How to fish it · for atlantic salmon
When
Fish early morning (first light to 9am) and late evening (7pm to dark) only. Midday heat stresses fish — stop fishing and rest pools when the sun is high. This is welfare-critical above 20°C.
Where
Focus on the slower water at pool edges, inside bends, and behind large boulders. Fish won't hold in the main current at this height. Streamy water that's normally too shallow can hold fish in high water.
Method
Lively swing near the surface. Floating line, the fly fishing in the top 12 inches. The fly should look alive — a small mend to accelerate at the right moment can trigger a snapping take.. Floating line. size single or double sizes 4 10 Black Bear series
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 reasonable, though not ideal. 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.

About this water

The Little Southwest Miramichi feeds the main Southwest above Doaktown — smaller, clearer water than the main stem, running through mature spruce forest in the New Brunswick interior. In low-water summer conditions, when the main river becomes difficult, the Little Southwest continues to fish because its narrower channel concentrates fish into definable lies. Mid-summer grilse are the primary quarry, with fresh fish throughout July and August. The upper reaches are remote and see relatively few rods, which is the most important thing about them.
