The Uppers flows are around 1000cfs near Cameron, and ~800cfs below Hebgen lake. Water temps in the high 30's. The upper is beginning to fish quite well as the trout start to move out of their winter lies. Rainbows and browns have begun chasing streamers a little more, with swung presentations being particularly effective as of late. Rainbows are beginning to get into spawn mode, so be mindful of redds when wading and let em do their thing. Double nymph rigs with a pats and a midge, rainbow warrior, $3 dip, worm, or perdigon in black or red are our go to winter bugs. Eggs, worms, and smaller baetis patterns have also been effective. BWOs have been coming out in small numbers, but the bulk of the spring hatch is still ahead of us. If you see any sippers, they are probably eating a midge. Tie on a Griffiths, midge cluster, or even an RS2.
