Yesterday in the shop I heard 2 customers and an employee talk about fishing green drakes on the Metolius River in the last day or 2. It is now getting late for the hatch to still be present, so this will not last too many more days I am sure, but if you are headed to the river today and over the holiday weekend make sure the drakes are part of your kit. 
The main hatches now include PMD’s #16 on all sections of the river, Yellow Sally’s #16 (although you could seen them as big as a #12 occasionally), Little Olive Stones #16-18, Blue Wing Olives #20 mostly on the middle river, Golden Stones #8-10 mostly on the upper river from Allingham up to the Headwaters, and a lot of Caddis including #16 Tan, #16-18 Olive and #14 Grey. 
All areas of the river from the headwaters section down to below Bridge 99 to the Candle Creek area are good now. 
Dry fly times are usually noon to 4’ish, and 8 to dark, but keeping your eyes open for the little hatches that could create a rising trout opportunity (an RTO) (HAHAHA) anytime of the day is a smart thing to do as an angler. 
Here is where I’ll impart the better casting capabilities to the report. Not too many years ago when I actually had time to teach casting lessons I offered a class to clubs and to individuals called the skills class. It was designed for an intermediate and above caster and it focused on Reach Mending, Parachute Casts, Wiggle Casts and Off Shoulder Casts. It had nothing to do with distance and everything to do about achieving a longer drag free drift. Notice the difference here to what I will talk about later in the lakes section. Often, spring creek fishing, and most river fishing is not about distance, it is about control. Controlling your dry fly on the water is a skill that can be learned through more advanced casts and it makes a difference. 
It can also make a difference in nymphing with a strike indicator, although in most cases you’ll be more connected to a nymphing presentation with a Euro-Tight Line method on this water. And with a Tight Line Mono Rig (Euro) casting skill itself is not highly important, but other elements require a learned touch that can be perfected with practice easier than making a 40 foot reach cast from river left. 
Any second now the lake run Bull Trout will be arriving to the middle river. If not already there in low numbers. 
The next several months are a great time to fish for big Bull’s. 
And, while I already mentioned above about Golden Stones, I will say again that the 4th of July is when we always really get excited for the hatch to become earnest. And who doesn’t like an earnest bug? Get your Clarks Stones and Norm Woods tied up, or stop by the shop and buy a few fresh ones for the next stomp up river. 
A few nymphs to tuck in the box for the week are a Jigged 20 Inchers, an Olive Perdigon with an Orange Hot Spot, Tan Caddis Pupa (right now we have the original Fat Ass Caddis in stock and we are are waiting for 50 dozen of my pupa to get shipped), Golden Stones, Soft Hackle PT, Fire Starter, Micro Mayfly, 2 Bit Hooker and Red Copper John are all examples of nymphs we recommend from FFP this week.
