Evening feeding cues of Test brown trout
River Test below Stockbridge: caddis and stonefly pulses
Below Stockbridge on the River Test in July the water runs gin-clear and brown trout move with the light. Caddis and stonefly pulses at dusk force trout out of mid-water lies and into the dusk seam where currents collide and food concentrates.
During the day trout favour quieter holding lies, but as caddis emerge and large stonefly nymphs surge to the surface the fish switch to active hunting. The seam — that ribbon where fast water meets slow — traps emergers and hatches and becomes the prime feeding lane.
How to present the dry-dropper into the seam
Use a 9ft, 4–5 weight fly rod with a 3–4 lb breaking strain and a 12ft, 4–5x leader or a tapered 4lb leader. Tie a dry-dropper rig: a Caddis/Sedge or Rusty Spinner size 14–16 on top as the visual emerger, with a Stonefly Nymph size 8–10 or olive nymph 12–18 inches beneath. Cast across the seam, mend softly, let the dry ride and the dropper swing through the trapped current.
Presentation matters: fish will take the emerger on the surface or the descending nymph. Use subtle strikes and keep light tippet; in gin-clear chalk streams the difference between a hookup and a lost fish is an ounce of drag.
Evening on the Test often ends with a silver flash as a trout slashes the dry in a last frantic pulse of caddis before dusk deepens and the river goes quiet.
