Getting ready for fall Baetis hatches? Blue Winged Olive hatches are one of our major hatches in the fall, and the fish really take notices of all the little olive bugs on the water. Rapid, Castle, Spearfish, Crow, and Sand Creeks all see significant hatches of BWO’s from mid September through October typically, especially on cool and overcast days. The main portion of the hatch can last anywhere from 2-5 hours, and the trout are actively feeding on the adults during the entire hatch. While the fish aren’t typically super selective, it’s good to have a few different patterns in different sizes to match the insects closely
