Blackfoot River Fishing Report 4/20
Dry fly action has been fairly limited, especially with current river Temperatrues. However, flows have consistantly been dropping and the water clarity getting better by the day. On warmer afternoons you can still occasionally find pods of trout keying in on adult brown mayflies and even the ocassioal skwala. BWO's and Callibaetis have been spotted to hatch sporadically during the late afternoons. The Blackfoot ususally remains the coldest running river for the longest time, so the surface game may remain difficult until early summer months
Nymphing has remained the most consistent and productive approach, very similar to what we’re seeing on the Clark Fork. Heavier rigs are key right now to get down in the faster, dirtier water. Both indicator and tightline setups are working well as long as flies are in the zone. Stonefly nymphs paired with worms or small dark nymphs—like Pheasant Tails and perdigons—are all solid producers. Focus efforts on softer water: deeper runs, tailouts, and protected seams where fish are holding out of the main current. With whitefish spawning both in the tributaries and the main river, anything bright pink or red that resembles the color of an egg will produce.
Streamer fishing has also stayed consistent. The dirty water actually plays in your favor here, giving you a good chance to move fish with larger, high-contrast patterns. A slow, deep presentation is still critical—target structure, banks, and slower buckets with methodical casts. Sculpin patterns, Woolly Buggers, and other medium to large streamers in darker colors have been effective, especially under overcast skies. As clarity continus to get better and the skies become brighter, golden and white streamers start to become more effective.
One key note: the upper sections of the Blackfoot are currently fishing better than the lower river. As always, conditions can change quickly this time of year, so keep an eye on flows and clarity and adjust accordingly
