Your river is the Skerne from Source to Carrs, rated poor

The Environment Agency rated the Skerne from Source to Carrs as poor for ecological health in its 2025 assessment, meaning the river is badly affected, with much of the expected wildlife missing. It is held back by insects and other small river life, water plants and algae and dissolved oxygen. 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.
