Still Waters 9-13-16

Daniels Reservoir currently remains the best location for action. Midge pupa at the taking depth and underneath an indicator as well as damsel fly nymph patterns fished the same way or slowly stripped seem to work best.  The same approaches plus presenting small leech patterns is bringing action on Springfield Reservoir. Chesterfield and twenty-Four Mile Reservoirs have been slow fishing all season.  Because of introduced bass, plans are taking shape to poison Hawkins Reservoir to return it to a trout fishery for which it is best suited.

Small Streams 9-13-16

Look for terrestrial insect patterns to be important flies for action on most any small stream until a killing frost comes along. Another consideration is that with shortening days and cooler weather, and absence of AM trico activity, afternoons will be the best time to find action.  Also consider that with the uncertainties of a good snowfall this coming winter any tail water fishery (portions of Big Lost, Blackfoot, and Portneuf Rivers) will have low flows for the remainder of the season because of actions to fill depleted reservoirs.

South Fork 9-13-16

The cloudy and stormy weather predicted for much of this week is bringing on BWO and mahogany dun activity on the river. Look for afternoons to offer the best chance for action, and don’t overlook pitching a streamer when cloudy or stormy conditions prevail.

Yellowstone Park 9-13-16

Because of the Berry fire flaring up again along the John D. Rockefeller Memorial Parkway between Grand Teton and Yellowstone Parks, the south entrance road has been closed again.  Slough Creek campground and surroundings remain closed because of the Buffalo fire. When we receive info on these areas re-opening we will post such here.  The Norris Junction-Mammoth Hot Springs Road will re-open 7 AM, October 7th.

With respect to fishing, cooler weather means the Firehole River is offering improving conditions for fishing. Patterns for BWOs and caddis life cycle phases along with those for terrestrial insects will bring action. Hebgen Lake browns and rainbows are showing up in the Madison River, so streamer and large soft hackled patterns should be in the fly box.  On most other streams terrestrial insect patterns will bring best chances for action until a killing frost happens.

Yellowstone Park 9-10-16

If you intend to fish any of the Park streams that run through meadows, the choice of flies this time of year is easy.Take terrestrial insect patterns with an emphasis on those of hoppers. All of these: Bechler River, Boundary Creek, Duck Creek, Fall River, Gibbon River, Lamar River, Lewis River, Madison River, Slough Creek, Snake River, Soda Butte Creek, and others hosting large fish that relish hoppers this time of year.  If you arrive early in the day on some of these, look for trico swarms and fish actively feeding.

South Fork 9-10-16

Since our last South Fork fishing report (9-6-16) flow out of Palisades Dam has been dropped about 2000 cfs. It now stands at about 7300 cfs which is about normal for this time of year. Allow a day or two and fish will adjust to this significant flow drop and respond to mutant stoneflies with full interest, will do the same to hopper patterns, and provide good riffle fishing. There has been a repeat of the 2012 whitefish kill on the river. Whether the cause is the same as the recent one on the Yellowstone River is yet to be determined.

Henry’s Fork 9-10-16

Almost anywhere you try the river (excepting Box Canyon where two-nymph rigs bring action) early AM tricos then mid day hopper activity can be expected to bring most reliable action from resident trout.  We are cooling down, so significant BWO and mahogany dun emergences up and down the river are in the near future. Weather predictions are for some stormy weather this coming week, so these could happen within a few days.

Small Streams 9-10-16

We note that the flow out of Blackfoot River Reservoir was reduced significantly early today. Flow at the Shelley gauge is 128 cfs. Whether the flow stays at this level or not remains to be seen, but if it does, good fishing conditions are coming to the river about a month early. We will keep watch on how this develops. Meanwhile although the river above the reservoir is quite low, water temperatures are ideal. This makes for fish responding well to early AM trico activity and later in the day to terrestrial insect activity

Small Streams 9-6-16

Many of our small streams are impacted by the hot dry summer and therefore have lower than normal flows for this time of year. Given that condition, they heat up more quickly during daytime hours resulting in less dense aquatic insect hatches and lower fish activity.  Thus the best time to fish these can be during morning hours when waters are coolest. Some of these streams feature morning trico spinner falls which adds to their early in the day attraction.

Henry’s Fork 9-6-16

With respect to the lower river, the best thing is happening.  That is the weather cooling down which means sooner or later BWOs and mahogany duns will be emerging. On the river in the Last Chance-Riverside portion it’s still the same: morning trico spinners and terrestrial insect activity by late morning into afternoon hours are the best times to find action.
