Fishing Reports

Jimmy's All Seasons Angler / Fishing Reports (Page 6)

South Fork 8-28-18

 

South Fork 4

No change in flow here, currently flow is a bit higher than the average for this time of year, so reduced flows are coming up as irrigation season winds down. Stick to what we suggest in the  8/25/18 report for the South Fork. Mutant golden stones have moved into the lower canyon, but hopper fishing there seems more effective.

Yellowstone Park 8-25-18

 

upper slough (2)

For all Fall River Basin streams fishing success boils down to presenting trico life cycle patterns during AM hours and terrestrial insect patterns afterwards.  In slower waters speckled dun life cycle patterns can be effective.  Mosquitoes are mostly gone, but horse flies have taken over as top rated pest. Expect fishing success in all meadow reaches to slow during mid-day hours.   Same applies to all such streams in the Park and outside.

SF With Baldy 2 (640x480)

Flow out of Palisades Dam has been reduced to a bit over 9000 cfs (  9200 cfs at Heise,  4370 cfs at Lorenzo).  More safe walk in-wade locations are now available, and look for more to become available as flow will continue to drop as irrigation season winds down.  Riffle fishing has slowed a bit. Try #14-16 adams and purple haze in these. With the dropping flow mutant golden stones now coming out on the lower river  (see flow at Lorenzo), especially below the big feeder, should be coming out soon from the river above. Terrestrial patterns will be effective anywhere there is vegetated banks along the river.

Henry’s Fork 8-25-18

As with our small streams report, anywhere you try the Henry’s Fork be sure to have grasshopper patterns in that fly box these days. Other events attract trout including evening caddis hatches on most of the river, spinner falls, and speckled dun emergences on the slower portions of the river.  But nothing is as totally attractive to trout this time of year as hoppers.    Look out for recreational floaters going through Box Canyon, especially during weekends. Anyone seen any honey ants other than around the Harriman section?

Still Waters 8-25-18

Sand Creek Ponds 2

A fish salvage order is applied to Treasureton Reservoir. Looks like the future of all fish present is limited to a matter of days. Our warm dry weather lasting several weeks results in slow fishing, especially in the smaller, shallower lakes and ponds.  Exceptions include Daniels and Chesterfield Reservoirs in early AM hours where fishing at depth (ie midge pupa patterns under an indicator) can be effective.  Try bloodworm patterns around Island Park Reservoir springs.  Try fishing for warm water species at such as Condie, Johnson, Winder, and Glendale Reservoirs.  Or wait until October!

Small Streams 8-25-18

 

Conant Creek

Grass hopper patterns are essential for fishing area small streams this time of year.  There are exceptions such as patterns for the Big Elk Creek PM flav event, for speckled dun life cycle events on beaver ponds, for AM trico events, for PM caddis events, and for gray drake emergences on such as the Teton River. Hopper patterns, presented around overhead cover and water of good depth can be effective during these events.  Compared to mayflies and caddisflies, trout get more “bang for the buck”when rising to hoppers.  Its all about conservation of energy: how many rises does it take to gain the equivalent food value in mayflies or caddis flies compared to one rise to a drifting hopper?  The same applies to big stoneflies in season. So regardless of any other insect being available for trout, keep hopper patterns in that fly box for several weeks to come.

Henry’s Fork 8-18-18

Anywhere on the river cloudy skies and high relative humidity will improve your mid-day fishing success.  Patterns for spinner falls, caddis (life cycle patterns during evening hours) streamers, and terrestrial insects can be most effective during these times of day and under these atmospheric conditions. On the upper river the arrival of honey ants will boost trout’s desire to come to the surface any time.
