South Fork

South Fork 8-21-12

Flow out of Palisades Dam was dropped to 11,000 cfs last night. Let’s see what impact is on fishing, especially in riffles.  Several dead or troubled whitefish have been spotted in the river below Byington.  Reason for this situation is presently unknown.  But IDF&G requests if you encounter whitefish in trouble on the river, but still alive, retrieve them if possible.  Pack them on ice (Don’t freeze ’em!) and  take to the IDF&G office on Commerce Drive.   IDF&G is conducting analyses on collected whitefish in attempts to solve this situation.

Flow out of Palisades Dam stays around 124400-12500 cfs making for consistent conditions  including water temp. , currently about 64  deg. F.  That means fishing conditions have not changed much since our last report.  So for the time being continue to pitch chernobyl types, hopper patterns, and super renegades toward banks for good results. Expect spotty riffle fishing until flow out of Palisades Dam drops significantly.

Only a 100 cfs increase in flow out of Palisades Dam a few days ago.  So river below remains essentially at constant flow.  Hoppers and chernobyl types presented against the banks continues to outpoint riffle fishing on most of the river.  Don’t overlook the suggestion offered on trying the same with super renegades. Evening caddis swarms make for good fishing. With days shortening up evenings are earlier, so presenting these is more convenient.  Same goes for streamers which will become more important for those big browns as we move through the fall months.

No big change here.  Flow out of Palisades Dam is constant (12,400 cfs) and water temp. below the dam is 63 deg. F. Riffle fishing remains spotty. Some good overcast would help improve fishing there, but it is also possible that this is an off year with respect of numbers PMDs.  A few mutant golden stoneflies are showing up, but not as many as last year.  Keep on slamming the banks with chernobyl types and terrestrial patterns.  And do not forget to do the same with that old favorite the super renegade. Pitch it below overhead cover, pull it under, then away from that cover.  The “Super” may be out of style, but it remains one heckuva fish catchin’ fly!

Jimmy fished the lower river this weekend.  Hoppers and chernobyl patterns, sometimes with a small nymph trailing, brought good action.  So did Bennett’s Rubberlegs. From around 7:30 PM to dark he experienced a very good PMD emergence and spinner fall.  Riffle fishing this season has been sporadic, so might not hurt to consider fishing  riffles in the evening, based on Jimmy’s experience.

Please wear that life preserver you are required to have in your boat when on the water. Another tragedy happened on the South Fork. A lady drowned Thursday above Heise when a boat ran into difficulty on a side channel.  Life preservers were in the boat at the time of the incident.  Had they been worn it is likely that the futures of the persons involved would not have been impacted by this tragic turn.

The flow out of Palisades Dam was reduced to 12,500 cfs early today.  This action is could slow things for a day.  The hatches and patterns are pretty much the same as listed in earlier reports. It will be interesting to see if today’s drop is an indication of future drops or if the level will stay constant as the Bureau of Reclamation said last week. We’ll report what news we get.

Reports and our experiences on the south fork have been all the chart from good to slow. The folks who are fishing  different techniques through out the day have been the most successful. In this bright hot weather you may have to rely nymphs fished deep if the fish are not taking dries during the day. Streamers against the bank early in the morning and evening caught fish for us this weekend. There has also a good caddis hatch at night that has been getting the fish to the surface.

Riffle fishing has not reached its peak on the river.  Best riffle fishing method these days is to use dry-dropper combination.  Otherwise try  hitting the banks with your favorite chernobyl type big enough to support a small bead head dropper.  This technique has been working very well on the upper river.  Be ready to break out streamers at the end of the day.

From a fishing standpoint we have been fortunate to have stable flows below Palisades Dam for several weeks.   According to US Bureau of Reclamation it is likely that flow out of Palisades could remain constant through August to replenish water in American Falls Reservoir and to maintain flows for irrigation  just above the reservoir.  When water in the reservoir is at a comfortable volume to cover irrigation and demand for it just above the reservoir slows, look for flow out of Palisades to drop. We will be in contact with US Bureau of Reclamation to keep on top of flows in the South Fork.
