Henry’s Fork

Keep watching the Henry’s Fork Foundation web site for developments and discussions on coffer dam situation at the Ashton Dam.  As Everet mention in his 8/16 “Today at Jimmy’s” report, we have Mike Lawson’s new book ” Fly-Fishing Guide to the Henry’s Fork” in stock.  This book has all of Mike’s angling knowledge on each part of this great river.  No one knows the river in its entirety as well as Mike.   This book proves it and sharing it demonstrates Mike’s generosity.  Mike offers that for several reasons August is his favorite month to fish the Harriman State Park reach of the Henry’s Fork.  That is right now, and the best source for strategy to do so is in his new book.   Come in and pick up a copy now, or get in touch to have us put one aside for your next visit.

Water seepage under the coffer dam is slowing construction on the Ashton Dam.  Let’s hope that seepage does not alter water management plans during the  project or impact completion target.  Keep in touch with the Henry’s Fork Foundation web site for the impact, proposals, and responses to this problem.  The lower river above and below the dam remains tough during daytime which is usual for this time of year.  Streamers presented in the evening and early morning brings best chance for meeting a big fish.  Streamers and spinner falls in the evening and morning along with evening caddis swarms make for best fishing on much of the upper river.   Terrestrial patterns presented close to the banks  just about anywhere can work during daytime but are sure to be more effective with cumulus buildup.   Those big fish moving out of the Outlet reach are in the river from The Tubs to Island Park Reservoir.  Expect recreational boaters down to Mack’s Inn during daytime, so evenings or early AM with streamer patterns may be the best times for fishing. Want to read some interesting Henry’s Fork commentary?  Go to Henry’s Fork Anglers web site and take a look at Mike Lawson’s August 9th Henry’s Fork fishing reports.   Mike offers valuable strategy gems for fishing the river this time of year, but also gives some thoughts on the crowds that frequent the river at certain times.

The lower river remains tough fishing.   The exception is to try streamers at twilight.  Terrestrials patterns are the name of the game during daytime on the upper river.  So is the early morning trico emergence.  Be stealthy–“Henry’s Fork Hunchback and all that” during these bright days.  Cumulus build-up will help your chances for success and also bring out some speckled duns and late season PMDs.  Evening caddis swarms can bring some action and fishing success then will pick up just about any time if you are grazed by a thundershower.

Anywhere you venture on the upper river terrestrial patterns will bring your best chance for daytime action.   This includes fishing along banks and around overhangs in canyon reaches.  During evenings look for caddis swarms and spinner falls to produce action.

Fishing on the upper river is best when terrestrial patterns are presented. Evening caddisfly swarms also bring action. With flow out of Henry’s Lake decreasing, larger trout are going to move downstream and out of the Outlet reach of the Henry’s Fork. Look for them to be present in the Tubs and on down through Coffee Pot to Island Park Reservoir.  Streamers presented in the evening would be the best way to encounter these fish.

Only the upper river is a Henry’s Fork destination now.  Terrestrial patterns will be your best bet, and so will visits early in the day and late in the day. Don’t forget that hair mouse!  Because flow out of Henry’s Lake is ramping down, big fish in the Outlet reach will move downstream. Might be worth trying big streamers in The Tubs, especially early and late in the day. When we begin to cool off in September, return to the lower river which will improve for fishing as we move through the fall season.

It’s time to use terrestrial patterns on the upper river.  Caddis swarms and AM diminishing spinner falls still happen, but those ant, beetle, horsefly, and hopper patterns seem most effective. Want to fish Box Canyon?  During daytime you will share it with innertubers and rafters.  So fish there very early in the day or fish from dinner time to twilight.  Bead head nymphs and terrestrial patterns presented tight to the bank still work.  On overcast days any kind of big stonefly nymph will attract interest.

We wanted to pass on the following information  from Kim at the Henry’s Fork Foundation concerning the boat ramp at Ashton.

All – We just received word from IDFG that the boat take-out at Ashton Reservoir will be completely closed on Thursday, July 26.  They will be seal-coating the parking lot and road down to the ramp that day.

 

Please share this information.  -Kim

Only significant change here is that flow out of Henry’s Lake has been dropped from 100 cfs to 71 cfs.  This drop in flow means especially larger fish in the Outlet section will begin moving downstream to find cooler water and more cover.  So the best fishing here is ending for the year.  Look for further drops in flow as we move through summer.   Elsewhere along the river start gearing up for terrestrial patterns being the most effective during daytime hours.

Time to consider terrestrial patterns for best chances of success on the upper river.  Flavs are well past their peak, and PMDs are smaller and less numerous.   Evenings and late afternoons continue to bring activity because of caddis swarms and mornings bring activity from spinner falls.  If you enjoy evening action from caddis swarms but want a bit more solitude, try the lower Coffeepot reach.   Flow out of Henry’s Lake remains at 100 cfs, so fishing on the river in the Flat Ranch Preserve will hold up until flows drop when water storage begins on the lake.  Look for evening caddis swarms, and PMDs emerging during late morning.  But again, expect to have best success  through presenting terrestrial patterns.
