With all this blue winged olive weather you do not need any more hints as to what’s working throughout the river.  PMs are best, but nymphs early in the day will also be effective.

But do not overlook streamers!  Flows are low (1500 cfs at St. Anthony, 1100 cfs at Ashton, 300 cfs in Box Canyon above Buffalo River) so there is plenty of locations to present streamers during low light conditions.  Streamer fishing will be the most effective way to encounter large trout here as we move through the fall months.

Stormy weather should bring on more BWO activity and resulting feeding up & doen the river. The same is true for streamers on the lower river, so be sure to have both types in your fly box.  Trico action continues on parts of the river, but to enjoy the best of it you must be an early riser.   Terrestrial insects are still active and trout are interested in them, but killing frosts are coming.   So enjoy the remaining days when hoppers, beetles and ants bring action, especially on the upper river.


Henry’s Fork 9-26

Baetis should be in full swing on the lower river around Chester and Ashton. Overcast days will help these hatches. The brown trout are starting to get active as we get closer to the time when they spawn. We have had reports of brown trout starting to be more aggressive on streamers in the last week. Hoppers are still working well in the morning and in the evenings on warm days.


Henry’s Fork 9-24-09

Mahogany duns are appearing late afternoons on the lower river.  So are the tiny BWOs (#22-24).  No hard frosts yet, so those terrestrial patterns are still effective up & down the river.  If  you do not have streamers for evenings, better change that right now! Come in to see what we recommend  because as we move through the fall months streamers will be the best way to encounter the largest Henry’s Fork trout.

The wonderful late summer has slowed the fall mayfly emergence here.   We are getting colder night times, and stormy skies will be more frequent. This means the consistent BWO action and mahogany duns are coming, and streamer fishing will pick to make up for slowing action from terrestrial insects.   For now hoppers, caddis & streamers in the evening are the best way to find action.


Henry’s Fork 9-09-09

Same story for now: early & late in the day are best times to fish.  But we are not far away from changes up and down the river.  With cooling weather BWO and mahogany patterns will soon become more effective.  Same with streamers and even big nymph patterns.  Terrestrial patterns will gradually be less effective, but evening caddis swarms will provide good action.  We will keep on top of these changes and discuss here how you should adjust your fishing strategy accordingly.


Henry’s Fork 9-07-09

A good shot of cold weather would really help fishing here.  For now rely on best fishing to be early and late in the day ( AM spinner falls and streamers, PM caddis swarms, terrestrials, and streamers).  Best bet for daytime hours remains terrestrial patterns on waters with overhead cover.  Towards the end of the month BWOs and mahogany duns will bring action throughout the river.


Henry’s Fork 9-02-09

Early AMs (spinner falls) and evenings (caddis swarms, speckled duns) remain the best times to fish anywhere on the river.  During mid day terrestrial patterns along shaded banks are your best bet for action.  Small bead head nymphs work daytime in Box Canyon.  Streamers work there, at the Tubs, below Coffee Pot rapids, and along the lower river during evenings.

Kiss August, 2009 good-bye, and look for the river to host more action as we begin to cool off through September.  Evenings and early mornings remain the best times to be on the river until later in September.  Streamers will become increasingly important on the lower river when looking for action.  So will BWO life cycle patterns.  Also for the next month terrestrial patterns will be good choices anywhere on the river.


Henry’s Fork 8-26-09

Warm water has slowed action, especially on the lower river.  Stick to early mornings and evenings for the best chance of action.  Streamers near twilight offer a great chance for late day action on the lower river, in Box Canyon and below Coffeee Pot rapids.  If you must fish during daytime terrestrial patterns will be your best bet for action.
