Henry’s Fork

Henrys Fork 6-21-11

The warm weather has finally arrived so we’ll start to see a big variety of hatches on the lower river near Ashton.  Right now there are good hatches of pale morning duns and caddis and soon we should see  flav’s and green drakes. In the evening look for gray drakes. When we get these hatches all coming off on the same day you won’t see all types of insects at once. PMD’s and caddis will be the main hatches and the flav’s and green drakes may appear for only hour sometimes less.

The flow is a little high but the water clarity is good.


Henry’s Fork 6/17

Flows on the lower river have dropped again and Warm River to Ashton section is fishable again. Don’t forget about Ora to Chester stretch. Golden Stones, Salmon Flies and Caddis. No sign of Pale Morning Duns or Drakes yet. Stay posted and we will keep you updated as soon as we confirm they are hatching. The Stoneflies have moved all the way up to Box Canyon. The cooler weather and rain has prevented them from flying around but they are there and crawling. The best time to catch dry fly action on the stones in the Box is towards the late afternoon and evening.

The water is back up again on the lower Henry’s Fork from Warm River down. Due to a large amount of rain yesterday in the Ashton and Island Park area the Fall river and Robinson Creek are bringing muddy water into the system. Once the water drops again the fish will be looking up for the big Stoneflies and Caddis. The stonefly hatch has moved up to the Riverside campground area. Hiking into Hatchery Ford and below the Riverside campground will offer some very good secluded fishing. Stonefly nymphs and a bead head dropper or a Stonefly dry with a  bead head dropper should be very effective. Nymphing in the Box Canyon is still highly effective right now and I expect the stoneflies to be hatching any day now. If you need a up to the minute report call or stop by the shop.

The water on the lower river has been pretty dirty. Fishing on the river has been concentrated from the Box Canyon to the Warm River confluence.  However the flows on the lower river have been dropping fairly quickly and I expect this section to start fishing soon. Caddis and Stoneflies have been working. Don’t be afraid to throw nymphs but if you only want to throw dry flies….I understand. Feel free to call the shop for more details.


Henry’s Fork 6/8

You can find Stoneflies from Chester Dam all the way up to the Lower Mesa Falls. Timing is the key for catching this hatch. If you are getting refusals on a Salmon fly, change up to a smaller golder stone. Caddis and Pale Morning Duns should start hatching any day now.

Looks like the main push of the runoff is here. The Fall River at Chester is reaching flows over 7,000cfs making the river below Chester basically in flood stage. Warm River and Robinson Creek have blown out as well. There is good hiking and wade fishing around Mesa Falls and Riverside campground. Rubberlegs, Caddis Pupa, Rollin Stones and CFO Hummer Stones should produce fish.

Henry’s Fork 6/3

The big stoneflies have been making an appearance on the Henry’s Fork. They are in full swing below the Ashton Dam. They have also moved up to Warm River but are not hatching in large numbers on the Warm River to Ashton stretch. Fish rising on these big bugs is really day to day. I would fish the dry and float a stonefly nymph as a dropper. The high water has pushed the fish towards the banks look for the fish to holding there. If the fish are not actively feeding on the surface try throwing a golden stone or a chernobyl ant. Mixing up the presentation will sometimes trigger a fish to rise.

We have had a few reports of stoneflies at the Vernon Bridge and the Ora Bridge. When I say a few I am talking about a dozen nymph casings on the bridge. Not much flying yet but keep posted to the report and the weather report. Again I expect the hatch to really be in full swing by this weekend.

The water below Chester Dam still remains pretty dirty, temps will warm up this week and the Fall River will begin to run high again making that section difficult for fishing. Flows out of the Box canyon are staying steady at 2,000 cfs and the water is fairly clear. The water from Warm River down is Tea colored but very fishable. The stoneflies are almost ready to hatch and there are a few hatching. The main bulk of the hatch has not started yet. You can find nymphs staging along the banks fro Warm River down to the Chester Backwaters. With the warm temperatures expected this week I expect the hatch to be in full force about mid week. As always we will keep you posted as things progress.


Henry’s Fork 5/26

Flows have gotten pretty large on the Henry’s Fork. The lower river starting from Warm River confluence is pretty dirty and muddy. The river at St. Anthony is at Flood Stage. Water from the Box Canyon down to the Warm River is in pretty good condition. Fish nymphs under an indicator. Stonefly nymphs and caddis pupa are working well. There should be some dry fly caddis buzzing around but no report of fish actively feeding on the surface.

With the Holiday weekend coming up there will be a lot of people who migrate to The Box Canyon mostly cause its the only game in town. Just remember to be courteous and use some common sense.


Henry’s Fork 5/23

Flows have seemed to level off on the Henry’s Fork and the water clarity between Vernon and Chester is fishable and the fish are eating. The stoneflies are staging close to the banks and fish can be caught on rubberlegs and other stonefly nymph patterns. Caddis Nymphs and mayfly nymphs like Peasant Tails and prince nymphs. Bigger and brighter flies seem to be working better in the off color water. No Adult stoneflies yet but I expect to see a few later this week around the Chester backwaters.
