South Fork

South Fork 6-23-18

From Cpgd (640x480)

Since Wednesday flow out of Palisades Dam has been decreased from 18400 to 15400 cfs.  The reservoir above remains at 97% of capacity and normal late June flow is around 13400 cfs out of the dam.  So it’s going in the right direction to begin aquatic insect hatches. Look for the big stoneflies to begin hatching sometime next week. Right now yellow sallies are showing up with hatches peeking at mid-day, but best fishing for now remains presenting big rubberlegs, San Juan worms and streamers deep from drop-offs.

South Fork 6-19-18

Flow out of Palisades Dam was raised yesterday to 22500 cfs (now 23200 cfs at Heise, 17900 cfs at Lorenzo, back up to 22900 cfs at Menan ).  Flow out of Palisades Dam was around 17000 cfs just a few days ago.  The present flow sure makes fishing a bit tough! Try any pattern that resembles a drifting earth or aquatic worm or a scoured out and drifting stonefly nymph, and present it deep.  Be careful as the current flow level makes for a very dangerous river.

In the last few days flow out of Palisades Reservoir has dropped from 22300 cfs to 18400 cfs.  We have past the run-off peak in this part of the Snake River drainage. Now if we can maintain a similar drop in flow, we should have close to normal flows in the South Fork before the end of the month.  That would mean a return of the normal stonefly, caddisfly and mayfly emergences. For now look for drop-off for presenting nymph and streamer patterns. Do not overlook presenting weighted rubber leg patterns around this feature.

At Heise Br. (640x480)

Eventually the river will be at this level!

For the current really high water situation (21900 cfs out of Palisades Dam today!), don’t expect great fishing. But side channels, gravel bars and drop offs, where you an find them in a safe and cautious manner, nymph patterns we suggest include red or black zebra midge, copper john, both in size 12-16, rubberlegs in sizes 4-10, and San Juan worms and squirmy worms  in sizes 10-12. For effective streamer patterns try sex dungeons, sparkle minnows and peanut envys in as large a size as you can find.

We will suggest dry fly patterns when the river drops to a level when such patterns will be effective.

South Fork 6-2-18

With flow out of Palisades Dam over 20000 cfs the river below is dangerous. For now, expressing caution when approaching the river is important.  Palisades Reservoir is about 85% full, and water managers are trying to keep up with the high inflow and yet minimize flooding threats from the river below.  Flow into Jackson Lake has dropped significantly. Nevertheless there is potential for the river below Palisades Dam to remain very high through much of this month.

Flow out of Palisades Dam was increased to 19100 cfs Wednesday  (Now 19400 cfs at Heise, 14900 cfs at Lorenzo). With the reservoir about 75 % full and over 30000 cfs coming into it, an increase in outflow seems necessary.  However with irrigation water being taken out on a large scale, flow below Byington is about 14500 cfs which is about double for this time of year.  Water is discolored with suspended matter.  We have a few reports of exposed gravel bars and some fishing action below Byington where rubberlegs and brightly colored streamer patterns  sunk deep are interesting fish.  No dry fly action yet, but at least something is going on with respect to fishing on the lower river.  Above Byington it is best to try drop-offs and any gravel bars that are not in deep water. A weighted rubberlegs trailed with a San Juan worm trailor might be the best way to interest fish.

Henry’s Fork 5-22-18

Bear Gulch

 

Big bugs are out big time from Ora to Vernon Bridges and increasing from Warm River to top of Ashton Reservoir. But the same goes for float and wading anglers. Anywhere you try  in these areas you will experience REAL crowds of fly-fishers.  I hope you are exposed to good stream etiquette along these places. Whether you are or are not exposed to such, strive to be a good example of such. Understand that as the big bug emergence moves upstream, there are a number of location in which you can find minimized crowding. Try walking down to the river from the old Bear Gulch ski area. Best fishing here is upstream. Try the river from the Sheep Falls Road off Highway 20 or from the Mesa Falls Park just off the Mesa Falls Scenic Highway.  Try the river from the West Hatchery Ford Road from the Highway 20 side, or walk downstream from Riverside campground.  These and other unmentioned places will have more solitude, tranquility, and likely better fishing than the easily approached locations most folks frequent along the river.  Be assured that any big floating fly pattern resembling a giant stonefly will work; just place that pattern close or drift it by or under vegetation hanging over banks, beneath cliffs, around rocks above the surface, or any object protruding into the river.

FYI: Flow out of Palisades Reservoir was upped from 16000 cfs to 18000 cfs yesterday. So the days of equilibrium conditions on the river are gone for a while.  Palisades Reservoir is at about 60% of capacity.

It’s not all bad news for the South Fork, because nymph fishing seems to be improving.   Currently Palisades Reservoir is at 60% of capacity. Water coming out is cold, but clearing, and flow out of Palisades Dam has been nearly constant at 16000 cfs for about two weeks.  So stable conditions are present. Big rubber legs and stonefly nymph patterns work as do small bead head nymphs in riffles.

Flow out of Palisades dam has been constant at just under 16000 cfs for about a week. That’s a few thousand cfs higher than average and may not remain at that level, particularly if our weather warms. Palisades Reservoir is filling and is near 60% full.  Most effective fishing currently is through boating to present rubber leg patterns deep and the same for streamers under low light conditions.
