 Fly fishing in Silverthorne, Colorado on the Blue River. The Blue River flows through Silverthorne and immediately behind Cutthroat Anglers


The Blue below Dillon Reservoir is currently running at 113 cfs. This is an excellent flow for fishing the Blue River. The fish have spread themselves out now that the high water is no longer pinning them to the bank and willows. The river can rate as high as a 4 if you catch the hatch right, or if you catch the fish in the right mood. Dry flies are definitely a great option right now, but as usual, you will catch more fish if you nymph, especially before and after the hatches that are occurring. While definitely winding down, we are still seeing a few Caddis and small Yellow Sallies most days. Midges are hatching almost every day and we are still seeing a mayfly spinner falls in the late morning and early evenings. 


The water temperatures behind the shop are beginning to slowly fall. Expect this trend to continue as the reservoir cools and the "fill and spill" we enjoyed this summer comes to an end.


The reality for fly selection on the Blue River in Silverthorne is that not much changes. The fish in the Blue River in town tend to like small flies fished under the water's surface. Yes, you will find fish willing to eat larger flies in the middle of summer but they will almost always be just as happy to eat small midge imitations and Mysis shrimp. It should come as no surprise then that red or black Midge in sizes #18-#26 have been very productive as of late. Mysis imitations in sizes 18-22 are also fooling fish and are often most effective early and late in the day. #16-#20 Caddis Larvae and Golden Stone nymph imitations are still receiving some attention but have less productive as of late than they were a few weeks ago. Pink or brown Gummy Worms are also a great choice when fishing the Blue in Silverthorne, especially in low light and/or stained water conditions.


Dry flies are still an option. #16-#18 Parachute Adams, #14-#18 Elk Hair Caddis, and #12-#18 yellow or royal Stimulators are getting the job done on the surface. For those of you dedicated to catching fish on the surface, don't expect to target only rising fish. Instead, when rising fish are not present, cast your dry fly into likely looking holding water. You will often be searching the river with your dry fly for active fish rather than targeting a fish that is regularly feeding on the surface.


We are using 5X and 6X mono tippet for our dry fly fishing. We suggest mono when fishing with dry flies as fluorocarbon tends to sink, which makes it difficult to present a dry fly without introducing drag. 5X-6X fluorocarbon tippet have been the sizes our guides are using when nymphing.


We recommend using small, neutral colored indicators or hoppers/stimulators to detect strikes on your nymphs. Brightly colored indicators often alert the trout of your presence and they will either spook or simply refuse to eat until your indicator is long out of sight. 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.



Blue River Rainbows, ya gotta love em


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 and then again in the early spring. Streamer fishing is, at times, a surprisingly effective strategy on the most rivers 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 Pops 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!

Home tied flies are a great way to fool wary trout on the Blue River


The Blue River below Dillon Reservoir is flowing at 113 cfs. The feeder streams flowing into the Blue will increase that number slightly as it travels north towards Green Mountain Reservoir but not enough to be of any concern. The daily high water temperature in the Blue north of Silverthorne has been in the upper 50's

Bead head flies work much better on this stretch than they do in town. You can also use larger imitations of Midges, Caddis and Stoneflies, and worm imitations. Bring your 4X to 5X fluorocarbon tippet and a 5-6 weight rod when nymphing or throwing dry flies. The clarity has been very good lately and should not be an issue.


Nymphs: #16-#18 Tungsten Yellow Sallies or Iron Sallies, #116-#18 Standard or CDC Bead Head Pheasant Tails, #14-#18 Bit Hookers in red or black, #14-#16 Nick's Fat Caddis or Chronic Caddis, #18-#20 Psycho BWO's, #8-#12 Pat's Rubberlegs in tan or coffee, and standard or Tungsten CDC Hare's Ears in #16-#20.


Dries: #12-#16 Parachute Adams, #12-#16 Stimulators and #14-#18 Elk Hair Caddis. Royal Wulffs, Chubby Chernobyls and other attractor style patterns often work better than you might expect on the Blue River north of Silverthorne.


Streamers should also be in your box. You'll need to cover some ground but putting in the extra effort will often pay off with a big fish. In addition to the newer, large articulated streamer patterns, try some of the smaller old standards like Slump Busters, Autumn Splendors and Flash-a-Buggers.

The Colorado River is about a 45 minute drive from Cutthroat Anglers. It is a prime destination for fly fishing in Colorado


The mosquitos are now quite manageable from Parshall down to the Reeder Creek access. Fishing has been best under the surface on Trico nymphs and drowned spinners. We are seeing a few BWO's but the fall BWO hatch is yet to hit its full stride.


Visibility is currently excellent but is subject to some discoloration due to these pesky thunderstorms we have been having lately. The flow is 177 cfs above the Williams Fork confluence and 453 cfs below the confluence. Fishing is fair to good. The summer hatches are winding down. You will find active fish if you cover some river but not every fish in the river is on the feed. Expect that to change soon as the water cools and the browns being to fatten themselves up for their approaching spawn.


To imitate the Tricos that are hatching most mornings we are using drowned trico patterns in sizes 20-24, size 20-24 Sparkle Wing RS-2's in black and  black or standard Pheasant Tails in sizes 18-24. Other nymphs that have been working include a size 16 Nick's Fat Caddis or Latex Caddis, a size 16-18 standard Hare's Ears to imitate the Caddis larvae in the river. A size 16-18 Iron Sallie or Barr's Golden Stone is doing the trick for the Golden Stone Fly nymphs. A #8 or #10 black or Coffee Pat's Rubberleg works just fine for the larger Stone Fly nymphs. And a size 18-22 olive or gray Sparkle Wing RS-2 or a size 18-22 Split-Case Blue Wing Olive (BWO) nymph are working very well for the BWO nymphs that are currently available to the trout. 


An Elk Hair Caddis or Stimulator in sizes 14-18, a Parachute Trico or Spent Trico in sizes #20-#24 and a Gulper Special in sizes 18-20 are excellent choices for taking advantage of any top-water activity.

Fly fishing in Colorado on the Colorado River near Radium. The Cutthroat Angler guides will put trout on your line


FYI: The mosquitos are almost history for 2017. 


The river currently has 2-3 feet of visibility from Pumphouse to Dotsero. With the dry weather in this week's forecast we are looking at a fantastic week of fishing. As always, call the shop (970-262-2878) for the most current info. We have guides on almost all stretches of the Colorado River on a daily basis.


The fish are taking a variety of nymphs: Pat's Rubberlegs in sizes 8-12, Tungsten CDC Pheasant Tails and Double Downs in sizes 14-20, size 16 red CDC Copper Johns, size 20-24 Tid-Bits and UV Midges, Size 18-20 olive RS-2's and size 18-22 black or standard Pheasant Tails to name a few. If you keep your nymphs in the #16-#20 size range, with an emphasis on #16 and #20, you should be fine. (The Pat's is an exception to that suggestion).


Our guides have been using 4X fluorocarbon tippet. Many of our guides are fishing 2-4 foot dropper rigs under a #8-#12 Chubby Chernobyl and varying their weight depending on depth and the intrinsic weight of the flies being used. This set-up has been effective throughout the river but particularly in the shallow fast moving water and also the pocket water sections of the river. We are seeing decent interest in the larger hopper type patterns and very good interest in the nymphs that float under the large dry fly. 


We are also having good action hitting the banks with small dry flies (#14-#20). Effective dry fly patterns include: While #6-#8 Chubby Chernobyl's will get eaten, you will likely have better action using: #12-#16 Chubby Chernobyls, #12-#16 Stimulators, #14-#18 Elk Hair Caddis and Parachute Adams in #16-#20.  


Another good tactic is to use a 6-9 foot indicator rig to plumb the deeper runs in the middle of the river. Not many folks are fishing this way and it can be very effective, especially on the busy days when the fish living on the edges are getting pummeled by anglers. 


The streamer bite has been very day to day as of late. If the fish are interested in streamers you'll know pretty soon after giving it a try. Try changing sizes and colors a few times before giving up though. If you still don't see any fish flash or chase, go back to nymphing or throwing dries. The latter option being one you should definitely consider when you encounter low light conditions and fish seem disinterested in your nymphs.

Cutthroat Anglers in Silverthorne, Colorado has all the flies you need for fly fishing the Arkansas River. Let the guide service in Summit County and Silverthorne show you how to fly fish the Arkansas River


The action on the Upper Arkansas has been a bit on the slower side lately. The big summer hatches of Green Drakes, Caddis and PMD's are pretty much history. Fish are still taking grasshopper patterns and attractor patterns on the surface but they aren't dialed into the daily emergences of summer insects like they were a few weeks ago. The trout are still eating pretty well under the surface however, but you will need to dial back the size of your bugs into the #16-#20  range,


Nymphs to try:  Standard or Black Pheasant Tails (#16-#20),  CDC Tungsten Pheasant Tails (#16-#20), Sparkle Wing RS-2's in olive or gray (#16-#18), Nick's Fat Caddis (#16), Golden Stone nymphs (#16-#18), and Blue Wing Olive Nymphs (#18-#20).


Dries to try: Parachute and standard Adams (#16-#18), olive or gold Chubby Chernobyls (#14-#16), Elk Hair Caddis (#16-#18), olive Mini-Foamulators((#16), Stimulators (#16-#18), and Purple Parachute Adams (#16-#18).

A guided float trip is a fantastic way to fly fish and see the Arkansas River. Come book a guided fly fishing trip with Cutthroat Anglers


It's go time on the the lower Ark. This can rate 4 or 5 stars on any given day. Both float and wade trips are doing well.  The current 560 cfs level is plenty of water for floating and not too much water for the wade angler. Look to find the fish holding near to the bank, in the soft water and soft pockets of water created by river structure and in the deeper runs (the latter is especially true when the sun is blindingly hot).


The insects of interest to the fish right now are Stone Flies, Hoppers Red Quills and Pale Morning Duns (PMD's). Here's an example of a set-up we are using: #10 or #12 olive or gold Chubby Chernobyl to a #8-#10 black or tan Pat's Rubber Leg to a #14-#16 Tungsten CDC Pheasant Tail or to a #16-#18 Most Days Caddis. Play with you depth if you aren't having success and don't be afraid to twitch your flies to grab the attention of the trout. The mornings can start off slowly so do not be discouraged if you encounter tough conditions before noon.


If you are lucky enough to find fish rising consistently, try Simulators, Caddis patterns and Parachute Adams. If these patterns fail to do the trick, try trailing an olive, gray or mahogany RS-s behind your larger dry fly. Remember to skate your fly if the fish don't react to your dead drift. Bring fresh bottles of floatant and Shimazaki Dry Shake. We have also been getting a few of the bigger rainbows and browns to eat attractor flies like #6-#8 Chubby Chernobyls or #8 Fuzzy Wuzzies.

Fly Fishing the South Platte is a memorable experience. Make some memories with Cutthroat Anglers, voted best fly shop in Summit County 4 years running Midges and Tricos are the insects of most importance. 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.  Fishing has been fair to very good depending on the day........and the wind.

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

Muddy Creek brown trout caught by Cutthroat guide Tor Parker


Muddy creek is flowing at 148 cfs and is fishing well. The mosquito and deer fly hatches have been epic this year. If you can endure the bugs you should encounter very good fishing. Throw streamers if you don't see any fish rising. 


Have a look at the reservoir releases before heading to the Muddy, or any tailwater for that matter. It might make or break your day. Here's a must have link to the state's Colorado Streamflow page.

Colorado lakes are breeding grounds for some of the biggest, most beautiful trout in the state. Stop in our Silverthorne, Colorado fly shop for all the lake flies you will need


We have been spending most of our time fishing the rivers so we do not have a first hand report from Spinney. Several of our customers have told us that they have been catching good numbers of fish and some real toads as well. They have also mentioned that some folks seem to be struggling. Based on their descriptions, we think the folks not catching fish at Spinney are not being flexible/mobile enough with their location and set-ups.


If you aren't catching fish with your standard 6-9 foot indicator rig try going much deeper, like 12-18 feet. Or try fishing in tight to the bank with a shorter dry dropper rig.


We sell a slip indicator for fishing deep. If you haven't tried it, you might think about giving it a try. It releases once you are hooked up so you can reel the fish all the way into the start of your lead. It does not hinder the casting stroke or interfere with the playing of fish at all.


There are some real toads being landed on #14-#18 Chironomids, Callibaetis nymphs, Damsel Fly nymphs, and streamers. Stop by the shop if you need to beef up your lake fly selection as we have brought in several new patterns for 2017.

 The South Platte River holds a great number of trout. The smaller fish are relatively easy to catch and the bigger ones must be worked for

The mosquito situation is much improved but can they can still be an issue. Hopper dropper is the name of the game. Choose your favorite combo and hit it. You shouldn't need anything other than your standard attractor patterns (in sizes 16-18) like Pheasant Tails and Hare's Ears. Bring your favorite Yellow Sallie nymph as well. The fish in this area are usually OK with bead head flies but we are getting to that part of the season where it is wise to use flies without beads and a bit of tin shot to get your flies down.
