Recent Update: February 2, 2018

 

Even with a shift in to a slightly more typical winter weather pattern, fishing remains decent in most of the places where it has been so far this season.  Overall the weather continues to be favorable for getting out on the water, it’s just that about once a week we are now seeing a storm blow through and drop the temperatures along with a layer of snow.  It usually takes a day or two for temperatures to recover and then it’s back to what has been a very comfortable winter to be on the river.

We are also starting to see a slight, mind you a very slight, improvement to access along some freestone.  This week we have seen a little bit of additional open water along parts of the Eagle and Colorado, which may be just the start if we don’t see a major turn in the overall weather patterns for the late winter/early spring.

As well, the best looking freestone option this winter continues to be the Arkansas, as a drive from the headwaters down to Salida this week illustrated.  Although water releases from Twin Lakes were cut in an effort to conserve what is currently being stored as we continue through this dry spell, the lower flows haven’t caused any additional ice to form.  There will be spots of limited access but, overall conditions allow for plenty of wade fishing.  The lower in the drainage you go, the milder the weather (and better your chances) will be.

Here’s what to expect for open water from Leadville down to Salida.  Hayden Meadows/Kobe are pretty well choked with ice and a very low percentage opportunity.  However, just downstream from there will be the confluence with Lake Creek as it comes out of the tailwater of Twin Lakes.  From there down to Granite is wide open and at a great level for wading.  Although, keep in mind that it is still just about 10,000 feet and on the chilly side.

Below Granite there will stretches with minimal sunlight where ice returns to the river, offering inconsistent access down to Buena Vista.  But once in BV, the open valley combined with warm water discharges from their treatment facilities, opens the river up all the way down to the top of Brown’s Canyon.  Brown’s will shade the river and may add a bit of ice through that stretch before the river opens back up above Salida at the Stone Bridge access.  Even so, we have had some good winter action in Brown’s Canyon over the past few weeks.  From Stone Bridge down through Salida to the start of Big Horn Sheep Canyon, the river is open from bank-to-bank.  Check the Arkansas location reports below for specific details.

While the freestone options may be diminishing, there are still the tried and true winter standards – tailwaters.  The Blue, Frying Pan, Cheeseman, 11 Mile, Pueblo.  Whichever works for you, there are just enough options to feed your habit for the near future.  Some guys love this time of year and those options, while the rest of us simply tolerate it.  If you are in the latter, the bright side is we have passed the winter solstice and the days are steadily getting longer from here on out.

 

General Tips for Winter Fishing:

Even though it has been a relatively mild winter and , the calendar doesn’t lie when it comes to daylight hours.  That being the case, you will want to focus your efforts on the late morning through mid-afternoon for the greatest success, 11 am to 3 pm on most rivers has been the most productive time frame.  Look for water that offers some cover from the heaviest currents as well as from predators under these late season conditions of low and very clear water; ledges, runs and pools seem to be the best place to start.

As well, with overnight temperatures at times now dropping into the teens, if not single digits, you might need to adjust your freestone approach for these remaining days of open water.  It will be quite possible that when you arrive at the river early in the day, there will be some level of ice flow drifting through.  If that is the case, don’t panic, it could be a short-lived event.  Be patient and give it a chance to warm up and see if the ice clears off.  This may not happen until late in the morning depending on your location.  Better idea altogether would be to slow- play your morning and don’t arrive at the river until late morning, thus offering a better chance at open water.

Generally speaking it will be Midges on most rivers, with a few remaining Baetis scattered around. Detail reports below will give more specific information on a particular stretch of river. Make sure to check those out for your river of interest, as they will be able to answer questions pertaining to hatches and flies.

 

Blue River Below Dillon Reservoir

Flow: 95 cfs
Conditions:  Stream flows remain slightly above typical seasonal levels, which is good news as more water can mean more food in the river. Action has been decent but, the river seems to be feeling the pressure of the sub-par ski conditions and the increase in anglers that has brought, with the most consistent results coming on subsurface patterns for Mysis, Midges and some Baetis emergers – specifically RS-2s.  As well, the usual tailwater staples of Eggs, San Juans and small searching patterns have been finding some fish.  With the flows hovering near their seasonal lows, we would also drop our tippet back to at least 6x.  However, we wouldn’t necessarily recommend cutting your weight down as a general rule. There are still plenty of runs that benefit from using heavier weight that you would think.  As the saying goes, most often the thing that separates a nymph fisherman from a successful nymph fisherman is the amount of weight used in their set-up.  Experiment with your weight throughout the day and make sure that you are getting down to the depth you need quickly, that is the key to more fish seeing your offerings.  If you aren’t bumping the bottom on occasion, chances are you need more weight.  For those dry fly enthusiasts out there, we have been seeing scattered fish feeding on the surface at times.  Keep your eyes peeled, as it will not be widespread.  If you do find fish on the surface they have been taking emerging Midges in Black, Chocolate and Dun colors, sized #22-26.  Good luck with that.

 

Town Flies: BTS Shrimp, Tim’s Mysis, Stalcup’s Mysis, Andrew’s 5-0 Midge, Red Neck Midge, Glassy Brassie, Mirage Zebra Midge, Desert Storm, Rainbow Warrior, Black Beauty, Brassie, UV Emerger, Biot Midge, Lil Spanker, Tungsten Psycho May-Black, Rojo Midge, Tube Midge – Black or Red, RS-2 – Black or Dun, WD40 – Black or Chocolate, Zebra Midge, Otter Soft Milking Egg, Bead Eggs, Flossy Worm, Gummy Worm, Sparkle Worm, And work in a streamer every once in a while, as well. Often over looked but, randomly deadly.


Blue River Below Green Mountain

Flow: 200 +/- cfs
Conditions:  Flows have settled in to their winter lows allowing for much greater access, as you can now cross the river relatively safely and double the amount of water available for fishing.  Overall fishing has been very good and as a bonus, the frigid temperatures typical of the canyon in the winter have been almost nonexistent.  Results will be best on tandem nymph rigs, with a wide assortment of patterns.  At this time of year you will want to emphasize the Midge and Baetis imitations but, there continues to be action on Stonefly imitations, Eggs and mid-sized searching patterns fished as the point fly in those tandem rigs.  We continue to find a little better action in the deeper runs, just outside the seams and towards the tail-outs, where flows are less intense.  Cloudy days have been slightly more consistent for action, as the low and clear flows tend to magnify your shadows and movements on sunny days.  As well, those overcast days have produced a little interest in surface feeding to emerging midges along with some minor streamer activity.  Even though flows are at seasonal lows, don’t underestimate the amount of weight needed to get your flies down to fish holding on the bottom of deep runs.  As well, 5x mono should be adequate enough for the clarity, with 5x fluorocarbon offering a little more stealth for the conditions.  If you aren’t familiar with this piece of river in the winter, be prepared for the steep access from the parking area down to the river.  Just a little bit of snow or moisture on the slope can make for a treacherous descent or climb back out at the end of the day.

Sculpzilla, Sex Dungeon, Cheech Leech, Sparkle Minnow etc


Colorado River Above Kremmling (Parshall)

Flow: 220 +/- cfs
Conditions:  Flows are getting down to winter lows as the Williams Fork is only adding about 40 cfs to the native flow in the river.  However, the river is providing open, fish-able water down a ways into the Breeze Unit, at least a run or two below the bridge.  Action has been pretty solid for what is considered the dead of winter, with the majority of that action coming on nymph imitations fished in tandem nymph rigs.  Interest has been best on a mix of small midge pupa and larva imitations, and Baetis patterns.  We are also finding success on small to medium sized Stonefly and searching nymphs used as the lead flies in those set-ups.  With the low and clear conditions, tippet in 5 to 6x has been most productive in both mono and fluoro.  Don’t overlook the factor that weight plays into the equation either.  Even with the low flow there is a need for your flies to get down expeditiously in the compact and deep winter lies that fish are favoring right now.  Look for runs and pools that offer a little bit of depth that can provide cover from predators in these clear water conditions, preferably with a decent bit of current at the top end of them to bring in both food and oxygen.  Likewise, avoid the slow and shallow flat water that will leave them exposed.  And now that overnight temps have hit single digit to sub-zero levels there isn’t going to be much opportunity above the Willie’s, as ice has set in.  Concentrate your efforts below that influx of tailwater stability.

 

Flies: Pat’s Rubber Legs, Flossy Worm, CDC Pheasant Tail, Bead Prince, Psycho Prince, Hammerhead Nymph, Lil Spanker, Tungsten Hackled, Pheasant Tail #18-22, Black Copper John #20-22, Tung Psycho May, Split Case BWO, Tungsten Micro Mayfly Brown, Tungsten Juju Baetis, Aero Baetis, Root Beer Float, Zebra Midge, RS-2, Foam Wing RS-2, Red Neck Midge, BH Biot Midge, 5-0 Midge, WD40, Pure Midge Larva, Chocolate Thunder


Colorado River Pumphouse to Dotsero

Flow: 440 +/- cfs. @ Pumphouse
Conditions:  Winter conditions continue to be prevalent along this popular stretch of river as low overnight temperatures counter the warmer than average daytime temps.  However, as the temperatures continue to be erratic, there has been little to any consistency on those conditions.  Although it might still be day-to-day in a few locations, the majority of the river is heavily iced.  That varies from full coverage in some spots to narrow open channels in other areas.  And any of those open spots have a good chance of seeing flow ice for large portions of the day.  This isn’t to say that you can’t still find a spot of open water, free of drifting ice at some point in the next couple of weeks but, with the cold overnight temperatures and the shortest days of the year, don’t put all of your eggs in this basket when searching out a location to hit.  But if you happen to be in the neighborhood and you find some open water, then here’s how to approach your day.  As is the case everywhere right now, subsurface patterns fished in a traditional tandem nymph rig will offer the most consistent results.  Anchor your set-up with a Stonefly, Egg or mid-sized searching pattern and follow that up with a Midge or Baetis imitation.  4 and 5x tippet are adequate with the current flow and clarity and make sure to use enough weight to come in contact with the bottom on occasion, just often enough to know that you are getting it down where trout are holding as they conserve energy at this time of year. Look for fish to be holding toward the center of the river in slightly deeper runs, flats and glides.  With the low light and shorter days, daytime temperatures are slow to climb in the morning.  As such, we have found the wider valley areas, that are prone to greater sun exposure to be more productive through the afternoon hours.  Conversely, we have been finding little to no success in any of the canyon stretches (not to mention they are locked up in ice at the moment).  Suffice it to say the river is wade only in most places at he moment.

 

Flies: Pat’s Rubber Legs, Psycho Prince, Yeager’s Soft Hackle, Bead Head Pheasant Tail, Duracell, Lil Spanker, Mirage Zebra Midge, Foam Wing RS-2, Poison Tung, BH Biot Midge, Tungsten Psycho May, Darth Baetis, Eggs, San Juan Worm, Sculpzilla, Silver Bullet, Sex Dungeon, Cheech Leech, Crystal Bugger


Colorado Below Glenwood Springs

Flow: 1300 cfs
Conditions:  Conditions on the lower river remain manageable and the action continues to be solid, as well.  Although now that temperatures have fallen to more seasonal lows, you can expect to encounter flow ice at times.  While the best results have been on deep, tandem nymph rigs, there are still some fish being taken on streamers.  With those nymph set-ups, lead with a medium to large beaded searching nymph, Stonefly imitation or Egg pattern and follow that up with a Baetis or Midge of your choice.  Clarity for this part of the river is in great shape but, you can still be stealthy enough with 4x tippet, even 3x if you would prefer a little more holding power when you hook up.  Look for deep cover, ledges and drops to be holding fish most consistently.  This stretch of the river is entirely different than anything upstream from Dotsero but, if you can get past it’s proximity to the highway it is definitely worth the trip.  Although floating it does offer the best access for the patchwork of public water that can be hard to reach on foot, there are plenty of spots to drive/walk in to.  Don’t let the size of the river intimidate you, rather break it down into smaller pieces and fish it like you would any other wade river you are familiar with.  This stretch consistently produces some of the nicest Rainbows on the Colorado River and late fall through early spring is a great time to get out and explore this overlooked location.

 

Flies: Pat’s Rubber Legs, Tungteaser, CDC BH Pheasant Tail, Bead Prince, Duracell Jig, Tungsten Pheasant Tail, Bead Hares Ear, San Juan Worm patterns, Lil Spanker, Tung Psycho May, Big Spanker, Rainbow Warrior, Magic Fly, RS-2, Bead Eggs, Otter Egg, Flossy Worm


 

Arkansas River Above Buena Vista

Flow: 105+/- cfs @ Granite & Ice is forming @Hayden Meadows
Conditions:  Still fairly cold along the upper part of the river, and the popular public water stretch through Hayden Meadows has mostly iced over.  However, a slight release out of Twin Lakes continues to keep the river wide open from Balltown down through Granite and beyond. Definitely focus your efforts on this stretch from Balltown to Granite.  Nymphing will offer the best approach with 4 and 5x tippet in a two fly set-up.  Lead with a mid-sized to small beaded Stonefly or searching pattern and follow that up with a Midge pupa or larva.  Look for fish to be congregating in winter water that offers a little more shelter from the heavy currents, such as deeper runs, tail outs to pools and ledges.  Probably not the hottest destination for this time of year but, there is potential for some action.  If nothing else you shouldn’t see much in the way of competition.

 

Flies: Pat’s Rubber Legs, Red Collar Leggy PT, Duracell, Copper John, BH Pheasant Tail, BH Hare’s Ear, Lil Spanker, Hot Wire Prince, Psycho Prince, Yeager’s Soft Hackle J, Iron Sally, Hammerhead Jig, Mirage Zebra, Red Neck Midge, Poison Tung, BH Biot Midge, Flossy Worm, Silver Bullet, Sparkle Minnow.


Arkansas River Salida Area

Flow: 280 +/- cfs @ Salida
Conditions:  Flows are back down to seasonal norms now that the water call has ended.  However, the warmer than seasonal temps have kept the river free of ice in many popular locations, specifically in the valley area from Stone Bridge down through Salida.  As the water has dropped fish in some areas will have moved out to deeper parts of the river as their cover along the edges may have disappeared.  Look for fish out slightly from the edges along the drops just off the current lines.  Runs with a little depth and pools that offer cover without a lot of energy consumption have been consistent, as well.  Early in the day fish will be sluggish to start but, that should change mid-day as they feed on Midge pupa and larva.  As the day goes on there may also be some interest in Baetis nymphs behind a mid-sized searching pattern such as BH Pheasant Tail, Duracell Jig or your go to fly for that category.  We continue to have good success on Stonefly, Midge, Baetis and Beaded searching patterns all throughout the afternoon.  With clarity as good as it is, 5x is ideal but, the extra flow in the river might allow for 4x to your top fly.  This is a great destination right now as there is far less traffic than on some of the other open water spots at the moment.  Not to mention the weather is generally noticeably warmer down this way.  On a mid-week day this week, we had the place to ourselves and enjoyed steady action.  Probably the best freestone destination in the state at the moment.  And it is just about time for the Stoneflies to start their molting process.  Typically starting around mid-February, the Golden Stoneflies will molt (the process of shedding their exoskeleton) which will make their overall appearance brighter and more noticeable.  As well, during this process they will be at greater risk for being dislodged from the bottom of the river and drifting in the water column, readily available for trout to feed on.  This really kicks off the early spring action as fish that have conserved calories all winter look to bulk up in advance of spring snow melt.

 

Flies: Beadhead Pheasant Tail, Red Collar Leggy PT, Beadhead Prince, Beadhead Hare’s Ear, Red or Chartreuse Copper John, Hot Wire Prince, Iron Sallie, Psycho Prince, Hammerhead, Duracell Jig, Barr’s Emerger, Juju Baetis, Tungsten Psycho May BWO, Yeager’s Soft Hackle, Extended Body Para BWO, Zebra Midge, Poison Tung, Rainbow Warrior, BH Biot Midge, Brassie, Lil Spanker, Big Spanker, Mirage Midge, Red Neck Midge, Biot Pupa Midge, Tan Pat’s Rubber, Tungsten Yellow Sallie, Masked Marauder


Roaring Fork River at Glenwood Springs

Flow: 390 cfs
Conditions:  A good option at this time of year as warm weather and solid flows are keeping insect activity high enough to spur good action through the middle part of the day.  The lower reaches of the river offer the better weather and water temps and the consistency of feeding is following that trend but, there remain decent moments in the Carbondale to Basalt stretch as well.  With the colder temps the last week or two, expect to find flow ice in the river early in the day, which may not clear until early afternoon.  Deep nymph rigs have been the best approach with 4 and 5x tippet.  Start with a BH searching pattern, Stonefly imitation or Egg on top, dropping down to a Baetis or Midge imitation, using a good amount of weight.  Even though the flow is low, most of the fish will be holding in deeper buckets and runs that require some weight to get down quickly.  Also of note, the lower river had not gotten much float traffic from August to November due to the bridge closure that had serious impacts on traffic in the valley.  The new bridge is finally open, once again offering easy access to Glenwood.  Those fish in that stretch seemed to be a little less sensitive than a normal year as a result to the interruption in floaters.  Check that out before they readjust to more typical attention.

 

Flies: Midge Emergers, UV Emerger, Glassy Brassie, Beadhead Biot Midge, Poison Tung, Beaded Pheasant Tail, Pat’s Rubber Legs #8-10, Psycho Prince, CDC Prince, Hot Wire Prince, Standard Pheasant Tail, Tung Psycho May, Split Case BWO, RS2, Frenchie, Lil Spanker, Big Spanker, Duracell Jig, Root Beer Float, Foam Wing RS2, Yeager’s Soft Hackle,


South Platte River, Middle Fork

Flow: 30 +/- cfs
Conditions:  Winter. Ice. Limited opportunity.

 

Flies: Beaded Prince, Duracell Jig, Hammerhead Jig, Red Collar PT, Beaded Pheasant Tail, Big Spanker, Zebra Midge, Mirage Midge, Red Neck Midge


South Platte, Dream Stream

Flow: 77 cfs
Conditions:   Flows have settled in under a hundred, which is a typical winter level but, also a flow that will fish a little better if you think about your approach the river.  Make sure to travel with a little greater caution when moving along and in the river.  Slow down and make sure your foot steps are light, so as to not alert fish to your presence.  Minimize wading and keep a lower profile.  Once at a spot where you intend to fish, don’t be in a hurry there either.  Slow, calm movements with your rod and cast, limit your extraneous movements.  Light tippets of 6x will offer the best presentation.  Midge pupa, larva and emergers will be the core of trout diets through the winter but, there will still be some action on small Baetis imitations.

 

Flies: Loop Wing Emerger, Pure Midge Larva Black or Pale Olive, Black, Red, Chartreuse Copper John, Juju Baetis, Caddis Larva, Poxybiot Nymph, Desert Storm Chartreuse, Tube Midge, Poison Tung, Zebra Midge Black/Silver, Barr’s Emerger BWO, RS2, Poxybiot Nymph, Egg Patterns, Cap’n Hook, Disco Midge, San Juan Worm variations, Crane Fly Larva, Buckskin, Bread Crust


Williams Fork River Below Dam

Flow: 40 cfs
Conditions:  Dam releases are down to winter levels and may drop further.  As it gets down to these sub 75 levels, the action really tightens up on this popular tailwater, which gets more than it’s fair share of traffic.  As such, drop your tippets to 6x, even 7 if you are comfortable with that light of line.  Midge pupa, larva and emergers along with Baetis patterns will be most productive.  These can be fished together or behind a small searching pattern, such as a size 20 Flashback Pheasant Tail, or Caddis larva.  Look for fish to be “holed up” in the few deeper spots that are available at this low flow.  Now that the temperatures have adjusted to more seasonal levels, add an extra layer because it gets cold in this valley.

 

Flies: Split Case BWO, Poxy-Biot Nymph, Buckskin, Flossy Worm, Little Brown Bug, Two Bit Hooker, Flash Back Pheasant Tail, Tungsten Micro Mayfly, Big Bear Baetis, Tungsten Psycho May BWO, Pure Midge Larva, Rainbow Warrior, Rojo Midge, Biot mayfly Emerger, #20-22 Green Copper John, Zebra Midge, RS2’s, 5-0 Midge, UV Emerger


Eagle River

Flow: 95 @ Wolcott 160+/- cfs @ Gypsum
Conditions:  Ice has finally settled for large portions of the valley.  There are still open water options and the fishing at those locations remains pretty decent considering the time of year.  Best options are going to be lower in the valley, generally near Gypsum but, there will be pockets upstream all the way to Avon if you are close enough to the few warm water discharges that keep the river open.  Even where you do find that open water, don’t be surprised to find ice flow early in the day.  That should clear by mid-day and offer decent conditions through the afternoon.  Results have been best with a two nymph set-up, rigged with 5 and 6x tippet.  Lead with an Egg or mid-sized searching nymph and follow that up with a Midge or Baetis pattern.  Look for runs that have a bit of a current formed by a drop at the head of the pool.  With the less than stellar conditions on the ski hill so far this season, there has been a noticeable amount of traffic along this river.  At times it has been busier than the summer.  That is due to the limited amount of open water at the moment but, the point is to be prepared to encounter other anglers if you are headed this way.
