - source to conf Preston Bagot Bk, rated poor

The Environment Agency rated the Alne - source to conf Preston Bagot Bk 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 water plants and algae 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.
