How to fish it · for Atlantic Salmon
When
Early morning and late evening are best by far. Low, clear water makes fish spooky in daylight. The first and last hour of light are worth more than the entire middle of the day.
Where
Fish are concentrated in the deeper pools and under any available cover. Focus on the deepest lies — pool hearts and tail croys. Approach very carefully, avoid silhouetting yourself against the sky. Dawn and dusk are your windows.
Method
Surface or just sub-surface. Consider a riffling hitch or Portland hitch to skate the fly across the surface — devastating in warm, low water. Alternatively, dead-drift a small fly upstream like a nymph.. Floating line. Tiny: size 12-16 singles or doubles, hitch tubes. Ultra-discreet presentation for spooky fish in warm, clear water.
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
Conditions are favourable — this is a day to be on the water. Peak summer — grilse and summer salmon are active and willing. Small flies, lightly dressed, fished with purpose. No historical catch data available for this river — prediction based on current conditions only.
