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.


Henry’s Fork 9-29-18



The lower river offers a variety in dry fly fishing, and the turn in the weather predicted for next week can only help with respect to active fish.   Along the lower river terrestrial insects still inhabit banks in good numbers. BWO and  mahogany duns numbers will increase with the change in weather.  The evening caddis emergence continues. Streamer fishing is improving, and get even better with unsettled weather.  Tricos, a few remaining PMDs, and increasing BWOs make for good fishing in the Last Chance-Harriman section. Box Canyon offers good nymphing, with streamer fishing sure to pick up.  The river in the Flat Ranch is pretty much done for the season.


Main Stem Snake River 9-29-18



Have you noticed the number of boats increasing here?  That is because the river is dropping and big browns are beginning to migrate.  As is usual this time of year, they will take big streamer patterns especially early and late in the day.  There are a number of public accesses from Menan down to McTucker from which to begin and end a float trip. We will begin to receive information on where the best action is along the river, so get in touch if you are considering a main stem float trip or a walk-in wade outing.


South Fork 9-29-18

At 12500 cfs

Predictions say that the upcoming week will feature cloudiness, higher relative humidity, and possibly some rain in the region.  All these will be a “shot in the arm” for making the BWO and mahogany dun emergences thicker up and down the river.  Flow out of Palisades Dam will surely decrease from being relatively steady for several days, especially because the reservoir is about half full and storage for next agricultural season is on water managers minds.  Decreasing flows mean more walk-in wade opportunities. As we advance through October, look for streamer fishing to steadily improve everywhere along the river.  Best of all, the number of anglers will be down from now to till freeze-up.
