Fishing Reports

Jimmy's All Seasons Angler / Fishing Reports (Page 17)

Henry’s Fork 9-3-19

Flying ants have arrived along the upper river, so add these to the grasshopper abundance, and terrestrial insect patterns of these should accompany your visit to this part of the river. Mayflies activity is reduced to a spotty trico emergence with some speckled duns thrown in.  Caddis are still active here, but seem to be less in favor than especially ants according to resident trout (and whitefish).  As always occurs this time of year, extensive weed beds put some limits on wet fly fishing and make escape havens for large hooked trout (and whitefish).

South Fork 9-3-19

Water flow and temperature remain constant (around 9800 cfs at Irwin, 10200 cfs at Heise, 5100 cfs at Lorenzo) and mayfly hatches seem to be holding up.  If you want to encounter fish looking for mutant golden stoneflies, best to be on the river at first light. Thundershowers and cooler weather are predicted for later this week. Hopefully this will help bring on the September BWO and mahogany dun activities because the current pink albert activity will begin to decrease with the onset of cooler weather.

Small Streams 8-31-19

Most small streams are down to base flows. For headwater streams this means larger fish are moving downstream seeking more overhead cover opportunities. Look for decrease in recreational boaters and boarders on the river in Teton Basin where dry fly fishing (hoppers, PMD, sallies) has been good.

South Fork 8-31-19

Flows and water temps remaining constant, but look for flows to drop soon as irrigation season is past its peak, and Palisades Reservoir storage will begin soon.  Pink albert and PMD action in riffles will drop, but riffle action will return with mid-September BWO and mahogany dun activity.

Fall Cr. Falls (640x480)

Consider the South Fork to be the “Tom Brady of Fly-Fishing” this season.   It shows no signs of slowing down with respect to quality fishing performance! Riffles, runs, side channels, and banks remain productive. Flow, water quality, and water temps  have been consistent and weather has been great.  The fall mayfly peak ( BWO, mahogany duns) is not far in the future, and indications suggest that event will also be another of high quality. So whether wading or boating,  look forward to more great fly-fishing experiences here before the snow flies.

Henry’s Fork 8-27-19

Cooler mornings and less daylight means we are heading in the direction of the lower river to begin “perking up” with respect to offering better fishing.  Look for the small BWO activity to become important in a few weeks and streamer fishing success to begin ramping up.

Southwestern Montana 8-24-19

The best chances for good still water fishing here is the gulper activity of which that on Hebgen Lake is the most renowned. Comparable hatches happen on other regional still waters, and many of those have fewer fly-fishing attendees. Elk, Hidden, Quake, and Wade Lakes are good examples where fewer fly-fishers means more unattended waters to enjoy.

No big change here since our last report.  Terrestrial insects “rule the roost” with respect to attracting trout just about everywhere on the river. Flying ants and trico spinners are coming closer to be available in important numbers up and down the river.  It will take a lot of cooling off and some weeks before the late season BWO hatch begins.
