River Test May Briefing
River Test below Stockbridge — dawn through roughly 08:00
On the River Test below Stockbridge the prime dawn window runs from first light through roughly 08:00 on calm May mornings, when brown trout move into shallower glides, crease lines and carrier seams to pick off small naturals.
Mayfly pulses arrive on warmer days; trout push to the edges of faster water and back-eased seams. Early sedge and caddis emergers will also draw takes; olives and small mayfly nymphs provoke quiet single-rise feeding in slicks and tails of pools. Midges and buzzers produce subtle sipping in shaded runs and slower margins.
Expect risers where flow softens: shallows and deep runs, carrier water margins holding 6-18 inches, tree-shaded sections and water-meadow edges. Fish patrol confluences near Wallop Brook and the Dun, especially around the Timsbury 5 and the 370-yard carrier where current breaks create clear food lanes.
Adopt a light, precise approach: a #14-#18 dry fly or parachute emerger on a 12-15 ft leader with 5X-6X tippet for spooky trout. If no clean rises, switch to a soft-hackle or lightly weighted emerger fished in 18-36 in of water, swung or dead-drifted on the hang. Cast to rising seams, foam lines and the softer side of riffles rather than the main push.
Morning Briefing
Local beats report moderate flow and good wild trout with some stocked fish mixed in. The earliest pale light brings fish onto carrier seams and under overhanging alder; a neat, isolated sip in a shaded meadow margin at first light is the daily promise.
Recommended: soft hackle trout flies
