 The Blue River in Silverthorne fly fishing report has been that trout like this rainbow trout are plentiful but hard to catch. Rainbows are the primary targets of anglers fly fishing the Blue River in Colorado


The dry fly action on the Blue River in Silverthorne has dropped off a bit lately. The nymph fishing has been good with a hopper/dropper rig or under a small, neutral colored indicator. Flies that are working include: size 20-22 black or red Pure Midges, size 20-22 natural Pheasant Tails, size 20-22 red Tailwater Tiny's, size 20-22 cream or brown Bling Midges, size 20-22 Juju Zebra Midges, size 20-22 Parachute Adams and size 20-22 Extended Body Blue Wing Olives.


Mysis Shrimp are still on the menu, especially in the morning and the evening. But flies imitating tiny midges and small mayflies have generally been more productive.


We are seeing occasional, light intensity Blue Wing Olive hatches in town on some of the gray, rainy days. Midges are also hatching some afternoons. If you travel down river 15 miles or so, you will likely run into better Blue Wing Olive activity.


Unless it is cloudy, we haven't seen many fish feeding on the surface during the day. Most of the action has been subsurface. That said, you can sometimes entice a trout or two to eat a size 14-18 Elk Hair Caddis, a size 14 Amy's Ant or a size 14-18 Parachute Adams. As a general rule-of-thumb, the late evenings and the overcast days hold the greatest possibility of finding fish willing to eat on the surface. But don't expect to find "lights-out" dry fly fishing on the Blue River in Silverthorne on a consistent basis.


We suggest using the smallest, neutral colored indicator that you can still see. Brightly colored indicators often alert the trout of your presence and they will either spook or just refuse to eat your fly. White or black yarn indicators, small sized white or "glow-in-the-dark" Thingamabobbers are always good choices when fishing the Blue River in Silverthorne. Fishing without an indicator, although tricky, can be deadly as well.


If you don't use streamers on the Blue River, you should consider doing so. This is especially true during the fall into the early winter. Streamer fishing is, at times, a very effective strategy and is an underused technique by most anglers fishing the Blue River in Silverthorne. Don't be afraid of using the big, articulated patterns available these days. Trailing a black or olive Houdini behind a black or white Dungeon is often a winning strategy. 


Streamers to try: Sex Dungeons, Barely Legals, Home Invaders, Houdini, Thin Mints, Super Buggers and all sizes and colors of the standard "Woolly Bugger."


Question: What's going on with the Gold Medal status of the Blue River?


Answer: The Blue River between Silverthorne and Green Mountain Reservoir has been delisted from Colorado's Gold Medal list. The Blue within the city limits of Silverthorne is still listed as Gold Medal water. There are still great fish to be caught on the Blue north of Silverthorne. If you check in with us regularly, you have seen hundreds of photos of fish that were caught in this stretch over the years. And we try to post current pics regularly. It's true; you won't find the numbers of fish that you will see in Silverthorne. But you will find fewer anglers and less selective fish!

  Fly fishing the Blue River is our fly shop's specialty. Stop on by our Silverthorne location and pick up what you need

The Blue River below Dillon Reservoir is running at 110 cfs today. This flow is a very angler friendly level as the river is accessible bank to bank. We are seeing mostly midge activity and the occasional Blue Wing Olive hatch from Silverthorne to Green Mountain Reservoir. The hatches tend to be strongest as you head north, away from Silverthorne, but you can currently encounter strong, localized hatches on almost any stretch of the Blue. 


Patterns for this stretch:


Nymphs: #16-#18 Tungsten Yellow Sallies, Prince Nymphs: #16-#18, # 18-#22 Standard Pheasant Tails, #16-#18 Bit Hookers, #18-#20 Split-Case BWO Nymphs, #18-#22 Miracle Midges. #18-#22 olive or black WD-40's, and #18-#22 gray or olive RS-2's.


Dries: #16-#22 Parachute Adams, #18-#20 Gulper Specials, and #14-#16 Royal Wulffs.


The action on the Blue River north of Silverthorne is currently fair, with some anglers having success and others not so much. This often has more to do with the fish than it does the angler. The trout in the Blue can be finicky and reluctant to eat even your best presented offerings.


The determined wade angler will find trout spread out in the best feeding lies. Don't expect to find fish stacked up like you will see in Silverthorne. The farther one gets away for Lake Dillon, the more the Blue River fishes like a freestone river. Moreover, you'll need to work a bit harder to successfully fish the Blue north of town; the fish population is smaller in the northern reaches of the river than it is in Silverthorne. The concentration of fish improves, however, in the mile or so above where the Blue River enters Green Mountain Reservoir (i.e. the inlet area). Trout that live north of Silverthorne will often take a variety of fly patterns and are, generally, less selective than the trout residing just below the Lake Dillon Dam. When fishing this stretch, covering more ground often equates to more hook-ups. 5x fluorocarbon tippet is recommended.




Our fly shop has the flies, waders, boots and guides for your day of fly fishing. We are located on the Blue River in Silverthorne, Colorado.


In the late spring, summer and fall, keep in mind that the Blue north of Silverthorne can fish much better on the surface than under it. There's no explaining this phenomenon but after years of guiding this water it has proven to be the case more often than not. Dropping a bead head nymph from a medium to large dry fly is often the best technique when you find traditional nymphing to be unproductive. The inlet area to Green Mountain Reservoir is fishing fair. This is usually a go to location at this time of year. The fact that the inlet isn't "on" right now is most likely due to the fact that Green Mountain Reservoir hasn't been stocked this year in an attempt to rid the Kokanee Salmon in the reservoir of gill lice. There are no plans to stock Green Mountain Reservoir this year at all. Current plans also call for no stocking of Green Mountain Reservoir next year.


FYI: The Blue River between Silverthorne and Green Mountain Reservoir has been delisted from the Gold Medal list. The Blue within the city limits of Silverthorne is still listed as Gold Medal water. There are still great fish to be caught on the Blue north of Silverthorne. If you check in with us regularly, you have seen hundreds of photos of fish that were caught in this stretch over the years.

 We often use 2 flies when fly fishing near Silverthorne, Colorado. Sometimes we catch fish on both flies at the same time


The Colorado near Parshall is seeing some slush on the colder days and nights. The river has very good visibility and is flowing at about 120 cfs above its confluence with the Williams Fork tailwater and 200 cfs below that confluence. While there are still browns in the process of spawning, we are seeing decreasing numbers of fish on their beds. The fishing lately has been poor to fair. The trout are moving (have moved?) into their "winter water." So look to find fish in the deeper, slower pools. 


The fishing has been a day-to-day affair and often very fly specific. Don't be afraid to change flies often if you aren't hooking up and be sure to move up or down the river if you aren't having any success. Sometimes, just traveling a mile can make a huge difference in finding trout with better attitudes.


Midges are the insects of importance right now. Egg patterns are playing a roll as well. The best nymphs have been #20-#24 Miracle Nymphs, #20-#22 foam wing emergers in chocolate, gray and olive, #18-#22 natural Pheasant Tails, #20-#24 black or gray RS-2's or WD-40's, and egg patterns in peach, green or muted orange.


Dry flies have been effective from time to time. Best patterns have been:#20-#24 Morgan Midges, #22 Matthews Sparkle Dun BWO's, and #18-#24 Parachute Adams.


Our guides catch mostly brown trout on our guided trips. The Colorado River is one of the fly fishing best destination rivers in Colorado


Try changing (primarily adding) weight before changing flies. If your flies aren't occasionally ticking the bottom, and you aren't hooking up, add some weight (or heavier flies) until you occasionally get hung up. The opposite, of course, can also be true--it is just less common! If you are constantly cleaning your flies, or hanging up, take off a bit of weight. Our guides have been using 4x-5x fluorocarbon tippet depending on the amount of water clarity on any given day.


Don't forget to try a streamer. Larger patterns often work best as they move a ton of water and create a larger vibration in the water. Trailing a smaller streamer behind the larger streamer can crush fish some days. Common set-ups include: Sex Dungeon (any color) trailing a Wounded Sculpin, Sparkle Minnow trailing a Houdini or a Home Invader (black, white or tan) trailing a Slump Buster (rust, black or olive). 


Here are some thoughts to keep in mind when fishing the upper Colorado River near Parshall: In the winter, the water temperature on the Colorado River below the Williams Fork confluence will generally be warmer than the temperature of the Colorado above the confluence. In summer, the opposite is typically true; the water temp is colder on the Colorado River below the Williams Fork confluence and warmer above the confluence. This difference in water temperature will often trigger different insect hatches. For example, you might find Blue Wing Olives hatching below the Williams Fork confluence but not hatching above the confluence (and vice versa). It is not unusual to find better (or poorer) Fishing on the Colorado River near Parshall simply by moving a few miles upstream or downstream.

Check out our Colorado fly fishing reports to catch rainbow trout like this one. If you don't have the time to read our Colorado fishing reports, stop by our Silverthorne fly shop or book a guided trip


Th river is currently fishable from Pumphouse (and above) down to Dotsero. Fishing has been fair to good depending on the day and the stretch of river you are fishing. We are definitely seeing a slow down in the action as the browns get more serious about spawning. Dry flies have been the way to go some days. But short nymphing under an indicator has been working as well. The streamer action has been disappointing with all of our sunny weather but the action can be decent early in the morning and just before dark. In fact, if the forecast is for Bluebird skies, it would be a good idea to fish early and late no matter what technique you are using.


Expect to find fish throughout the river and, in particular, we are finding feeding fish in the softer, deeper troughs and buckets. We are still finding fish in the shallow, fast riffles but they are not always interested in feeding. Many of the nicer rainbows are setting up in the slightly deeper water below the faster pockets and riffles. The rainbows are definitely interested in feeding but eggs haven't been all that effective lately.


Nymphs that are catching fish include: #8-#10 black or coffee Pat's Rubberlegs, #16-#20 Tungsten CDC Pheasant Tails, #16-#18 red Two-Bit Hookers (or red Copper Johns), #16-#18 CDC Hare's Ears, #16 TDJ Hare's Ears, #18-#20 Tungsten Psycho BWO's, #18-#22 standard Pheasant Tails, and #18-20 Tungsten Split-Cased BWO's. As always, call us (970-262-2878) for the most current report.


Dry flies to use: #14-#16 Chubby Chernobyls in gold or olive, #14-#18 yellow or orange Stimulators, #16-#20 Parachute Adams or Parachute BWO's, #16-#18 Elk Hair Caddis and Grasshopper patterns of all sizes.


The streamer bite has been sporadic to nonexistent but we are hopeful that will change when we begin to see some cooler, cloudier weather move in. The best streamers have been: Sculpzillas in tan or tan/orange, Thin-Mints, Tan and Yellow Baby Gongas, Slump Busters in black or rust, Autumn Splendors and Dungeons in black or rust. You never know for sure what streamer will be magic so come to the party with a good selection of pattens in different sizes and colors. In the late fall, a streamer incorporating orange and/or yellow is something you should never leave home without.


This brown was caught on a guided float trip on the Colorado River near Pumphouse. Stop in our Silverthorne fly shop to get all the flies needed to catch fish in Summit County


Finding the "pattern" to the trout's feeding lies on any given day can make the difference between catching a couple of fish or hooking up many fish. Pay attention to where you are catching fish and look to find similar water elsewhere on the river. If your "pattern" begins to let you down look to change up what you are doing in hopes of finding another "pattern" to the trout's feeding. Here's what most guides do: Change flies, change where in the river they are fishing them and play around with how deep they are fishing them.


 As always, call the shop for the latest info: 970-262-2878.

The fishing is tough on the upper Arkansas. Colder weather and the end of the brown trout spawn are the culprits. We suggest fishing lower on the river (near Salida or below Salida). If that's too far, the following nymphs will get you a fish or two. 


Nymphs to try: Standard or Black Pheasant Tails (#18-#22),  Midge Patterns in red, gray or olive (#18-#22), CDC Tungsten Pheasant Tails (#18-#20) and Sparkle wing RS-2's in Olive or gray (#18-#22).


Dries to try: Parachute Adams (#18-#22) and Sparkle Baetis (#22).

Great rainbow caught on the Arkansas River


The action on the Arkansas River near Salida is slowing down for sure. This is in large part due to the colder water temps, which cause the trout's metabolism to slow. There are still decent hatches of midges most days. So work the slower, deeper pools and be sure to use plenty of weight if you aren't hooking up. Also, since the fish are generally locating in the slower sections of the river, they get a better look at your fly. So downsize your tippet and think about using bead-less flies.


Best nymphs have been: #22 red or black Rojo Midges, #20-#22 black Pure Midges, #18-#22 Black Beauties and egg patterns in apricot or light orange.

Guided float trips are a great way to fly fish any river. The Roaring Fork River is one of our favorite rivers to fly fish from a boat


The Roaring Fork River is fishing fair. The river is still floatable at 520 cfs but it is very bony, especially for a hard boat. 


Most days, nymphing has been better than either dry flies or streamers but the streamer has its days (or periods throughout the day). The Blue Wing Olive hatch is over so think Midge patterns, eggs and, maybe, streamers.


Although the dry fly fishing can be non-existent some days, this is the time of year that you should be on the look-out for pods of rising fish. Don't overlook these pods, especially if you are floating. Stopping to fish these podded up fish is often your best chance of putting up good numbers for the day.


The fish are getting more selective so drop your fluorocarbon tippet down to 4x or 5x, and consider using a dry fly for your indicator instead of a Thingamabobber. You might even have to lose the bead on your smaller nymphs.

Come to Silverthorne, Colorado and fly fish for trophy trout like this one. We guide on many rivers located only a short drive from our Summit County fly shop.Midges are the insects of most importance. Egg patterns and streamers have been catching good numbers of trout as well. Some big trout are still in the system but many of the big fish have returned to Elevenmile Reservoir.

Night fishing has produced the biggest trout lately. There are still a few Kokanee Salmon in the river as well. Fishing has been fair to very good depending on the day........and the wind.

Last thought: Streamers and eggs seem to be most effective early and late in the day.

A Williams Fork River brown trout


The flow has been steady at 75 CFS for a while now. There are good numbers of browns in the river at this time. The brown trout spawn is pretty much over but please be respectful and avoid fishing to any remaining pairs of fish and to any fish actively working on their spawning beds. You need to be careful where you walk so as to not walk on the areas of clean gravel. These clean spots are where the brown eggs are deposited and walking on these "redds" literally kills the the trout we will have to fish in the years to come.


Best flies have been Pheasant Tails, gray or olive RS-2's, #20 Miracle Midges,and midges in black or olive. Keep your hook sizes between 18 and 22. Fishing isn't off the hook but it is worth the mile (fish) walk into the river from the parking lot. The streamer action is fair, as is the action on egg patterns.

There is no commercial guiding (wade or float) allowed on this stretch of the Blue but most of the shop guys love to fish it when they get a chance. The current flow of 250 cfs is a very good level for wade fishing but not high enough for float fishing. The latest guidance from the Bureau of Reclamation is that "flows in the Blue River will fluctuate between 200 and 250 cfs for the foreseeable future." 


There is no commercial guiding allowed on the Blue River below Green Mountain Reservoir. But stop into our Silverthorne fly shop to pick up flies that work


The nymph fishing in the public stretch just below Green Mountain Dam has been good to very good now that the water has dropped to a level suitable for wade fishing. The best nymphs have been: #18 Tungsten Yellow Sallies, #16-#18 Hare's Ears, #20 Juju Emergers, #14-#16 TDJ Golden Stones, #20-#22 black Pure Midges, and #18-#24 natural Pheasant Tails.


Best Dries have been: #22-24 Winger Emerger Baetis, #20-#26 Parachute Adams, #22 Matthew's Sparkle Dun, #22 Extended Body BWO's.


Streamers are a good option right now on the Blue River below Green Mountain Reservoir. We love using large, articulated streamers but don't forget to try the more traditional, smaller streamers. You might be surprised how well the "oldies" produce!


Please remember that wade fishing is only allowed in the public stretches of the Blue River below Green Mountain Reservoir. This primarily consists of the approximately 1.5 miles or so of river bank located just below the reservoir. The public water ends at the private land/no trespassing postings. Float fishing is allowed below the reservoir but wade fishing on private property is trespassing, as is anchoring a boat on private land. For those of you that are new to Colorado's stream laws, the landowner does not own the water passing through private land but the landowner does own the stream bottom. Colorado's stream laws are not the same as the stream laws in Montana (Montana law allows an angler to stand on private property up to the "High-Water" mark).


Please keep in mind that Mountain Lions call this area home throughout the year. Please consider leaving your dog at home and keep a watchful eye when hiking/fishing.
