How to fish it · for Trout
When
The daddy longlegs are on. Buzzers may also come into play as the day warms. Drift conditions look good — cover the wind lanes.
Where
Set up a broadside drift and cover the water systematically. Work Klinkhammer on the bob and Pheasant Tail Nymph on the point.
The plan
Plan A

Set up a broadside drift and cover the water systematically. Work Klinkhammer on the bob and Pheasant Tail 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

Loch Lochy is one of the big Great Glen waters, a deep, acidic Highland loch in Lochaber that runs cold and dark and holds rather more than it lets on. The headline fish, if you can find them, are ferox — the old, cannibal browns that go deep and grow heavy on a diet of char. There's salmon and sea trout running through too, on their way up the system, so you fish a loch like this knowing the water under your boat holds fish you'll likely never see. For the fly angler the realistic quarry is the wild brown of a half-pound to a pound or two, taken loch-style off the shallows and around the burn mouths where the food and the fish concentrate.

Why this score
