River Test July Dawn Briefing
Leckford Estate reach, north of Stockbridge: dawn caddis pulse
At first light to the first three hours in July the River Test below Stockbridge turns over with rising brown trout, often keyed to caddis and small surface insects. Fish show on glide tails and the edges of gravel runs rather than flash on shallow riffles when the water runs low and clear.
Focus on the Leckford Estate and Broadlands stretches downriver—classic Test fly-water where cool groundwater keeps trout in oxygenated riffles and deeper tails. When the river clears, expect the fish tight to seams and deeper gravel lanes instead of mid-channel tailouts.
What’s biting and what to watch
Early dry-fly windows favour caddis and general mayfly activity; as the sun climbs trout go selective and move to the coolest pockets. Practical temperature rule: sample the water before starting and again after sunrise and shift to the coolest glide or riffle tail available.
Rig light: long leaders, delicate presentation and 5X–6X tippet. Tie three reliable patterns: Elk Hair Caddis (14–16), Parachute Adams (16–18) and Klinkhåmer Special (14–18) for emergers. A cautious cast to the ripple tail of a glide at dawn often produces the first convincing rise.
Start upstream, work short downstream drifts through riffle tails and gravel runs, watch for subtle sipping rises—brown trout breaking a perfect film under a pale Hampshire sky makes the whole morning worth it.
