Dawn Windows on the River Test
Leckford beat: the first bright hour after sunrise

Low June flows on the River Test around Stockbridge and Leckford open a very specific dawn window: the first bright hour after sunrise. Brown trout hug soft seams, inside bends and the tail of gravel runs where current feeds insects into concentrated lies.
Shallow margins of 1–3 ft hold most fish at first light. The crease between pacey water and slack water, bubble lines along weed and caddis seams beneath undercut banks are prime locations. Grayling show in similar water but often require a slightly slower retrieve.
Fly choices & presentation
Small caddis and emergers in sizes 14–18 are the default search patterns; if trout rise, switch to a size 14–16 dry. Leaders run fine: 4X–6X tippet in clear, bright conditions. Presentation is simple — a dead-drift across the seam with a short upstream reach cast to remove drag. Precision wins on a chalkstream where fish see every move.
Leckford also runs separate stillwaters with rainbows and browns, but in the river itself the Test is classic brown trout and grayling water. Expect short pulses of surface activity around caddis hatches at dawn rather than all-day feeding, and watch the tail of gravel runs for that telling flash: a neat brown trout slurp at the head of a seam.
Recommended: fine fluorocarbon tippet
