Henry’s Fork 6-23-18


Widespread rain, wind, and variable flows out of Island Park Reservoir and unseasonably cool weather slowed the green drake emergence along the Harriman State Park reach of the river.  With seasonably warm weather predicted to move in by Monday, look for this event to get into full swing. A few golden stone adults remain in Box Canyon and the Coffee Pot area, and PM caddis activity seems good up and down the river.  The grey drake emergence on the crowded lower river has been good. Look for crowding to ease on the lower river as flows in the nearby South Fork approach normal for the season and the stonefly emergence begins.


Small Streams 6-23-18

Bear Creek reduced

Many of our small streams not draining high country are finally shaping up for good fishing.   Consider trying such as Bear Creek, McCoy Creek, the Salt River tribs ( Jackknife, Tincup, Stump, & Crow Creeks), Beaver Creek, Birch Creek and Warm River. Give such as Big Elk, Bitch, and Robinson  Creeks a bit more time to clear and drop. By 4th of  July weekend the choice of small streams worth fishing will have numerous candidates. Remember that South Fork tribs Palisades, Rainey, Pine, and Burns Creek and the Blackfoot River and its tributaries above the reservoir do not open to fishing until July 1st.

Since Wednesday flow out of Palisades Dam has been decreased from 18400 to 15400 cfs.  The reservoir above remains at 97% of capacity and normal late June flow is around 13400 cfs out of the dam.  So it’s going in the right direction to begin aquatic insect hatches. Look for the big stoneflies to begin hatching sometime next week. Right now yellow sallies are showing up with hatches peeking at mid-day, but best fishing for now remains presenting big rubberlegs, San Juan worms and streamers deep from drop-offs.


Henry’s Fork 6-19-18


Green Drake hatch is going on in a good manner at the Harriman State Park reach of the river. Looks like the weather is going to improve soon to a more comfortable condition, so consider getting out to enjoy this great event before it diminishes.


South Fork 6-19-18

Flow out of Palisades Dam was raised yesterday to 22500 cfs (now 23200 cfs at Heise, 17900 cfs at Lorenzo, back up to 22900 cfs at Menan ).  Flow out of Palisades Dam was around 17000 cfs just a few days ago.  The present flow sure makes fishing a bit tough! Try any pattern that resembles a drifting earth or aquatic worm or a scoured out and drifting stonefly nymph, and present it deep.  Be careful as the current flow level makes for a very dangerous river.


Small Steams 6-19-18

Birch Crk

Bear Creek and McCoy Creek Roads are open, but with muddy spots thanks to our recent rains. Jensen Creek Road remains closed. The Ashton-Flagg Road is open with soft spots at higher elevation points. The Fish Creek Road is open to Teardrop Lake.  Most of our smaller streams are in reasonable fishing conditions but with high water. That means presenting such as San Juan worms, woolly buggers, and any pattern meant to imitate earth or aquatic worms deep works. Exceptions to these conditions include Birch Creek and Warm River.  Get in touch with us for info on fishing these.


South Fork 6-12-18

In the last few days flow out of Palisades Reservoir has dropped from 22300 cfs to 18400 cfs.  We have past the run-off peak in this part of the Snake River drainage. Now if we can maintain a similar drop in flow, we should have close to normal flows in the South Fork before the end of the month.  That would mean a return of the normal stonefly, caddisfly and mayfly emergences. For now look for drop-off for presenting nymph and streamer patterns. Do not overlook presenting weighted rubber leg patterns around this feature.


Yellowstone Park 6-9-18



Run-off waters are receding, but have a way to go yet on many streams.  The Firehole is fishing quite well with PMD and caddis life cycle patterns producing.  One of the best patterns to use here is a partridge and olive or partridge and orange soft hackle, size 12-16.   These are great emerger patterns for caddisflies and mayflies. Be sure to have some in that fly box! White miller emerger patterns will also work well. Also be aware of new closures to protect thermal features along the river.  Shoshone and Lewis Lakes are in good fishing shape, but be aware that trails are in soggy conditions with some snow remaining.  Best fishing on both will be from boats and when streamer and leech patterns are presented. Duck Creek is fishing well or nice rainbows. The meadow is wet and mosquitoes are out in good numbers as is the case in just about anywhere in the park.
