South Fork

Jimmy's All Seasons Angler / South Fork (Page 5)

South Fork 10-8-16

Flow out of Palisades Dam was reduced to just under 3900 cfs (4600 cfs at Heise) early on 10-6. BWO and mahogany dun activity still attracts interest from trout up and down the river. With continued seasonal cooling, look for terrestrial insect activity to decline.  Increasingly we hear reports of improving streamer fishing, especially along the lower river.

South Fork 10-1-16

With flows consistent at around 4500 cfs out of Palisades Dam and the likelihood that further reductions are coming soon, walk-in wade fishing is becoming more attractive along the river.  Unsettled weather coming up means the BWO and mahogany dun activity will continue to offer good fishing. But as we move through October, presenting streamer patterns will become increasingly effective.

Flow out of Palisades Dam was reduced to just under 5000 cfs ( resulting in just over 5500 cfs at Heise) early yesterday. That’s more good news for walk-in wade fishing. The other good news is that the BWOs and mahogany duns are doing a great job attracting trout, especially on these cool, cloudy days.

South Fork 9-20-16

Late in the day of September 13th flow out of Palisades dam was reduced to 5400 cfs. With the reservoir currently at 8% of usable capacity, more flow reductions are a given.  The current flow and promise of more reductions to come is great news for the wading angler as more of the river becomes safer for walk-in wade fishing.  That’s particularly true for the near future as a storm is forecast for the rest of this week meaning that prime time for enjoying the BWO and mahogany dun emergences is coming up. When moving from riffle to riffle, try fishing hoppers with a rubberleg and small beadhead dropper fished over gravel and to the banks. Streamer fishing has been improving with good success being reported on sparkle minnows and kreelex minnows. Nymphing has been productive as usual with small rubberlegs and bwo or pmd nymphs being the golden ticket. If you find yourself in a riffle with picky fish, try fishing a swung soft hackle to entice picky fish.

South Fork 9-17-16

Flow out of Palisades Dam was reduced to about 7500 cfs Wednesday. That action took place in the midst of trout responding very well to BWOs and mahogany duns. Some unsettled weather appears to be coming into the area next week, so look for a repeat of fish working these two emergences. Also because Palisades Reservoir is down to 10% of capacity, look for further flow reductions coming up soon.

South Fork 9-13-16

The cloudy and stormy weather predicted for much of this week is bringing on BWO and mahogany dun activity on the river. Look for afternoons to offer the best chance for action, and don’t overlook pitching a streamer when cloudy or stormy conditions prevail.

South Fork 9-10-16

Since our last South Fork fishing report (9-6-16) flow out of Palisades Dam has been dropped about 2000 cfs. It now stands at about 7300 cfs which is about normal for this time of year. Allow a day or two and fish will adjust to this significant flow drop and respond to mutant stoneflies with full interest, will do the same to hopper patterns, and provide good riffle fishing. There has been a repeat of the 2012 whitefish kill on the river. Whether the cause is the same as the recent one on the Yellowstone River is yet to be determined.

South Fork 9-6-16

The stormy day we had on Sunday produced a BWO emergence in the canyon and below. So  it looks like the BWO and Mahogany dun activity is getting a start. Riffle fishing seems to be slowing, but with these events it can pick up.  Currently presenting soft hackled patterns in the riffles may bring a better chance for action.

The flow out of Palisades Dam has been consistent (about 9500 cfs) for several days, Consider, however that the thermal effect of water coming out of the dam during draw-down times, like now, diminishes by the time flow reaches Heise. This means the river can be cooler in its lower portion which can impact the density of aquatic insect hatches.

South Fork 8-23-16

Stable and good quality water means good fishing continues on the river. The Great Feeder has been shut down meaning more water in the river below Byington.  Mutant golden stoneflies are emerging. Wes Newman’s Super X has been around a long time, but it works as well as other patterns for these stoneflies. Chernobyl types also fished on top early and again late in the day are also a good choice. Using two nymph rigs  of small bead head patterns is the most productive approach for fishing drop-offs around riffles now that hatches have diminished a bit. Try caddislfy life cycle patterns in the evening, and consider pitching a streamer pattern after the sun leaves the water.

Fishing is holding up very up & down the river.   Near constant inflow from the reservoir and good water temps are the reasons.  A good general strategy is to begin early in the day with mutant golden stone patterns, then with the advancing morning switch to a double nymph rig under an indicator. The top fly should be a rubber leg pattern and the bottom a small bead head nymph of choice. As the afternoon hours proceed, concentrate efforts in riffles with PMD and pink albert emerger and dun patterns. As evening rolls around, switch to caddis life cycle patterns. As evening advances, consider presenting streamer patterns around overhead cover and around areas out of direct sunlight.
