Henry’s Fork, June 9th, 2020

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.

Henry’s Fork, June 6th, 2020

The big bugs are in Box Canyon, and fish are looking for them.  This makes the choice of flies obvious: big floating patterns. The word is out, so look for a lot of boating and wading anglers there.  The green drakes should appear in numbers to attract fish on the lower river any day now.  This will help spread out fly-fishing interest on the river.

South Fork, June 6th, 2020

 

From Cpgd (640x480)

The river below the Palisades Dam is roaring because the flow has been raised to just under 20,000 cfs (about the same at Heise and near 14000 cfs at Lorenzo).  Tributaries to the the reservoir above are in run-off modes and discolor its upper end.  This is all from run-off in progress after a higher than normal snowfall winter.  Therefore expect high flows in the river below the dam for a while yet. Try streamer and rubber leg patterns DEEP in slowest water.

Yellowstone Park, June 6th, 2020

Although beginning to warm up, the Firehole River offers the best fishing in the park right now. Soft hackled patterns to simulate PMD and BWO emergers work well as do life cycle patterns for both. White miller patterns are another ” must have” item in that fly box. Also the smallish stonefly event in the canyon will offer wind-pushed big and golden stone adults into the river above, and you can bet the resident trout know what they are. With stormy weather predicted through most of the upcoming week, the Firehole River will be a great place to fish, but will also be well attended with fly-fishers. Consider giving Nez Perce Creek a try with above patterns, but be “bear aware” if you do.

Other places to consider right now in the Park including wading Lewis Lake shoreline to pitch streamers at cruising brown and juvenile lake trout. Some snow remains on the trail to the Lewis River channel above the lake, but if you can break through it to the meadow, the brown trout responding to streamer patterns there will offer great fishing.  Fishing in the Lewis River meadow below the lake offers a chance at very large brown trout, but they are the most cautious of browns anywhere.  Streamer patterns might offer the best choice in the Gibbon River below the falls and in Duck Creek.  Again be very “bear aware” at any of these locations.  The Madison River is in a streamer mode for now as post-spawning rainbows head back down to Hebgen Lake.

South Fork June 5th, 2020

Flows on the South Fork jumped up to 20,000 cfs today. At these flows your only real option is nymphing with big indicator rigs. There are much better options in the region right now to fish though, give us a call and we can get you squared away. If you are dead set on fishing the South Fork, be extremely careful!

Big Lost River, June 2nd, 2020

Flow out of Mackay Dam is on the increase and currently at around 450 cfs. This flow makes for tougher wading, which will become tougher as flow increases due to irrigation demands and because Mackay Reservoir needs room for upcoming run-off.
