Your river is the Tame (W/ton Arm) source to conf Oldbury, rated moderate

The Environment Agency rated the Tame (W/ton Arm) source to conf Oldbury as moderate for ecological health in its 2025 assessment, meaning the river is noticeably changed by pollution or engineering. It is held back by insects and other small river life, organic pollution (bod) 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.

It is held back by insects and other small river life, organic pollution (bod) 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.
