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.
A patient day, if you fancy it
Good wave on — drift country. Take your time — read the water before you cast.
Conditions on the water
Some readings unavailable — check directly before fishing.
The brief
The plan
Set up a broadside drift and cover the water systematically. Work Invicta on the bob and Greenwell's Glory on the point.
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.
Keep an eye on changing conditions — wind shifts and cloud breaks can trigger short feeding spells.
A gentle ripple is ideal for drifting — broadside drift covering the wind lanes should be productive.

How to get to the water
Where the rules change
- Salmon11 February → 31 October
- Trout15 March → 6 October
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.
