We’ve had decent weather this week with temps in the 50s and warming into the 60s. Water temperatures have been reaching the upper 40s on the Lower Snake River below Moose Bridge. We are also starting to see the first skwalas of the season, which makes it possible to fish with large attractors along banks, seams, inside turns of riffles, and the current margin of riffle pools. BWO imitations are also doing well most days in riffles and riffle pools along seams. The afternoon is the best time for these flies.
As far as nymphing goes, use either a double nymph rig or a dry/dropper rig. Large stonefly imitations and small mayfly and caddis imitations are working well. Aim for riffles, banks, bankside troughs, seams and confluence lines.
On good days, streamers are really effective, but overall the consistency is low. We’ve been finding success with intermediate sinking tips, 3ips and 6ips tips, and 5 to 7 feet of T-11. The best places for streamer action have been banks and structure, riffle and riffle pools, and seams. Moderate sized baitfish imitations and bigger, articulated streamers are effective.
