Evening stealth for River Test trout
Stockbridge beat on the River Test: seams that hold brown trout
Stockbridge and other chalk-stream beats on the Test show fish in inside seams where faster water meets slow and bubbles collect. An angler reads those seams like a map: bubble lines, undercuts and deep glides mark holding lies.
Position downstream or below the fish. Cast upstream so the fly works toward their nose without crossing sight lines. Approach in low light using bank shadows and muted green or brown clothing to avoid a silhouette against the chalk.
Choose a bulky 6–8 inch mouse or foam fly in black or dark brown to give a clear silhouette and vibration. Rig on a short, stout leader: 2ft 20lb butt with 3ft 15lb tippet to keep hook gap clear while moving surface water.
Use roll casts and gentle false casts to keep line off the water. Tread lightly; avoid pressure waves. Wait for genuine rises, then resist the strip-set. Feel the weight first, drop the rod tip and take a couple of steady steps downriver to let the fly dead-drift like stunned prey.
Light and kit discipline
Turn away from the river before lighting any lamp. Use a dim red headlamp only on low; never shine white light at the surface. Change flies at the bank and allow eyes a few minutes to regain night vision before resuming the stalk.
A dark mouse skims a seam, a trout peels a bubble line and the line goes tight against the chalk bank.
