Your river is the Middle Gill Beck from Source to Kilton Beck, rated bad

The Environment Agency rated the Middle Gill Beck from Source to Kilton Beck as bad for ecological health in its 2025 assessment, meaning the river is severely damaged, with most of the expected wildlife missing. It is held back by fish. 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.
