South Fork

Jimmy's All Seasons Angler / South Fork (Page 25)

South Fork 8-14-12

Only a 100 cfs increase in flow out of Palisades Dam a few days ago.  So river below remains essentially at constant flow.  Hoppers and chernobyl types presented against the banks continues to outpoint riffle fishing on most of the river.  Don’t overlook the suggestion offered on trying the same with super renegades. Evening caddis swarms make for good fishing. With days shortening up evenings are earlier, so presenting these is more convenient.  Same goes for streamers which will become more important for those big browns as we move through the fall months.

No big change here.  Flow out of Palisades Dam is constant (12,400 cfs) and water temp. below the dam is 63 deg. F. Riffle fishing remains spotty. Some good overcast would help improve fishing there, but it is also possible that this is an off year with respect of numbers PMDs.  A few mutant golden stoneflies are showing up, but not as many as last year.  Keep on slamming the banks with chernobyl types and terrestrial patterns.  And do not forget to do the same with that old favorite the super renegade. Pitch it below overhead cover, pull it under, then away from that cover.  The “Super” may be out of style, but it remains one heckuva fish catchin’ fly!

South Fork 8-7-12

Jimmy fished the lower river this weekend.  Hoppers and chernobyl patterns, sometimes with a small nymph trailing, brought good action.  So did Bennett’s Rubberlegs. From around 7:30 PM to dark he experienced a very good PMD emergence and spinner fall.  Riffle fishing this season has been sporadic, so might not hurt to consider fishing  riffles in the evening, based on Jimmy’s experience.

Please wear that life preserver you are required to have in your boat when on the water. Another tragedy happened on the South Fork. A lady drowned Thursday above Heise when a boat ran into difficulty on a side channel.  Life preservers were in the boat at the time of the incident.  Had they been worn it is likely that the futures of the persons involved would not have been impacted by this tragic turn.

The flow out of Palisades Dam was reduced to 12,500 cfs early today.  This action is could slow things for a day.  The hatches and patterns are pretty much the same as listed in earlier reports. It will be interesting to see if today’s drop is an indication of future drops or if the level will stay constant as the Bureau of Reclamation said last week. We’ll report what news we get.

Reports and our experiences on the south fork have been all the chart from good to slow. The folks who are fishing  different techniques through out the day have been the most successful. In this bright hot weather you may have to rely nymphs fished deep if the fish are not taking dries during the day. Streamers against the bank early in the morning and evening caught fish for us this weekend. There has also a good caddis hatch at night that has been getting the fish to the surface.

South Fork 07-25-12

Yesterday Bruce called the Bureau of Reclamation and reported on the fishing report that flows will stay at or near 13,500 cfs for at least two  to three more weeks. In August we usually start to see the emergence of the wingless golden stones that a lot of folks refer to as mutant stones. The mutants generally emerge after the water starts to drop and more cobblestone is exposed.  With water level not dropping it may delay the goldens activity for awhile.  On the flip side we should have great year of hopper fishing. With a warm and dry spring we have a large hopper crop. Combine that with the dry vegetation conditions that will concentrate the hoppers next to greener bank vegetation and the river is bank full is why I’m thinking it could be great hopper fishing year.

Meanwhile the river continues to fish well.  There are a lot of different insects hatches so you could see everything from Pale Morning duns, to sallies, golden stones, and caddis in the late evenings.

Riffle fishing has not reached its peak on the river.  Best riffle fishing method these days is to use dry-dropper combination.  Otherwise try  hitting the banks with your favorite chernobyl type big enough to support a small bead head dropper.  This technique has been working very well on the upper river.  Be ready to break out streamers at the end of the day.

From a fishing standpoint we have been fortunate to have stable flows below Palisades Dam for several weeks.   According to US Bureau of Reclamation it is likely that flow out of Palisades could remain constant through August to replenish water in American Falls Reservoir and to maintain flows for irrigation  just above the reservoir.  When water in the reservoir is at a comfortable volume to cover irrigation and demand for it just above the reservoir slows, look for flow out of Palisades to drop. We will be in contact with US Bureau of Reclamation to keep on top of flows in the South Fork.

No significant change since the July 19th report. We have heard that golden stoneflies are emerging along the upper river and therefore providing good fishing for anglers slamming the banks with chernobyl types of choice.

South Fork 7-18

Fishing has been good on the South Fork. All sections seem to be fishing well. The Salmon Fly hatch has now moved through the entire river and fish can still be caught on Salmon Fly patterns from the Dam down through the canyon. Golden stones have been effective when fished tight against the bank.  The CFO Flamer Ant, Simulators and chubby Chernobyls have been working well for patterns.  Bead head nymph as droppers will pick up those fish weary to rise to dry fly. Run the dropper 18 inches to 3 feet below the dry. No consistency on PMD hatches, but we should start seeing those hatches any day now. Keep checking back as we try to keep this report updated.

South Fork 7-17-12

Conditions on the South Fork this year are those that have made it famed or fishing.  Water flows have not only been ideal for float fishing, but also nearly constant.  Insect activity has been nearly as expected, and weather, if a bit on the hot & dry side, good.  As a result visitations are up, not just through guiding operations but from visiting anglers prefering to go on their own experience.  Want to get away from much of the crowds?  Begin fishing about 6PM and stay on the water to dusk.  Riffle fishing will still be great with caddis taking over and there is the possibility of a spinner fall.  Try throwing a streamer when the light is leaving the river. Recently fishing slowed on the lower river because water has been shut down from the Big Feeder meaning increased flows in the river below. Given a few days the river will stabilize and good fishing will return.
