FlyCast River Forecast
Technicality: 3/5
After a slight increase early last week, flows on the Blue have held steady at 100 cfs and remain above historical averages for this time of year. This bump in flows has improved the fishing so get out there while you can. That said, trout here are still very selective and skittish. Do your best to sight fish and to keep a low profile when moving about the water. If we havent drilled it into your brain by now, small and simple is the name of the game. Trout here see countless stock fly patterns and can spot a fake from a mile away. Stick with the Tube Midges, Thread Midges, Zebra Midges, Mercury Midges or Black Beauties for the best results. If you are not seeing results on these patterns, go with something a little brighter in color. Try leading with a Rainbow Warrior, Blood Midge, or red Copper John. In the early hours, you will want to focus on the banks and outer seams. As the day progresses, focus your attention to the deeper runs and pools.
Ideal Days: Monday Through Wednesday & Friday

FlyCast River Forecast
Technicality: 3/5
Flows on the Blue dropped slightly in the last few days, but are now closer to historical levels. Trout continue to podd up in the deeper runs and pools so choose your water carefully. Water clarity is great so do your best to sight fish. We generally are not casting unless we see fish. Small and flashy midge patterns will be the key this week with elevated air pressure. Rainbow Warriors, Blood Midges, Bling Midges and Mercury Midges will all produce. Trail any of the aforementioned lead flies with something in the neutral color spectrum like a Black Beauty, Tube Midge or Top Secret. In the early hours you will want to focus on the slack water near the banks and as the day goes on move out to the deeper water. These trout are especially skittish right now with lower flows so keep a low profile and stick with light (6X) tippet and yarn indicators. It will be cold this week so give it some time before you hit the water. Trout will be generally sluggish and unwilling to move far for your flies.

FlyCast River Forecast
Technicality: 3/5
Flows on the Blue are up over the last several days and the trout are reaping the benefits of more holding places. While trout have spread out compared to previous weeks, they continue to hold idle in the deeper runs and pools. However, in the early hours they have been more prone to move into the slack water near the banks and outer seams. The double or triple nymph rig with small and simple flies continues to produce the best results. With the exception of Monday, air pressure is set to remain elevated through Thursday and air temps will hold well below freezing. As such, trout are going to be sluggish and feeding at comparatively lower rates. It is in your best interest to let the morning sit and wait for air temps to rise. Regardless, go with small attractor patterns at the lead of your nymph rig, followed by one or more smaller imitative midge patterns. The tail end of the week will warm up, but still be cold. During this time, air pressure will dip and trout will be more enticed by slightly bigger flies.
