Your river is the Ford Brook from Source to River Tame, rated moderate

The Environment Agency rated the Ford Brook from Source to River Tame 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, ammonia 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.
