Head to
Wind driftW wind
Western end

A westerly has held for 6 hours, running colder than the water (1°C air against 4°C water). The end it blows into is taking that chilled surface water, so try the sheltered western end instead — off the back of the wind, where the undertow returns food along the bottom. That chill sits in the top of the water, though, and the bed is slower to feel it — on a bottom bait it is the undertow, not the temperature, that puts you at this end. Treat it as a tiebreaker between good swims rather than an override — features and angling pressure usually count for more.

How to fish it · for Trout
When
June–September (best July–August, midnight sun)
Where
Set up a broadside drift and cover the water systematically. Work a bushy searching pattern on the bob and drop a contrasting nymph on the point.
The plan
Plan A

Set up a broadside drift and cover the water systematically. Work a bushy searching pattern on the bob and drop a contrasting 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

Keep an eye on changing conditions — wind shifts and cloud breaks can trigger short feeding spells.

Boat — drift

A gentle ripple is ideal for drifting — broadside drift covering the wind lanes should be productive.

About this water

Landlocked salmon (the Saimaa strain), brown trout, Arctic char, and grayling in cold, dark water. Trolling and fly fishing both work. The light on the water, the maze of islands, and the chance at a Saimaa salmon make this a contemplative venue. Home to the endangered Saimaa ringed seal.
