The past few days have brought us some well needed rain. It did rain in the Park as well, and the Lamar had a spike but it has come back down, the Yellowstone is off color, however, it is still gree .

With the lower CFS flows we are not too worried, the mud will reset the river and plus the bigger fish seem to slip up only when the water is a little off color.

There are still some nocturnals out early in the morning, especially way up high. Tungsten beadheads have been working well.  In the afternoon we have been fishing terrestrials (hoppers, ants, and beetles), as well as some smaller parachutes and mayfly imitations.   

Give us a call for more info or to book a trip!  1-406-222-7130.
