Montana Troutfitters is Bozeman’s oldest fly fishing shop Since 1978

Apr 01, 2025

The Uppers flows are 1020cfs near Cameron, and ~800cfs below Hebgen lake. Water temps 39.2. 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 reds when wading and let em do their thing. Weather has been erratic, so it's not a bad idea to bring an extra layer or two no matter what the forecasts says. Remember to remove gloves when handling fish. Nymphing is still producing lots of fish for us as well. 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.

FWP will be electrofishing VARNEY on April 1st. Please avoid this area during this time.
