How to fish it · for trout
When
May-September; peak June-August
Where
Set up a broadside drift and cover the water systematically. Work a bushy searching pattern on the bob and drop a contrasting nymph on the point.
The plan
Plan A

Set up a broadside drift and cover the water systematically. Work a bushy searching pattern on the bob and drop a contrasting nymph on the point.

Plan B

If the main plan is not working, switch to a smaller, more imitative pattern fished slower and deeper. A change of drift angle can also make a difference.

Watch for

Evening tends to be the best period in summer — stay late if you can for a sedge or spinner fall.

Boat — drift

A gentle ripple is ideal for drifting — broadside drift covering the wind lanes should be productive.

About this water

A chain of shallow, crystal-clear limestone lochs along South Uist's Atlantic coast — one of the most distinctive trout fisheries in Europe. The machair is a unique Hebridean landscape of shell-sand grassland, and the lochs that sit within it have alkaline water over white sand, supporting exceptional invertebrate life and wild brown trout that rise readily to the dry fly. The trout are typically three-quarters of a pound to a pound and a half, beautifully marked and immensely hard-fighting for their size. Some lochs hold sea trout. The clarity of the water means fish can be spotted and stalked — a form of fishing more reminiscent of New Zealand spring creeks than Scottish lochs. Published season: brown trout 15 March to 30 September; salmon/sea trout 1 February to 31 October. The solitude and otherworldliness of the machair in summer evening light make this as much a pilgrimage as a fishing trip.

Sea trout: Variable seasonal (2026) — Machair loch systems of South Uist once famous for sea trout; stocks have declined sharply in line with the wider Hebridean pattern (sea-lice pressure, reduced marine survival). Still fishable in the right conditions but cannot be promoted as reliable. Local knowledge and timing essential.
