How to fish it · for atlantic salmon
When
All day — lough fishing is best in a good wave. Early morning and evening can produce in calm conditions.
Where
Work the drift lanes from the upwind shore across the productive zones. Cover bay edges, underwater reefs, and any areas where the bottom shoals.
Method
Fish a sensible line-and-fly combination for the height and pace of water.
Kit
10 ft #7/8 single-hander, floating line, 10–12 lb fluoro leader. Boat seat and waterproofs for the drift.
Why this works
Poor conditions. Clarity is favourable (95), Feeding time is weakest (10).

About this water

Loch Morsgail lies in the wild interior of western Lewis, held in a basin of peat and rock under the Uig hills, and is one of a small number of Hebridean lochs where salmon and sea trout run in genuine numbers. Salmon enter the system from late June after a good spate; sea trout follow through July and August and hold in the shallower margins on the evening rise. The brown trout fishing is a bonus — dark, hard-fighting peat-loch fish that take a wet fly with conviction through the main season. Boat fishing is the standard approach: drift the traditional lines with a team of three wet flies on a floating line, concentrate on the leeward shores when the wind holds, and keep moving. The loch is managed as a let fishery with boat access through the Morsgail estate, and access to the glen is on foot or by Argocat. When Morsgail fires — which takes the right combination of water and wind and a dropping barometer — it produces the kind of day that has you booked back for the same week next year.

Sea trout: Variable seasonal (2026) — Lewis loch system — sea lice impact common to all Outer Hebrides sea trout fisheries. Stocks diminished from historical levels. Sea trout remain present but the fishery must be presented cautiously.
