Yesterday we fished the Blackfoot River at several locations below the dam. The flow out of the dam has been reduced to an amount that concentrates fish in the deeper runs, pockets, and holes. That means anywhere you can approach the river, look for the deepest parts and you will have your chances. Small streamers, no pattern in particular, seemed to work best for us, until a relatively sparse BWO emergence brought fish up in the water column water away from the deepest parts when mid afternoon water temperatures climbed to 45 deg. F. Then emerger and dun patterns, about #18, were a sure bet to attract trout. The experience I describe for yesterday is one that repeats itself in many streams this time of year. That is streamer and BWO life cycle patterns being effective. Try it anywhere on your favorite waters large or small.
