Chalk‑stream morning briefing: River Test update
River Test below Stockbridge: low flows, big caddis pulse

River Test below Stockbridge is running low and clear this morning. Gravel glints through a shallower seam; tailouts have tightened. The strongest caddis pulse in recent weeks is on the upper reaches, and wild brown trout are keyed to surface and near‑surface food.
Where it's working
Mid‑channel runs below the old bridge and the sheepwash hold fish that are willing to take dries during short glassy windows. The riffle tails near Sutton Scotney are holding fish on the drop where nymphs thread the seam.
Tactics and tackle
Short, direct presentations win: polished leaders, a short leader length and fine tippet. Short‑line nymph rigs fished tight to gravel are producing immediate takes; during caddis rises, small elk hair patterns and dark CDC comparatives are doing the damage.
Anglers report cautious feeding between 08:00 and 10:30, then a quieter midday; late afternoon saw a second pulse. Wading is light but cautious—wading boots that keep a low profile work best on the cleaner gravel. Expect pockety dry‑fly windows and hard strikes from compact, wild trout under bank shade as the hatch peaks.
