Your river is the Severn conf M Wenlock-Farley Bk to conf R Worfe, rated moderate

The Environment Agency rated the Severn conf M Wenlock-Farley Bk to conf R Worfe as moderate for ecological health in its 2025 assessment, meaning the river is noticeably changed by pollution or engineering. It is held back by water plants and algae, phosphate and temperature. 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.
