South Fork

South Fork 11-27-18

At Heise Br. (640x480)

A good approach for winter fishing on the South Fork by wading is to concentrate fishing the pools and deep runs.  Presenting streamers and rubber legs patterns on sink-tip lines and short, stout leaders should be the most effective strategy. With the winter flows to be around 900 cfs, there are numerous locations to apply this approach, some of which offer hundreds of yards of easily reached water. We at the shop can suggest some good locations for visits.   Dress warmly and be sure your waders are in leak-proof condition!

The flow out of Palisades Dam is 938 cfs. That’s around the maintenance flow through the winter.  The current flow at Heise is  better for the fish at 1390 cfs.  There are plenty of walk-in wade locations, but there are places with some icing. Get in touch with us to learn some of the best locations for wading.

At Heise Br. (640x480)

Flow out of Palisades Reservoir was reduced to 1770 cfs last night.  Now there is an excellent number of places for walk-in wade fishing. Come into the shop so we can suggest some of the best of these to you. While top water fishing  through BWO and midge activity may stay constant for now, streamer and large nymph presentation will soon be the best way to meet action from large trout. It is also the time of year to pay attention to weather reports. For example, next week will feature a cool-off and unsettled weather.  Keep that nice warm clothing close by. Looks like you may need it!

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.

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.

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.

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.

Cut closeup2 (640x415)

Flow out of Palisades Dam was dropped last night to 6750 cfs last night, and may continuing to drop today. Current flow  of 7060 at Heise will drop further today. Look for flows to drop again later this week.  BWOs and Mahoganies are emerging from the South Fork, at least along the lower river.   Streamer action is also picking up.  Hoppers are abundant throughout, and fish near vegetated banks are responding to patterns cast toward them. Caddis provide evening action. So looks like autumn is bringing better fishing up and down the river.
