JULY 17, 2017

Middle Provo

Fishing is awesome right now! The flows are down to 380 cfs, which is a great flow and there are a plethora of bugs out on the water. The Green Drakes are still out (although they are hit or miss) and the fish are definitely keying in on them if they are around. Just have a few patterns handy in case you stumble upon the hatch. There are also PMD's and Caddis out and the Caddis are growing more and more in numbers. So there are several options out there for you to try and get them on. If there aren’t any noses up then throw on a nymph that imitates one of those bugs and you should get them on that.

Flows

The flows are down to 380 cfs, which is a great flow for all types of fly fishing.

Lower Provo

Fishing has been really good on the lower. The flows are sitting at around 515 cfs, which is a good flow for the river. It will still be tough to wade across in many spots. Look for the wider flat water if you’re looking to cross over to the other side. The fishing is similar to the Middle Provo with PMD's and Caddis hatching. You should see plenty of fish rising, but if you don’t or nymphing is your game, then that will work really well with a Caddis larva, Pheasant Tail, Prince Nymph, PMD Barr's emergers, and split case PMD's.

Flows

The flows have dropped a bunch and are currently at 233 cfs, but the water will be a bit higher than this below the spillway. This is a great fishing flow.

Weber River

The Weber is in great fishing shape and has been flowing around 200 cfs for the last little while, but as of today it took a major dip in the flows and is at 87 cfs, which isn’t normal. I wouldn’t expect that to last very long, so just be sure to keep an eye on the flows before you head out there. The PMD's, Caddis, and Stoneflies have started showing up and fish are just now starting to key on them on top of the surface. If there are no risers, then you should have success nymphing with PMD's, Caddis nymphs, and Sow Bugs.

Flows

The flows were sitting at 200 cfs for a while but dipped down to 87 cfs today, which is really low. This shouldn’t last very long, so just check the flows before you head out.

Green River

I was just up on the Green for a few days last week and it was fishing really well! The flows have finally dropped down to around 2300 cfs, which is an awesome flow for the river for wading and fishing from a boat. There are a few different hatches going on right now, but the most prolific was the Yellow Sallies. It looked like it was snowing because there were so many of these whitish fluffy bugs flying around. It was amazing! The fish are obviously keying on those as well as some Caddis and PMD's. Some days the Caddis outfished the Sallies even though there were many more Sallies flying around. We were also able to get a few to come up for some terrestrials, so throw on an ant, beetle, cricket, or hopper and try to entice one up to eat one of those bigger bugs. If there aren’t too many fish rising, then try a dry dropper from a bigger terrestrial down to an Iron Sally, PMD split case or pheasant tail and you should get some that way.

Middle Provo

Fishing is on! The Middle Provo has finally started to drop and is sitting at 600 cfs, which is a great flow. Wading is now an option with these lower flows — and it’s a breath of fresh air. Now you will be able to access many more areas and pick off fish rising to the surface on the other side of the bank. More and more bugs are starting to show up on the river as well. Be ready with some PMD's and some yellow stoneflies. If you’re lucky you will catch the Green Drake hatch on the middle, which could start popping any day now. The fish gorge themselves with these giant bugs. If dry fly fishing isn’t your thing, then nymphing will always work, and is very productive right now.

Lower Provo

The Lower is starting to get in good shape for fishing. The flows have dropped a bunch and are currently at 233 cfs, but the water will be a bit higher than this below the spillway. This is a great fishing flow and of course when the fishing starts to get good, so do the crowds of tubers floating the river. Start working on your ninja skills so you can dodge the tubers coming right at you. Aside from the tubers, everything is shaping up quite nicely. There are more and more sightings of PMD's and Caddis so be sure to come equipped with a few different patterns and sizes of these flies. If you’re not seeing any risers coming to the surface then don’t hesitate to throw on a nymph. A caddis nymph, split case-PMD, and a big stonefly are all good options for nymphing right now.

Weber River

The Weber is in great fishing shape right now. It has been consistently flowing around 200 cfs for the last little while but that could change, so just be sure to check the flows before you head out. The PMD's, Caddis, and Stoneflies have started showing up and fish are just now starting to key on them on top of the surface. If there are no risers, then you should have success nymphing with PMD's, Caddis nymphs, and Sow Bugs.

Green River

The Green is still fishing well, but they fish are getting a bit pickier since the flows have been consistently high at 8600 cfs for the last few months or so. Last I heard, the flows are supposed to go down around July 5th to around 2400 cfs, which means the dry fly fishing will be epic! Plan a trip to get up there now because the fish will start going crazy for dries once that water drops. There are Caddis out right now, but not too much action on the surface due to the high water, so if you throw on a caddis pupa and nymph, you should see success. The Yellow Sallies should start popping as soon as the water goes down and the fish go crazy for them! Overall, things are starting to look really good for the Green River, so start planning your trip to get up there soon!

Flows

The Green River is currently flowing at 8600 cfs but should be dropping about 1000 cfs a day starting on 7/5 until it gets down to around 2400 cfs.

Flies

  • Elk hair caddis size 16-18

JUNE 19, 2017

Middle Provo

The flows have started to slightly go down which is much better than trending upwards! However, they are still really high at 1260 cfs! Fishing is tough due to the higher flows and limited places to fish, but if you stick to the banks, pocket water, back eddies, or any slower water that you see, you should have some success. Caddis have started to make some appearances and they will be in full force soon, so be sure to have a few patterns ready for that. Hopefully these flows will continue to go down because there are several other bugs knocking at the door and once the flows stabilize, you will start seeing some Green Drakes and PMD's. Make sure you are ready with all of these different bugs in your fly boxes just in case you hit the beginnings of one of these hatches. If you’re out during the high water, then throw on a worm or stonefly with some weight to it trailed by a smaller fly like a caddis, pheasant tail, or sow bug and you should get some action.

Flows

The flows have started to slightly trend downward, which is a good sign, but they are still at 1260 cfs as of today. That is a pretty high flow, so be cautious and stick to the banks and edges of the river.

  • Pat's rubber legs size 12-14
  • Sow bugs size 16-22
  • Zebra midge size 20-24

Lower Provo

Flows have been dropping a little bit and are at 837 cfs as of today. Hopefully they continue to drop so that more water can be accessed. This is a fishable flow, but it’s still a bit high. Just focus on any slower water like the banks and edges. With this higher water, it’s more productive to fish heavier nymph rigs that will get down to the bottom quickly. Put on a Pats Rubber Leg or a heavier worm pattern and trail it with another smaller nymph like a sow bug, zebra midge, or pheasant tail. If streamers are your thing, then put on a nice weighted one and huck it out there! You'll get some chasers in the slower water.

Flows

The flows are sitting at 837 cfs as of today, but its still really high and fast. Just be extremely careful and don’t even think about wading into the river. Just stay on the edges. That is where the fish will be anyway.

Weber River

The flows have finally started going down a little bit on the Weber, but they have been really inconsistent so be sure to check them before you head out. They were sitting at 1100 cfs, which is extremely high for the Weber, then dropped down really low. They are now sitting at 540 cfs below Rockport, which is fishable but still high. There are Caddis starting to show up on the river, which is one of the best hatches to fish on the Weber. You may see some in the morning but I’ve seen more later in the afternoon and they last until the sun starts going down. If you don’t see any trout rising for Caddis, then don’t hesitate to throw a worm pattern trailed by a Caddis nymph, or Sow bug with some weight to it so that it gets to the bottom quickly.

Green River

Flows bumped up today to 8600 cfs and last I heard, they are planning on keeping them at that flow for the rest of the month. This makes it tough for wade fishing, but fishing from a drift boat has been and will be great! The cicadas are out in full swing and are fishing well. If you've never experienced the cicada hatch on the Green, then you need to get up there before they’re gone! There is nothing like throwing a size 8 dry fly and watching a trout rise to it. It is amazing! If dry fly fishing isn’t your thing, then nymph fishing has been awesome with the higher flows. A wire worm or squirmy wormy, with a scud or grey soft hackle trailer has been the ticket. There has also been some BWO's around, so you may see some fish rising to those in some of the slower pocket water. All in all, fishing has been great on the mighty Green River, so get up there!

Flows

The Green River just got bumped up to 8600 cfs and will most likely remain at this flow for the rest of the month. Dry fly fishing and nymphing have been excellent.

JUNE 6, 2017

Middle Provo

The flows just bumped up again today to 1710 cfs. This flow is not fishable, and I would advise you to find somewhere else to go fishing as long as these flows stay up this high. Last week they sat at around 850 which was actually a pretty good flow, so they could move back down again. They have been fluctuating from week to week and sometimes day to day so just be sure to check the flows before you head out if you’re looking to fish the Middle Provo. I went out last week and it fished pretty well, so if the flows drop back down, then throw on a worm or stonefly with some weight to it trailed by a smaller fly like a caddis, pheasant tail, or sow bug.

Lower Provo

The Lower seemed to follow the lead of the Middle Provo. Flows bumped up today to 1040 cfs. These are pretty high flows for this river. As I’m sure most of you have heard, three people lost their lives last week on the Lower Provo. So be smart and careful and stay away from the higher flows until they go down some. If the flows go down a bit then stick to fishing the banks and slower pocket water. With the higher flows and dirtier water, use worm patterns like the San Juan, Wire Worm, or Wiggle Worm and trail one of those with a caddis, pheasant tail, or sow bug. You can also throw big weighted streamers that will get down quick. Just be safe out there and don’t try to wade in the water.

MAY 22, 2017

Middle Provo

The Middle Provo is flowing at about 900 cfs as of May 22nd and has been at about 1100 to 1000 cfs for the last week. This is pretty high for the Middle Provo, but it is still a fishable flow. You may just have to stick to fishing the banks and pocket water. As for the fishing goes...it's tough. With the higher dirtier water, your best bet will be to nymph or throw streamers. These higher flows will flush out lots of worms, so put on a San Juan Worm, Wire Worm, Squirmy Wormy, whatever you choice of worm pattern may be with some good weight to it and follow that with a caddis, pheasant tail, or sow bug. You could also try throwing a heavier streamer. With the dirty water, fish something really bright or really dark so that the fish can see the silhouette of the fly. Whatever your choice may be, just stick to the banks and slower water. DON'T try wading in these flows and BE SAFE!

Flows

The middle provo is flowing at about 1000 cfs, which is a bit high, but fishable. I would suggest checking the flows right before you go out though since they have been fluctuating a bit Just stick to the banks and slower water and DON'T try to wade in these flows.

Lower Provo

The Lower Provo River hasn’t been fishable for the last week or so due to the extremely high and unsafe flows. They were flowing at 1700 cfs up until 5/19 and have since dropped to about 1000 cfs, which is still really high. You can get away with fishing in this flow though. You will just need to stick to fishing the banks and slower pocket water. Fishing the lower will be the same as fishing the middle. With the higher flows and dirtier water, use worm patterns like the San Juan, Wire Worm, or Wiggle Worm and trail one of those with a caddis, pheasant tail, or sow bug. You can also throw big weighted streamers that will get down quick. Just be safe out there and don’t try to wade in the water.

Flows

The Lower Provo flows have been tough to predict. They have been fluctuating a ton and there seems to be no rhyme or reason as to why they are changing them so often. They have been sitting at around 1700 cfs for the last little while, but have recently gone down to 1000 cfs, which is still a high flow. Just be sure to check the flows before you go out.

Weber River

The Weber River below Rockport Reservoir is fishing pretty good, but is flowing a bit high. The river has been fluctuating quite a bit and there’s no telling what’s going to happen with the flows. As of right now, they are at 200 cfs and have been at that flow since 5/19. The Mothers’ Day caddis have started to make some appearances and there are still midges out. So if you see any fish rising to the surface then thats what they will be keying on. If you want to throw dries I would recommend fishing a double dry fly rig and put a larger caddis (size 16 or 18) as the lead fly and tie about 18 inches of tippet off the lead, to a smaller caddis or midge as the trailer. You can also fish this a dry dropper and put on a caddis dry fly as the lead fly and put on a caddis nymph or midge nymph about 18 inches below. The fish will definitely chase a streamer and, of course, nymphing will work as well. Worm patterns are working great right now with the higher flows. I would suggest fishing a worm as the lead fly, followed by a sow bug, caddis, or pheasant tail. Focus on the banks and calmer water or pocket water behind boulders.

Flows

The Weber River is running at 200 cfs as of today, which is a fishable flow, but the river has been fluctuating at random, so just check the flows before you go out.

Green River

The Green has been flowing at max capacity for the last few weeks, but just went down to 6600 cfs. Last I heard, the flows are going to go back up around 9000 cfs on 5/25, so just keep an eye on that if you’re planning on going up there. Fishing has actually been really good. Wade fishing isn’t much of an option at these higher flows, but floating out of a drift boat is very productive. Most of the guides are fishing deep nymph rigs with midges, grey soft hackles, WD40's, and various Worm patterns. There has been some Cicada activity, but no crazy hatches with those yet. It could happen this week or next with the warmer weather kicking in though so stay tuned! Look to the slower pocket water and back eddies if you’re looking to throw some dries. On a heavier note: A few boats have sunk over the past few weeks in the higher water, so its probably wise to go with a guide who knows how to row the river in these flows. Stay safe out there!

Flows

The Green River is currently flowing at 6600 cfs, which is a good flow. I heard they are going to go back up around 9000 cfs on 5/25 though, so just keep an eye on that if you’re planning on going up there.

MAY 5, 2017

Middle Provo

The Middle Provo just got bumped up to 650 cfs as of May 5, 2017. That’s quite a jump from the previous flows and it usually takes the fish a few days to acclimate to these flows, but by now they should be good. These flows are fishable, but getting across the river is going to be difficult. You may just have to stick to fishing the banks and pocket water. As for the fishing goes...The Mother’s Day caddis are starting to pop and the fish are definitely keying on these bugs along with some Skwalas, BWO's and Midges. Whether you are nymphing or throwing dries, it would be wise to have a few different patterns of each of these bugs to throw at the fish. They have been a bit picky, so if you’re not getting any hits, then change up the pattern and continue to do so until you find the right one. If you're giving them good presentations, then you should know pretty quick whether they are into that specific fly or not. Something worth trying is to fish a dry fly Skwala (size 12) and trail it with another caddis or midge dry fly or nymph about 18 inches behind or below the Skwala. On sunny days, I would advise you to fish lighter tippet such as 6x when fishing dries. Just remember to go easy on your set so you don’t lose your fly and the fish. Don’t hesitate to throw a streamer or nymph rig if you're not seeing any noses up. The trout are constantly on the hunt for a bigger meal to help fatten them up early in the season, so don’t be afraid to huck some big meaty articulated streamers. If nymphing is your game, then look for the faster riffly water and pools below these faster waters where the bugs are being dumped off into.

Flows

The Middle Provo just got bumped up to 650 cfs, which is a bit high, but fishable. You may need to stick to the banks and slower water though.

Lower Provo

The Lower Provo is fishing similar to the Middle Provo, but there are more BWO's and less caddis than the middle. You will have your best days when it is overcast and on the verge of raining. Just come prepared with various patterns of midges, BWO's and Caddis. The last few weeks, the fish have been a bit picky with patterns and sizes, so try out a few different ones and it shouldn’t take too long to figure out which ones they are diggin’. If you’re still not having success then try fishing a smaller sized fly and tippet. This could make all the difference. Don't hesitate to throw some big streamers or nymph if you're not seeing much activity on the surface. The flows have been fluctuating quite a bit but they are currently at 436 cfs and are still fishable. Just be sure to check them before you head out because of how unpredictable and frequent they have been changing. Lastly, take advantage of this time of year to enjoy the river in silence (no screaming tubers or floatzillas bombarding the river).

Flows

The Lower Provo flows have been tough to predict. They have been fluctuating a ton and there seems to be no rhyme or reason as to why they are changing them so often. They have been sitting at around 530 cfs for the last little while, but have recently gone down to 436 cfs which is a pretty good flow. Just be sure to check the flows before you go out.

Weber River

The Weber River below Rockport Reservoir is fishing pretty good. The Mother’s Day caddis have started to make some appearances and there are still midges out. If you want to throw dries I would recommend fishing a double dry fly rig and put a larger caddis (size 16 or 18) as the lead fly and tie about 18 inches of tippet off the lead, to a smaller caddis or midge as the trailer. You can also fish a dry dropper and put on a caddis nymph as the lead fly and put on a caddis nymph or midge nymph about 18 inches below. The fish will definitely take a streamer or nymph, if you’re not seeing any activity on top. Focus on calmer water or pocket water behind boulders. Sow bugs are always a good call on the Weber, so if nymphing, fish a sow bug and a midge or prince nymph together.

Flows

The Weber River is running at around 130 cfs which is a great flow.

Green River

The Green is basically flowing at max capacity right now, however fishing has actually been really good if you are nymphing. Wade fishing isn’t much of an option at these flows, but floating out of a drift boat is very productive. Most of the guides are fishing deep nymph rigs with midges and grey soft hackles or WD40's. There are fish still rising in these high flows for BWO's and midges, but you would need to look to the slower pocket water and back eddies if you’re looking to throw some dries. A few boats have sunk over the past few weeks, so it’s probably wise to go with a guide who knows how to row the river in these flows. Stay safe out there!

Flows

The Green River is flowing at around 9020 cfs, which is really high! However, as mentioned in the summary, fishing has been really good as long as you're fishing from a boat.

  • Mother shucker size 20-22
  • Griffiths Gnat size 18-22
