South Fork 07-23-09

The following is a report from Parker Stenersen(age 11) who fished four days this week with his Dad and friends.

“On the upper South Fork it was slow in the morning using a pink CFO Ant, but  we used a streamer on the banks and in deep swirly water to catch fish in the morning.

In the mid day you will want to find a rifel(riffle) with a deep truff (trough). The flies that have been working are a pmd  dun and a pink spinner.  Just hang on a  rifel and if its  not good but go find another and just wait there until 7:30 pm and the start using a CFO or streamer until dark. ” Parker Stenersen

Parker’s experience is what we are seeing from the Dam down through the canyon. The water is still very cool for  this time of year so we are not seeing mayfly hatches until 1 pm or so.

The lower river (below Heise) is picking up finally with good action with Chernobyls on top or a Bennett’s Rubber leg nymph with a San Juan worm dropper under water.

Lost on South Fork 7/21: Cabela’s 7-piece fly rod with Pfleuger Trion 1956 Reel. Reward. Call Butch Williams 307-690-2706 or email [email protected]


South Fork 7-22-09

Flow out of Palisades Dam remains constant at 12700 cfs with 13600 cfs at Heise, both flows almost right on normal.  The upper river still offers the best fishing.   A few goldens still hang around, but the best top water fishing is near the riffles after early afternoon when PMDs begin to emerge from riffles.  Be sure to have beetle and ant patterns for fishing grassy banks, overhangs, rocks and such.  Hoppers are small and just getting started.  Look for them to be important not far off.

Lost: Just above Fall Creek Falls-one mountain drift boat oar last seen floating downstream. If found please call Mike Medvecz @ 608-347-9594 or email @ [email protected]

Lost: Two fly rods on I-15 between Idaho Falls and Pocatello. If found contact Mike McDevitt 208-481-1331

Lost: Near Highway 33 Harrop Bridge on Teton River Streamdance Metolius fly rod with Ross Flywater reel.  If found call Quinn Grover  208-351-3894.


South Fork 7-20-09

Flow out of Palisades Dam has been stable at 12700 cfs for several days now, and the flow at Heise (13,800 cfs) has been just as stable.  And both flows are at historic normals.  All this means that the river, especially in Swan Valley and in the canyon, is at its summer best.  Some golden stones are still hanging around there, emerging yellow sallys and PMDs are bringing fish into riffles.  Bring your favorite  life-cycle patterns for  these remembering that presentation dominates specific pattern.   On the specific side, super-x patterns are living up to their  “fish-getter” reputations when swept under bushes, overhangs and along grassy banks.   Caddis flights bring evening action, and a few green drakes are beginning to show in canyon locations.  One should also pack streamer patterns for evening action around sheltered banks and shallows.  It’s a great time to be on the river, and look for the river to fish well for weeks to come.  Get in touch. We can give you advise not only on strategy, but equipment, best locations, and specific fly patterns.


South Fork 7-17-09

The flow has been stable at 12,700 cfs and we should see stable flows now through the balance of the summer. The big stones have pretty much finished but you may still move some fish on the bigger size 4 imitations as the fish will still remember them for a week or so after the hatch. There will still be good hatches of yellow sallies and pale morning duns through out the coming weeks so if our report seems torepeat itself its because we are going to have steady hatches all summer due to good flows and cold water.

The log that claimed several boats at the Fall Creek Falls has been removed. Until it was cut out it was one of the trickiest obstacles we had seen in a few years.

The flow from Heise downstream has dropped to 5,400 cfs and the fishing has improved from last week. We should start to see the summer golden stones appear down there in the newly formed riffles, brush piles, and channels. Look also for good hatches of PMD’s. A big Super-X  Renegade, Sculpzilla or Clouser will work if you are looking for a bigger fish or if nothing is going on top. This section of river has a lot of obstacles and tight channels so please be careful.


South Fork 7-16-09

Flow out of Palisades Dam has been steady at 12700 cfs for two days now.  This is very close to historic flows for this time of year.  And the river is clearing noticeably.  The golden stoneflies are numerous from the canyon into Swan Valley, and PMDs are emerging up and down the river.   The upper river provides the best fishing now.   With gravel bars emerging and riffles stabilizing look for a great season for fishing PMDs and later  mayflies all summer.  Come in or contact us about the best strategy and flies as the South Fork returns to it famous reputation for summer fishing.


South Fork 07-15-09

The river continues to fish well from Palisades down through canyon. Folks are still catching fish above Spring Creek on the big stones but the most consistent fishing has been with golden stones and the smaller yellow sallies. The flow has dropped a little more and is down to 12,700 cfs.

One note of caution about the upper river at the Fall Creek falls. On the left bank below the falls there is a log that comes out into the river and this week two boats hit the log and sunk. You can easily avoid this tree by staying on river right.

The lower river from Heise down has been fishing much slower than above. I don’t know the explanation for this but the flow has dropped another 2000 cfs since last weekend so we look for things to improve on the lower river.


South Fork 7-13-09

Big bugs are up as high as Irwin, and with flow out of Palisades down to 13000 cfs the river in Swan Valley is in great shape for fishing.  Bring your favorite dry giant and golden stonefly patterns!  The river is slightly discolored but this does not impact fishing.   Give a bit more time, and it will clear.  PMDs are out along the upper river, and with flows dropping more gravel bars are becoming available.  Big news for the lower river is that it is very tough to take out from the Twin Bridges site because the south channel is small and difficult to see as well as shallow enough to require pulling a drift boat through.  The river has formed a berm near the top of that channel.  But enough water comes up below this berm to allow launching from the Twin Bridges.  On the lower river try such such as rubberlegs and super-x’s.  The best action here can be had in and around springs that enter the river. Try midge pupa under an indicator or PMD life cycle patterns.

A rod inside a rod case has been found on the South Fork.  To identify & claim it, call 589-0385


South Fork 7-11-09

The flow is down another 1000 to 14,600cfs and the water is clearing nicely. About every type of summer bug is out including the big stones, golden stones, yellow sallies, Pale morning duns, and caddis. There are also a good number of Clackacrafts, Hydes, Alumiwelds and other assorted crafts floated down the river along with the bugs. Its a little cozy up there but the good fishing makes up for the crowds.

The big stones are in Swan Valley but I would still use them through the canyon for a week or more. We get asked where the big stones are countless times a day but I think most fish are caught on the smaller stones and sallies.

The good thing about a high and cool water year like we have is that the hatches will be consistent all summer. No slow down in late July and through August because of warm water temps.

We have been fishing Super-X’s and rubber leg nymphs in the mornings and evenings.


South Fork 7-10-09

Flow out of Palisades Dam continues to decrease. It was stepped down to 15600 cfs this AM, and it looks like further decreases may be in the works.  Although the river remains a bit colored, fish are responding quite well.  The big stonefly event is in the canyon, so the best way to encounter it is to float from Conant Valley downstream.  Try big nymphs as well as dry patterns, and remember presentation is more important than having a particular dry or wet pattern.  Yellow sally patterns continue to produce good responses from trout up & down the river.   PMD’s are now coming out big time.  With the river still higher than normal the best strategy for fishing PMDs is try life cycle patterns close to banks and at the shallower areas such as below islands or over visible gravel bars.


South Fork 7-8-09

The flow out of the Palisades has dropped to 16,000cfs which is what we were hoping for. The inflow into Palisades is also dropping rapidly  so we should see continued drops in the flows out of the dam. The riffles will now start to form again and the fish will move in against the banks instead of finding them up in the grass of the submerged islands.

There are great hatches of yellow sallie and golden stoneflies as well as pale morning dun mayflies. The big stones are in the lower canyon. The water is still off color and won’t completely clear for some time but the dry fly fishing won’t be affected by it. If anything the fish will be less spooky.

In the mornings before the the bugs start flying use rubber legs and Super-X’s. Streamers are a good choice too. When it warms up go to the dries.
