Your river is the Hay Dulas Bk - source to conf R Wye, rated moderate

The Environment Agency rated the Hay Dulas Bk - source to conf R Wye 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. 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 dropped since the previous assessment.
