Loch Tay

Winter sunrise over Loch Tay with Ben Vorlich and the Ben Lawers massif silhouetted behind the loch in dawn light.

Loch Tay sits at the head of the Tay system in Perthshire — fifteen miles long, deep in its central basin (over 500 feet, more than most people realise), and holding the strange Highland combination of spring salmon, wild brown trout, Arctic charr, and ferox.

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
Fair — water clarity is working for you, but time of day is the limiting factor today.

About this water

Loch Tay sits at the head of the Tay system in Perthshire — fifteen miles long, deep in its central basin (over 500 feet, more than most people realise), and holding the strange Highland combination of spring salmon, wild brown trout, Arctic charr, and ferox. Mandatory catch-and-release applies. Declining Atlantic salmon populations are Category 3 under Scottish Government classification; every fish returned matters. The salmon come up from the river below and hold in the shallower bays at the east end for much of the spring — trolling is the traditional method and still the most productive, though fly fishing from anchored boats on the morning calm can produce when conditions are right. Brown trout fishing in the eastern and western basins is classic Highland loch-style work, with a team of three wet flies drifted on a moderate ripple from April through June. Arctic charr live in the deep central basin and surface rarely; catching one is a specialist pursuit involving down-rigged deep presentation and long patient days. The loch opens on 15 January for salmon, matching the river — one of the earliest openings in Scotland. Boats and permits through the Kenmore and Killin hotels and the Loch Tay Fisheries.

    Loch Tay trout and char permits cover arctic charr from 15 March to 6 October. Arctic charr in Scotland are usually by-catch of trout fishing rather than a mainstream target. Return requirements may apply — check current permit conditions. Arctic charr are conservation-sensitive in Scottish lochs.
