Your river is the Smestow Bk - source to conf Wom-Penn Bk, rated moderate
The Environment Agency rated the Smestow Bk - source to conf Wom-Penn Bk as moderate for ecological health in its 2025 assessment, meaning the river is noticeably changed by pollution or engineering. It is held back by phosphate, 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.
