The Blue River North of Silverthorne town limits contains some beautiful public water and breathtaking views. Unfortunately, it does not boast the highest trout population in some of its public sections. This does not mean there no fish to be caught, but you may have to be patient and work a little harder to hook up. However, you do always have the shot at hooking the fish of a lifetime, a large trout that usually reside in private sections of the Blue sometimes venture into public waters. Happy hunting.
Nymphs To Try: pegged eggs, Biot Golden Stone size 10-14, size 8-10 Crane Fly Larva, Pheasant Tails and Hare's Ears of all sizes and varieties, olive or grey RS2 in size 18-22, Two-Bit Hookers in black or olive size 16-18, RS2 in black or grey size 18-22, also try a variety of midge larva and emergers.
Streamers To Try: Barely Legal olive/white, Home Invader tan, or black, Double Gonga rainbow, Slump Buster various colors, Wooly Bugger colors
Dries To Try: Parachute Adams size 16-22, Extended Body Blue Wing Olive size 18-22, Matthew's Sparkle Dun Olive size 20-22, CDC Morgan's Midge 18-22
November has brought colder than average temps and lots of snowfall, but the Blue river north of silverthorne is still fishable. It has not iced over yet, and we have still been seeing some sproradic Baetis and midge hatches. Don't expect fishing action to be hot, but some trout can still be caught feeding on Baetis emergers, midges, and larger resident nymphs such as golden stones. We have also been having som luck fishing pegged eggs as well.
The “middle” Blue has been decent, but we are getting into the time of year which can produce larger sized brown trout moving throughout the river system. Seeing a few Kokanee Salmon is also a potential, although it is reported that the population of salmon in Green Mtn Res. is very weak.
Productive techniques will remain similar to other months…size 8 - 14 attractor style nymphs drifted under a strike indicator, with smaller more realistic fair dropped off the back. Streamers are also normally more productive at this time of year, especially if you are seeking larger sized trout.
As far as hatching insects go, we have been seeing Sulphur Duns, Blue Wing Olives, midges, and a few sporadic Caddis and Yellow Sallies.
The Blue River between Dillon Res. and Green Mtn. Res. is hit or miss, but has been producing nice fish on some days. We have seen a few green drakes, a few Golden Stones, Caddis, and PMDs hatching sporadically. The best technique is currently nymphing unless you happen to hit a hatch of any of the bugs mentioned above. If that is the case try a shallow hopper-dropper or single/double dry fly rig.
The “Middle" Blue is currently sitting at 300 CFS, which in our opinion is a great flow for this section. The water is high enough to give the trout cover which makes things a bit less spooky, but is also low enough to provide plenty of “fishable” water for the angler. Active bugs at this time of year are Golden Stoneflies, a variety of Caddis, PMDs, Blue Wing Olives, and potentially a Green Drake or two. Midges are always a go to bug of course. If you don’t see bugs in the air or on the water, check under rocks or run a seine to find the most prevalent aquatic insects of the day. We recommend running a nymph rig unless you are seeing trout holding towards the top of the water column.
The "Middle Blue" is currently seeing about 900 CFS of water being released from Dillon Reservoir. These higher flows can reduce the number of potential lies for trout, but that means that any good holding water you find will be likely to contain trout. Higher flows in the Middle Blue can also encourage large trout from Green Mountain Reservoir to move upstream, as well as disperse some of the overweight fish that normally hide in the private sections of the river. Heavier nymph rigs and streamers are good choices at the moment.
The Blue River to the north of Silverthorne to Green Mountain Reservoir is fishing fair. Currently, about 100 CFS of water is being released into the Blue River from Dillon Reservoir, which is the “average” winter flow for the Blue. As more snow melts from the mountains, more water will be released from Dillon Reservoir until we start to see high “spring run-off” flows in the Middle Blue. While high water can be tricky to read and fish, it helps to spread out some of the infamous trophy trout that hide in both private property, and Green Mountain Reservoir. Don’t expect to catch a large number of trout or easy fishing, but keep in mind that run-off is a good opportunity to hook into large trout on the Middle Blue.
We are currently experiencing off-color water in the afternoons on warmer days. This is a good time to try worms, eggs, streamers, and larger nymphs.
While we do not wish to alarm anyone, please be aware that mountain lion signs are now fairly common on the lower river just above Green Mountain Reservoir. This area is often called Palmer's Gulch and the Blue River SWA.
