Tuesday 9/2/25 Farmington River Report: Flying Ants & Flow Cut

Store Hours:
Store hours currently are 8am-6pm Monday & Tuesday, closed on Wednesdays, 8am-6pm Thursday & Friday, and 8am-5pm on Saturday & Sunday. 

Pictured up top is 
Zach St. Amand’s client Randy with a beauty of a brown trout. Big trout have been tougher to come by lately, but the local guides know how to get it done. 

Tom Ames new & updated "Pocketguide to Eastern Hatches" books arrived last week, even though the official “release date” is mid September and you cannot purchase it on Amazon until then. We sold through all 50 copies we ordered already, but we should have 50 more copies in time for the upcoming weekend. This is the BEST hatch guide for our area, nothing else comes close. This version has some new info, new pictures, and new fly patterns. We will do our best to try to keep this in stock. 

Nymphing Tip
Small nymphs are often the
key to subsurface success in the late summer/early fall, and by small I mean #18 and smaller, all the way down to #22-24. Exceptions would be Isonychia #10-14, and Stoneflies #8-10. Most nymphs are small to very small this time of year. And they are by far more numerous than bigger ones. Some days this makes a huge difference. I know a guy from PA that catches an average of 6,000-8,000 trout every year. Yes, he is retired and fishes a LOT (about 300 days a year), but usually only part of each day. And yes, he’s a highly skilled nympher with excellent water reading skills, and he lives near the best streams in central PA (2,000 - 4,000+ fish per mile for some of his streams). If he has a secret, it’s that he mostly fishes nymphs averaging #18-24 on a Euro Mono rig (FYI he also does dry flies & dry/dropper). He typically uses a 4x micro leader and 6x tippet with 2 flies. He reasons that immature nymphs are small and grossly outnumber bigger adult nymphs, and it’s hard to argue with his results. 

As of 9/1/25, the entire upper 21 miles of the Farmington River from the dam in Riverton downstream to the Rt 177 bridge in Unionville goes Catch & Release until 6am on the second Saturday in April 2026. If you fish downstream of the Rt 177 bridge you can keep 5 fish 9" or larger through the end of February, then it also goes C&R until the second Saturday in April. If you see anyone illegally keeping trout, call the 24/7 turn in poachers DEEP hotline at 860-424-3333. Even if they cannot send somebody in time, they still log the call and it helps us get more future enforcement. 

Frabill landing nets are in stock
! Very functional lightweight nets with rubber coated mesh, and can handle very big fish. Flat net bottoms make it easy to deal with the fish and unhook them without the fish being all bent up. These nets are very popular with the competition guys. A great value at $40 to $55, depending upon the size. 

We have a small batch of the new Diamondback Gen IV Nymph Rods with carbon grips- the previous batches were all with traditional cork grips. Carbon grips are more sensitive than cork, as well as quite durable (they won’t chip like cork can). There is a $25 upcharge for the carbon handle. We got them in the popular 10’ 7” #2 & #3 rods, and the 10’ #2. We can order the carbon grip in any size rod you want though.

The store is stocked with tons of books at the moment, both used & new books. Also, lots of used rods & reels currently.

Diamondback Generation IV Euro nymphing rods are available.
 We have the full line-up, minus the 10' 7" #4 (not available yet, probably mid fall). The models we have include 10' and 10' 7" lengths in #1, #2, #3, and 10' 7" in #6 & #7. These rods are very nice with crisp, responsive tips that recover fast with minimal wobble. The 10’ 7” #1 is a very interesting and excellent option for Micro Leaders, lighter tippets (6x and thinner), and lighter flies (2-3mm)- the rod has more backbone in the lower half than you would expect, while having a very soft tip. The 10' 7" #2 & #3 have been the big sellers for us, perfect for the Farmington River. The #3 is the all around and will do everything, but the #2 is great if you fish mostly 6x, throws lighter flies a bit easier, and is slightly better with Micro Leaders. The 7 weight is a new addition to the Diamondback lineup, for those targeting larger Steelhead with heavier tippets, as well as King Salmon and other larger fish where you need a stiffer rod with some serious backbone. The 6 weight is probably overall the better choice for Salmon River Steelhead in NY, where you are often down lighter 3x & 4x tippets and still need a rod that has some backbone to land 10# plus fish, but has a softer tip so you don't break fish off. 

Tuesday afternoon 9/2/25 River Report:
Back to reality after the long holiday weekend. There were tons of Flying Ants out yesterday (Monday, Labor Day), especially from mid afternoon through early evening. They were about a #16-18. This morning I had reports of #24 Flying Ants. September is typically the big month for these bugs. Warmer, humid days are typically the best, and if there is rain the day before, that’s even better. They are not 100% predictable, but when these Ants hit the water, they trout go a bit crazy. All the food is on the surface, so the trout have to rise to eat them. Make sure to have some with you from #18-24 this month. The conditions this week look suitable for more Flying Ant mating swarms. 

Looks like they did about a 55cfs flow reduction this morning. This puts the total flow in the Permanent TMA/Catch & Release down to 174cfs, with 164 cfs in Riverton, and the Still River adding in 10cfs below that. We could use some rain. I would call this level medium-low to moderately low. While this will reduce the holding water and make the trout spookier, it will also make it easier to figure out where the trout are and also increase the amount of fish feeding on the surface when there is a hatch. Long leaders (12’ plus), lighter tippets, and smaller flies are all a good idea.

Morning Trico spinner falls are still going on, albeit the hatch is moving upstream and the hatch density is lighter and it is mostly smaller fish rising to them, with some exceptions. Make sure to go small enough, as in #24-26 patterns, fished on a long leader with a long 7x tippet. Also seeing decent numbers of small Caddis averaging #18-22, in assorted colors like gray, tan, and black. You will see the black caddis adults on the rocks, they are hard to see on the water. FYI splashy rises generally means Caddis. Isonychia can also create aggressive rises. They typically hatch in fast water between late afternoon and dark. They have been light in numbers, but this cooler weather seems to be helping.

It
was 60 degrees for a water temp behind UpCountry this morning, peaked out at about 63 degrees on Monday. Riverton water temp was about 61 degrees at the Rt 20 bridge (Hitchcock/Riverton Self Storage) this morning, it peaked at 62.5 degrees Monday afternoon (cooler, cloudy day). Lower flows (due to the 55cfs flow cut) and slightly warmer weather this week (highs 76-79 through Saturday) will push water temps up a little bit, but for the most part we should be okay. Use your thermometer if you are not sure about the temps, and look for water 68 degrees or cooler, and preferably 65 degrees or less for better fishing. If water temps are too high, keeep moving upriver until you find suitable temps. You can start further downsteam in the mornings, but depending upon how far downriver you are, you may need to move upstream by noon.

Late morning through later afternoons
had been relatively quiet in terms of hatches, but with Flying Ants on the menu for September, afternoons can be good. Also keep your eyes out for #10-14 Isonychia hatching in the faster water between late afternoon and dark. It’s a sporadic, one here and one there type of hatch, but the cooler weather seems to be improving the Iso hatching. There have been a good amount of small Black Caddis averaging #20-22 on the rocks, some small tan (other colors too) Caddis flying around, and the rocks in the fast water have a good number of large Stonefly shucks on them, also some Yellow Sally Stoneflies on the rocks. There is a mish mash of various insects at dusk, including some bigger #12-14 Light Cahill/Summer Steno’s and small assorted Caddis #18-22. Mornings with large #8-10 Stonefly nymphs is a good strategy for bigger fish, think first light (5:45am) to about 10am’ish. Fish the faster water- pool heads, riffles, runs, and pocket water. 
 

Seems like the August Trico spinner falls were the best hatch this year despite mostly mediocre big activity in 2025. Remember that it’s mostly about the spinner fall, and that is triggered by air temps in the upper 60’s (about 68). Trout seem to be preferring tiny Trico dries in the #24-26 range, 22’s are mostly either not getting a look or getting refusals. Cool nights will push the spinners later in the morning, and warm night will push them from mid morning to very early morning. Nymphing the faster water with small nymphs & Junk Flies is also working. Also big Stoneflies, mainly in the mornings when they are most active, and larger Iso type nymph from about mid afternoon through dusk. Seeing big Stonefly shucks all over the rocks in fast water lately, which is a great sign. FYI also seeing Yellow Sally Stonefly shucks on rocks recently, they typically run #14-20. Sallies are mostly a nymphing deal, and they are a common bug here in August & September.

If trout are not rising, be prepared to go subsurface and fish the faster water. If you hate nymphing, try Dry/Dropper or fish 2-3 wet flies/soft hackles. All effective summertime strategies. You can also blind fish dry flies (attractors like Stimulators/smaller Chubby Chernobyls, bigger dries like Isonychia, or terrestrials like ants & beetles) in broken water, it’s surprisingly effective this time of year. You can do Dry/Dropper and attach a small lightly weighted nymph 18-24” below your dry to really increase your odds of success.

Hatches continue to overall be light this year, with the river above the Permanent TMA/Catch & Release seeing more consistent bug activity on average, especially in the typically slower late morning through late afternoon time slot. Hotter days will tend to push the bugs to either early or late, and cooler/cloudy days will see the morning fishing go later, and the evening fishing start earlier. Hatches have been very hard to predict this year. Right at dusk to dark has been a fairly consistent peak hatch time, and during the daytime the upper river (Campground & up) has been the place to be. If you leave before full darkness, you may miss out on a brief but very good window of dry fly fishing. Some nights it’s only 15-30 minutes and happens just as it’s getting dark. Other specific predictions have been harder to make in terms of what bugs will hatch where & when- you just need to be observant and match what you see.

Check different river sections out when the fishing & hatches are slow. Fish in the shade whenever possible, trout will often move into those areas. When bug activity is light to non-existent (not uncommon, especially midday), the high percentage techniques are nymphing, dry-dropper, wet flies/soft hackles, or blind fishing attractor/bigger dries & terrestrials. Beetles & Ants are great for the non-hatch times in the summer, very effective. Look for shady areas. Don’t waste your time trying to force feed hatch-matching mayflies when they are not on the water and/or the trout are not rising. Isonychia are definitely an exception, you can blind fish #10-14 Iso patterns in riffly water and do well. Blue Winged Olives (Olives/BWO’s) can run as big as #18, but I’d expect to see more smaller ones in the #22-26 range. Match the size closely. Overcast days are best for BWO hatches.

Glad to see we’ve mostly stayed out of a drought so far in 2025, and there is plenty of water in the reservoirs currently CT DEEP has a flow plan for the Farmington River, and the target release from Colebrook River Lake Dam is 250cfs for August (assuming normal precipitation/resrvoir levels)- this is a target flow number, and not an absolute. For September the target dam release is 200cfs. During dry periods this would be reduced, especially if the lake level is too low. If we get lots of rain it’s increased if the lake level is too high. They also sometimes temporarily bump it up extra during heat waves to cool the river down. So far they have been on the conservative with the releases, with the fear being if they draw the reservoir down too much and then we end up in a drought, that we could be in bad shape in late summer/early fall and not be able to let out enough water. DEEP has done a great job managing the flows since they took over in June 2024, and it should only get better as they gain experience.

Nymphing is a mainstay right now, especially in the late morning to early evening time slot when hatches are scarce.
A great summer tactic is to target the first light (about 5:45am) to the mid/late morning time period in fast water with large #8-10 Stonefly nymphs. The naturals crawl out to emerge at that time of day, and some of them get knocked into the drift. Pair them up with a smaller nymph, something like a Caddis pupa, Walt’s Worm, or small Pheasant Tail/Frenchy. The fast water at pool heads and in between pools is loaded with trout. It’s also more oxygenated and holds more bugs. Mousing after dark for big trout is popular in the summer, and an especially good choice when it’s really hot during the day. A lot of the biggest trout become mainly nocturnal in the summer.

There are some Isonychia hatching in the fast water, they have been light in numbers overall. Having said that, it doesn’t take many Iso’s to get the fish on them. Caddis have been a common bug, with the best action in the mornings in faster water, and right at dusk and even beyond into the dark. Most (but not all) Caddis are on the smaller side lately, like #18-22. Be prepared to fish subsurface if you don’t have a hatch or rising trout. Caddis pupa (tan, olive/green,) and Walt’s Worms are working well in #16-20, and Pheasant Tails too (#12-
14 for Isonychia, and #18-22 for Sulfurs & Blue Winged Olives/BWO’s). Light Cahills/Summer Stenos #12-14 are a possibility anywhere on the river at dusk. You may see #20-26 Blue Winged Olives, especially on cloudy days.

Summer is a peak time for big Iso’s in the Permanent TMA/C&R. The nymphs can swim like a tiny minnow, so play around with dead drifting, swinging, twitching, and even 6-12” strips like a mini streamer. The trout will tell you what they want. You can use a #12 BMAR Iso nymph, or a Prince Nymph or Pheasant Tail to imitate this bug. You can also blind fish big Iso dry flies in #10-14. They typically hatch between late afternoon & dark, but I’ve also seen them here at other times of the day.

Streamers can be a good option during low light (early/late in the day), or when you have high and/or dirty water. Make sure to get them down, experiment with different retrieves, change colors, and play with different fly sizes & designs (length, bulk/sparseness, shape, etc.). I usually start with a fast strip his time of year. But if that doesn’t work, slow it down, change your presentation angle, swing them, twitch them, fish them on the dangle- experiment based upon the trout’s reaction (or lack thereof lol). Go smaller if you cannot get eats on bigger patterns. Also try trailing a nymph or wet fly/soft hackle about 18” behind a weighted streamer, very effective for converting follows to eats, and a great way to “nymph” if you aren’t proficient at nymphing.

Assorted Caddis #16-22 will be present daily straight through mid fall, and anglers often overlook them because they are so obsessed with Mayflies. Caddis are most active in the faster water: pool heads, riffles, runs, rapids & pocket water. Trout will gorge on the pupa surface, hint hint. Various nymphs from #8-20 are catching fish. Caddis pupa are working subsurface in #16-22 (olive/green, tan). You can use specific pupa patterns, Walt’s Worms, and Sexy Waltz (has flashy rib & hotspot). On crappy, cooler overcast afternoons, we’ve been seeing #20-24 Blue Winged Olives (BWO’s/Olives).

The fast water is currently full of trout, they are literally everywhere. FYI after the CT fisheries sampled the trout population last September (2024), they estimated the trout per mile in the Permanent TMA/C&R at 2,800+ fish- that’s a lot! Tight-line nymphing with one or two weighted nymphs is your best option to probe faster riffles, runs, rapids & pocket water, but Indicator nymphing is effective also. Make sure one of your flies is a pupa-type pattern. Also hard to go wrong with a #16-22 Pheasant Tail or Frenchy (just a hot-spot PT). FYI, small PT’s work 12 months a year and are a great dropper fly when you are not sure what to put on. From May through October, if I’m nymphing, at some point there will definitely be a Caddis pupa pattern #14-18 on my rig at some point.

In case you missed it up top, we have gone to a
6pm closing time on weekdays. Also, we are now CLOSED on Wednesdays at least for a while, so please plan accordingly.

Don’t be afraid to explore and fish new water to get away from the crowds, there are literally fish EVERYWHERE, including all the water in between the pools. You are also more apt to get into wild fish when you fish water that isn’t as busy. Wild fish don’t like being constantly disturbed by anglers. The further you go downstream, in general the less anglers you will see- especially if you walk 5-10 minutes away from the easy access points. Most anglers focus on the famous named pools that have easy access, and skip the water in between. The water outside of the Permanent Catch & Release/TMA gets less pressure for the most part. FYI in the summer, due to water temps you don’t want to go too far downstream or you will end up in water that is hitting or exceeding 70 degrees- USE YOUR THERMOMETER!!!

****************************************************************

Dries:
-Flying Ants #16-24: typically afternoons/early eves, especially on warmer, humid days. A September staple.
-Tricos #22-26: Morning deal, it’s all about the spinner fall- they ball up in the air over riffles and fall to the water when air temps hit the upper 60’s. We are getting toward the tail end of this hatch, it's getting lighter, look more upriver for it.
-Assorted Caddis #16-22 (tan, green/olive, black): Mostly on the smaller side now, various species, especially Black Caddis. Active mostly in the mornings and evenings, nymphing with pupa is currently the most productive tactic for them. They typically egg-lay later in the day in low light, in the faster water.
-Yellow Sally #14-20: Fast water bug, you will see the shucks all over the downstream side of rocks in fast water, look like miniature Golden Stones. Mostly a nymphing deal.
-Blue Winged Olives (BWO’s/Olives) #20-26: afternoons & eves, especially during cloudy, cooler weather. Rusty spinners also in the same sizes at dusk.
-Rusty Spinner #12-26: imitates the spinner of many different mayflies. Most commonly on the water at dusk.
-Light Cahill/Summer Stenos #12-18: evenings
-Isonychia #10-14 light late afternoon to evening hatch in fast water
-Summer/Winter Caddis #18-24: hatch is typically early to mid morning, all year long. Trout focus on the pupa first, and then as the morning progresses they normally switch to the winged, egg-laying adults. July/August are peak months for this morning bug.
-Ants & Beetles #14-20: deadly in the summertime!
-Attractor Dries #10-16: Mini Chubbies, Stimulators, Amazon Ants, etc.
-Mouse patterns: fish after dark for BIG trout, use a short/heavy 0x leader
-Midges #20-28: afternoons/eves


Nymphs:
-Small Nymphs #18-24: various patterns, most of the bugs are small to tiny in late summer
-Assorted Caddis Pupa #16-22 in various colors (olive/green, tan). Use specific pupa, plain Walt’s Worms, Sexy Waltz, Hare’s Ear Blowtorch.
-Pheasant Tails/Frenchies #12-22: imitates a wide range of Mayflies including Sulfurs, Isonychia, Vitreus, Blue Winged Olives, small Stoneflies, and more.
-Blue Winged (Baetis) Olive Nymphs #16-22: all year long
-Big Stonefly Nymphs #8-10: early to mid AM in fast water- golden/yellow, brown, black, Pat’s
-Isonychia Nymph #10-14: mid afternoon through eves, fish in fast water. Use BMAR Iso nymph, Keslar’s Iso, also big Princes & Pheasant Tails
-Yellow Sally Nymph #14-18: fish in fast water, prevalent in August & September. FYI yellow/brown Sulfur Nymphs can also work to imitate them.
-Caddis Larva (olive to green) #14-16: lots of these in the river (most other rivers too), imitates the common Hydrospyche, good all year
-Attractor Nymphs #14-20: such as Sexy Waltz, Rainbow Warriors, Frenchies, Prince, Triple Threats, Pink Bead Walt’s Worm/Pheasant Tails/Hare’s Ear, etc. Often work better than drabber, more imitative flies, even in the summer in low/clear water.
-Cased Caddis #10-16: all year, but especially after rain or flow bumps (higher water knocks them into the drift)
-Winter/Summer Caddis Larva #18 (yellow)- also imitates Black Caddis larva & some Midge larva
-Midges #18-22 (black, olive, red): Zebra Midge, Flash Midge, Red Iris Midge.

 

Streamers:
*We have a lot of new streamer patterns from MT Fly Co in the bins, including plenty of bigger articulated patterns.

***Don’t neglect streamers! - top colors have been olive, tan, white, and black. Black is good on recently stocked trout (especially rainbows), during low light (first & last light), and high and/or dirty water.
-Jigged Streamers #8-12: various patterns/colors, deadly fished on a tight-line/Euro rig, often sorts out bigger fish. Great to use as a clean-up fly after you nymph a run.
-Ice Picks (tan, gray, white, yellow): tied by Rich Strolis, a very nice single hook baitfish pattern
-Woolly Bugger #4-12: assorted colors, try also Don's Peach Bugger
-Zonker #4-6: a classic fish catcher! In white, natural
-BMAR Yellow Matuka #6: deadly fall fly! Also standard Matuka in olive, brown
-Zuddler #4-8: one of our favorites, in olive, white, brown, black, yellow
-Complex & Mini Twist Bugger #2-6: assorted colors, very effective
-Muddler Minnow #6-10: and oldie, but a goodie. Most anglers don’t fish this classic pattern anymore, and that’s a mistake! Quite a versatile fly that can be floated, skated, dead-drifted, swung, stripped, or weighted down & nymphed.
