Damselflies will be migrating to adulthood in July, so there are opportunities to cast damselfly nymph imitations and, later in the month, adult patterns. Mitten, Kipp, Ghost, Little Goose, and Mission lakes are all good early July choices. Some of these lakes are pretty big, so a float tube or pontoon boat will help you reach a lot more trout. Expect windy conditions.
You can also find hatches of Callibaetis this month, and scud and leech patterns are always good choices. On windy days, terrestrial insects such as ants, beetles, and hoppers may be blown on to the water, but they are more important in August than they are in July.
Be prepared for evening hatches of traveling sedges. A size 8-10 Goddard Caddis is effective when skated across the surface.
As the weather warms up, the trout will be in the deeper sections and fishing will slow down.
