It is really going strong on the Metolius! Green Drakes are the most exciting news since the last report, mixed with “lesser green drakes” also called Flav’s. The big drakes are averaging size 10, but be prepared with even some 8’s on the water. Flav’s are mostly a size 14 but range up to 12.
Lots of PMD’s #16, BWO #18-20, Mahogany Duns #16, Rusty and Olive Spinners from #10-20.
Caddis have been going nuts, especially small micro caddis (yellow and charcoal #18-20), Tan #14-18, Grey #12-16, Olive #16-18.
Finally Stoneflies are the last big hatch to keep an eye on! Little Olive Stones #16-18 are everywhere, Yellow Sally are tapering down but still important (#16), Golden Stones have improved and are in many areas from the headwaters to below Bridge 99, Willow Flies and Salmon Flies (sparse but could be important on any given day in the next 2 weeks) round out the big bugs.
September is the finest dry fly month of the year on the Metolius so I am not even going to talk Nymphing today.
Oh, but I will talk Bull Trout. There are some big visitors in the river at the moment and the next 2 to 3 months is the best time to try your luck on a beast.
