- Ecology: Moderate
- Chemical: Failing to achieve good
What this classification means
Classification for the fished main stem — EA waterbody 'Tyne from Watersmeet to Tidal Limit' (GB103023075801), Cycle 3 / 2022: Moderate ecological status (invertebrates dropped from High in 2019 to Moderate in 2022). The 'Failing to achieve good' chemical status reflects the England-wide ubiquitous-substance failure (mercury, PFOS, PBDE in biota), not a Tyne-specific pollution event. The reach is designated heavily modified and is a Drinking Water Protected Area. Note: the prior entry pointed at GB103023075650 (March Burn, a minor tributary), not the salmon water — corrected 2026-06-09.
