South Fork 8-21-10

Riffle fishing is slowing as we move past the peak of the PMD emergence. Riffles still offer action especially towards late afternoon when caddis become active. With flows out of Palisades Dam just above 9000 cfs and heading lower, there is now an excellent choice of walk-in locations (contact us for some great walk-in candidates).    The plus side of  all this is that with fishing being great during evenings, most boat traffic is gone from the river, so you  have a better chance of solitude at walk-in riffles.  If you prefer float fishing, pitching hopper, chernobyl types and other terrestrial patterns against well vegetated banks is productive.   A great strategy is to trail a cinnamon ant pattern behind your hopper or chernobyl pattern.  If you are floating the river during the evening, your competition will be next to nil, and this will be the time to try streamers along  banks and other features out of direct sunshine.  As twilight approached big trout will come into the shallows to chase baitfish, another reason for carrying streamers if you are a late in the day fly-fisher.  This piece of info will become more useful as we move into the upcoming autumn months.

Terrestrial patterns are the way to go on all streams. Choose one you are sure to see on swifter streams, and delicate ones for slower waters. Horseflies and deer flies are rampart throughout.   No better pattern exists for simulating them than a standard humpy!  Another terrestrial pattern that is sure to work along wooded reaches are ones for spruce moths.  This is the peak of their season, and trout know it.

Still Waters 8-17-10

After being featured in last week’s Post Register Outdoor section, Sand Creek Ponds have received some attention.  Gulpers are providing late morning to early afternoon action in Pond #4.  Hold-over rainbows go more than twenty inches, and some fair sized brook trout can be found in the spring creeks feeding these ponds.   Best action can be had by launching a float tube or kick boat.  Ponds are motorless fishing only.  Consider trying adult damsel patterns here and on other still waters.   We have word of some good action resulting from presenting them on Springfield Reservoir.

Big Lost River 8-17-10

With flows out of Mackay Dam at just under 350 cfs, it is time to try the river where safe walk-in fishing is available. Flavs will emerge in the afternoon, and the peak of the trico hatch is not far away. That hatch will make for great action until mid day. Meanwhile terrestrial patterns will provide day time action, and action because of the evening caddis hatch will round out the trout fishing for the day.

Mainstem Snake River 8-17-10

A great place to try the river now is around Blackfoot and the Tilden Bridge areas. The flow here is around 2200 cfs meaning that wading is a safe option. Evenings are the best time to be on the river as trout will be chasing the caddis hatch and  large trout will chase baitfish in the shallows along sheltered areas.  Some action can also be found during early AM spinner falls.   At the Shelley Interstate-15 connector flows are still around 4500 cfs, but some walk-in fishing is possible especially about a mile below the connector downstream to Cook’s Diversion.  Grassy banks and undercuts will be the best places to find fish looking for terrestrial patterns. No doubt the best way to enjoy the river, however, is through a float trip.  Get in touch with us; we can help you choose a section to try.

Small Streams 8-17-10

Whether you float the Teton River, walk in to the Blackfoot River on the Wildlife Management area or try streams of equivalent character, terrestrial insect patterns are your best bet for  action this time of year. In Teton River canyon chernobyl types work well, and on the Blackfoot River with its slower flowing waters, traditional hopper patterns would be best.  Some of the smaller streams now at base levels (Robinson Creek) or having significant diversion for irrigation (Fall River) are warm, and action on them can slow.  There are some good exceptions to this warming.   Birch Creek (try attractor and terrestrial patterns) in the family area stays cools because of springs above and within the area.  Warm River (try attractor, PMD life cycle, sally, and terrestrial patterns)  below the spring will remain good fishing to the end of the season because the spring provides cool water in abundance. The same happens with Palisades Creek  (Try flav, terrestrial and attractor patterns) which receives cooler water from subsurface flows from the upper lake.  The lower lake also has an subsurface component to flow coming out.  Both these keep Palisades Creek water temps at best levels for trout and insect activity.

Henry’s Lake 8-17-10

Still slow.   Action can be had in front of Targhee and Duck creeks and at Staley’s, but  expect a crowd.

The road around the south end of the lake closes soon just east of the junction to Centennial Valley.  It will be closed for several weeks as a culvert is replaced by a bridge making for easier fish passage up Duck Creek.  Likewise, another culvert is being replaced further up the road to Centennial Valley to be replaced by another bridge for the same purpose. There will be a bypass at this construction allowing traffic to proceed to Centennial Valley.   For sure Henry’s Lake  cutts will benefit from these two projects.

Henry’s Fork 8-16-10

Slow on the lower river, but fair in the Island Park reaches.  For the upper river terrestrial patterns are your best bet for action on such as the Riverside to Hatchery Ford reach, Bear Gulch to Warm River and Harriman-Last Chance.  If you fish the lower river, late and early in the day are best times.  Rusty spinner, caddis, terrestrial patterns and streamer patterns will work during these times.

South Fork 8-16-10

With flow out of Palisades Dam at just under 9000 cfs, the river now has numerous walk-in fishing locations as well as being excellent for float fishing.  Get in touch with us to help choose best walk-in locations because for the rest of the season walk-in fishing will be a great alternative to float fishing.   What is going on “bugwise” on the South Fork?  Throughout the river emerging PMDs, sallys and caddis continue to make riffle fishing great, but with hoppers in good numbers, hitting the banks brings action similar to that during the recent big stonefly emergences.   A lot of folks are enjoying the South Fork’s great fishing these days, so be patient and considerate.   Remember: there enough trout for all to enjoy, but you want a little solitude on this wonderful river, get in touch with us—we know where & how you can find some there.

Main Stem Snake 8-07-10

The river is coming on strong as flows drop.   Walk-in places abound from Menan to the McTucker area just above American Falls Reservoir.   Get in touch with us to select one that fits your schedule and location.  Several sections of the river offer great float trips, and we can help you select one of these.  Even though it is late in the season , the river offers some mayfly hatches as well as fishing through caddisflies, sallys, and terrestrials.  But the river is best known for streamer fishing, especially during the late and early hours.
