Your river is the Saredon Brook from Source to River Penk, rated moderate
The Environment Agency rated the Saredon Brook from Source to River Penk as moderate for ecological health in its 2025 assessment, meaning the river is noticeably changed by pollution or engineering. It is held back by fish, insects and other small river life and ammonia. 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.
