Hatch Status

Hecubas (Red Quills) have been seen up and down the river and trout are keying on them

Conditions

Hecubas (Red Quills) should be active up and down the river through late September, with afternoon Baetis hatches and small cream crane flies rounding out the day. Flows at the Magic Dam gauge are running stable, and overcast skies with temperatures climbing into the low 70s will help bring insects to the water. Consider Red Quills, Chubby Chernobyl, and Rubber Legged Stones as the day warms, and stay alert for Tricos and small streamers if the hatch patterns intensify.
