With the storm that has moved in and this being a cold part of Montana, you might want to try a different area. It will be warming up later on this week with sun in the forecast for Saturday and a high of 40 s. This could be a good fish day. I recommend Blue-winged Olives and streamers. You can also try a Red San Juans for occasional trout. Give it another month or so and the Trout will be more active on the springs.
