 When the reservoir spills of the Dillon Dam the water temperature in the Blue River increases dramatically. The warmer water often triggers the best summer hatches we see on the Blue River in Silverthorne


The Blue below Dillon Reservoir is currently running at 392 cfs. This is an excellent flow for fishing the Blue River. The fish are spreading 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. 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.


The water temperature behind the shop yesterday afternoon reached into the upper 50's. We had 57 degrees on our old mercury shop thermometer. When the reservoir spills of the Dillon Dam the water temperature in the Blue River increases dramatically. The warmer water often triggers the best summer hatches we see on the Blue River in Silverthorne.


Pale Morning Duns (PMDs) are hatching in good numbers in the morning into the early afternoon. We have seen them as early as 9:30 am but 10:30 am seems like the time that the hatch begins to heat up. We are also seeing a few Caddis but so far the numbers have been a bit sparse.


We are using 5X and 6X tippet for our dry fly fishing. We suggest mono when fishing with dry flies as fluorocarbon tends to sink, which makes getting a good drift difficult. 4X-5X Fluorocarbon tippet have been the sizes our guides are using when nymphing.


Even though the river is at a healthy 390 cfs, we still recommend using small, neutral colored indicators or a small hopper to detect strikes on your nymphs. 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.



The Blue River is a fantastic choice for fishing during run off. Our guided trips are available every day


Nymphs that are working include: Size 18-22 Mysis Shrimp (of all imaginings), standard and black size 14-16 Pheasant Tails, Split Case PMD nymphs, size 16-18 Military Mayflies, size 14 and 16 Chronic caddis in olive or brown, size 16 Fat Caddis in olive or brown, Gummy Worms in pink, brown or purple, size 18-22 black Pure Midges, and size 18-22 Chocolate Foam Wings.


Dry flies to try include: #16 Tilt-Wing PMDs, #14-#18 Sparkle Dun PMDs, #14-#16 Hi-Viz PMDs, #14-#16 PMDs Silhouette Duns, #14-#18 Elk Hair Caddis in olive, tan and brown, #14-#18 Peacock Caddis, #16 olive Chubby Chernobyls, #14-#16 Royal Wulffs, and #16 Shimazaki Ants. 


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 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!

Run off can be great time to fly fish on the Blue River in Silverthorne, Colorado. Try using the best fly shop in summit county, Colorado for all your flies and fly fishing needs


The Blue River below Dillon Reservoir has dropped from almost 1000 cfs last week to 390 cfs. This is a fantastic level for fishing the Blue River north of Silverthorne. 


Bead head flies work much better on this stretch than they do in town. You can also use larger imitations of Midges, PMD's, Caddis and Stoneflies, Eggs (particularly pegged beads) and worms. 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: #12-#18 Tungsten Yellow Sallies or Iron Sallies, #12-#18 Standard or Bead Head Pheasant Tails, #14-#18 Bit Hookers in red or black, #14-#16 Nick's Fat Caddis or Chronic Caddis, #16 Kingrey's Tungsten Biot PMD, #16 Tungsten Redemption PMD, #8-#12 Pat's Rubberlegs, and Tungsten CDC Hare's Ears in #14-#18.


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 well on the Blue River north of Silverthorne.

Elevated river flows often present excellent fly fishing opportunities. Our Silverthorne, Colorado fly shop provides the best fishing reports, flies and gear


The mosquitos are hideous below Parshall. There are far fewer blood suckers above Parshall at the Paul Gilbert and Lone Buck accesses.


Visibility is currently very good. The flow is 450 cfs above the Williams Fork confluence and 790 cfs below the confluence. Fishing is good to very good. There are plenty of Caddis, Yellow Sallies and Pale Morning Duns (PMD's) for your dry fly fishing pleasure. We are using Nick's Fat Caddis and Charlie's Chronic Caddis to imitate Caddis larvae. The Iron Sallie and Barr's Golden Stone are doing the trick for the Stone Fly nymphs. The Military Mayfly, black Pheasant Tails and the Split-Case PMD nymph are working very well for the PMD nymphs. We suggest fishing both your underwater and surface offerings mostly in size 14-16 but flies in #12 and #18 will produce results as well.

Float fishing is a great way to tame the high water conditions associated with run off.  Having the best Colorado River fishing report doesn't hurt either


FYI: Consider the Radium access closed until further notice. Apparently the boat ramps are open but there is no parking or camping as the BLM is using the space as headquarters to fight the Sheephorn Creek fire. We wish the firefighters the best of luck and pray for their safety.


FYI: The mosquitos are getting very active. Bring your bug spray. With any luck, the 2017 mosquito season will be a short one.


The river currently has 2-3 feet of visibility above Radium, 2 feet or more of visibility below Radium, and over a foot of visibility below State Bridge. Expect the river to clear even more as we get deeper into July.


The fish are taking a variety of flies: Pat's Rubberlegs, Psycho Prince Nymphs, Tungsten Yellow Sallies, Iron Sallies, Bubble-Back PMD's, Juju PMD's and black or standard Pheasant Tails to name a few. If you keep your nymphs in the #14-#18 size range you should be fine.


Our guides have been using 3X-4X tippet. While some of our guides are fishing longer rigs, most are fishing 2-3 foot dropper rigs under a #8 Chubby Chernobyl and varying their weight depending on depth and the intrinsic weight of the flies being used. It's a delicate balance, too much weight or depth and nothing but lost flies and snags fills your day. But if you run too short and light, you might throw a bagel (i.e., catch no fish). 


The dry fly fishing has been spotty but good enough to give it a go when the conditions are right. Barring a hatch of some sort, the lower light in the evening, the early day shade pockets along the bank, or overcast conditions usually yield the best dry fly action. When the fish are looking up, the action has been surprisingly good. And when they aren't? Well, you know how that song goes. While you will see the occasional #6-#8 Chubby Chernobyl get eaten, you will likely have better action using #12-#16 Stimulators, #14-#18 Elk Hair Caddis, #14-#16 Chubbies, and/or Parachute Adams in #12-#16.  


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, if the light is low, you should absolutely consider throwing dries, or a least a dry dropper set up.

There's nothing like taking the family on a guided fly fishing trip. Fly fishing is a family activity when visiting Summit County Colorado


The fishing is heating up on the Upper Arkansas. There was an amazing Caddis hatch today on the Hayden Meadow stretch. The Green Drakes and PMD's will be arriving soon. Fish are taking grasshopper patterns as well.


Nymphs to try: #8-10 Pat's Rubberleg in black, olive and tan, Standard or Black Pheasant Tails (#14-#16), Midge Patterns in red, gray or olive (#16-#18), CDC Tungsten Pheasant Tails (#12-#16), Sparkle Wing RS-2's in Olive or gray (#18), Green Drake nymphs in #12-#14, and Golden Stone nymphs in #12-16.


Dries to try: Parachute Adams (#12-#16), Chubby Chernobyls (#8-#12), Elk Hair Caddis (#14-#18), Foam Body Caddis (#14-#18), and olive Mini-Foamulators((#14).

While big trout like this one are rare on the Arkansas River, more big rainbows live in the Ark than you might think. Stop by our fly fishing store in Silverthorne, Colorado for the best fishing reports in Colorado


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 wade angler will be mostly fishing from the bank or very near to the bank. The flow is still 1300 cfs. Look to find the fish holding tight to the bank and in soft pockets of water created by river structure.


The insects of interest to the fish right now are Stone Flies, Caddis, Hoppers and Pale Morning Duns (PMD's). Here's an example of a set-up we are using: #10 olive or gold Chubby Chernobyl to a #8 black Pat's Rubber Leg to a #14 Chronic Caddis or #16 tungsten CDC Pheasant Tail/Charlie's Golden Stone. 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.


If you are lucky enough to find fish rising consistently, the fish will likely be fairly reckless and indiscriminating given the current conditions of the river. So Simulators, larger Caddis and Parachute Adams should get the job done. 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-#10 Chubby Chernobyls.

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.  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.

Check our Colorado fishing reports for the best flies for Spinney Mountain Reservoir. Visit our Silverthorne fly shop for the best flies and advice for Spinney Mountain


The Chironomid and Callibaetis hatches are underway and fishing has been very good in 12-15 feet of water. Some days will rate more than 4 stars but the action has slowed down enough that it no longer rates 4 stars. 

There are some real toads being landed on #12-#16 Chironomids and Callibaetis nymphs. Stop by the shop if you need to beef up your Chironomid selection as we have several new patterns for imitating the giant midges. The next month should provide some excellent fishing at Spinney.

A Williams Fork River brown trout


Bring 2 cans of bug spray with at least 40% Deet.


The Williams Fork is back to a very fishable 240 cfs. The Willy's Fork isn't easy at this flow but use enough weight and length in your set up and you'll be a happy camper. Along with the aforementioned weight, using San Juan Worms, Prince Nymphs, Pheasant Tails, smaller Golden Stones, Crane Fly Larvae, and Midges will bring results.

Whether you prefer the 12 oz., or you are all in for the "40," this creek is always flowing cold and foamy. Use limes and salt as needed. Longnecks are the preferred choice, but almost any variety will catch you a buzz.

Very buggy here as well but it's game on here as well. Hopper dropper is the name of the game. Choose your favorite combo and hit it. Fish are also taking Green Drakes, Yellow Sallies and PMD's. Use both the adult and nymph stage of the aforementioned insects and you will be a happy camper. The fish in this area are OK with bead head flies but as the summer gets longer in the tooth switch to beadless flies and a bit of tin shot to get your flies down.
