Test Evening Rises
Stockbridge on the River Test lights up at 6–9 PM
Brown trout — local brownies of 2–5lb and occasional bruisers — climb from 3–6ft glides to sip Ephemera danica duns in pulsing waves. Size 10–12 mayflies erupt in 20–40 minute surges; tails break in precise 5–10 second beats as fish take emergers in the surface film.
After that, sedges take over. Caddis adults, mottled 14–18mm sedges, skitter and egg‑lay near alders after 8 PM; trout switch from head‑and‑tail sipping to violent slashing. On Houghton Club beats and the Cricket Corner at Bossington, porpoising boils can span 18 inches across a pool.
How to read the windows
Scout from the bank at 7 PM: spinners drift at a steady pace, low pressure and cloud thickening sharpens pulses. Five or more rises in ten minutes means prime time. Fish move to shallow seams when sedges mass along margins.
Rig with long tapering 8–12ft leaders and fine 4-6X leaders for delicate presentation. Tie on #12–16 dries: a Hatch Matcher or French Partridge Spider for the mayfly, and a deer‑hair Goddard Sedge for the frantic sedge runs. Cast upstream, let the fly swing at a 45° angle, twitch the sedge and expect takes in 2–3ft shallows.
Dusk is the ticket — the sweet spot is late evening when light fades and insects pour off the chalkstream. On the Test a single pulse can fill a beat with visible fish; a final sedge burst often sends a dozen porpoising rises across the pool as fields go dark.
