Now is the time on the lower river to present streamers for migrating browns and rainbows stalking up for the winter.  With daylight savings ending, late afternoon fishing becomes more convenient for being on the river when large fish are more active.

Browns are active throughout the lower river, and streamers are the best way to encounter them especially under low light conditions.  For a change of pace try, BWO life cycle patterns especially during overcast conditions.

Migrating brown trout are bringing action on the lower river.  The recent stormy weather seems made to order for fishing here.  On these stormy days BWOs are bringing action there and on the upper river. Now is also the time to pitch streamers in Box Canyon and the Tubs above Mack’s Inn, weather permitting.

We fished the lower Henry’s Fork this weekend and had some good fishing. Nymphing was the most consistent, but if you had some clouds roll in and the wind wasn’t too bad, there were fish all over BWO’s. We caught fish on dries, but most of the nicer fish came on emergers dropped off the dry. Streamer fishing was also pretty good. All of the fish were in really good shape and were a lot of fun. Get out there while the weather is still decent!

Some of the best fishing on the river is taking place from Vernon Bridge  to below Ashton Dam where streamer patterns are attracting migrating brown trout.  To enjoy this event be sure to have bright and somber patterns available.  Other than this, do not be concerned so much with specific patterns. Be more concerned with presentation and timing. During daytime fish typically hold up in deeper runs and holes. They migrate mostly during low light, so you are most likely to encounter them during early light or sunset and twilight. Stormy conditions can also be a good time to encounter these fish. Looks like those conditions will be upon us during the coming week, so consider a visit to this part of the river then.

We just got an email from the Henry’s Fork  Foundation telling us that the flows out of Island Park Dam were recently dropped to 170cfs. The drop was agreed upon in last month’s Drought Management Planning meeting between the foundation, Idaho Fish and Game, the Bureau of Reclamation, and Fremont Madison Irrigation District. They are reducing the flows now to try and fill  the reservoir to ensure farmers with adequate water for next year. The flows will be raised again in the winter to provide more water for the young trout that need it to survive. We will update you all on any more information as we get it.


On another note the Ashton Dam project is nearly complete. Plans are to start filling the reservoir back up November 6th!

Fishing is continuing to pick up on the Henry’s Fork. Bring some streamers, nymphs and Blue Wing Olives. The streamer fishing has been really good below Ashton Dam. Box Canyon is fishing well, however its all wade fishing unless you want to beat up your drift boat. Things have slowed down on the Ranch. I would look for a cloudy day for action to pick up on the ranch. This is a great time to catch some big fish and have a little bit of solitude on the river.


Henry’s Fork 10-9-12

BWOs are active almost everywhere during afternoons when shadows begin to extend. If we get into cloudy weather, fish will respond to BWOs in better numbers, and hatches will be more intense.  It is also the time of year to present streamers for migrating browns. The section between Ashton Dam and Chester backwaters is a popular place to wade fish.  There are also locations for wade fishing below Chester Dam downstream to below St. Anthony.  From Warm River to Ashton Reservoir backwaters a boat will get you into the best fishing.  Pattern choice is not critical at these locations so long as your fly box includes somber and bright ties.


Henry’s Fork 10/1

Fishing has been good on the Henry’s Fork. Nymphing and Streamer fishing have been the main tactics for hooking fish. BWO hatches have been few and far between but look for those flies to pop during overcast and rainy days. The fishing below the Ashton Dam have been really good as well as Warm River to Ashton. Stonefly Nymphs and a variety or bead head nymphs. I personally like a large #14 or #12 Pheasant Tail below a rubberleg.
