Flow out of Palisades Reservoir was dropped from about 4000 cfs to 3250 cfs (now 4260 cfs at Heise, 1600 cfs at Lorenzo) on October 1st. Hatches are holding up and streamers are increasingly effective during low light conditions. Walk-in wade locations are numerous, and we can suggest some of the best to try. So get in touch if you are considering trying some.
Notice the similarities between aquatic and terrestrial insect activity during September on the South Fork and the lower Henry’s Fork. The same applies to streamer pattern effectiveness. Look for these similarities to continue through October. These fall off some for the upper Henry’s Fork where aquatic insect hatches are more diverse and brown trout are absent. BWO activity and responding trout in any of these locations is reliable this time of the season.
Flow out of Palisades Reservoir has been steady at about 4000 cfs for a week. Good BWO activity and flow stability has kept fishing success up. Fall colors are making for beautiful scenery. October also brings notice that streamer fishing will be increasingly successful as brown trout migrate to spawning areas from Palisades Dam down through the length of the river.
Early AM tricos provide action on the Teton River. Later in the day BWOs take over. Look for terrestrial insect patterns to become less effective as colder weather takes over. The same will soon apply to the lower and upper Blackfoot River with respect to terrestrial insects if the stretch of predicted bad weather brings a killing frost. Forget trying small streams until next spring. They are now too cold and low to offer good fishing.
With unsettled weather coming up, streamer fishing for migrating browns is becoming very attractive whether from Warm River to Ashton or Ashton Dam on downstream past St. Anthony. Early or late in the day will be best regardless of weather.
