South Fork 7-07-14

First off, the South Fork is fishing great all throughout the river. The salmon flies are now all the way up to the Palisades Dam, but they are still in the canyon.  When fishing the big bugs, I would stop on a gravel bar and fish the structures like log jams, big boulders, and troughs. Along with the big bugs are PMDs, Yellow Sallies, and a big Caddis towards night.  If there is an overcast day, I would not be afraid to try a streamer. Therefore the selection of flies I would have, goes as such:

Trout Flies:

Super Chernobyl Golden Yellow (size 8 & 10)

CFO Pink Ant (size 8)

Improved Sofa Pillow (size 4)

Rollin Stone (size 4)

Small Dries:

Pink Comparadun (size 16 & 18)

Pink Albert CDC Biot Emerger (size 16 & 18)

Kyle’s Yellow Sally (size 12 & 14)

Goddard Caddis (size 14)


Bennet’s Seal Rubber Legs (size 6 & 8)

Beadhead Crystal Pheasant Tail (size 14 & 16)

Red Copper John (size 14 & 16)


Gallop’s Olive or White Sex Dungen (size 2)

Coffey’s Sparkle Minnow Sculpin (size 6)

Stenersen’s Lite Brite Minnow Rainbow (size 4)




South Fork 7-3-14

There is no significant change from earlier in the week with the types of insects and fly patterns. The fishing is very good and we are in the beginning of that time period on the south fork that everyone looks forward to. For those interested in the big stoneflies, they are out in good numbers above Cottonwood. Again we want to emphasize that there are many types of bugs out and you’ll find fish in different parts of the river eating different insects. Below is a list of flies that we will use for the next couple of weeks.

Big Stoneflies:

Rogue Foam Stone #4 and 6

Brett’s Stone #4 and 6

Improved Sofa Pillow #4 and 6

Golden Stoneflies:

CFO Golden Stone #8

Rollin’ Stone #10

Chubby Chernobyl  (purple and tan) #8 and 10

Yellow Sally Stones:

CFO Yellow Sally-X #12 and 14

Kyle’s Yellow Sally #12 and 14





Pale Morning Dun Thorax Dun #16

Harrop’s PMD Cripple #16 and 18

William’s CDC Pale Morning Dun #16

Harrops Pale Morning Dun Nymph #16





Super-X  #4

Sculpzilla (streamer) #4 and 8


South Fork 6-28-14

The fishing has been very good the past few days and should continue to stay good for the next couple of weeks. There are a lot of different bugs hatching so you will have the opportunity to fish many different types and sizes of dry flies. The big stones are up as far Wolf Flats.

There is some dry fly fishing on the upper river with pale morning duns but it will be a week or so before we see the activity there that we see now on the lower river. Nymph fishing with rubber legs or a pair of small nymphs has been good on all sections of the river.


Henry’s Fork 6-28-14

Add flavs to the list of mayflies emerging in the Last Chance-Harriman State Park area where fishing has been good. Still some green drakes and gray drakes with a few golden stones are left on the river below Ashton Dam.  Now that South Fork fishing is picking up big time, as Jimmy related a few days ago, there will be a shift of interest away from the Ashton to Chester part of the river and therefore fewer boats.  So with fewer anglers present from Ashton to Chester there is opportunity to enjoy fish responding to those drakes and golden stones before they die out.


South Fork 6-25-14

There is a nice variety of dry fly fishing on the the river now. Most of the activity is from Cottonwood downstream and usually starts by noon. There are good hatches of pale morning duns, blue wing olives and some green drakes. The golden stones and yellow sallies have started too. There are some big stones out below Heise.

We are having great success underneath before the hatches start with rubber leg nymphs, yellow sally nymphs and bead head flash prince nymphs. Streamer fishing against the bank and over the drop offs has been productive too.

The water level is at a normal flow of 13,000 cfs and has a green tint. It is has a little more color closer to Palisades Dam. We’ll post again tomorrow as Everet and I are leaving Tom and Parker to tend the shop and heading up to the south fork for the afternoon………




Still Waters 6-14-14

Twenty-four Mile and Daniels Reservoirs feature damselfly activity with fish responding. Try just about anywhere on Twenty-Four Mile, and concentrate on the upper end and creek mouth at Daniels. Some folks are having success just walking the banks at Daniels, thanks to our friend the wind causing wave action stirring up the bottom and so freeing up all sorts of food forms.  On both reservoirs fish also take midge pupa patterns under an indicator so long as you find the taking depth.  Hawkins Reservoir  also has fish taking damselfly nymphs, but its water level is beginning to drop because of irrigation demands. We do not have as much info on Chesterfield Reservoir, but based on what Twenty-Four and Daniels are offering there has to be some good fishing there with damselfly nymphs and midge pupa patterns.


Henry’s Fork 6-14-14

Fall River is clearing and dropping a bit, so the river below is shaping up. Gray drakes are out on the lower river from Chester backwaters to below St. Anthony. Add this to green drakes showing just above from the lower river, and you have a destination.  The Harriman State Park reach opens tomorrow, so expect crowds looking for green drakes there.  If you go there via US Highway 20, expects delays up to half an hour. Flaggers are active 24-7 on the Ashton Hill construction section.  Therefore consider traveling to Last Chance and above via the Mesa Falls Scenic Highway. Its a bit longer, but offers no through trucking and much less traffic.


Henry’s Fork 6-10-14

The lower river below Ashton Dam is beginning to shape up with PMDs emerging in good numbers and golden stoneflies appearing. Look for green drakes to start here any day. The same for gray drakes in the Chester backwaters.  The Warm River to Ashton reach is fishing well for those using caddis life cyle patterns, rubber leg nymphs, and streamers in the evening. At Last Chance PMDs are making an appearance and some march browns remain. The big stoneflies have just about finished their emergence with a few remaining in Box Canyon and a Coffee Pot.  Waters throughout the river below Island Park Dam are low as Island Park Reservoir is being filled. This means warmer water making for earlier emergences. Henry’s Lake is full with only 14 cfs coming into the Outlet. For now fishing there is slow.


Henry’s Lake 6-10-14

It appears that fish are moving away from shorelines and out into the lake. Trolling and presenting wooly bugger and peacock leech types is successful in deeper water. Use a fast sinking line to get down for the best action.  Beware of what the wind can during otherwise nice days.


Henry’s Fork 5-30-14

If you are following the big stonefly emergence, it is about over in the river from Ashton Dam to Chester Dam. Your best bet for enjoying it through dry fly fishing is to concentrate on the Riverside to Hatchery Ford and Box Canyon areas.  Expect a lot of boats, especially through the Box Canyon.
