FlyCast River Forecast
Difficulty: Intermediate/Advanced
Flows on the Blue jumped another 200 cfs last week. As a result, trout are being pushed to the outer seams and slack water near the banks. This is great news for the fishery in general, but can make fishing more challenging. Nymphing continues to be the most effective mode of fishing. Stick with short clean casts and focus your attention closer to the banks. Increased flows means more mysis shrimp are entering the river and trout are having a heyday. Ensure you have a few of these patterns handy. Otherwise, small and simple midge and baetis patterns have been doing the trick. Despite afternoon rain showers throughout the week, youre in for a productive time on the water. Cloud cover will give trout a sense of protection and stable air pressure will make for consistent feeding rates.
Ideal Days: Tuesday through Thurday

The Blue Quill Angler
Clarity: Excellent
14 Day Forecast: Look for sporadic hatches of midges and a sporadic blue-winged olive or two. Flows are currently normal for this time of year.
Tips and Other Information: The Blue River in the town of Silverthorne is your best bet throughout the early spring months. Anglers should prepare themselves for sporadic hatches of midges and look for the occasional fish eating adults in the slower runs, deeper pools, and tailouts. Nymphing with midge larvae and pupae is your best bet right now, however. Dont rule out Mysis Shrimp, the trout are always looking for them. Target the transitional zones that funnel into the deeper runs and pools. Sight fishing is a must on the Blue River as the populations of trout are way down. Straight Creek is known to add some muddy water on warm days, so dont be surprised if the river gets off colored below the gauging station.
Effective Patterns: #18-20 Mysis Shrimp, #20-22 Medallion Midge, #20-22 Mercury Midge, #22-22 Black Beauty, #20-22 Red Larva, #20-22 Manhattan Midge, #20-24 Top Secret Midge, #20 JujuBaetis, #18-22 Mercury Flashback Pheasant Tail, #22-24 Chocolate Foam Wing Emerger, #18 Hot Tail Flash Egg, #20-24 Griffith Gnat, #22-24 Matts Midge, #22-26 Parachute Adams.

Flows on the Blue jumped another 200 cfs pushing trout to the outer seams and slack water near the banks. Now is the time to fish bigger bugs, particularly mysis shrimp. However, you cant go wrong with worms, eggs or stonefly patterns. When nymphing, we like to lead with one of the aforementioned flies followed by one or more smaller midge or baetis patterns. In the early hours, fish midge pupa/larva and as the day goes on lighten the load and fish some midge or baetis emerger patterns. As far as trailer flies go, keep them simple and let your attractor get their attention. At this flow, trout will spread out, but hold primarily in the slower runs and deep pools. In the afternoons, trout will venture out to the tailouts and riffles. Surface action has been decent with increased hatch activity. If youre looking to fish dries, seek out areas with cover like brush, trees and bridges as trout will be more inclined to feed here.
Ideal Days: Monday, Tuesday, Saturday & Sunday

FlyCast River Forecast
Difficulty: Intermediate/Advanced
Flows on the Blue increased dramatically over the last several days. As such, trout will spread out and feed on bigger bugs. Worms, caddis larva, stoneflies and mysis shrimp will make for great lead flies. The crowds are heavy so we encourage you to explore new water. While the water nearest the dam (Troutlets) seems to hold the biggest fish, they are growing increasingly selective. There is a ton of open water north of Silverthorne. The heavy nymph rig continues to produce the best results. Focus on the slack water near the bank to start, but as the day goes on look to fish the slow runs and pools. Hatch activity continues to improve and were seeing an abundance of midges throughout the day as well as BWOs in the afternoon. Trout here tend to feed less on surface flies compared to other locations, but will rise in areas with cover like bridges, brush and trees.
Ideal Days: Tuesday, Thursday & Saturday
