Stockbridge caddis morning window
Stockbridge Side 0.47m — classic chalk‑stream morning window

Stockbridge Main and Side are running low and clear, fish tight to cover and hyper‑selective as August warms the Test. Brown trout dominate the action, with the odd grayling showing in softer seams. A short caddis pulse at first light puts rise rings in the slow glides.
Best rigs are dry‑fly + dropper combos: a size 14–16 tan caddis or sparse X‑Caddis on the surface with an 18–22 black midge emerger 15–30cm below; or a small olive emerger/CDC shuttlecock over a size 18 pheasant‑tail nymph 20–40cm down. Terrestrials work when bankside ants fall; pair a tiny ant with a tiny caddis larva dropper.
Use a 12–15ft tapered leader with a 4X–5X top tippet and 5X–6X on the dropper. Keep the dropper shallow — 10–40cm — and fish upstream with reach casts to eliminate drag. Presentation beats weight; dead drift and gentle twitches on emergence imitate natural behaviour in clear chalk water.
Where to fish and how the river reads
Target soft seams, weed edges and broken surface lanes below Stockbridge bridges. Low gauges demand stealth: long casts, light gear and a careful approach along the bank. Expect the best takes in the first hour of light, when a wary brown will quarter up into a sunlit seam and sip a tan caddis without warning.
A brown slipped from a patch of filamentous weed, nailed a sparse tan caddis in the first grey of morning — the classic Test take, delicate and immediate.
Recommended: CDC dry fly
