Don't Match the Hatch, Match the Conditions.

This week I found myself faced with a somewhat unusual situation of not having the right weight of fly to meet my tactical angling needs. I have been dredging the depths of rivers for so long looking for the largest fish a stream might hide that I completely overlooked stocking my boxes with lightly weighted flies. My tactical focus became locked in on presenting heavily weighted nymphs in deep slots and thus ignored having a good plan for low water conditions. 

The Rivers in Western Colorado are currently flowing below average for this time of year. With our rivers so low, the pools that I frequently fish are now shallow, which causes a significant change to the hydraulics. This change in the hydrology moves fish out of the reliable pools and into other locations within the stream channel, generally, in pockets behind boulders or riffles. My attempt at drifting dense stonefly patterns into those locations was an exercise in futility. Fishing densely weighted patterns in shallow water may require more effort in maintaining a good drift, and in fact, it can be tricky.

I am re-tooling many of my favorite spring fly patterns to be lighter to make low water tactical angling manageable. I am tying Perdigon nymphs with smaller than usual beads for gently sinking into shallow pockets behind boulders and soft hackled stoneflies for drifting just above the cobble in riffles. I  even added a few smaller streamers that I can fish with my thirty-foot French leaders.

While it is necessary to match the prevailing benthic macroinvertebrates that are present in your trout waters with our pattern selection, it is also vital to match the conditions as well. This year's low water will require an adjustment in tying lighter weight nymphs, so they will slowly reach the bottom without immediately banging into or getting snagged in the rocks. Brass beads are a lighter alternative to using tungsten beads can offer the solution for this requirement.

Besides bead selection, color is also an essential factor to consider. Somber hued, less flashy patterns are less likely to turn off the fish in low water conditions. Leave the bright hot spotted attractor patterns at home until it rains. Choose materials such as pheasant tail fibers, hares ear fur and partridge. These materials are buggy and dull lending to a natural looking fly. If using reflective materials such as tinsel, do so in a judicious manner. A little glint in a fly pattern can make them more attractive to fish, but just a dash too much can ruin it.

A Spring Fly Box for Out West

IMG_4211.JPG

No task has daunted me more than the endeavor to compile a top ten list of my favorite fly patterns for spring. Spring is the awakening of trout streams worldwide offering a wide array of insect hatches. With so many different hatches occurring from one location to another, no single list could ever be reliable enough to share publicly. My list of top ten fly patterns of spring is entirely useless for someone else in another region of the world encountering different insect hatches.

In the American West, spring wreaks havoc on our emotions. We wake up and look at the weather forecast for a clue to what we might expect that day only to be sucker punched with something entirely contradictory. I have had friends visit in the Spring ask me what clothing to bring while packing. I  always reply, "pack for every season."

Spring mornings may often begin warm and sunny, only to have it snow and hail an hour later, and vice versa.  Our bi-polar weather can interfere with your chances of encountering any of our favorite spring hatches to the odds of winning a blackout BINGO. The key is to plan for anything and everything; be prepared. 

Being prepared is the key to success during the spring fishing season. My spring fly boxes reflect my attempt of being ready for anything. My fly boxes contain medium sized stonefly patterns for imitating later instar juvenile nymphs having not yet reached maturity. Smaller free living caddis larva in green, gray and tan. These same free-living caddis larva will continue to get larger as the season progresses. Midge patterns for matching the spring chironomid blizzards. Various Baetis patterns in case the weather cooperates enough for the Blue Winged Olive's to hatch. Finally, I keep a few caddis emergers and wet fly patterns for matching the Mothers day Caddis hatch

Fly Patterns of my Spring Flybox

Every Fly You Need to Cover Every Important Stonefly

I organize my fly boxes based of the insect species I frequently encounter in the field. Over the years, I have been able to consolidate the number of patterns that I need to carry with me in order to match ALL the hatches I encounter. In truth, I only need to carry a dozen to a dozen and a half patterns to match all the stoneflies including caddis and mayflies everywhere I go. 

I recently updated my stonefly nymph box and made a small chart to ensure that I had the patterns I needed to match all the stoneflies. We may not think to use Czech Nymphs to imitate stoneflies or simple little micro glint jigs, but both can also be useful stonefly imitations. We need only to match the general size shape and color of the natural for success and to have a fly in your box that serves that function.
 

Getting Hitched

Do you ever lie awake at night thinking about all those little ideas churning around in your head? I am plagued with them almost every night. Some ideas are jotted down on a note, and others keep rattling around for years. Like a pestering earworm whose record keeps skipping over that same chorus over and over again in your head, listening to the song in its entirety is said to be the remedy. Chasing a persistent idea just might get it out of your head. Such was the case back in 2004 with the trailer hitch.

My home water for many decades was Oregon's Metolius River. Managed as a wild river the Metolius is for fly fishing only. In addition to being fly fishing only water, regulations prohibit the use of additional weight attached to the fly line or leader. This regulation posed a problem for me, as I discovered that the fish in the Metolius are primarily hiding in the deepest darkest pools and rarely out in the open riffles. Getting my patterns into the depths required copious amounts of weight tied into the fly.

 Newburys Stinger Stone version 2.0

Newburys Stinger Stone version 2.0

The Metolius river has an abundance of golden stoneflies dwelling amongst the cobble and stones. Imitating these large nymphs provides the perfect substrate in which to tie anchor flies for use in the forbidden depths. A 4mm metal bead and 15 wraps of .20 weighted wire were sufficient to bounce bottom in 4 feet deep water. Life would be perfect if all I ever had to fish were this one pattern alone, a fly pattern I developed on the Metolius for getting deep the Stinger Stone.

The Stinger stone was my first pattern that employed the addition of a mono loop in the rear of the fly. In its first incarnation, I did not initially tie the fly as a stinger style pattern, just a bead-headed stonefly on a curved shank grub hook. I found the grub hook to be problematic in that the point was too long and had killed a few fish. Pinching the barbs also caused the droppers I used to slip off the bend of the hook. I had to remedy the hook problem, so I cut off the bend of the hook and added a short shanked egg hook instead. One thing led to another, and I further complicated the pattern for Umpqua Feather Merchants who picked it up for commercial production. After sales declined from a design we all considered a failure, I kept the mono loop and started using it in my other anchor patterns.

Laying the foundation for anchor jigs

The trailer hitch has stuck around in the guiding boxes providing me with a tool in an arsenal of tactics to accomplish a task: fishing a multiple fly rig with a dropper affixed to another fly that will not slip off a barbless hook.

I have had no documented failures in the loop itself breaking or coming untied. The knots are no more vulnerable than any other knot you can use. I once had a commenter on a social media post about mono "cutting" mono. If that were the case, your poorly executed tippet repairs would all fail. No sir, you CAN use a mono loop and not have it fail if you practice good knot tying skills. The only issue that plagues me with the hitch is that I have to check it for fouling frequently.


Here is a post that SwittersB wrote a few years back about the mono loop I use .

You Keep Turning Me Upside Down

I have enjoyed the best summer seasons of my life as a field fisheries biologist collecting data and observing fish and aquatic insects in their natural habitat. In that time, I have snorkeled numerous rivers counting and identifying fish and benthic macroinvertebrates. My most memorable time was watching insects behaving naturally underwater. On a few occasions, I was blessed to have taken a front row seat in witnessing emergence activity and how fish feed during a hatch. In all that time I was underwater, I have seen very few living nymphs drifting upside down for more than just a few seconds in the current. Living naturals of most species of aquatic insects are remarkably adept at remaining in a dorsal up position despite the heaviest of currents tossing them about. If naturals do get inverted, they are quickly self righted through the dorsal light polarization phenomenon. However, giant Salmonfly nymphs are the most prone to prolonged inverted drifts but get soon oriented. More on that later.

 A completely round fly displays the same color and profile despite its orientation in the water.

A completely round fly displays the same color and profile despite its orientation in the water.

I have heard there is a video floating around out there somewhere illustrating jig flies tumbling in the current in all orientations. However, physics will dictate a jig weighted with a slotted tungsten bead will remain in a mostly hook point up position while occasionally tumbling along in the current. This of course depends on current speed, line tension and bead weight.  

Because weighted jigs can be prone to a limited degree of tumbling -- depending on where and how you fish them -- I have gone back to the “tied in the round” philosophy adopted almost a half century ago by Major Charles E. Brooks who also observed salmonflies in the Yellowstone River occasionally become inverted and fish avoiding them. Subsequently, Brooks came up with his tied in the round patterns such as the Brooks Stone Nymph

My pet peeve is focused on perdigon jigs that are tied upside down with the wingcase painted on the side of the fly that is going to drift in a dominant downward position. Brooks observed fish will refuse upside down nymphs (I do not support nor deny these claims). However, It makes little sense and entirely unnatural to me to present an upside down fly to the fish based on my field observations and that of my elders.

To ameliorate my pet peeve of upside down jigs, I have omitted the wingcases altogether and have done away with the issue of fly orientation altogether. Problem solved!
Note: I still use wingcases on non-jig perdigon.

Now, let's talk about all those videos documenting unusual hominids meandering around leaving giant footprints in the woods…

You can read a short info on Charles Brooks in the round philosophy here.

Perdigon nymphs are designed to fish the fast turbulent sections of rivers where naturals are most prone to tumbling. So in all fairness, it doesn't really matter how the fly is oriented as the fish only have an instant to take the fly in water where good hook sets are more likely to occur. I would avoid using perdigons in slower sections of rivers where fish can have a better look and spit out the fly faster than the some of the best angler can detect the take. Tungsten beads are not a regular item on the trouts diet and are quickly ejected. For less turbulent water, choose a fly with some softer materials for the body or collar.

My Top Winter Patterns (updated)

Glenwood Springs Winter Morning

If you are fortunate enough to have a local river that has an endless season, and possess the mental fortitude to suffer through numb fingers and frozen toes, then winter fly fishing season is a great opportunity to fill your fishing logs with additional entries.

Fish and thier prey are still active throughout the winter months -- albeit with slower metabolic rates --  allowing for additional fly fishing opportunities. Only during the coldest spells of deep winter can conditions truly get bad out there leaving the most attractive option to stay home to restock fly boxes. What I find amazing is that when the mercury drops into the teens and below, a few die hard individuals will gleefully brave the elements to chase fin with a fly rod.

The following selection of fly patterns are frequently added to my winter fly box that have served me well throughout a variety of winter fly fishing conditions. 

Cased Caddis

While midges, aquatic worms and baetis dominate the buffet line when sustaining fish through the long dark winter months, cased caddis are a frequent food source. Caddis larva will engage in behavioral drift in search of fresh food supplies or to redistribute the population for better genetic diversity. This behavior makes them vulnerable to easy predation. I often find cased caddis in gastric samples beginning in the late fall and throughout the winter months. 

I often employ a heavy tungsten bead jig as an anchor fly in a multiple fly rig in tandem with an aquatic worm or midge larva imitation. Pictured left is a simple cased grannom with a trailer hitch for adding a dropper behind the fly. What better way to get down deep than with a cased caddis pattern that will both serve to look like a typical stream resident and a likely food source?

Update: I often have mallards and other dabblers feeding in the shallow riffles above the pools that I like to fish. The dabblers feed on cased caddis and often knock them loose in the drift. if I have feeding ducks upstream of me I will use a cased caddis imitation.

Aquatic Worms and Larva

BigPinkWorm.jpg

The Big Pink Worm

I learned to love the Big Pink while winter steelheading in the Pacific Northwest. I used to tie up six inch long rabbit strip versions of this to swing in front of winter steelhead. My largest, a 20 pound steelhead was taken with a pink MOAL articulated pattern. 

For trout's sake, we don't have to anger them by intruding thier personal space with a massive swimming Mother of All Leeches dressed in pink. Instead, a reasonablly sized pink tungsten beaded version does nicely.

Hook: Firehole Sticks 316 #8-16.
Thread: pink.
Bead: Pink Tungsten.
Rear Collar: Pink frosty dub.
Body: Pink micro chenille.

OSS (Oh So Simple) Blood Worm

Blood Worms are found in the sand/silt margins of all bodies of water. After a freshet, sand/silt pockets become perturbed and blood worms can end up in the drift. This is a great fly to have on hand to use after a pulse disturbance in the flow regime. You may want to try one of these if you are fishing downstream of another sloppy angler. Think San Juan shuffle?

Hook: Firehole Sticks 321 #8-16.
Thread: Red 14/0.
Body: Small blood red D-rib, wind forward leaving a distinct gap between wraps. Mark the thread with a gray marker at the thorax area before winding thread forward.

Midges Midges and even more midges

One can never have enough midges in thier fly box, nor have enough variety of patterns. Midge patterns are like the little jewels of a fly box with beads, wires and a variety of colorful tinsels all adorning the smallest hooks. Aside from tying such small patterns, I love the creative license when tying attractive midge patterns.

#1 Holographic Warrior

A spin off of Lance Egan's rainbow warrior which is a spin off of the Lightning Bug which is a spin off of...

Hook: Firehole Sticks 316 #18.
Bead: Silver tungsten.
Tail: Dyed red hackle fibers.
Body: Veevus holographic rainbow tinsel.
Rib: Small silver wire
Thorax: 16/0 Veevus red thread.
Note: By far my most productive fly over the last two winter seasons.

Gun Metal Shop Vac

Hook: Firehole Sticks 316 #18.
Bead: Killer Caddis gun metal glass bead.
Body: Dyed adams gray pheasant tail (Nature's Spirit).
Rib: SemperFli .1mm ice blue wire.
Wing: Hemingway's white frosty dubbing, clipped short.
Thorax: Black hares mask.

The Gun Metal Shop Vac is a cross-over pattern that does well at imitating both midge pupa and baetis emergers.

D'Bling Midge

Hook: Midge hook #18, 24.
Body: D-rib, Olive green, black, tan or gray.
Flash: Small Pearl mylar tinsel, coated with UV resin.

Super simple and most effective.

Zebra Blood Midge

Though frequently referred to as a bloodworm for its worm like larva, the zebra blood midge is actually a chironomid, or a true midge fly. These active 1/4-1/2" or larger larvae are found in almost all water types all year long, but winter finds them more abundant than other available foods. Blood worms prefer soft sandy or silty substrates often found near back eddies or along stream margins to colonize. After a freshet, blood worms are often dislodged from these soft areas and sent adrift making them available for trout. 

Hook: Firehole Sticks 316 #14-18.
Bead: Iridescent Silver glass bead. silver tungsten for heavier patterns.
Body: Red thread.
Rib: Small silver wire.

 Ble Mercury

Ble Mercury

Blue Mercury

The color purple and blue perform wonders in the winter because the low angle of the sun allows the blue wavelengths of light to dominate. This allows the cooler spectrum of colors to radiate nicely, especially when sunk deep into a trout filled pool.

Hook: Firehole Sticks 316 #16-18.
Bead: Iridescent silver glass.
Body: Blue and silver small uni-wire.
Thorax: Teal blue Veevus holographic tinsel.
 

 Opal Midge

Opal Midge

Opal Midge

Hook: Firehole Sticks 316 #16-18
Bead: Iridescent silver glass
Body: Opal tinsel
Collar: Peacock herl
I found this pattern floating around on the internet and gave it a try. It has a lot of qualities that I look for in a fly pattern: simplicity, flash and iridescent qualities.

 
 

Barking at the Moon

moon activity.jpg

Today was one of those days I was skunked. It doesn’t happen all that frequently, but when it does happen, it stings. It had already been a rough week with several lackluster guiding trips in the books. Luckily, the guests that I took out this week were new to fly fishing so just catching their first fish was the goal of the day. It wasn’t easy for one particular guest who fished all day, working every inch of every productive run to catch her fish. Reports from other guides indicated I was not alone in having a difficult time.

As a skilled angler, I have an extensive portfolio of tactics from which to choose when the fishing gets difficult. For me, the most important skill is to know why fishing might be difficult and then how overcome it. In the spring, the challenge might be high dirty water with the tactic being heavier flies to get deep or searching for fish along the margins of the river where fish seek rest from the nagging current. In the late summer when water is low and clear, it might mean fishing smaller, less flashy patterns with lighter tippet. Winter may require small midges, egg and worm patterns.

This week has been an enigma to me, as I had no idea why the fishing was so difficult. I simply could not recognize the cause for my failure. I tried large searching patterns in the deep slots, small dark patterns on the edges and shiny emergers in the film. I tried the finest tippet I could use on the longest leaders that I have. I eventually started blaming the full harvest moon shining a bright light on the water allowing fish to feed at night and rest during the day as cause for the difficult week on the river. I am not one to dive into folklore, legends and myths, so I remain keen to dismiss lunar phases having an effect on fishing, as easily as I dismiss the notion that being a capricorn makes me an asshole solely based on the location where Jupiter and Saturn were located on the day I was born. 

Today, I am blaming the full harvest moon because I have also experienced dismal fishing on other days immediately following the light of a full moon keeping the river illuminated all night long. I have stayed awake late at night to watch blizzards of caddis or aquatic moths emerging and fish feeding in the lunar glow, only to catch nothing the following day. Is it possible to have good fishing during a full moon when the night sky is darkened by overcast conditions? In other natural systems, many species of fish and amphibians time thier mating cycles with specific lunar periods. Is it likely that the moon can affect fish beyond illuminating the night sky? The scientist in me is beginning to wonder. I’m now interested in overlaying the lunar cycles on top of my catch data charts to see if the peaks and valleys in my data can correlate to lunar cycles, including moonrise and moonset. Maybe the fishing will be better tomorrow as the moon wanes?

Addendum: I added a chart with full moons overlaid on top of catch data and see no relationship between full moon and effect on fishing success.

 My current season catch data with full moons indicated with dates.

Catch Statistics Comparing Two Seasons and Hook Changes.

I am a certified data geek. I log every fish that I catch and how I caught them. I can learn a lot about my sport by paying attention to data trends when I analyze the numbers in my log.

This year I switched out all of my hooks from TMC hooks to new tactical hooks such as Firehole Stix, Hanak and Moonlit. I was tired of losing so many fish on hooks that I had to pinch the barb or hooks that straightened out when I tightened the screws on a big fish.

I compared my 2015 season in which I used TMC hooks exclusively to my 2017 in which I am using tactical hooks exclusively. My 2016 season had a mixed bag of hooks with some tactical and some traditional so I discarded that data in this comparison.

I am not making any conclusions or inferences between these two charts that compare the two season. Instead, I will allow you to draw your own conclusions. Needless to say, I feel that things have improved for the percentage of losses.

A loss is defined by having a fish on the end of the line for at least three to five seconds. 

Summary2015.png
summary20172.png

As you can see in 2017 I have fewer private fishing days than in 2015 but caught more fish. What's remarkable is that I went from losing 33.1% of fish to 12.59% of fish in 2017. As in data science, there can be many variables at play including tactics used, but I will leave that discussion alone. Let's just say I love the new range of tactical hooks now readily available on the U.S. market.
