Your river is the Derwent - conf Cocker to tidal, rated good
The Environment Agency rated the Derwent - conf Cocker to tidal as good for ecological health in its 2025 assessment, meaning the river is only slightly changed from its natural state. 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.
