Flav

The river below Ashton Dam is beginning to warm to the point that best fishing is early or late in the day. Big stonefly activity and the same for drake mayflies is about over. Afternoon caddis action remains , and PMD and flav spinner falls at these times of day will bring some top water action. Streamers can also be effective when direct sun light is off the water. Big bows and browns come out to forage at these times because of increased overhead cover.

After the July 10th increase in flow out of Island Park Dam, conditions have stabilized in the river below. Brown drake, flav, little PMD, and afternoon caddis activity still provide top water fishing with AM spinner falls and evening action. Expect recreational floaters to increase during day time hours.
