Your river is the Ure from Mill Beck to Thornton Steward Beck, rated moderate

The Environment Agency rated the Ure from Mill Beck to Thornton Steward Beck as moderate for ecological health in its 2025 assessment, meaning the river is noticeably changed by pollution or engineering. It is held back by water plants and algae. 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. Its ecological rating has improved since the previous assessment.
