Fishing Reports

Jimmy's All Seasons Angler / Fishing Reports (Page 47)

Henry’s Fork 10-16-18


Notice that what happens on the lower Henry’s Fork (Warm River to St. Anthony) is similar to what is going on this time of year on the South Fork.  On both rivers flow is dropping to base level. BWOs, mahogany duns, and midges provide the best dry fly fishing.  Streamer presentation gains in effectiveness as the fall season advances through November as brown trout make spawning runs.  If switching to streamers is to your liking, the  best places on the upper river this time of year include Box Canyon, the base and the top of Coffee Pot Rapids, and The Tubs above Mack’s Inn.


South Fork 10-16-18


At Heise Br. (640x480)

Here is USBurRec intent for managing water flow out of Palisades Dam for the upcoming months: “Flow out of Palisades Dam will be reduced 523 cfs this evening, October 15, 2018. Outflow from Palisades will be 2,927 cfs tomorrow morning. Discharge out of Palisades will continue to be reduced over the next few weeks until ~900 cfs, where it will remain through the winter.” BWOs and diminishing mahogany duns continue to provide good dry fly fishing throughout the river.  The best way to encounter larger trout here is through presenting streamers.  For both types of fishing, low light conditions are best.


Yellowstone Park 10-13-18


It’s brown trout season with runs into the Lewis, Madison, and Gibbon River going in full swing.  The Gardner and Snake Rivers will soon be in that category.  If pitching big streamers is not your game, the Firehole offers good results for those presenting BWO life cycle and white miller patterns. Regardless of your preference, be prepared for wintry changes in the weather, and realize that fishing season closes after the first Sunday in November.


Still Waters 10-13-18


Daniels Res

Looks like you can find the best still water fishing around at Daniels Reservoir. The upper end is the best location there, and midge pupa under an indicator in relatively shallow water and small leech patterns are producing. Do not overlook presenting leech patterns back towards shore when wind strong enough to muddy the water (see above pic) arrives.  We have no reports on how Sand Creek Ponds are fishing. No news is not good news in this case.


South Fork 10-13-18


Just above Heise Br. (640x480)

Do not let that stair-step drop in flow out of Palisades Dam  (currently 3400 cfs, 4280 cfs at Heise, and 1730 cfs at Lorenzo) stop you from a fly-fishing visit to the river. Those flow changes, especially this time of year, are something the fish seem use to. Certainly there is less boat traffic on the river than just a few weeks ago and the dropping flow opens more walk-in wade locations.  Fly pattern suggestion remains the same; BWO, caddis, and mahogany dun life cycle, streamers, and rubber leg nymphs.   An overcast day, like today, will likely mean better fishing success than the nice days predicted to begin the middle of next week.


Small Streams 10-8-18

As flows approach base levels this time of year, fish generally are moving down from our head water streams to seek better cover.

Thus put such as Jackknife, Rock, Modoc, Wyoming Creeks on the back burner until next year.



Henry’s Fork 10-8-18



Bear Gulch

If you enjoy streamer fishing, now begins the time that Box Canyon is great, especially during a stormy day like today.  Another such location is “The Tubs” where Henry’s Lake Outlet and Big Springs Outlet combine above Mack’s Inn.  This time of year fish move downstream from the river in the Flat Ranch to the deep cover in these holes. There are several other locations along the river where streamers are very effective now. From Warm River to Ashton is particularly good. So is the river just below Ashton Dam. Want to pitch streamer patterns in a tranquil location free of boats?  Try the river at Bear Gulch, just above Mesa Falls Park, and below Coffee Pot Rapids as well as “The Tubs.”

If you enjoy the BWO emergence anywhere along the river, do not overlook using soft hackle patterns (partridge and olive , size 14) for emerger imitations.


South Fork 10-8-18



Just above Heise Br. (640x480)

Here is a note describing USBoR South Flow management for this week: “To account for decreases in diversion, BoR is decreasing flow out of Palisades Dam 470 cfs this evening (Oct. 8th).  Discharge out of Palisades will be ~5,230 cfs tomorrow morning. Cool, wet weather throughout the week will likely warrant another reduction in flow before the weekend. Anticipate a similar drop in flow Thursday night or Friday.”  BWO and mahogany dun life cycle patterns continue to produce.  As the month goes by streamer patterns will become increasingly effective.




Big Lost River 9-29-18

Big Lost

Flow out of Mackay Dam is a bit higher (around 250 cfs) than normal ( around 160 cfs) for the time of year, but the river can be waded here with care. Presenting BWO life cycle and terrestrial insect patterns are the ways to find action.
