Yellowstone Park 10-24-17



Brown and rainbow trout runs are the big attractions now. The run of Hebgen Lake browns and rainbows up the Madison River and mainly into the Gibbon River and the runs from Shoshone and Lewis Lakes into the channel section of the Lewis River have the most participants. The best locations for each of these events require specific activities for angling success. We at the shop can provide information that results in the best chances for enjoying these great angling events. Other brown trout runs in the park worth the effort to enjoy include Yellowstone River fish ascending the Gardner River and Snake River fish doing the same in the Snake River near the south entrance. All these runs are best enjoyed through presenting streamer patterns.

Earlier this week a new event, “Tie One On” came onto the Idaho Falls fly tying/fly-fishing scene. It’s first session took place during the evening (7-8 PM) of Tuesday, October 17th, at Tap and Fill, 1494 Milligan Road. “Tie One On” originated from ideas gathered by the Snake River Cutthroats and other fly fishing concerns to provide a forum for bringing fly tiers together to swap tying ideas, swap fishing information, and establish friendships.   The well-attended first session featured fly designer John Stenersen, of Clackacraft Boats, demonstrating streamer tying techniques using traditional and newly introduced materials.  The next session, slated for Tuesday, November 21st, same time and location, will feature Mike Glissmeyer of Idaho Angling Outfitters tying specialty streamer patterns for drift boat fishing.  “Tie One On” will be held at Tap and Fill, 7-8 PM, the third Tuesday of every month for the foreseeable future.  All interested fly fishers and fly tiers as well as the interested angling public, are welcome to attend.

Blackfoot River above graves creek

The best possible happening for resident trout in the lower Blackfoot River is that 200 cfs rather than 100 cfs is coming out of the reservoir. The result is that  trout have many deeper runs and pockets into which they can live with good overhead cover.  In recent years the scanty flows, sometimes less than 100 cfs,  reduced good living space to the deepest holes with resulting crowding. A few hoppers remain on stream-side banks, and patterns for them can interest fish. But the best fishing results from offering bead head nymphs, small streamers, and woolly bugger types.  BWO hatches continue to provide good afternoon fishing on Teton River in the Basin. The best news is that except for some duck hunters, most recreational boaters have left the river meaning fewer interruptions.


South Fork 10-16-17

03-12-09 South Fork 010

Not much has changed since our last report. Flow out of Palisades Dam remains nearly constant.  BWOs and mahogany duns continue to provide good riffle fishing, and their life cycle patterns are the best producers. Streamer fishing during low light conditions is very good.  There are many locations along the river for good walk-in wade fishing.  Get in touch with us because we can help you find some of the best.  It looks like the next several days will feature the fine autumn weather we have been missing for much of the season and back country roads will be in good shape. So get out and enjoy what the South Fork has to offer before real winter sets in.


Still Waters 10-14-17


Daniels and Hawkins Reservoirs currently offer some of the best still water fishing in the area. Midge pupa patterns presented at the taking depth and under an indicator and small leech patterns seem to be the best choices for action. With our current windy conditions fishing the edge of mud lines formed by wave action at Daniels will be productive when woolly bugger types are offered.  Next week IDF&G has scheduled Springfield Reservoir to be stocked with 1000  16″ rainbow trout.  Give these fish a number of days to get accustomed, and they will provide fast fishing but make it a bit tougher to encounter larger hold-over rainbows.


Henry’s Fork 10-14-17


BWOs and mahogany dun continue to provide good dry fly fishing up and down the river. Streamer fishing is best in Box Canyon, ” The Tubs” , and the entire lower river.  Considering the recent storm moving through the region, contact the Ashton District Office: 208-652-7442 to  determine if unpaved roads such as into the Hatchery Ford, Lower Coffee Pot and Tubs area (Below Big Springs and Henry’s Lake Outlet confluence) are open.

If you are looking at a trip to the interior of the park, it might be best to check its web site to see if roads to your planned location are open considering the storm that just passed through the area. Same recommendation with respect to trails to back country waters.  Right now would be a great time for a trip into Lewis River Channel to experience some of the best brown trout fishing anywhere in the region.  Presenting streamers is the name of the game. The only caveat is are trails to the river passable. Crowds certainly will be down considering the weather, so fish would be less disturbed.

Last night’s storm will make it difficult to reach some back country waters in the region until soon-to-come warmer weather melts the resulting snow accumulation. Then muddy conditions could prevail for a while on unpaved roads.  Some of the unpaved back country roads giving access to best small waters are used frequently this time of year by ranchers and farmers, so can be maintained because of demand.  For the next few days check with county road maintenance offices to determine driving conditions before attempting to reach waters “off the beaten path.”  Doing so might be a good idea for such as fishing visits planned for upper Warm River, Bitch and Robinson Creeks in Fremont County, Blackfoot River in Bingham and Caribou Counties, and Bear, Big Elk,  and McCoy Creeks in Bonneville County.


South Fork 10-14-17




Last night’s storm dumped 5-6 inches of wet, heavy snow in the Idaho Falls and surrounding area. This certainly will not hurt fishing, but getting there in some places could be a problem for two-wheel drive vehicles. Roads such as the South Fork road above Heise and the river road above the Swan Valley Bridge will lose snow cover quickly as sunshine and warmer temperatures return later today, but these roads could be muddy in places.  Boat launch locations should be OK to use. Flow out of Palisades Dam was reduced to about 3700 cfs last Monday (10/9) making the river even more attractive for walk-in wading, especially now when BWO and mahogany dun activity centered around riffles has been so good. Streamer fishing is picking up all along the river, and visits are slowing down. All this makes the present a good time for a visit as long as roads are passable.  We at the shop watch South Fork fishing conditions closely. Thus we can help you select a location for a visit as well as suggest a fishing strategy at any time.


Henry’s Fork 10-10-17

Bear Gulch

What we offered in the South Fork report apples to most of the Henry’s Fork as well. BWO and mahogany dun activities are resulting in great dry fly fishing just about everywhere along the river.  Flows are at or near historic normals everywhere above Chester. Below Chester  down to St. Anthony flows are slightly higher than normal because of higher than normal Fall River flows as has been the case all season.  Streamer fishing brings the best responses from large trout in Box Canyon and The Tubs, but is effective on most of the lower river.
