Fishing Reports

Jimmy's All Seasons Angler / Fishing Reports (Page 74)

Yellowstone Park 7-3-12

With the Firehole River warming up, everything else is shaping up. Caddis and PMDs (AM spinners, mid day to afternoon emergence) are making the Madison River in the Park a destination. Brown Drakes on the Gibbon River meadow reaches and on Duck Creek should be on your “to go” list for evening fishing. Green drakes are coming off in the meadow reaches of the Lewis River, below and above Lewis Lake.  The Ashton-Flagg Road is open giving access to Beula Lake.  Fall River Basin streams remain high because of snow pack remaining on Madison and Pitchstone plateaus.  A bunch of us carried float tubes down Delacey Trail to Shoshone Lake last Saturday. Getting out on the lake in those tubes was a blast with juvenile macks, browns and brookies responding to small leech patterns presented on full sink lines.  We had to place to ourselves!

Henry’s Fork 6-30-12

Following is a note from the Henry’s Fork Foundation concerning  the ongoing reconstruction work at Ashton Dam. In the meantime fishing conditions and fishing success should remain good.

Hi all,

At the Ashton Dam reconstruction project, they are having problems with the rubber seal over the upstream coffer dam coming loose, resulting in some additional sediment moving downstream.  To fix this problem, they need to send divers down to re-anchor the rubber blanket.  Since this work is being done next to the dam bypass tunnel, they will need to partially close the tunnel while they do the work.  However, as this is peak irrigation season,  they have to balance this work with downstream irrigation needs.  The result will be some major fluctuations in Henry’s Fork flows below Ashton Dam throughout the day.  Flows could fluctuate from 1200 cfs up to 3000 cfs, and this fluctuation may happen four times that day.  Idaho Fish and Game will be monitoring things that day.

 

Bottom line, Monday July 9th will be a day you don’t want to be fishing below Ashton Dam.

South Fork 6-29-12

Stream flow on the South Fork is stable with 13,600 cfs coming out of Palisades Dam, and 14,900 cfs at Heise. Nymph fishing in the morning with a Brown Rubber Leg ( size 8 ) and a Bead Head Crystal Pheasant Tail Nymph  dropper( size 16) has been the most productive till about 12 o’clock. From about 12 o’clock, riffles have been good with a CFO Yellow Sally ( size 16 and 14 ), and Olive Hares Ear Parachute (size 12) . There is a good emergence of salmon and golden adult stones along the bank near Heise, but fish still haven’t been eating them yet but that should change any day. Along with  yellow sallies in the riffles there will be good hatches of pale morning duns and some green drakes.

South Fork 6-27

Flows were bumped again yesterday afternoon to 13,000cfs. Again this is response to irrigation demand downstream. I don’t know how much more the water will increase but I will keep you all updated as soon as we know.

At this point I would only be fishing nymphs and streamers. The river has been raised 2,000 cfs in 2 days and that is a lot of water. Enough water to cool things down and slow any hatches that were happening and mix things up enough to have the fish a little confused. The good news is it doesn’t take long for things to settle down and the fishing to pick back up again. If we don’t have anymore increases tomorrow we will be back in action.

I had thoughts of Salmon Flies sometime this week but the increase in flows could very possibly push that back into next week. Call the shop for any and all questions or just stop by and we will be happy to help you.

South Fork 6-25-12

As you can imagine we are getting a lot of calls to see if the big salmon flies have started to hatch in the lower river around Ririe.  We still haven’t seen any of the big bugs but we are seeing a lot of yellow sallies and pale morning duns. The big stones should appear sometime this week.  Over the weekend we had had some good but brief action on the riffles in the afternoon. The most consistent action is still with nymphs and streamers.

Henry’s Fork 6-22

The Lower Henry’s Fork near Ashton has been fishing well. Early  morning fishing consists of an adult Golden Stone (CFO Flammer Ant size 6)  with a dropper such as a Red Copper John size 16. Noon fishing would be PMDs from 12 o’clock to 3 o’clock. From 5 o’clock to 7 o’clock Flavs (size 14)  were coming off with fish taking them on the flats. Finally from 8 o’clock to dark, an improved x-caddis tan size 16 and 18 was the ticket. There are also some Gray drakes.

South Fork 6-20-12

We wanted to give you an update on the water conditions and hatches for the South Fork .  We are seeing more Pale Morning Duns and Yellow Sallies each day from Swan Valley down river through the canyon. By late next week there should be big stones on the lower river near Lorenzo. The flow is still at 10,200 cfs and clear. Palisades Reservoir is filling slowly and if it does fill in the next week or so the increased flow should have little impact on fishing conditions and hatches.  Nymph fishing is still the most productive and some fish are taking Chernobyls from Byington down.

Henry’s Fork 6-14

Tomorrow is opening day on the Ranch. Caddis and Pale Morning Duns have been hatching in good numbers. I would have also have some green drakes in my fly box as well. We have not had any confirmed reports of Green drakes hatching yet. However don’t be afraid to fish one, if some of these flies have been hatching the fish will be looking for them. Golden Stones have been producing fish as well. We have had good success on streamers from Ora Bridge to Chester backwaters the past few days. Don’t let the off color water scare you away from this stretch. The water is off color but not that bad and some big fish have been caught on streamers and stoneflies.

South Fork 6-14

Fishing is getting pretty good on the South Fork. We have been hearing many good reports of lots of fish being caught on the gravel bars and the tailouts below the riffles. There is not much action on the bank right now but I would defiantly be fishing them between gravel bars. The streamer action is picking up every day. I have heard a mixed report on which streamer patterns are fishing the best. Be sure to bring a good selection with different colors and sizes. Fishing is still great with nymphs. big stonefly nymphs, yellow sally nymphs and an assortment of bead head flies have been working. Don’t overlook the san jaun worm, there have been many fish hooked on that fly.

We have been getting a lot of questions regarding the Salmon Fly hatch. As of right now we haven’t seen anything. I don’t expect to see any salmon flies until the last week of June. We all have our predictions but the truth is when they hatch we will let you all know by updating the fishing report.

Flows have stayed steady since the last increase over a week ago. Flows are 10,100 cfs. This is a great flow for fishing. This is also a great time to get out and do some fishing before all the crowds get here. The Canyon is really pretty right now and there is so secluded overnights to be had in the canyon for the next few weeks.

Henry’s Fork 6-11

I finally got the chance to fish the Henry’s Fork this past week and into the weekend. The streamer bite is definitely on during certain times of the day. Rubberlegs and bead head have been working when the dry fly bite slows down as well. Golden Stones, Simulators, and Chernobyl ants are bringing decent fish to the surface. Pale Morning duns have also been hatching is decent numbers.

Last week I reported on the float between Ashton Dam and Chester back waters being off color. I had a chance to float the section on Friday evening and I was impressed with the water quality overall. At the Ora bridge the water was good and about a half mile down got a little dirty but fishable. Than it seemed to clear up as we continued to float down the river. This section is not being utilized right now because most of the guides are concerned about the off color water so they are not taking clients down this section. We I floated into Chester at 8pm.  I saw lots of fish feeding on caddis and my truck was the only one in the parking lot. What I am trying to say is if you want some decent fishing with a chance to hook into a pig, float this section. No one is there and you will find the fishing to be good despite the water being a little off color.
