FlyCast River Forecast
Technicality: 3/5
Fishing on the Blue is consistent with previous weeks. Flows are great and the water is crystal clear. Sight fishing is a must if you want to hook into one of these picky trout. This week will be cold so expect slow mornings and sluggish trout during this time. Nymphing will be your primary mode of fishing. Go with light (6x) tippet and yarn indicators so as to not spook the trout. Focus on the slack water near the banks in the morning and move out to the deeper runs and slower pools as it warms up. Weve had the best results closer to the dam so if you can manage to snag some river in that area you will be in good shape. Fishing near the Nike bridge has been productive as well, but anything lower than that has been quite the challenge. Trout here are feeding consistently on mysis shrimp as well as small midge and baetis. When nymphing, we like to start by leading with a mysis pattern, followed by Mercury Midge, Money Midge, Black beauty or Jujubaetis. While these are our go-to patterns at the moment, trout seem to be going for red midge pupa and larva patterns as well so dont be afraid to toss a red Zebra or Tube Midge into the mix. Were seeing consistent midge and BWO hatches so be prepared to fish dries. Trout here are fairly particular when it comes to where they feed on surface flies. Look to fish areas with cover like bridges and brush for the best results.
Ideal Days: Wednesday, Thursday & Friday

FlyCast River Forecast
Technicality: 3/5
Fishing at the Troutlets has been great and as more snow covers the slopes, you will see fewer anglers on the water. Trout here are pretty dang picky due to high angler pressure, but were hoping to see some more adventurous trout as more people exchange their waders for snow pants. Flows have held steady and the water is crystal clear. As such, light tippet (6x) in the fluorocarbon variety will put you at better odds of fooling these picky eaters. Small and simple nymphs are the name of the game. Focus on the slack water near the banks in the morning and as the day goes on move out to the deeper runs and pools. Do your best to sight fish and look for trout to pod up. We generally are not casting unless we see trout. This week is forecast to be a bit of a mixed bag with fairly erratic air pressure and sub-freezing temps. That said, cloud cover will work in your favor giving trout a sense of protection.
Ideal Days: Tuesday, Friday & Saturday

FlyCast River Forecast
Technicality: 3/5
The Blue River through Silverthorne has been impressively consistent. Flows have held at 103 cfs for the past month or so and trout behavior has been predictable. At this level, the water is gin clear, requiring stealthy fishing. Keeping a low profile and using a 10 ft leader and 6x tippet will help you fool these selective trout. While we have seen sporadic BWO hatches, nymphing is the most productive method of fishing. With a heavy nymph rig, hit the slow pools and runs. The water is cold, so dont expect to find many trout holding in the riffles or faster moving runs. Small and simple is the name of the game when it comes to fly selection. Midges in size #22-26 and baetis in size #20-22 will get the job done. Start with a double midge setup in the morning. Simple thread midges, Top Secrets, Black Beauties and Mercury Midges are all great options. In the afternoon, baetis emergers will get plenty of attention.
