Chalkstream Dawn: Test Trout
River Test below Stockbridge: June dawns favour pre-hatch blue‑winged olive activity
On early June mornings the first light on the Test below Stockbridge often provokes pre-hatch feeding. Trout show in tight seams and tailouts before a full hatch builds, with Blue‑winged Olive or “summer olive” activity, caddis and occasional Pale Morning Dun-like mayflies arriving as the month warms.
Best lanes are obvious: heads of runs, tailouts and the gentle seams beside weedbeds where faster water meets a slow strip. Trout lie where interception is easiest and bugs drift first.
Short-line dawn tactics
The go-to dawn rig is a short-line leader of 8–12 ft and a 2‑fly nymph/dropper. Run a Pheasant Tail Nymph in 14–16 as the point and a smaller 16–18 trailer or emerger. Keep the first drift tight to the bank or soft seam and fish the first 30–60 minutes hard if only occasional rings appear.
Have simple dries ready for surface windows: parachute Adams, elk hair caddis and a small CDC emerger or sparkle‑dun. If regular sipping starts, switch instantly to a fine dry or emerger—June Test trout will lock onto one food item and ignore the rest.
Typical June flows are low and clear on the chalkstream; any overnight rain will colour seams and shift lies. A single pale mayfly pinned to the film at first light can produce the month’s loudest run.
