We are back warmer weather after a two days of chilly, rainy weather. The good news is the cooler weather helped drop water temps and add a little moister. So far so good for clarity issues, we don't foresee any mud coming from the drizzle.
Sallies, caddis, and Stoneflies have been the main hatches. Lots of fish are getting caught on nymphs, (anything tungsten with yellow in it has been solid). A rubber leg or a rubber leg with a tail has been working great as well.
For dries most guides have been running a chubby in the morning and a sally, caddis, trude, or ant in the afternoon. A few fish have also been caught on hoppers already, and plenty are hopping around in the grass...
Now is prime to to get out and fish on your own or to book a guide! Give us a call anytime... 1-406-222-7130.
