Fishing Conditions

September 20, 2018

The Stone is still fishing well. We are starting to see a transition from hoppers and ants into baetis and streamers. Fall is on the horizon here in Montana and as such it is time to break out the sub surface patterns. The upper river and valley have been the hot spots the last few weeks. Carbella down to about mallards rest has been fishing consistently well. There are still a few fish willing to look up for the bigger foamy dry fly patterns but the bite is inconsistent at best. Additionally, with cooler temperatures, we are starting to see the afternoons fishing best. Prime time has been about 10 am to 1:00 pm.
