July offers a smorgasbord of tasty terrestrial and aquatic insects to the numerous trout which inhabit the Green River. July is the driest month of the year in eastern Utah. This dry weather allows the entire 30 miles below Flaming Gorge Dam to be crystal clear. This helps spread anglers and rafters out and the lower sections of the river fish very well.
In early July anglers may encounter the tail end of the cicada hatch, as well as prime time yellow sallies and pmd mayflies.
