Your river is the Wesley Bk - source to conf R Worfe, rated poor
The Environment Agency rated the Wesley Bk - source to conf R Worfe 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, 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.
