Henry’s Fork, June 23rd, 2020

The big stoneflies have come and gone from the river. Straggling goldens can be around on upper sections including Coffee Pot and wind blown into the Flat Ranch section. Now the big mayfly emergence array has taken over.   Green drakes are diminishing on the lower river, but flavs, gray drakes & PMDs are taking over to be accompanied with PM caddis and a growing amount of sallies.  The trick here is to find trout’s preference at a given time then present life cycle patterns for that preference.   If you want fly-fishing company, the Box Canyon to Riverside section is for you.

The array of mayfly activity ( minus gray drakes in number) continues on the upper river.  From the top end of the Mesa Falls Scenic Highway to view towards the river looks like a massive trailer camp. The Last Chance rest stop is full of parked vehicles, and there you can hear foreign languages and English language accents from all corners of the earth. Dozens of boats will pass you by along the river during a day of fishing. All this is for good reason: this section of the river currently offers arguably the best trout fishing in the country. So be patient and considerate if you plan a visit!

All sorts of hatches are taking place on the river. The lower river still offers golden stoneflies hatching along with PMDs,  PM caddis and green drakes starting. Hopefully gray drakes will join this array.  On the upper river golden stones predominate over giant stoneflies and green drakes will start being important any day. PMDs and PM caddis offer action almost everywhere. All this means this near best of all trout streams is attracting fly-fishers in numbers in accordance with the variety and number of aquatic insects for trout to enjoy.  You will certainly have company almost everywhere on the river whether you wade or use a boat. Be patient and diplomatic. Remember that many visitors are coming from areas not as fortunate as locally with respect to the pandemic impact and social unrest. Show them how lucky we are to live in eastern Idaho.

South Fork, June 13th, 2020

With flow out of Palisades Dam down to about 11900 cfs ( 13000 at Heise, 5800 cfs at Lorenzo), fishing strategy is very similar to what we suggested on Memorial Day weekend.  That is rubberlegs and streamers fished deep in faster water, Also consider San Juan worm, squirmy wormy, super renegade, and super-X patterns there and in softer water. Look for a modest BWO hatch in shallow riffles during afternoons and oncoming caddis at that time.

Forget about the Teton River drainage upstream in the canyon and in the valley because of flooding proportion run-off.   Just glances from U. S. Highway 20 at the adjacent flooded pastures and the snow remaining on the Teton Range west slope should be convincing enough to stay away for now.  Irrigation water continues coming down the lower Blackfoot River and will continue to do so in varying amounts throughout the summer.  Successful fishing there will be reduced to using streamer and woolly bugger patterns on sink-tip lines.  The drainage above the reservoir does not open to fishing until July 1st.  Palisades Reservoir tributaries are rounding into good fishing shape with presenting wet flies being the best approach. Sinks drainage streams including Birch and Beaver Creeks and Little Lost River are in fishing condition with wet flies and small woolly bugger types bringing success.  Salt River tributaries flowing east out of Idaho (Crow, Jackknife, Stump and Tincup Creeks) are in run-off modes.

Where is it?

Twenty-Four Mile Reservoir has been excellent fishing with best approach being presenting midge pupa patterns under an indicator after finding the taking depth.  Slowly trolled small leech patterns on an intermediate line also work. We have no recent information on Chesterfield Reservoir.    Damselfly life cycle patterns are working at Springfield Reservoir, but the stand-by midge pupa pattern at the taking depth produces best. Small black leech patterns also have been producing. From what we have heard, Daniels Reservoir still has good fishing at the far side upper end, but has slowed at bit.  The Harriman Fish Pond has good hold-over rainbows, but the weed growth there is big time.  This reduces frustration-free fishing to  surface fishing or patterns under an indicator.

Henry’s Lake, June 9th, 2020

Fishing is picking up on the lake even though weather came be a bit perilous.  We have reports of good fishing in front of the cliffs and due east in front of the county boat dock, both at moderate to deep water.  Leech and streamer patterns apply.  But really “good fishing is where you find it” applies to the lake.

Fun Farm Bridge (1024x768)

Golden stoneflies are coming out on the Warm River to Ashton section of the river, and some giant stoneflies remain.  Goldens will now work their way up the river and such as Box Canyon will be the next host.  The next big activity, soon to happen on the lower river, is that from green drakes. That activity, too, will come to certain sections of the upper river.  We are all hoping for a return of gray drakes in past intensities around the middle of this month on the lower river.  All these happenings and more to come are the reasons why this great and unique river attracts crowds of enthusiasts whether boating or wading.  Certainly the crowds can test one’s patience, but tolerance can come based on the fact that few of those present are lucky enough to have such a treasure on their doorstep as do we in east Idaho.

South Fork 4

Was it “the flush” that went through the river last week with up to around 20000 cfs out of Palisades Dam?   Who knows!  Now flows are down to summer levels again: 13500 cfs out of the dam, 14300 cfs  at Heise, 7400 cfs at Lorenzo.  So back to strategies we suggested in our earlier South Fork reports: Look for BWO activity at the top end of shallower riffles, continue trying soft water in runs and side channels with streamers and nymphs, use rubber legs and streamers in deeper, faster waters. San Juan and squirmy worm variations will work almost anywhere  in the river because those high flows of last week scoured banks enough to bring a bunch of annelids into the water.  So fish will be looking for these packages of easy protein.

Small Streams, June 6th, 2020

Birch Creek and Little Warm River remain the two best candidates for taking youngsters fly-fishing. All Teton River upstream tributaries are in a big run-off mode. Palisades Reservoir tributaries have run-off that has appeared to have peaked.

If you do not mind doing a 150 mile drive west from Idaho Falls, the Little Wood River in the Taylor “Beartracks” Williams Preserve is in good fishing condition with browns and rainbows running up to trophy sizes. When run-off is in a decreasing mode, woolly bugger and San Juan worm patterns are effective as fish look for annelids washed into the stream.
