How to fish it · for Atlantic Salmon
When
All day is fishable. Peaks around mid-morning (10-12) and late afternoon (4-6pm). A change in light — cloud passing over the sun, or the first shadow reaching the water — can trigger a take.
Where
Prime time. Fish the classic taking lies hard — heads and tails of pools, current seams beside faster water. Fresh-run fish will be settling into lies as the river drops into shape. This is the golden window.
Method
Medium-paced swing, fly fishing just below the surface. Fish are willing to move — a steady broadside presentation across the current is ideal. Vary speed through the swing.. Floating line, possibly slow intermediate in deeper pools. Small-medium: size 8-12 doubles, small tubes. Fish are willing to move — let them come to the fly.
Kit
13 ft #8/9 double-hander in spate, 10 ft #8 single in low water. Floating line plus a fast-sink tip. 12–15 lb fluoro tippet.
Why this works
The river is in textbook shape. River dropping nicely into shape after a lift — textbook conditions. Clearing nicely — classic taking conditions. 13.8°C — in the ideal taking range for autumn salmon. This is the window experienced salmon anglers wait for — if you can get to the river, go now.
