The plan
Plan A

Work Green Peter on the bob and Bibio 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 — at anchor

Windy conditions suit anchoring in productive areas rather than open-water drifting.

The richest island trout lochs. More room for olives, sedges, daddies and surface activity than in peatier systems, while still staying loch-style.

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.
