Fishing Overview*

 Updated: 4/18/14  Thank you all for making last night's F3T a huge success!


On the warmer days, our low elevation snow is melting very quickly and finding its way into our "freestone" rivers and the lower reaches of our tailwaters. Our recent, cooler weather has helped abate the low level snow melt; providing us with a window of fishing opportunity on our "freestones." Time will tell if we are at the beginning of run-off or current conditions are just a brief hic-cup before we return to typical spring fishing conditions. Rivers currently most affected include the Colorado below Glenwood Springs, the Roaring Fork, the Eagle below Wolcott, and, to a lesser extent, the Colorado near Parshall. Clarity on the Arkansas currently remains quite good, even with the drop in flow. Update: As of yesterday, the colder weather has cleared most local "frestone" rivers to the point that they are stained but fishable. 


Our tailwater fisheries should continue to fish well over the coming weeks. While flows below most reservoirs are elevated, water clarity in the upper reaches of our tailwaters is good to excellent. The Blue River in Silverthorne, the Blue River below Green Mountain Reservoir, the Williams Fork, and the South Platte below Spinney reservoir all have very good clarity. Expect to find increasingly compromised clarity on the Blue River the farther you travel north towards Green Mountain Reservoir. 


As the water temps on most rivers are still relatively cold, concentrate your angling efforts on the softer water. But pay attention for changes in this pattern over the coming weeks; as water temperatures increase, and insect hatches become more frequent, the trout will be more willing to feed in heavier current in exchange for more food.


The Blue River is fishing nicely. We aren't seeing much BWO activity yet. Anglers fishing in town and north of town are doing well. Keep in mind that increases (and decreases) in river flow may cause trout to move locations. If your favorite spot isn't producing, it is possible that the fish have moved to nearby water that has more favorable living conditions. It is also worth mentioning that your favorite spot may not be fishing well simply because the Rainbows are into their annual spawn. There are certainly going to be days, or periods during the day, when the Rainbows have other things on their mind besides eating! Please don't pester paired up rainbows actively spawning on the cleaned areas of river bottom (i.e. Redds). Instead, target the mix of rainbows and browns feeding below the spawning rainbows.


While a variety of offerings will take fish on the Blue in town, Mysis Shrimp, Egg Patterns, San Juan Worms, and small, thin, thread Midges are your go-to patterns. As you head north from Silverthorne, add Attractor Patterns and generally larger flies to your arsenal. The flow this morning on the Blue River below Dillon Reservoir is 595, up from 495. The graph for Green Mountain Reservoir shows a release of 769 cfs, up from 722 cfs.

Water We Guide On

The warmer weather and recent increases in flow have both had a positive impact on the fishing on the Blue River in Silverthorne. On the warmer days, we are seeing some discoloration on the Blue River below Straight Creek. Think of this as an opportunity. The discolored water will help camuflage your indicator (and you) as you present your offerings to the trout. So far, we haven't seen unfishable conditions below Straight Creek.


The fishing in Silverthorne is always challenging but the persistent angler usually gets rewarded. The mornings and late afternoons/evenings have been less crowded but nice fish are being caught throughout the day. Small yarn indicators, as well as black and "Glow-in-the-Dark" Thingamabobbers, tend to spook Blue River trout less than large or brightly colored indicators. The same applies to flies without beads, especially metal beads.


Any dry fly activity usually occurs after the noon hour and can come and go until dark. 


Today's Tips: As the reservoir releases continue to increase this spring, be sure to try using 4X and 5X fluorocarbon tippet. You'll bring more fish to hand in the heavier water if you leave the 6X on its spool.


In the mornings and the evenings, the fish often seem particularly interested in eating Mysis shrimp. A good rule of thumb for Mysis is to use the more flashy patterns on cloudy days and the less flashy patterns-including clear Mysis patterns-on the brighter, sunnier days.


Robert (Rob) Quinlan, a friend of the shop from the Boulder area, sent us a very helpful email detailing the set-up he used over the weekend on the Blue in Silverthorne. Thanks Rob!


 "To share with anyone, everyone:  Two big beautiful 17 – 18 inchers and one nice 12 – 13 incher, all in about 20 minutes, just before sunrise.  Twenty steps upstream from the wire going across near the gauging station.  One on Charlie’s Mysis pattern size 16 and two on the fire-orange Desert Storm pattern size 22.  All flies bought at Cutthroat Anglers.  Two-fly rig dead-drifted with number 1 splitshot 6 inches up from lead fly and smallest thingamabobber about 4 feet up from weight.  Hope that helps someone else catch a trout.      Rob"


Fly patterns of all imaginings will produce fish on the Blue so don't be afraid to think outside the box. Although you can often use 5X tippet for your larger offerings, you should keep your tippet on the small side (6X, and 7X) for your smaller (i.e. Midge and BWO) offerings. Fluorocarbon is strongly recommended. We are seeing some fish push well over 20 inches. So pay attention to your drag setting and tie strong knots! Though not on fire, the Blue in Silverthorne continues to be a very good option.

The warmer weather has negatively impacted the clarity on the Blue River between Silverthorne and Green Mountain Reservoir. As of today, it is still fishable, especially in the mornings. Larger attractor patterns, San Juans and Egg Patterns have been effective of late. Expect to still find most fish holding in the deeper, softer water. 


We'll make it easy. Click here to order a selection of hand picked flies that consistently catch fish on the Blue River North of Silverthorne.

Patterns for this stretch:


Egg Patterns, Rainbow Warriors, Thread Midges, Standard Pheasant Tails, Prince Nymphs, Stonefly Nymphs of all sizes, and Tungsten CDC Pheasant Tails/Hare's Ears. Come on in and pick up Charlie's (Charlie is one of our guides) improved CDC Pheasant Tail pattern: the "TDJ". It is a must have addition to your box. The TDJ's extra weight and curved design makes it particularly effective during periods of high water and for making contact with trout holding in deep water.

Water clarity yesterday was about 1.5 feet. Fishing was a bit on the slow side but fish were caught. Size 20 midges were around most of the day but the fish weren't that interested in the eating them. Clarity will be a day to day affair. Call the shop for the most current info: 970-262-2878.


Nymphs for the Colorado near Parshall: Black, Brown, Olive Pat's Rubberlegs (Size 6-12), Tidbit Midge (Size 20-24), Olive or Black Zebra Midges (#20),Split-Case BWO's and Real Meals (Size 18-20), JuJu Midges (Size 18-22), JuJu Beatis (Size 18-20), Standard and Black Pheasant Tails (Size 18-22), CDC Pheasant Tails and Hare's Ears (Size 14-20), Buckskins (Size 14-18).


Dry Flies to Try: Parachute Adams (Size 20-24), Sparkle Duns, (Size 18-22), Extended Body BWO's (Size 18-20), Brooks Sprouts (Size 22-24), RS-2's and WD40's in the surface film (Size 20-26), Hatching Midges (Size 20-24), and Adult Midges (Size 20-24).


It is worth keeping in mind that the fishing above the Williams Fork confluence (think Paul Gilbert, Lone Buck and Hot Sulphur Springs) can be substantially different from the fishing below the confluence; you can think of it as fishing a different river. The water temperature of the Colorado below its confluence with the Williams Fork is usually significantly different than the water temperature above the confluence. 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.

The Colorado near Pumphouse is fishing fair due to rising flows, lack of insect activiry, and clarity isssues. The warmer days tend to fish better as the water temperatures are just beginning to creep over 40 degrees. If we can get a consistent BWO hatch rolling, expect the fishing to improve significantly.


We'll make it easy. Click here to order a selection of custom flies that crush on the Colorado River near Pumphouse.

Best Flies for this Stretch: #6-#10 Black or Olive Pat's Rubberlegs, #18-20 Red Copper Johns, #18-#20 Split-Cased BWO's , #16-#20 CDC Pheasant Tails, #18-#20 Psycho Beatis, #16-#20 Black Zebra Midges, #16-#20 Bead Head Pheasant Tails and Hare's Ears, #18-#22 Black RS-2's #20 Gray Sparkle Wing RS-2's, and Black WD-40's. Extended-body BWO's, and Parachute Adams are taking fish off the surface, especially after the noon hour. Streamers of all shapes and sizes are still productive at times but most days you will catch more fish by nymphing.

On the warmer days, the action on the Arkansas River near Salida has been good to very good. Midges, Baetis and molting Golden Stones are the thing this time of year. Keep in mind that Ark fish are almost always opportunistic. They will often eat a variety of offerings. Pat's Rubber Legs, Golden Stonefly Nymphs, standard Princes, Hot Wire Prince Nymphs and Bead Head Pheasant Tails will all take fish this time of year as well. Final thought, the Baetis nymphs on the Arkansas River tend to be very dark in color.

The Williams Fork is fishing fair. It will fish better if we can get some stability in flow. The Williams Fork is currently flowing at 328 cfs, up from 285 cfs. The fish we have been catching have been on: Miracle Nymphs, Black Beauties, Captain Hooks, Bear's BWO Emerger, Olive WD-40's, Egg Patterns, and Gray RS-2's.


Also give these patterns a try:


Use standard nymphs like Pheasant Tails, Hare's Ears and Midge Larvae. Egg Patterns, Prince Nymphs, JuJu Baetis, RS-2's, WD-40's, and Olive Zebra Midges are also working well. If you're not having any luck with the aforementioned flies try using Miracle Nymphs, Cream Crane Fly Larvae and Cream San Juan's. All of these flies have saved my bacon many a day while guiding on the Williams Fork. Streamers can also be effective.

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 a buzz

This report includes the “Tomahawk” and “Bull Basin” State Wildlife Areas.


Fishing is poor on these waters. Although the rivers are thawing, its been a cold, snowy winter down in South Park. It's a bit early yet for this area. But it shouldn't be too long before these areas begin to fish better.

Other Local Water

Because we do not guide on the following rivers, we cannot give the same detailed information that you find for the Water We Guide On. However, the streamflows are continuously updated, and we've done our best to give you a general idea of what to expect on these waters for this time of year. 

We don't guide this water but most of the shop guys love to fish here when they get a chance. The current flow of 769 cfs is very floatable but getting up there for effective/safe wading. At these flows, think twice before getting in the river. Most of the fish will locate near the banks and behind structure anyway so deep wading shouldn't be your primary strategy. Make note that the access down to the river is steep and can be very slippery.  




Mountain Lions call this area home. Please consider leaving your dog at home and keep a watchful eye when hiking/fishing. 


A variety of flies are working: Pat's Rubber Legs, Tung Teasers, Split-Backed BWO Nymphs, Barr's BWO Emergers, Olive and Black Zebra Midges,  Gray WD-40's, BWO's in Black or Zebra, Charlie's "TDJ" Pheasant Tails, Moorish's Anato Mayfly Nymph, CDC Hare's Ears, Buckskins, Standard Pheasant Tails in all sizes, Parachute Adams (sizes 14-22), Gulper Specials, and BWO Sparkle Duns.

The Eagle is fishing very well. Midge larvae, BWO nymphs, egg patterns and attractor patterns will do the trick. The Eagle has been very stained to muddy below Milk Creek which enters the Eagle just below Wolcott.


Eagle fish will eat a variety of flies. These include: Stonefly Nymphs, all variations and sizes of Prince Nymphs, Pheasant Tails, Bubble Back BWO's, Psych Baetis, Pink Rubber Worms, San Juan Worms, and Parachute Adams.

Gore Creek is running low and clear most days. Gore Creek has good numbers of fish. Some of which are surprisingly large. Although we rarely fish it ourselves, we include it on our report to encourage you to go give it a try. It is a fun place to fish. And though much of the Creek looks private, in fact, most of the Gore is open to the public.

A bit early for this, but it should begin to improve soon as we move into longer days and warmer weather. This is a very under-loved fishery. Not many of those around anymore! The Ten Mile inlet into Lake Dillon also holds fish. Hit the deeper pockets and seams. Wading and crossing Ten Mile shouldn't be a problem for the careful angler at flows below 100 CFS.

We don't guide this water but I've always found very willing fish from Idaho Springs to Georgetown. The fish are on the small side, with the occasional eye-opener, but it's a very enjoyable river to fish. Give it a try. It just might become you favorite place to get that "quick fix."
