Your river is the Crouch (Upper) - u/s A129, rated moderate
The Environment Agency rated the Crouch (Upper) - u/s A129 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 and insects and other small river life. 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.
