We’ve past the peak of the gray drakes on the lower river, but they remain quite numerous. Some green drakes are present, and at nearly dark, brown drakes emerge. PMDs are everywhere, and so are evening caddis. A few golden stones also remain, and flavs are coming on. We cannot be specific about what will work at a given time, so taking life cycle patterns for all these insects (and then others like midges or BWOs) is the best strategy. So the fun of fishing now is finding what they are taking during your visit.
It’s the same deal on the upper river which is finally coming around to great fishing. As with the lower river, approach it with patterns for whatever could be emerging during your visit. Also be prepared for fish to switch interest from one insect to another.
