September has been a wild ride so far. One week we're sweltering in the 90s, the next week we have 3-4" of snow in the high Uintas! We need the water, however, and I know our fish have appreciated the cooler temps and rain we've had the last couple of days. September is and has always been a transition month; our summer hatches are winding down, and our fall bugs haven't quite started. In short, it's time to head out with both big and little bugs in your boxes. We have some great resources to stay up to date on water conditions around the state, so please use them to plan your fishing trips. Even though the high mountains got snow, there are still plenty of fishing opportunities in the Uinta Mountains. Time to get out and explore!

Fishing Conditions Summary:

Flows out of Jordanelle Reservoir are now 274 CFS.  This is still a lower flow than I would like to see, but it will make for easier wading. This lower flow will make the fish want to seek out deeper slots and holes, and the sunnier weather will make the faster pocket-water a good option to fish; especially during the middle of the day. The Lower Provo has dropped in flows, and is now flowing at 388 CFS. This drop in flows will make the Lower another option to go fish, but it will also make the fish want to seek out deeper water and structure. The flows out of Flaming Gorge Reservoir are bumping between 1,500 CFS-2,200 CFS. It is always smart to check the flows before you go out to Dutch John, especially this time of year. The Weber River below Rockport Reservoir, as of today, is flowing at 180 CFS. The Weber just below Echo Reservoir is now flowing at 258 CFS. This makes both the middle and upper-lower sections Weber good options to go explore.

 

Middle Provo:

Flows on the Middle Provo have been holding steady at 274 CFS. Keep in mind, however, that they pull water out of the river a mile or two below Jordanelle at the diversion dam; so flows below the diversion will be lower than those above it. As far as where you should look to fish, it is all about time of day. The obvious looking deep holes and runs have fished better during the mornings, evenings, and if/when we get cloud cover. Our Middle Provo fish will seek out deeper, faster, more oxygenated water during the heat of the day. So, don't overlook any fishy pocket-water! With the changing of the seasons, it would be wise to make sure you have your midge boxes with you. Midges typically hatch/lay their eggs in the mornings and evenings, and the fish will definitely be looking for them more and more. I would also still expect to see sporadic caddis activity in the mornings and evenings-especially up closer to Jordanelle Reservoir. The cloudier days have been creating better hatch conditions, and this time of year we can still see PMDs hatching, and the start of our Pseudocloeon Mayflies (Micro Baetis). Terrestrial flies such as ants, beetles, crickets, and hoppers will become very important to the fish as the grass continues to dry out. The hotter and drier the weather is, the closer these insects will migrate to the edge of the water. The windier the day is, the more likely these insects will get blown out of the grasses and trees-making terrestrials a viable food option for any opportunistic trout. 

 

Lower Provo:

Lower Provo flows are now at 388 CFS. With school starting up, and the weather cooling down, the tuber/raft traffic during the weekdays should slow down a little, which will make fishing the Lower more enjoyable. At these flows the fish will still usually hold closer to the banks, and around any form of structure (rocks, logs, seam lines,etc.) they can find. If you check it out, make sure you have Sow Bugs, a variety of small midge larva, pupa, and adult patterns, smaller PMD nymphs and dries, small Baetis nymphs and dries, Ants, Beetles, Hoppers, and all stages of Caddis. If all else fails try using flashy streamers to move some fish.

 

Weber River:

The Weber between Wanship and Coalville is, as of today, 180 CFS. This flow makes fishing between Rockport and Echo Reservoirs a good local option to check out. Expect to fish Midges (#18-#24), Micro Baetis (#20-#24), left over PMDs (#18-20), Caddis (#16-#18), and terrestrials throughout the river corridor. The Weber directly below Echo Reservoir is now running at 258 CFS. Down by Mountain Green and Ogden has also dropped, but it is still a pushy flow, so use caution.  Good Weber River flies to have in your boxes for this time of year are smaller Baetis nymphs, Caddis larva, Caddis Dries, Zebra Midges, Sow Bugs, Hoppers, and streamers in various sizes and colors. 

 

Green River Below Flaming Gorge:

The flows out of Flaming Gorge have been fluctuating between 1,500 CFS-2,200CFS. They have been doing this for a while, so the fish should be used to bump, and fishing shouldn't be negatively affected by it. If you are looking to fish dries over on the Green for the next month or so, I would highly recommend bringing a variety of terrestrials (Ants, Beetles, Crickets, Hoppers) with you, some smaller caddis, and also some very small mayfly nymphs, duns, and spinners. Like many waters across the west, September signals the arrival of our first small bugs of fall. The Green will see hatches and spinner falls of Tricos and Psuedocloeon Mayflies for the next couple of weeks; especially in the slower river sections and back-eddies. These little insects can bring about some fun fishing opportunities that will test your skills and patience, but if that's not your game, searching with a terrestrial-dropper rig can also be effective. The cooler weather of fall can also trigger the start of some very good streamer fishing, so make sure to bring your streamer box with you if you head east! 

 

Other Waters:

Even though the high mountains got some snow this week, the lakes and streams along the Wasatch Front, Uintas, and Boulder Mountain range will be still good options to go explore for the rest of the fall. Fish should be cruising the edges and hungry in the mornings and evenings, so if you're looking for a change of pace, take a handful of various attractor wet and dry flies, and go on a exploratory trip and see what you can find.

 

Fishing Tip:

We've had a lot of anglers telling us that terrestrials aren't working very well on the local fisheries; despite there being a lot of grasshoppers, ants, and beetles around. There is a simple explanation (or two) for this, and it starts with location. A fish looking for a terrestrial to fall in, usually holds very close to the river bank. If you are fishing where there are a lot of anglers stomping up and down the river bank, you most likely won't find a trout there for long. Look to take a walk into the less traveled areas of the river corridor, and DON'T tromp down the river banks! Be sneaky, approach from behind, and if a spot looks fishy, get your flies as close to the bank /structure as you can. Another factor that helps fish get on terrestrials is hot, windy weather. Terrestrials love hot weather; it makes them more active. The more active these insects are on a windy day, the better the chances are of them falling into the water. Last tip for fishing terrestrials: Keep your feet moving! Get some good casts/drifts in a likely looking spot. If nothing happens, move on. The more water you cover, the better your chances are of finding a happy fish. 

As far as my go to leader/tippet choice for this late-summer/early-fall season, I'm still running a 7.5' 3X leader, and I carry tippets from 3X-6X. I find that using a short, stout leader like this allows me to fish streamers and hopper-dropper rigs, but also allows me to adjust to fishing a variety of smaller flies with a simple tippet adjustment. With the increasing heat and fishing pressure, it would be wise to sneak up to the high country in the Uintas and Boulders to find happy fish and solitude. Get out there, explore, be safe, and have fun!
