About this water

Britain's longest river — fly fishing focus is upper and middle reaches from Welsh border (Shrewsbury) to Bridgnorth. A big, powerful spate river; grayling are the primary target (some of the Midlands' best), supplemented by brown trout in upper reaches and recovering salmon runs. The long, even-paced glides are ideal grayling water. Euro/Czech nymphing is most consistent; dry fly works in upper reaches and on calm days. The tributaries (Teme, Onny, Tern, Perry) often offer better trout prospects than the main river. Club and association water with day ticket access. Atlantic salmon are assessed by the Environment Agency against each river's Conservation Limit — many principal rivers are classed 'at risk' with mandatory catch-and-release byelaws; check current rules before fishing.

What this classification means

EA waterbody 'Severn - conf Bele Bk to conf Sundorne Bk' (GB109054049142) — the Shrewsbury reach of the upper-middle Severn, representative of the venue's fished water from the Welsh border down towards Bridgnorth (classifying sites at Montford Bridge, Isle of Bicton and Shelton). Latest EA data (Cycle 3, 2022): Moderate ecological status (sewage and rural-runoff phosphate/macrophyte pressures). Chemical 'Fail' reflects the England-wide ubiquitous-substance failure (mercury, PBDE and PFOS in biota); the 2022 cycle itself records chemical as 'does not require assessment'. Corrected 2026-06-18 from GB109054049260, which is Cound Brook (a Severn tributary), not the main stem. NB: the venue's stored coordinates are in Worcestershire and should be moved up to the Shrewsbury–Bridgnorth reach.
