Three dusk beats on the River Test
Three dusk beats on the River Test under Stockbridge

Stockbridge's inside bend below the town is a signature chalkstream seam where brown trout and grayling sit tight as caddis adults hatch. The most productive water isn't the headline glide but the tail of the glide, shallow bank shelves and crease lines beside weedbeds.
Evenings demand long, quiet presentations. A double-dry rig with the trailing fly 15 to 18 in behind the point covers adult and emerging caddis at once. Soft-hackle patterns and compact caddis dries mimic the skittering adults; match the size and tone to what drifts past the shelf.
Reading the rise
Nose breaks and splashes mean adults. Dimples and faint rings point to emergers or pupae taken just under the surface. Fish will slide out of the main flow into softer water to intercept drifting insects; target the soft water below riffles and the narrow margins beside weedbeds where current eases.
Stealth is compulsory. Move low and downstream, cast slightly off-line and avoid crossing the trout's lane. Chalkstream trout in shelves less than about 1 m depth spook at silhouettes; short steps and shadow-free casts win more takes.
At dusk a trout will roll on a caddis, four rings fan, and the light on the Test goes thin and green.
