Your river is the Stour (Worcs) source to conf Smestow Bk, rated poor

The Environment Agency rated the Stour (Worcs) source to conf Smestow 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 fish, insects and other small river life and water plants and algae. 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.
