How to fish it · for brown trout
When
Nymphing can work through most of the day.
Where
Cover mixed depths.
Method
Start with tight-line nymphs and adjust if fish rise or drift higher.
Kit
9 ft #4 rod, floating line, 12 ft tapered leader to 4–5 lb fluoro tippet.
Why this works
⚠️ Water at 20.9°C — above the brown trout caution line (18°C). Fish dawn or dusk only. Land it fast, wet hands, no air shots. Otherwise poor — water clarity is in the right range.

About this water

Small intimate river near Masham with the private, wild feel that makes Yorkshire fishing special. Runs, holes, and pools with overhanging cover where stealth is paramount. Dry fly and spiders are equally at home; the Burn's scale suits both. The Hare's Lug (hare's ear soft hackle) tradition is strong here — a distinctively Yorkshire pattern that blurs spider and nymph. The Burn joins the Ure just south of Masham, so this entry should pin the Masham / lower Burn area rather than the North York Moors. Overhanging trees demand accurate short casts and roll-casting. Syndicate and estate-managed access (Fly Fishing Yorkshire syndicate, Swinton Estate). A river for anglers who value intimacy over size.

What this classification means

Classification for the fished main stem of the River Burn at Masham / Swinton — EA waterbody 'Burn from Leighton Beck to River Ure' (GB104027069310), Ure Middle and Lower operational catchment, Swale Ure Nidd and Ouse Upper management catchment, Humber river basin district. Latest EA data (updated 17 March 2025), Cycle 3 2022: Moderate ecological status, held at Moderate since 2019. Heavily modified water body sitting within the North Pennine Moors SAC/SPA. The step down from earlier Good classifications is driven by the fish element (RNAG: surface-water abstraction affecting flow) plus a phosphate 'suspect data' reason-for-deterioration; invertebrates, macrophytes and the other physico-chemical elements are High/Good. Chemical 'Fail' reflects the England-wide ubiquitous-substance failure (mercury and PBDE in biota — measures delivered, awaiting recovery), not a Burn-specific pollution event; the 2022 cycle itself records chemical as 'does not require assessment'. Classifying monitoring sites include Burn at Masham (Badger Lane Bridge) and Burn at Swinton Saw Mill Race. Note: the prior entry pointed at GB104027068800 (Ings Goit from Source to Burneston Beck), a separate small waterbody in the Swale catchment, not the Burn — corrected 2026-06-18.

What would change the calculation
Cooler water — back toward the 10–16 °C ideal band — would lift the score and ease welfare.
The dawn and dusk windows score higher than the midday lull.
